How to Paint Your Exterior Windowsills and Frames

Step 1: Lay Down Your Dust Sheet and Prep the Area

Begin by clearing the area of any unnecessary items and then lay down dust sheets to protect the surrounding area from paint splatters. Ensure all nearby objects and plants that can’t be removed are covered before you commence work.

Step 2: Remove Old Exterior Window Paint and Repair Damage

If there are signs that your house exterior needs repainting, it’s important to remove the old outside window paint first and tend to any damage if required for the best possible finish. Use a scraper to remove any peeling or flaking paint from the windowsills and frames. Inspect the surface for damage and fill any cracks or holes with a suitable exterior filler and allow the filler to dry completely.

Step 3: Sand Windowsills and Frames

Sand the windowsills and frames using medium-grit sandpaper to create a smooth surface. Finish with fine-grit sandpaper for a polished base then wipe down the surfaces with a clean cloth to remove any dust.

Step 4: Apply Masking Tape and Prime

Apply masking tape to the edges of the window glass and surrounding walls to ensure clean lines. Use a primer suitable for exterior surfaces to prepare the windowsills and frames for painting and allow the primer to dry as per the manufacturer’s instructions.

Step 5: Painting Window Frames Exterior

Choose the best paint for exterior window frames, ensuring it is weather-resistant. Apply the paint to the window frames, using a smaller brush for intricate areas. Application of the paint should be done in smooth, even strokes, allowing it to dry before applying a second coat if needed.

Step 6: Painting Windowsills Exterior

For painting outside windowsills, use a durable exterior paint that can withstand harsh weather conditions. Paint the windowsills with a slightly larger brush than what was used on the window frames, ensuring even coverage. Apply a second coat if necessary, after the first coat has dried.

Step 7: Remove Masking Tape and Clean Up

Carefully remove the masking tape before the paint fully dries to avoid peeling. Clean your brushes promptly to preserve them and quickly tend to any spills.
