Painting trim
Wash woodwork with a TSP solution and a plastic scrub pad to remove residue, and uses rubber gloves. Rinse several times. Remove blistered or chipped paint with a paint scrapper; be careful not to gouge the wood. Sand with 80-grit, then 220-grit sandpaper. Remove dust with a lint-free cloth after sanding.
Fill holes and gouges with a lightweight crack filler. Remove excess material material and let dry per the manufacturer's guidelines. Fill gaps and cracks between trim pieces with paintable caulk or glazing compound. Remove the excess and smooth with your finger.
Spot prime any knots or resin pockets with white-pigmented shellac primer. Allow to dry. Wipe the area with denatured alcohol or a paint deglosser. Mask all adjacent surfaces with blue painter's masking tape. Seal the edges firmly.
Prime the entire surface with a stain-blocking primer. After 24 hours, sand with a 220-grit sandpaper. Wipe the sanded surface with a damp sponge or cloth, then apply the finish with a 2-inch trim brush. Remove the masking tape while the paint is still wet.
