How to fit a window board
Fitting a window board is a straightforward process that enhances both functionality and style. Here are the basic steps:
1: Measure the window sill area accurately
2. Cut the window board to the required size, ensuring a snug fit.
3. Apply adhesive to the underside of the board for a secure bond
4. Press the board into place and use clamps if necessary while the adhesive sets.
5. Fill any gaps with caulk for a seamless finish.
6. Paint or seal the mdf window board or other materials as desired.
