Trim, Doors/Bare Wood/To Be Painted
- Surface Preparation:
- treat any mildew with a 3:1 water:household bleach mixture, leaving it on for 20 minutes and adding more as it dries; wear eye and skin protection; rinse thoroughly
- dull any glossy areas of wood ("mill glaze") by sanding with medium (#120) grit garnet paper; wear eye protection, dust mask and work gloves
- fill any gouges with wood filler; let dry and sand flush
- fill gaps with quality acrylic or siliconized acrylic caulk, and immediately smooth it flush; allow to dry over night and make a second application if needed; do not sand a caulk
- remove any dirt by scrubbing with detergent and water; rinse thoroughly; let dry out
- lightly sand the entire area to be painted with fine (#220) grit garnet paper, then dust off with clean rags
- Priming:
- priming is necessary to ensure adhesion, stain blocking and sheen or gloss uniformity
- prime all surfaces: use a stain blocking primer that is recommended for interior use; choose from:
- latex stain blocking primer: excellent for general use, good adhesion, blocks most stains, superior long term adhesion and flexibility; easiest to use and lowest odor
- alcohol-based (shellac based) stain blocking primer: maximum adhesion and stain blocking; moderate odor upon application, requires alcohol clean-up; quick drying; use with ample ventilation
- oil-based (alkyd): superior adhesion and stain blocking; high odor upon application; use with ample ventilation; use if oil-based paint is to be applied
- do not use PVA latex wall primer for this
- do not leave a primer unpainted
- Painting:
- use top-of-the-line interior latex or oil-based paint in flat, satin, semi-gloss or gloss finish, depending on appearance desired
- oil-based will provide greater hardness, but may yellow, and will be prone to crack with time
- satin, semigloss and gloss paints will resist dirt and handprints better than flat finish
