Materials Needed

Facet compound (for small cracks)
Sandpaper or sanding block
Caulking (waterproof)
Caulking gun
Putty knife
Paint (interior and/or exterior)
Paintbrush
Damp cloth or towel (for cleaning excess caulking)
Drop cloth (to protect surrounding surfaces)

Step-by-Step Process

Mix the facet compound thoroughly and use a putty knife to apply it around the window frame, focusing on small cracks or gaps.
Smooth it out for an even surface, as this will be sanded and painted later.
Allow the compound to dry fully before proceeding (typically a few hours, depending on the product).

2. Sand the Area

Once the compound is dry, use sandpaper or a sanding block to smooth out any rough edges.
Wipe away the dust with a damp cloth to ensure a clean surface for painting.

3. Add Caulking to Seal Edges

Use a caulking gun to apply waterproof caulk around the edges of the window, both inside and outside. Focus on areas where moisture could enter, such as corners or joints.
Smooth the caulking with a damp cloth or your finger for a clean finish. Remove any excess with a towel.

4. Paint Around the Window

Once the caulk is dry, use a small brush to paint the area around the window, including the section where the compound was applied.
Apply thin, even coats and allow each coat to dry before adding another. Two coats are typically recommended for a polished finish.

5. Final Cleanup

Clean up any leftover debris or paint splatters with a damp cloth.
Dispose of leftover compound and caulking properly.

Pro Tips

Work in dry weather: For outdoor caulking, choose a dry day to ensure the caulk adheres properly.
Use painter’s tape: If you’re worried about painting over the edges, use tape to protect the surrounding area.
Inspect your work: After sealing and painting, check for any missed spots or uneven areas and touch them up.
Choose quality materials: Waterproof caulking and good paint are key to long-lasting results.
