REMOVING FLAKING PAINT
If a painted surface is in poor condition and the paint is flaking, you will have to strip it off before repainting. Use a wide scraper to remove the paint. If the paint is stubborn, apply a chemical stripper. When the surface is bare, smooth it with medium-grain sandpaper wrapped around a cork block, lithe surface has been painted with tempera; seal it with a stabilizing solution after you have sanded it down.
HOW TO FILL HOLES
It is worth filling even small cracks and holes for a professional result. You can buy filler as ready-mixed paste or as a powder that must be mixed before use. Always check manufacturers’ instructions before preparing the paste. The average drying time is 30 minutes. Fill large holes with several layers of filler if necessary. After filling, sand down the surface. Filler can be difficult to remove from equipment, so if you are mixing your own, line the container with a plastic bag to avoid a messy cleaning job afterward.
1. Stat by brushing away loose debris with a small decorating brush.
2. Wet the hole with a small, damp brush to ensure that the filler stays inside the hole.
3. Press the filler into hole with a putty knife. Allow filler to dry between layers. Wipe off excess.
4. Smooth with the wet blade of a putty knife. Once dry, sand with fine-grain sandpaper.
