Satin paint has more gloss than flat or eggshell finish paint and less than gloss paint. This gloss causes adhesion failure of some paints. Surface preparation is essential for a good finish.
Clear the room
Move all the furnishings that are practical to remove from the room. Remove any decorations, art or photographs from the walls. Remove electrical outlet and switch covers.
Clean the walls
Put on gloves and use a solution of trisodium phosphate to wash the walls. This cleaner is very strong, but it is effective at removing grease from the walls and the gloss from paint.
Make necessary repairs
If there are holes, dents or cracks, repair them before you paint. Use caulk to repair small cracks. Repair nail holes and small dents with spackling compound. Larger holes sometimes require replacing wallboard.
Prime any repairs before applying the top coat. If you have sanded surfaces and removed paint to the wallboard texture, prime those spots as well.
Paint the room using the selected paint. If you are using a roller, apply the paint in the shape of an M to ensure even coverage. Allow the first coat to dry according to the directions on the can before applying any subsequent coats.
