How To Remove Yellow Carpet Glue or Adhesive


Doing The Impossible - Removing That Carpet Glue From A Cement Floor.

If you have ever tried to remove that yellow carpet glue from under a wall-to-wall carpet or rug that you have removed from your floor, you know exactly what I'm talking about. You know how difficult it is. I have tried just about every chemical that is available at Lowe''s. You would think that someone there would know exactly what to do to remove it, but nobody does....(I've asked) and if they do, they aren't talking. I have just gone through this dilema and you won't believe it, but I have found a fix. Actually, it was not I who found the fix, it was my neighbor, who I would refer to as "extremely intelligent." After trying many different chemicals and cleaners, including Goo-Gone (I really thought it would work), and even after trying to use a heavy duty sander (wrongly recommended to me by a carpet store) that I had to rent from a machine rental place, I came to the conclusion that it was going to be impossible to remove the carpet glue from my floor. But I was wrong. My neighbor came over with what looks like a hoe but it is really a flat scraper. She told me to boil some water and throw it on the floor. After letting it sit there for a few minutes, under the hot boiling water, say, 5 or 10 minutes, the glue becomes softer and more pliable....and only then, one is able to scrape it off. Unbelievable! No chemical would remove it....no machine would remove it (it just made the coarse sandpaper one goey, sticky mess), but hot water did the trick! I then, used the $17.00 heavy-duty hand blade scrapers that I bought at Lowe's (I would say that this was the only great purchase that I made). I thought to myself, I have to share this with everybody, with someone else who is trying to do the impossible, who right now must be yanking their hair out in frustration, or banging their head against the wall. This WILL WORK. Believe me, don't waste your time and money buy going to the hardware stores to buy more chemicals because they won't work.

Don't Bang Your Head Against The Wall...

Don't Bang That Head...

Don't Bang That Head...

Even Though It's The Glue From Hell

Devil Glue Has A Fix - Boiling Water!

Thank you so much for this information!! I’ve been putting off tiling my hall bc of the glue!! I’m super excited to try this!!!

Lizette on October 06, 2015:

Your input proved to be quite valuable. Tenants glued carpet to a tiled floor. Hired a contractor who could not remove the glue by using harsh chemicals.

I was skeptical and thought this is to good to be true but tested it anyway. It was so easy to remove the glue!

Thank you for such valuable and easy solution to what seemed a nightmare.

Omg! Here you are maricarbo! I left a comment here 3 years ago. It was your hub that introduced me to Hub Pages. Been wondering what happened to you! Welcome back!

maricarbo (author) on August 22, 2014:

Thanks for all of your comments and suggestions, guys! Whatever works is good! I'm glad we are in the spirit of sharing!

Buy an Ultimate Scraper they work awesome for removing carpet glue.


chris on June 14, 2012:

You do realize that the "black mastic" has asbestos in it right? The yellow does not but I am dealing with yellow mastic on top of black mastic for some reason the people that put the carpet in thought that would be a good idea. However, We are in the process of ripping up the carpets and 4 rooms came up pretty easily using carpet cutters and spud bars. The last 2 rooms have such thick yellow mastic that it is actually ripping apart the carpet into threads. This is the biggest pain in the ass I have ever had to deal with.

I have not found a decent method to get the carpet up so we are trying a tile grinder today to see if that will do anything.

For the black mastic with asbestos in it, you can use a chemical found here:


It is very messy and will stain wood or other surfaces so you might need to poly off areas but when you apply it and wait 15-20 minutes this stuff can be removed with the stroke of a squeegee. Also you will need something to dry the sludge like qwik-dry and water to wipe things down afterwards.

queenma on June 10, 2012:

I would just like to say, OMGGGGGGGGGG. I've spent a lot of money to get that white crap of the concrete. I bought paint stripper and that took forever. I bought an electrical scrapper to help and that took forever. Thank GOD I came across this post. It's gonna make my life much easier. I have a 10x11 bedroom to do and I'm using this method for the rest of my home. Concrete staining is going in throughout my whole house. Thank You Soooo Much. :0)

KH on June 10, 2012:

You just saved us a bunch of money that we really needed. Bless you.

Joyce on May 28, 2012:

BRILLIANCE!!! We are changing indoor/outdoor carpeting on our pool deck. We used VERY hot tap water and it worked!!!

Penny on March 23, 2012:

Amazing! Boiling water & a shovel turned a nasty mess into a manageable clean up... Thank you!

christine on March 20, 2012:

Try a hot clothes iron. Put down a thin rag, like part of a t-shirt, and apply the iron for several seconds, then lift it and scrape of the glue.

Pam on March 07, 2012:

Wow! I just googled how to remove carpet glue from cement flors and found your information. Awesome I tried it on some spots. Yea it works. It will take me time because, I have other jobs, but I am going to finish hall floor, then paint walls and then paint floor. Yea! I hate the old carpet in house and can not afford anything. This is wonderful. I wish I could start now but have to go and tutor. thank you, thank you

Joan L on February 29, 2012:

Wow! thanks for the tip. I am 70 yrs old and just got the carpet up in my garage. I sure will try your water tip. I may have it all up by the time I am 71!

Now on to painting the pink walls the previous owners left. Ugh.

tmceasyfit.com on February 22, 2012:

hot water is fine but it may swell base materials

I have just had the horrible job to remove 260 sq meters of impact glue of chip board floor which was holding down carpet tiles in a studio . took two guys a week and a half . we tried different chemicals and we found white spirit had to be put down first 3 sq meters at a time then scrape it of with an angle head razor scraper 18 inches long(rigid body with blade at angle ) .be changed blades at about every 50 meters sq . the glue acme up like a snake skin and we ended up with plastic sacks filled with jelly like waste . our floors had to be painted so we had to get rid of every trace of glue. its a on your knees job and be careful with that blade ! patience ,determination and the right kit is the key .

Debra on February 21, 2012:

I am removing rug (indoor/outdoor)from a family room. Underneath is some old blue sponge backing that has now aged, and in some cases harded to the plywood. Any tips on how to remove? It was put in in 1973.

sherry on February 11, 2012:

What kind of paint can I use to paint over left over black mastic left on a concrete floor. What kind of paint will bond to the mastic?

James on February 11, 2012:

Great post- using this method now to get layers of paint and adhesive off old stair treads

Work fine with hot water.


Linda on January 22, 2012:

Well I have the glue marks on the sticky tiles from a rug I put in the bathroom at Christmas. I'm going to the hot water and a scraper....hope it works. Some told me to use nail polish remover, but that didn't help.

Patrick and Marissa on December 04, 2011:

Thank you so mucch for that information and tip. That was a total time saver. Thank you tha

nk you thank you thank you!!! We had to remove the carpeting in the mens restroom at the gym we work at and it was a pain in the neck to figure out how to remove the adhesive.

fairleys4 on November 16, 2011:

I am trying to remove old glue from those sticky squares in my bathroom floor. My husband has used several types of adhesive remover and also scrapped as much as possible. You can still see the "score" lines where each square was. I am trying to get this removed so that we can stain the concrete. We were thinking our next step would be to rent a professional sander. It is a small area measures 74 in X 94 in. We are thinking of redoing all of our down stairs floors with the concrete stain. I don't think the rest will be nearly as bad as this bathroom as far as this adhesive goes. I have not tried the hot water yet. Any other sugestions?

Jean on November 10, 2011:

I LOVE google!!

I have cats and my 16 year old male started using my carpeted dining room as his favorite litter box. I couldn't take it any more and pulled up the carpet and have decided to do something artsy with my cement floor. The yellow glue around the room perimeter has been holding me back. I got out my sander with coarse sandpaper but it did nothing to get the glue up.

I am going to try the hot water method! Much cheaper and green than using acetone and acids to try to get it off. This site has been great - and very entertaining, I must say!!!


Joan on October 12, 2011:

We are in the process of removing glued down carpet from the cement basement floor. Only about 3/4 done taking carpet up and I'm exhausted. We had no idea how to remove the backing and glue so I checked this site. I am PRAYING that the hot water method will work. It is such a large area...let you know how it all works out. Wish us luck!

FLAGOLFER on October 07, 2011:

Thank you, thank you, thank you! I just took up outdoor carpeting from my lanaithis morning and the dreaded yellow glue is left behind. At least I was smart enough to try online first before going to buy anything to get it up. I find your post first so tomorrow morning I will try the hot water and the scraper. Thank you very much!

You have saved my alot of money and wasted time.

Nina on October 07, 2011:

I just took of a carpet from my 200 sq/ft balcony and realized that the conceret floor was painted before the previous ower used the yellow glue to instal the carpet. Anyone know how to take the glue off a painted conceret floor? I will try the hot water method on the weekend, but don't know if it's going to work.

Matty on October 04, 2011:

Razor blade scraper, easy but tedious gets the job done, pressure washing is another solution

Syble Dees 9-26-2011 on September 26, 2011:

I tried the boiling water and it works,thanks it saved a lot of work.

rosie on September 20, 2011:

Use ammonia the glue comes up quick

Esra' on August 28, 2011:

I will try this and hope for the best because the yellow glue on my tile floor has been there for years and I hope it wouldn't harm the or scratch the tile it self...thank you so much for the tip :))))))))

Elizabeth on August 20, 2011:

Try Genkem glue remover. Expensive but it works.

Verlie Burroughs from Canada on August 13, 2011:

I am still laughing (although it's not funny) after reading comments posted here on the dreaded yellow glue removal. The microwave solution had me falling off my chair! I just came here for advice on how to remove old carpet and found people with a much worse problem than I have. Keep up the good work folks, so glad the hot water & elbow grease method is working for you!

I am trying to remove smelly old desintigrating carpet from a mobile home (luckily it isn't glued down). Any tips on getting the edges of the carpet that are stuck in under the wall paneling?

And yes the underlay has turned to toxic dust. I'm using a mask, but wondering if that is sufficient protection? Don't want to die doing this job.

Also,I noticed there aren't many how-to sites for doing mobile home renovations. Maybe I'll try some searching here.

Thanks so much for this formum. I really needed a good laugh! Kinda dusty...

sammies on August 09, 2011:

So I'm posting again. I got all the glue off but it took me 3 weeks. I tried about 5 different solvents recommended to me and then found ZEP floor stripper in the cleaning product aisle at Home Depot. The instructions say to use 1 part water to 1 part solvent and let sit 30 minutes. I put that $^!t on pure. (made sure to have a high grade solvent mask on)I let it sit for 20 minutes and the glue started to lift quite easily. Scraped it up and repeated for leftover stubborn spots. The other solvents worked but took over 3 hours to break the glue down and didn't work so well on the first try. I tried hot water but it cooled down too quick and some parts of the floor were unresponsive. The ZEP stuff worked really well. It just took so long on such a large room (800sq/ft).

Hope everyone else gets their job done.

dr.jasim on July 28, 2011:

thank u vvvvvv miuch i will try it

Deanna on July 14, 2011:

I have also found that Watkins citrus tub & tile cleaner helps. I used my steamer and found it was really, really slow. I had some of this around and tested it on a spot- let sit for 10 minutes and it did a pretty good job of dissolving the glue. For a scraper, the best thing I found is an ice scraper for scraping ice off the sidewalks in the winter- made it sooo much easier on the hands and back to be able to stand upright!

Annie on July 08, 2011:

We removed the horrible rubber backed carpet from the basement of the house we just bought, but the awful musky smell is still there. We are running a new powerful dehumidifier and it leaked some water...yes yes yes the glue and residue rubber just melted off in the little puddle. Please tell me the horrible smell went away after you all removed the rubber and glue.

We had the house inspected twice, the basement walls are bone dry with no sign of mold anywhere, just the pungent disgusting musty odor that we are praying is from the carpet residue.

Tom T. on June 28, 2011:

I just finished "trying a scraper, $11.95) that fits into a reciprocating saw to remove the carpet mastic. I have been using power tools my whole life and was attempting to have the tool do the work when after 5 minutes the blade broke (not from improper use). I then went to the internet and found this site and the suggestion about the boiling water. I will try it tomorrow. One thing I am going to try, is to dam up about a 3 foot square area using rope caulking to contain the water. I will let everyone know how it works. Thanks again for the tip.

Clare on June 27, 2011:

Dry Ice blasting is also a suitable option as it embrittles the glue and uses no chemicals and the glue just fractures away

John and Robyn on June 25, 2011:

We recently installed an above ground pool and on the deck was old carpet- we wanted to remove and replace. We could not get it to come off and we tried using chemicals, no luck! I did a search and found your boiling water method- it peeled right off!!!! Thank you so much!!!!! You saved us days of pain and labor:).

Sharona on June 06, 2011:

I got the yellow glue blues...Before I go for the hotwater method,does anybody know of it will hurt the surface of linoleum? I found a beautiful floor under the nasty carpet in my 1955 sunroof.

tom d on May 25, 2011:

what about using a wallpaper steamer for removing old carpet mastic

Mandy87 on May 18, 2011:

Hot blow-dryer and a little sharp scraper

PDsports on May 12, 2011:

does anyone know if a floor scraper (the kind that looks like a flat hoe) will work as good as a smaller razor-blade type scraper? I'm hoping to avoid crawling across the floor of my workshop. I've got about 350 sq ft. Will try the hot water method tomorrow. thx!

sammies on May 10, 2011:

I just leased an 800sq/ft space for retail and pulled up the disgusting carpet to find a whole lot of yellow and orange glue very dry and seemingly melted to the concrete. I just rented a very large and expensive sanding machine with diamond etched scrapers from Home Depot and it didn't work at all. I'm hoping to try the hot water technique tomorrow. Thanks for all the posts on here. I'll post back to report my progress. DON"T rent expensive machine for this job!!

ConnieZ on April 21, 2011:

Some of the posts make it sound so easy. Oh, I tried the chemical from Home Depot and got nowhere fast. I tried hot water and it removed the gunk left behind by the chemical. A friend suggested WD40. That did a little. So I retried the hot water in another place and it worked a little bit. A bit like chipping finger nail polish off without remover. Gonna take a few weeks at this rate.

Nettyb on April 20, 2011:

Hello I have read the majority of the comments and i've tried most of the suggestions.The hot water worked the best but we still had to use a whole lot of elbow grease.Me and my 2 sons start making up stuff to use.We tried bleach laundry detergent,bleach and other stuff nothing really did most of the work.We still had to do a lot of scraping.See we have 3 big size rooms to do.So I had decided to try one more solution,the name of it is called STICKY STUFF REMOVER BY FULLER BRUSH COMPANY.I said to myself I know this isn't going to work either.So I sprayed a plate sized amount to an area we hadnt't applied any of the other stuff to.I waited 1minute OH MY GOODNESS it came up like butter.This stuff is so good.The glue came up so easily I did't have to do no scrubbing no hard scraping at all.I didn't have but a half a can left.I will order me some more cans.Some of you may not know about Fuller Brush but they have been around over 100 years and they have a 100% money back guarantee.If the stuff don't work for you just send it back.

moe on April 19, 2011:

thanks for the info, I'll try it and hopefully it works.

Lenny on April 17, 2011:

I've got 1,400 sq/ft of yellow glue that tried to kill me today. As far as I can tell, it's been on there for the past 10 years and it's in a very dry/arid environment. Tried the hot water and it didn't help all that much - a few thin spots seemed to peel off with scraping, but the thick stuff didn't budge.

Any recommendations on the strongest chemical i can lay down to dissolve the yellow devil without melting my face off? I was originally all for going the non-toxic hippie juice rout, but the stuff I picked up (forgot the brand/product) didn't do jack.

I like the ammonia idea because it's cheap and easy to get ahold of, but if there are any recommendations for something stronger, I'd love to hear it.

billie on April 12, 2011:

We have just purchased a home and the basement floor is cement with carpet and adhesive. We have considered taking the carpet up, but it is such a large room. Can we carpet over top of the old carpet? If so, how do we adhere the new carpet in place?

J.P. Geatz on March 30, 2011:

use a wallpaper steamer

Neeraj on March 24, 2011:

Benzene is best for removing any type of glue, organic dissolves in organic....

Howard on March 14, 2011:

i pored hot water on the glue and let it sit 10 min

then sucked it up with shop vac then did it again and again and then sucked it up with shop[ vac when it was dry it pealed right up like magic hot water very hot water does this trick. it wasn't till it was drier that it came up but you will have to work at it some i got thru it and you will to good luck Howwy

howard on March 14, 2011:

how sweet it is thankyou ask.com

you make my life hole .

Momma on March 06, 2011:

One more added comment. Thanks to a neighbor stopping by, he went and got his "Heat gun." Never knew that type of thing existed. Worked like butter. My recomndation is to go with a heat gun and a small chisel. It works!

Momma on March 06, 2011:

Just wanted to say "Thank you, thank you" for this blog. I was on my way to purchase a grinder to remove the glue under my indoor/outdoor carpet, when I decided to give it one more try, and found your suggestions on the internet. The hot water did the trick! Just to tweek it abit, I took a hand towel, and got it good and wet, put it in the mircrowave for 2 minutes, put it on a plate and took it into the room I was working on, slapped it on top of the glue, sat back for 15 min. and bam it was soft enough to scrape up with a metal scraper. Now I have taken the microeave and put it in the same room with me so I do not have to walk as far. Works great for me. Any who, you saved me $, time,a sore back & hands, not to mentiom all the frustration envolved. Thanks again guys. You did good. One of your 66 yr. old fans, and a women at that! =) Now back to my microwave.

Veda on February 20, 2011:

I decided to flip the underlayment when faced with the prospect of trying to remove all that glue. That worked fine and I was able to paint the floor without going through all the torture of goo removal. I am planning to do it again in the room I'm reclaiming after my son moved out. It helps if the room is square. At least I think it does.

Linda on February 05, 2011:

Needed to remove the glue dropped by the carpet installer. RIGHT on the new carpet. They came out and cleaned, but all that came up was the dirt off the glue. We did not want to put anything on that would hurt the fibers, I tried this hot water on the carpet. Then scrubbed with a very soft rubber brush. It seems to have done the trick, but I will get back to you and let you know if it is works

Rob on January 31, 2011:

I spent three hours today trying to remove carpet from concrete with scraper and hammer...only was able to remove 1/8th of what needs to be done. Like everyone else my hands are now sore and blistered. Tomorrow I will try the hot water/hair dryer trick and hope it works.

Lydia on January 23, 2011:

I just finished cleaning off black foam pad maybe 1/2" thick that was all stuck like a blanket on my wood floor. I was ready to just recarpet since I had tried evrything. I tried the hot water and ammonia mix. dumped the mix in sections. Came back and was able to scrape it off fairly easy with hand scraper and long handled scraper and scotch brite pad, did 240sq ft 1day. (paid my son to help) thank you.

Taylor on January 10, 2011:

Would heating ammonia not be an option?

Erik on January 04, 2011:

Thank you, thank you, this totally works. Wire brush to get the crevices and a putty knife for the flat parts. Keeping the boiling water on the stove and doing a huge room with this method.

Ryan on December 15, 2010:

Ingenious. I've been working at a floor all day with cold water and a wire brush; I'm looking forward to trying this in the morning.

Thanks for putting in the time to share your knowledge.

c canning on December 05, 2010:

very easy use white spirit it softens the glue use a blade to scrape it off job done ive done this im a painter

Alissa on November 29, 2010:

You're right - hot water and scrubbing does the trick. But be warned: I also found that the water soaked through my wood flooring on the main floor and down through the basement ceiling. So one remodeling project became two. :)

km on November 11, 2010:

thanks a ton for the useful info. It worked and made the whole tedious job so easy!!!

sarah on November 05, 2010:

mean green and hot water...works great

darlene (CHICAGO) on November 04, 2010:


Melissa (Texas) on November 02, 2010:

Miracle of Miracles. After you try the hot water and it works, you just sit back and think, "Well, duh!!". I am glad I found this site. I had tried several different chemicals, combined with using a scraper. The last one worked, but I decided to do some research before spending more money on harsh chemicals. Soaking with water is working great to get up the paint and carpet glue on my concrete floor. It is not getting all the glue and it is still very labor intensive, but it is working just as good as the things I was buying. My plan is to stain the concrete floor in my house, so although the hot water does not clean up everything, it does save me money. Any ideas for removing the glue under my vinyl? I will try heat first, but I am trying to find ways to work smarter not harder, lol.

bigdrummer67 on November 01, 2010:

Thank you Maricarbo! What a wonderful solution. It has been a lifesafer.

Nanipoo on October 25, 2010:

I am SO glad I found this site. I tried some citrus based adhesive remover first but (1) it was expensive (2) if it got on anything it would start eating away at the paint. I tried the steamer method and, although slow, it was just what I needed. Can't beat the price too!

Ryan on September 26, 2010:

I am attempting to remove carpet from my porch, the carpet is laid/glued over plywood,spent all day stripping a small section. The porch is about 1000 sqft. Any suggestions, Not sure the hot water trick will work on plywood? I am grateful for any help.

Thanks, Ryan

Bob on September 11, 2010:

Great site. Excellent comments. Thank you so much for the practical info. Simple chemistry ...... can't beat it! I'm tackeling my yellow glue removal project this morning, so thought there had to be some info out there before I run to Lowe's. This is exactly what I needed to see. Thank you, thank you.

Douglas Robert on September 04, 2010:

Wow! You just saved me a ton of frustration. Thanks a million! I figured there had to be a way. Like you, I was just about to head out to the local Home Depot and see what chemicals were available to lift the glue. My wife suggested going on the web to see if a viable alternative existed.

Well, in one way today was my lucky day because I found your Hub page. Just spend the day removing stubborn 35-year-old glue... and it worked very well. Some areas required elbow grease, while other spots lifted without a problem.

Terrific solution -- thank you again!


Marky on August 30, 2010:

Thanks for the tips. I just pulled up carpet this weekend and there is a bunch of that adhesive. I'm going to try this sometime this week.

K on August 29, 2010:

I tried the hot water. this works great.

John on August 26, 2010:

I don't know how to thank you enough for this tip. I pulled up kitchen carpet that had been down for 20 years with the yellow glue underneith. I used a multi tool scarper and sander, which worked good, but I relized this was going to take a long time to get this gunk up, and it was not getting it all. I tried a small area with the hot water and a small scraper and it came right up. Thanks again, this works great.

Renee on August 20, 2010:

Wow, thanx mucho. Just used this tip, but for a cement terrace that my superintendant told me I wouldn't be able to take the gunk off it. Hot water + a scraper, yay! Did the trick pronto.

Kathy on August 20, 2010:

Thanks. I put kilz on a concrete floor before the last carpet was laid. Glue was put down to hold the pad. Since I ripped it out again the other day I tried sanding (doesn't work) then I used plain orange oil (bought in the lawn and garden section from lowes or home depot) and a scraper and it worked great. However, it is also removing the kilz. So I think I'll try the hot water and a long scraper. Looks like sears sells a good scraper.

Gale on August 19, 2010:

Thank you, I just ripped carpet off of my stairway and have been trying to get the glue off for days now. I've been sanding and discovered that didn't work and I was online looking for chemical strippers when I saw this. You will have my eternal gratitude if this works!

manbythesea on August 08, 2010:

My suggestion is simple and it works quite nicely. Use a hair dryer on high heat on the cemented rubber backing. Then while still warm, scrape the backing off with a scraper/putty knife. For the final unwilling pieces methyl hydrate and your putty knife will finish the job.

Doe_knob on August 04, 2010:

We had this same problem in a couple homes we lived in and could'nt figure out the best way to remove the adhiesive. We found a product by Jasco called Premium Paint and epoxy remover from Lowes or HDepot. This worked great its very thick just paint it on let it set for 30-40 min and scrape it off with a small hand held razor floor scraper then follow with soap and water, and sponge to wash the residue off. Make sure to ventilate the room and wear rubber gloves as it is a harsh chemical. A few spots we had to treat twice but this worked great. Just try on a small spot first to get the hang of it. The tougher the glue the longer you let it set but dont let it start to evaporate if so reapply.

I forgot to add that I am also using a wire brush (helps a bit with some muscle behind it). I will also be borrowing my neighbors power washer - not sure what the psi is (3500 is the strongest you can rent from HDepot)...

Project: black outdoor carpet on front cement porch.

I pulled it up and found the despised mastic glue. I started with a small orbital sander and 40 grit sandpaper (make sure you wear an Osha mask for dust, $5 at HDepot). I thought this was working until I poured on Krud Kutter adhesive remover (after reading a review on Amazon.com) and the buffed gray surface turned black… I figured I was dealing with Lots of black mastic glue…. I then tried lacquer thinner on a small spot and that didn’t help either… OMGoodness, the fumes – not worth the health risks either! The Krud Kutter really didn’t do much, so I went back to the internet and learned about Bean-e-doo mastic remover which is a “green” product. Now, I still thought that I was dealing with black mastic glue at this point so after watching the YouTube video about Bean-e-doo I thought the product was going to turn my glue into old engine oil right off the bat… After applying the Bean-e-doo (around 7pm) this is when I learned that it wasn’t black mastic glue, but more likely the black I was seeing was vinyl from the back of the very old carpet.. While working at the surface with a broom, the black started giving way to tan and I realized that I am dealing with the worse mastic of all: the dreaded tan mastic - ugh. I left the Bean-e-doo on overnight and this morning (12 hours later) I found the mastic to be more pliable, but I still needed to really muscle it with my broom to get it to budge (the razor scraper didn’t do a thing), but it is working and I recommend this product, along with patience. Thanks to finding this valuable hub page, I then boiled a pot of water and poured it on the steps – this really works! I still have my work cut out for me tonight and into the weekend, but I am well on my way to getting all the glue off… I will post before and after pics when I have them. Good luck everyone and thank you so much maricarbo!

I also found a company that will send samples (free?) of their removers, but since I am almost done I’m going to pass on ordering them. But wanted to share anyway: Mast-Away Mastic Removers, http://www.masticremover.com.

Our church basement floods all the time. We ripped up the carpet, but the floor is covered in glue. We were told that we'd have to put carpet back down. We don't want to because of the flooding issue. I'm going to try this. It'll save us a lot of money and flood clean-up will be easier. Thanks.

OMG u saved my life. my hand is swollen from using a scraper w/o any hot water. I will try it! TY for ur commical but useful input!!

Sandra on July 12, 2010:

OK, the ammonia worked. half water half ammonia, a steel scrubby pad and a ton of elbow grease, but the floor is back to new looking.

thanks so much for this site. it really helped a lot.

ANNE on July 07, 2010:

THANK YOU SO MUCH. THIS WAS THE MOST HELPFUL SITE ONLINE THAT i CAME TO! This worked with hot water..but now i have a "mud " mess on my cement. The floor looks so dirty.

I rececntly ripped up carpet in a kitchen of a hundred year old home to discover this nasty yellow glue. It is so old that it just won't budge with the hot water trick. I scraped, sanded, bleached with a scouring steel wool and still have some nasty spots that I can't get out. It's like it was absorbed by the beautiful tile underneath. they are the old rubber tiles that you have to wax and polish and I do want to save them. I plan on trying the ammonia trick. wish me luck guys. my arms and hands are so sore. may take a day off before I go back.

awsome! wow, it does work. back to the basics. no chemicals.

kakora on May 12, 2010:

I was really concerned about how to remove the glue as the location is near pool and did not want to use chemicals or sander. OMG!! just did this as a test--plain water did it. Tomorrow I remove the carpet and will start to work on the glue. I think the idea of covering with plastic will work well so the water can soak in and not dry out in the heat (SW FL).

So glad to come across this info--thanks!!

May I Just Say a Big THANK YOU to you and your neighbour form the uk, my ha put down a terrible foam backed carpet and i have been looking to get rid of it for the last 2 years but didn't have the heart to do it with all the missions that came with the job but this worked on my concrete floor in minutes!!! THANK YOU THANK YOU THANK YOU

Tina M on February 13, 2010:

It works!!! I didn't need a scrapper. I use put hot water (for sink) on floor and left it while i went to buy a scapper (15mins) and when i got back, the glue was soft by the time i returned. I just mopped the glue in a pile. Done Deal..thnks

I took the advice with the water--it worked! We had 1500 sq ft of concrete to clean and we were agonizing over the effort it would take us to get all the yellow glue up. We too bought the 4 in razor scrappers and they are just about the best purchase made. We did not have to use hot water--room temperature water worked just fine because we covered the wet glue with plastic so it would soak. When doing a job as big as ours, we found that spreading water evenly over the glue and placing some 4 mil thick plastic (the best purchase we made) 12 ft wide by 25 ft long over the surface and letting it set for about an hour, the glue came up with great ease. The time it took to get the soaked glue up, the second area was ready to scrape up. By soaking while scraping, we kept moving and were done in a day. Thank you for the tip on the water.

my glue is black or something is black underneath my carpet on top of this soon to be beautiful hardwood floor. what do i use to get black crap off?

Good luck, Jeannie. Just be careful with the ammonia if you decide to use it because it, too, has harmful fumes and it might make you faint! It is really strong. I feel for you...I remember when I scraped and scrubbed and tried everything under the sun.
