Mosaic: Stepping Garden Stones


How To Mosaic Stepping Stones for a Garden

A wonderful easy lesson in making personalized stepping stones. Easy for even the beginner with a material list and lots of photos. This is the second of three tutorials on how to craft decorative stepping stones. The first tutorial detailed the steps of the "topper method", an easy quick way to make simple stones including "hand print" designs. This tutorial introduces you to the "glue n' grout method", a technique for crafting a more detailed stepping stone in four easy to follow steps. With this method you can create beautiful stones that can be used throughout your yard as eyecatching outdoor art.

Remember to check out Tutorial #1Make Stepping Stones the Easy Way and #3 Make Your Own Mosaic Stepping Stones for more stepping stone ideas and methods.

Making Stepping Stones Using a Mold

Part I

Step 1.Choose your mold.

There are numerous commercial stepping stone molds available in various sizes and shapes. If you are wanting to make a garden stone for decorative purposes only than a small mold (8") will be fine. If you are going to use it as a "stepping stone" than choose a 12" or larger mold.

Step 2. Set Up Your Work-Space.

Cement is very dusty and dried cement can be very difficult to remove from clothing and floors so choose a place (outside or a ventilated workspace such as your garage) to do your pouring. Lay down newspaper or plastic tarps on a level work table (an old shower curtain works great) . Make sure to set up your mold with all of your tools and water close by in easy reach.

Step 3. Preparing Your Mold

To keep the cement mortar from sticking to your mold lightly spray or wipe on vegetable oil. Depending on the size of your mold will determine how much cement and water you will use. To help determine your needs read below the section entitled "How Much Dry Cement Mortar Do I Use?"

Step 4. Mixing your cement mortar.

First, put on your dusk mask, gloves and safety glasses. Measure out your dry mortar into a large bucket. Add half of your measured water, saving the rest for adding as needed. Using a trowel, thoroughly mix the dry mortar with the water until it is like thick peanut butter. If the mix is too dry add a small amount of water until it is of the desired consistency. If is too runny add dry mortar. Make sure the slurry is thoroughly mixed before pouring. See mixing hints for additional instructions.

Step 5.Make it Smooth.

Scoop the mortar into your mold using your trowel. Using the back of your trowel spread the wet mortar evenly across the base stone and as level and smooth as possible. The total time you spend on mixing, pouring and smoothing should be no more than 5 minutes. Gently tap the sides of the filled mold with the handle of your screwdriver for at least 30 seconds to help burp the cement slurry of any air bubbles. This will also help level out the wet cement. Let it sit undisturbed overnight. Once the stone has hardened invert the mold and gently press on the back of the mold to release the stone.

Step 6. Drying Tips

Elevate the stone on wood dowels or pencils to maximize air circulation for even drying. For the first 24 hours after making your stone let it sit undisturbed. This is when it is the weakest. The following day you can move it indoors where it will need to fully cure for a couple more weeks before it can go outside.

Stepping Stones Mosaic

Glue 'n Grout Direct Method

Use this easy 4 part method to create a beautiful mosaic stepping stone.

This is a fun and a bit messy way to create gorgeous stepping stones. If you love playing with clay you will enjoy crafting stones with this method.

The first part will instruct you in how to make a base stepping stone that you will use to adhere your tesserae (the decorative items used to create the mosaic design). If you prefer, you can skip this step and instead purchase and use a commercial precast stepping stone, your choice of size, shape, and color.

The next three parts are easy to follow videos to teach you;

Part 2. How to adhere your tesserae (the decorative items used to create the mosaic design).

Part 3. How to apply grout the fun messy way.

Part 4. And our most loved step (I am joking) how to clean your stepping stone of all the excess grout.

How Much Water Do I Need?

The Rule of Thumb is for every cup of dry mortar you will need 2 ounces of water.

How Much Dry Cement Mortar Do I Use?

A Suggested Guide to Estimating Cement Amounts

Following is a list of available commercial mold sizes available for stepping stones with a suggested amount of cement mortar needed to fill each. This may vary from manufacturer to manufacturer. I have found some molds will state that they are say 12" in diameter but in reality they are only 11 1/2". If you want an exact size mold make sure you have a tape measure when you go to buy it!

Mold Size - Qty of Cement Mortar

8" Square - 7 cups

12" Square - 18 cups

16" Square - 25 cups

8" Round - 5 cups

12" Round - 12 cups

14" Round - 14 cups

18" Round - 25 cups

12" Hexagon - 10 cups

16" Hexagon - 24 cups

9" Heart - 7 cups

9" Butterfly - 8 cups

If you have a mold size that is not listed and you want to get an estimate for how much cement you will need do the following:

Fill your mold up with water to the level you would pour your stone. Measure the number of cups of water you used and multiply it by 1.25. This will give you an estimated amount of cement you will need. It is always better to make a little extra. If you don't have enough cement slurry to fill your mold you can always make up an additional batch and add it to your poured slurry. You have to make it immediately so as not to allow the first pour to set up.

For Your Information

A 10lb bag of Mortar has approximately 12 cups.

A 25lb bag of Mortar has approximately 30 cups.

A 60lb bag of Mortar has approximately 72 cups.

This is a very helpful lens. I live in an apartment, but if I had a yard, I would give this a try. I also like how you designed the lens itself. This is really thorough and with plenty of helpful hints.

Carolan Ross from St. Louis, MO on October 26, 2010:

SO glad to have found this, made some stepping stones once upon a time...fun but mostly by trial and error. Never knew the items one uses to decorate are called tesserae...like that word. At that time I had piles of old costume junk jewelry, fun tesserae. Made a heart-shaped stone as a wedding gift and 'engraved' their names and date with old beads. The butterfly shape is my favorite.

julieannbrady on October 19, 2010:

I love this crafty idea -- and will most likely be TRYING it myself real soon ... I will keep in touch!

MirandaBrooks LM on October 11, 2010:

This is such a good idea and sounds really fun! I think I will make one for my mom!

KimGiancaterino on October 06, 2010:

This is great. My stepson made me one of these and now we want to design a path for our garden. Thanks for the step-by-step instructions.
