Fixing plaster walls can be easily accomplished by do-it-yourselfers with a little practice. However, working with plaster of Paris can be difficult because it sets and dries quickly. When using plaster of Paris, it is important to have all tools and equipment ready beforehand and work quickly for a successful outcome.
Step 1: Clean the Area
Use a mild cleaning solution and a damp rag or brush to clean the area that needs repairing. The area should be free of dirt, grime, loose plaster, or paint.
Step 2: Mix the Plaster
Mix 1 lb. of plaster of Paris with 6 oz. of cool water in a large container until it forms a smooth paste. Thoroughly mix the paste, let it rest for a minute, and then mix again for another minute. Add water until you achieve the desired consistency. Only mix what you need because it dries quickly.
Step 3: Apply the Plaster
Moisten the area to be repaired with a damp sponge or cloth. Apply the plaster with a putty knife, filling the opening or crack. Smooth it flush with the wall surface. If the hole is more than ВЅ inch deep or wide, fill it half full of plaster. Let it dry for several hours, then mix more plaster as in Step 2 and fill the rest of the hole. Let it dry completely before moving on.
Step 4: Paint the Area
Once the plaster is completely dry, apply a high-quality, flat latex interior paint to the patched area with a paint brush. Wait for the paint to dry completely before decorating with wallpaper or additional paint.
