Setup, Compatibility & Care
Before installation, ensure the existing window board is clean, dry, and structurally sound. Measure the width of your current sill carefully to confirm the 175mm board will provide adequate coverage. Use a fine-tooth saw to cut the board to the desired length. For the best result, use a high-quality uPVC-compatible adhesive or high-tack construction sealant to bond the board to the existing sill. Apply pressure until set. Once installed, simply wipe the surface with a damp cloth and a mild non-abrasive detergent to maintain the bright white finish; avoid using harsh chemical solvents that could scratch or dull the plastic surface.
