2. Repair Cracks and Chips

To repair cracks and chips, apply a thin layer of paintable caulk using a caulk gun. Use a small putty knife to smooth the caulk and remove any excess. Allow the caulk to dry completely before moving on to the next step.

3. Fill Gaps

For small gaps, use spackling paste or wood filler applied with a small putty knife. Press the filler into the gap and smooth it flush with the surface. Once dry, sand the area lightly until it’s flush with the surrounding molding.

4. Tighten Loose Joints

To tighten loose joints, carefully tap the molding back into place using a hammer and nail or a crown stapler. Use a small amount of joint compound if needed to fill any gaps or cracks. Smooth the joint with a small paintbrush and allow it to dry.

5. Sand and Paint

After repairing the damage, sand the area lightly with fine-grit sandpaper to remove any rough edges. Apply a coat of paint to match the existing molding and allow it to dry. Use multiple thin coats for best results.
