Gaps and cracks should be filled with a suitable filler and sanded lightly to an even finish.
Step 4: Surface Preparation
Proper surface preparation is just as crucial as proper painting techniques. The great majority of paint failures are attributed to inadequate surface preparation.
1. It is essential that the surface to be painted is thoroughly clean and dry.
Removal of dirt, dust and grease: Clean surface with a cleaner such as household detergent and water or sugar soap (if greasy or heavily soiled) and rinse thoroughly.
Glossy surfaces: Sand glossy surfaces until dull with sandpaper to promote adhesion.
2. Be sure to repair any surface imperfections/damage.
Gaps and seams: Fill all cracks and seams with paintable acrylic gap sealer. Prime the area.
Holes: Fill all holes with patching compound and sand smooth. Prime the area.
3. Peeling Paint
Scrape or sand to completely remove any peeling paint. Feather sand to a smooth edge and remove dust. Prime the area.
