How Do You Fit An MDF Window Sill?

  1. Measure The Sill:

Measure the width of the window sill above which you want to install it. Using a level helps you get an accurate measurement without having to add any angles.

  1. Attach MDF Sheets:

Place a Masonite panel over a large piece of plywood for added strength. Use screws and a hammer to attach Masonite to plywood.

  1. Cut The MDF Sill:

Cut out the window sill from the MDF sheets using a table saw, circular saw, or jig saw. You will need your Masonite sheets, your location in mind (front or back, etc.), and some strong adhesive such as E-6000 or Gorilla Glue.

  1. Attach The MDF Sill:

Attach the MDF window sill to the window frame using a few screws and E-6000 or Gorilla glue.

  1. Stain The Window Sill:

Before staining, you may want to paint the window sill with a water-based wood finish, followed by several coats of paint or stain. This will help protect your wood from moisture damage, which can cause rot and decay over time.

  1. Install The Glass:

If you’re adding glass to your windowsill, prepare for installation by allowing for a small clearance between the sill and glass as well as a gap between the side of glass and wood.

  1. Add Hardware:

If you’re adding hardware such as handles, you’ll want to add it to the wood window sill before finishing it. This way you won’t accidentally scratch or damage your finished project.

  1. Attach The Window Sill:

Attach the window sill above a window with screws and adhesive such as E-6000 or Gorilla glue. Keep the bottom of the sill at least six inches away from a wall for drainage.

  1. Add Waterproofing:

To prevent moisture damage, use a water-repellent sealant on your wood to create a waterproof layer between wood and air outdoors. You can purchase waterproofing from most hardware stores, paint or home improvement stores, or online.

  1. Clean The Surface:

Keep your wood window sill clean and dust-free so that it ends up looking like new. You can use a damp cloth to wipe the dirt away and dry the windowsill completely with a hairdryer or by using a hair dryer on low heat. Remove any debris that has fallen into cracks or crevices in the wood.

This will help prevent rot and decay. Use fine-grit sandpaper to smooth out any rough spots and scratches that may occur after staining the window sill.
