With contoured or intricate trim or molding, use a sanding sponge rather than sand paper. The sponge gets places the paper can't reach.

Use a hand vacuum with a brush attachment to clean dust and debris off woodwork and doorframes.

With eggshell and semi-gloss finishes, every imperfection shows through. So proper prep is critical when painting woodwork. Fill in dents and rebuild chipped corners with wood filler. (Most woodwork is typically painted semi- or gloss.)

Use spackle on scratches and smaller cracks. Keep sanding and filling till you get it right—the end results are worth it. Finally sand the dry surface with 180 grit paper and wipe off all the dust.

Use a latex or oil-based primer formulated for stain blocking and sealing the surface.

There are three ways to prime a glossy surface:
1. Use a latex or oil-based primer formulated for glossy surface adhesion.
2. Use a liquid deglosser such as Prepaint, following all label instructions.
3. Go over the surface with 200 grit sandpaper. The scuffing will help the new paint adhere. Then wash the surface with TSP, rinse with water, and let dry.
