Painting Exterior Windows

 
 

When it comes to painting the outside of your windows, look for a quality exterior trim paint. Trim paint is specially formulated to be tough and long-lasting. Prep work is a must. Wash everything down with TSP. Scrape off loose paint, and sand the rest. Prime bare wood. When you're painting, don't worry about getting some paint on the glass. Just wait until it's dry, then use a single-edge razor blade to scrape off the excess.

Step 1

Step 1: Scrape any loose window putty from around the edge of the window and brush the sash clean

Brush the wood you exposed with linseed oil to help the new putty stick. Roll some new putty into a noodle and press it into the bare spots. Pull a putty knife along it to create a flat sloping surface. Slide a damp finger along the putty in the other direction to remove any small imperfections.

Step 2: Let the putty dry for about a week

Then open the window and pull the top down until it’s about 3 inches from the sill. Push the bottom sash up until it's about 3 inches from the top of the window frame.

Step 3: Paint all the parts of the sash you can reach

Start with the pieces in the grid (called muntins) if there are any. Then paint the horizontal pieces, followed by the vertical. Following this pattern gives you a nice, neat job. Any brush strokes running across the grain are subsequently covered by strokes running with the grain.

  

Step 4

Step 4: Place sashes back in their regular positions, but don't close the window entirely

Leave about a 1-inch gap at the top and bottom. Paint the parts of the sash you were unable to reach in Step 2. Move the sashes as the paint dries to keep them from sticking.

Don’t paint the tracks the windows travel in—the paint buildup could cause the windows to jam.
