FAQs

Can I paint this capping board?

The board is designed to be maintenance-free and features a finished white surface, so painting is generally not recommended or necessary.

What tools do I need for installation?

You will need a measuring tape, a fine-toothed saw for cutting, and a strong grab adhesive.

Is this product suitable for outdoor use?

This board is designed for internal use to cover existing window sills.

How do I clean the boards?

Wipe with a soft cloth and a mild soapy solution. Avoid abrasive cleaning pads.

Can I cut this with a standard kitchen saw?

It is recommended to use a fine-toothed handsaw or a power saw with a plastic-cutting blade to ensure a clean edge.

Troubleshooting

Board does not sit flat on the existing sill

Check the existing sill for debris or uneven paint buildup and sand it down before applying the adhesive.

Adhesive not bonding well

Ensure both surfaces are completely dry and free of dust or grease before application.

Setup, Compatibility & Care

To install, measure the length of your window sill including any overhangs. Cut the board to size using a saw designed for plastics. Apply a high-strength grab adhesive to the back of the capping board, press it firmly onto the existing sill, and hold until the bond is secure. For care, avoid using abrasive sponges or harsh chemical cleaners which can scratch the white uPVC surface. Simply use a soft, damp cloth with a mild detergent to keep the boards looking new. Ensure the ends are capped or finished properly for a moisture-tight seal.
