3 Simple Steps to Paint a Bay Window Seat

A bay window seat is a stylish and relaxing addition to any main room, and it often serves as a focal point. Once your new bay window seat is built and installed, you will need to paint and finish it both to match the rest of the room and to protect it from the natural elements. Moisture can build up more easily on the inside edges of bay windows, which can lead to mildew on both the window framing and bay window seat if prevention steps have not been taken. Follow the simple steps below when painting your bay window seat to keep such problems from happening.

Tools and Materials

  • Primer
  • Paint
  • Angled paint brush
  • Square paint brush
  • Small paint roller
  • Wisk broom
  • Dust pan
  • Sandpaper
  • Painter's tape
  • Cleaning rag

Step 1 -- Sand and Clean

Smooth the wood surface of your bay window seat with a medium to fine grit sandpaper to ensure a smooth coat of primer. Thoroughly cleaning off any sanding dust and debris from the surface of your bay window seat will prevent one of the most common causes of uneven, bubbling or pealing paint jobs. This is the part of this project that probably requires the most patience, but the end result is worth the preparation. Sweep up as much dust as possible with the wisk broom, and then wipe up any residue with a damp cleaning rag. Allow the wood to dry before applying primer.

Step 2 -- Prime Before Painting

Apply painter's tape to any wall seams and other areas you do not want painted around the bay window seat. Select a contractor grade wood primer that is designated moisture- and/or mildew resistant. These are available in major hardware and paint supply stores. It is not recommended to use a paint with the primer already mixed in for your bay window seat because these have been found to be less effective in completely sealing against moisture seepage from bay windows. Apply an even coat of primer to the seat and allow it at least 4 hours to dry.

Step 3 -- Apply Even Paint Coats

You will also need an interior contractor grade paint that matches or coordinates with the rest of the room colors and design. Use a small fine angled brush to paint around any seams on your bay window first. This is the part of painting that requires the most attention to detail, and it is easiest to get it out of the way first. Apply two coats, and allow the first to completely dry before applying the second one. Paint the rest of the bay window seat, taking care to load your paintbrush evenly so that you do not end up with paint drips.

If your bay window seat is large enough, you can use a small paint roller instead. Always apply the paint with the grain of the wood for a smooth finish; this is often horizontally with most bay window seats, though there are a few exceptions. Once your bay window seat is thoroughly dry, carefully peel off the painter's tape and touch up any small spots you may have missed.
