Repairing small areas with American Clay
Small amounts of rehydrated plaster may be added to nicks, dings, annd nail holes and blended in with a trowel or sponge (depending upon compression technique used on the rest of the wall). In the video I only needed one layer of plaster for the repair; the steps below explain it in two layers. The size of the area you are repairing will determine if two layers are needed for the repair
1. Rehydrate plaster that was saved* for repairs and the wall you are repairing.
• 10% of total wall material should have been dried out and saved for repairs. If no material was saved, contact your applicator for material or contact American
Clay with color name and type of plaster used. If you do not know this
information, send American Clay a 2”x2” chip of the plaster. You can purchase
small 2 lb. or 5 lb. sample packages of plaster pre-mixed with color pigment from American Clay.
2. Apply a thin coat of base coat plaster and allow to dry. Reapply as many coats as needed to bring surface to 1/32” or below the finished surface. (Skip this step if surface has not exposed the first coat.) Let dry.
3. Apply second coat, leaving it “proud” (higher than surrounding wall).
4. Let patch dry.
5. Shave off excess using a sharp trowel, so that patch is level with the surrounding plaster. (If working with Marittimo, shave before totally dry, and shave in one direction).
6. Mist the damaged area with water and use a sponge or bondo tool to smooth the edges into the finished wall. Let this dry completely.
7. Re-mist and compress the patch and the surrounding area with the same technique used on the rest of the wall. Note: it is easy to over-polish (thus burnish) the edges of a patch. Work with a soft plastic trowel or bondo tool to avoid this.
