An inexpensive way to rejuvenate walls and ceilings with minor blemishes is by applying a textured finish. Their rough surfaces of swirled plaster, grainy paint, and the like adequately cover old patches, chipped paint, and other irregularities.
The drawback of textured surfaces are challenging to apply by brush (but can be sprayed or rolled on), they are rough to the touch, and they are hard to clean. Heavy, sprayed-on textured finishes are also difficult to repair or cover later. For these reasons, they applied to ceilings but not walls.
Professionals often spray on rough finishes or use a roller which is the easiest way to apply the product for a novice. Textured paint comes in both latex and alkyd varieties. The latex type work over the wallboard because it covers seams and goes on without a primer.
Experienced contractors can save money using textured coating rather than preparing smooth ceilings and then applying paint. Here is how textured coating compares price to patching and painting a 10 x 12 -ft room that would need several hours of patching work if it were to paint.
Patch and Paint
Scrape ceiling $45.00
Patch cracks and feather edges $105.00
Apply two coats of flat latex paint for $80.00
Scrape ceiling of loose material $30.00
Spray ceiling with perlite containing coating $75.00
Prices, of course, may be different in your area, but they probably will stay in the same relationship.
The example shows that because plaster patching and painting are avoided with s textured, spray-on coating, using a textured surface is far cheaper than using a smooth one. In addition, the textured coating can have a soundproof effect in a room, much like acoustical tiles. However, that example also shows patching is needed if you are doing the work Spraying on the ceiling will be more expensive, and keep in mind job is limited to a single room rather than a whole floor or house. The contractor will charge more, and the fixed cost of setup and cleanup will be the same for one room or ten.
