Eurocell Rounded Window Sill Cover Board Plastic Upvc Window Cill Capping - 1.25M Length - 210mm Width - 9mm Thickness - White

No, the Eurocell Rounded Window Sill Cover Board is specifically designed for internal use only. While it is made from exterior-grade uPVC, its primary function and installation method are intended for indoor window sills.

You should use a strong, uPVC-compatible adhesive or high-strength silicone sealant. These are typically available at hardware stores and are designed to bond plastics securely.

We recommend using a fine-toothed hand saw or a miter saw for clean, precise cuts. Always measure twice and cut once. For best results, support the board firmly during cutting.

This specific variant of the Eurocell cover board has a width of 210mm. If your existing sill is wider, this product may not fully cover it. You would need to check for other available Eurocell variants that offer greater widths.

Generally, uPVC is not recommended for painting without specialist primers, as standard paints may not adhere well or could flake over time. This particular variant is supplied in white, offering a clean, finished look without the need for painting.

Simply wipe the surface with a soft cloth dampened with mild soapy water. Avoid using abrasive cleaners, scouring pads, or harsh chemical solvents, as these can damage the uPVC finish.

Re-check your measurements against the existing sill's length and depth. If gaps are minor, a uPVC-compatible sealant can be applied carefully along the edges. Ensure the existing sill was clean and level before installation.

Use a fine-toothed hand saw for precision cuts on uPVC. Alternatively, a sharp utility knife with multiple passes along a straight edge can work for thinner material, but a saw is generally recommended for cleaner edges on 9mm thickness. Always support the board properly during cutting to prevent splintering.

Ensure you used a uPVC-compatible, strong grab adhesive and followed its application instructions. The existing sill surface must be clean, dry, and free of dust or grease. Apply sufficient pressure during installation and allow the recommended curing time before disturbing the board.
