Prepping Your Window Frame or Door
The key to a any good paint job is prep work. This ensures the paint properly adheres to the surface. Make sure you follow these four easy steps for the best outcomes.
1) Thoroughly clean the window or door with sugar soap and cloth or sponge. Leave to dry.
2) Lightly sand with sandpaper, ensuring the windows are completely dry before starting.
3) Wipe off the sand particles with a fresh tack cloth.
4) Cut masking tape to fit around the edges of your frame to ensure the glass and wood do not get accidentally painted. This will help prevent the paint from sticking the window sash to the frame, which can cause problems with opening the window later.
