Painting Window Trim Techniques

How to Paint Window Trim

1. 1 Remove Window from Frame

   

   To paint double‑hung windows, remove them from their 1 frames if possible. Newer, spring‑mounted windows are released by pushing against the frame.

2. 2 Drill Holes + Insert Two 2" Nails

   

   Drill holes and insert two 2" nails into the legs of a wooden 2 step ladder. Mount the window easel‑style for easy painting. Or, lay the window flat on a bench or sawhorses. Do not paint the sides or bottom of the window sashes.

3. 3 Begin Painting Wood

   

   Using a tapered sash brush, begin by painting the wood next to the glass. Use the narrow edge of the brush, and overlap the paint onto the glass to create a weather seal.

4. 4 Remove Excess Paint

   

   With a putty knife wrapped in a clean cloth, remove excess paint from the glass. Rewrap the knife often so that you always wipe with clean fabric. Overlap paint from the sash onto the glass by 1⁄16".

5. 5 Paint Remaining Trim

   

   Paint all flat portions of the sashes, then the case moldings, sill, and apron. Use slow brush strokes, and avoid getting paint between the sash and the frame.

6. 6 Move Painted Windows Up + Down During Drying Period Optional

   

   If you must paint windows in place, move the painted windows up and down several times during the drying period to keep them from sticking. Use a putty knife to avoid touching the painted surfaces.
