Extended Product Information

FAQs

Can this be used on exterior window sills?

This product is designed for internal use only.

Do I need to remove my old window sill?

No, this product is specifically designed to cap over an existing sill, saving you from the mess of demolition.

Can I paint the board a different color?

While the finish is designed to be maintenance-free white, you should check with a paint manufacturer for specialized uPVC-bonding paints if you wish to change the color.

How do I cut the board?

The uPVC material can be cut easily using a fine-toothed handsaw or a power jigsaw with a plastic-cutting blade.

Are end caps included?

End caps are sold separately. It is recommended to purchase them to achieve a finished, professional edge.

What glue should I use?

A high-quality, quick-grab construction adhesive suitable for uPVC and wood/masonry is recommended for the best bond.

Troubleshooting

Board does not sit flush against the wall

Check for obstructions or unevenness in the existing sill. Use a sander or plane on the substrate to ensure a flat mounting surface.

Adhesive not gripping properly

Ensure the original sill surface is completely free of dust, grease, or peeling paint before applying adhesive.

Setup, Compatibility & Care

For a successful installation, ensure the existing sill is clean, dry, and free of loose debris. Use a fine-toothed saw to cut the board to the necessary length for your window recess. It is highly recommended to use a compatible end cap (sold separately) to cover the exposed cut ends for a polished look. Once installed, care is minimal: simply wipe the surface with a damp cloth and mild household detergent. Avoid using harsh abrasive cleaners or scouring pads, as these can scratch the uPVC finish.
