The National Skirting Bullnose Primed Window Board is an ideal solution for homeowners and professional contractors looking for a durable, aesthetically pleasing finish for window sills. It offers the timeless look of wood with the modern performance of moisture-resistant MDF, providing a reliable surface that resists common timber defects like warping or knots. While it requires a final topcoat of paint to achieve the desired finish, its pre-primed surface significantly reduces preparation time during installation.

Yes, it is constructed from moisture-resistant MDF, making it an excellent choice for bathrooms, kitchens, and other humid areas.
No, this product is designed for interior use only and should not be exposed to direct weather or external elements.
No, the board comes pre-primed, though a light sanding is recommended to improve adhesion before your final paint coat.
Standard woodworking tools such as a handsaw, circular saw, or mitre saw are sufficient for cutting the MDF material.
Yes, high-strength construction adhesive is often used, but ensure the surface is clean and level before application for a secure hold.
Each board is 3040mm in length.
Use a fine-tooth saw blade and sand the cut edge lightly with medium-grit sandpaper before painting.
Lightly de-nib the pre-primed surface with fine-grade sandpaper and wipe away dust before applying the final topcoat.
Use a paintable decorators caulk to seal the joint between the board and the frame for a professional, flush finish.
To install, measure your window reveal and cut the board to length, allowing for any necessary protrusion. The board can be secured using a combination of high-strength construction adhesive and countersunk screws. Once fixed, fill any screw holes with a suitable wood filler before sanding lightly. After the board is primed and ready, apply two coats of your chosen paint, allowing adequate drying time between layers. For daily care, simply wipe the surface with a damp cloth; avoid abrasive cleaners to maintain the integrity of the paint finish.
