FAQs
What type of adhesive should I use for installation?
We recommend using a high-quality, all-weather silicone-based adhesive, a strong grab adhesive suitable for uPVC and building materials, or a dedicated uPVC solvent adhesive for best results.
Can this sill cover be painted?
While uPVC can technically be painted with specific uPVC paints, it's generally not recommended as the paint may chip or peel over time. The board is designed to be a durable, low-maintenance white finish.
How do I cut the board to size accurately?
For accurate cuts, use a fine-toothed saw, such as a uPVC saw or a jigsaw fitted with a suitable blade. A miter box can help achieve precise straight or angled cuts.
Is this product suitable for outdoor use?
While the material is 'exterior grade uPVC' meaning it's resistant to outdoor elements, this specific product is designed as an internal window sill cover board. For actual exterior window sills, dedicated external sill products are often used.
What tools will I need for installation?
You will generally need a tape measure, pencil, fine-toothed saw (or jigsaw), miter box (optional), adhesive gun, appropriate adhesive, and a soft cloth for cleanup. A spirit level may also be helpful.
Can I install this over an existing wooden window sill?
Yes, this sill cover is designed to be installed over existing internal sills, including wooden ones, provided the wooden sill is clean, dry, sound, and has a lip for the bullnose profile to wrap around.
How do I clean minor scuffs or marks from the surface?
For minor scuffs or marks, you can often use a soft cloth with a small amount of uPVC cleaner or a cream-based non-abrasive household cleaner. Always test in an inconspicuous area first.
Troubleshooting
Sill cover does not fit flush or leaves gaps.
Ensure the existing sill is clean and level. Re-measure and recut the cover board for precise dimensions. Use a suitable filler or sealant in any minor gaps after installation.
Adhesive is not holding the board securely.
Verify that both surfaces (existing sill and cover board) were clean, dry, and free of dust or grease before applying adhesive. Ensure you are using an appropriate strong adhesive designed for uPVC and building materials. Apply adequate pressure during initial curing.
Visible seams when joining multiple lengths.
For best results, use a specialist uPVC joint trim or miter the ends of the boards at a 45-degree angle for a cleaner, less noticeable join. Use a uPVC solvent adhesive for a strong bond at the joint.
Sill cover appears scratched or dull over time.
Avoid using abrasive cleaners or scouring pads. Use a soft cloth and mild soap or a dedicated uPVC restorer/polish to bring back shine. Prevent placing sharp or rough objects directly on the sill without protection.

Setup, Compatibility & Care
Setup Instructions
Preparation: Ensure your existing window sill is clean, dry, and free from loose debris or flaking paint. Fill any large gouges or uneven spots on the existing sill to create a relatively flat surface if necessary.
Measure: Carefully measure the length of your window sill. Account for any angles or returns if the sill wraps around the window frame.
Cut: Using a fine-toothed saw (like a uPVC saw or jigsaw with a suitable blade), accurately cut the Eurocell Sill Cover Board to your measured length. If angles are needed, use a miter box or protractor for precise cuts.
Dry Fit: Place the cut board over your existing sill to check for fit. Ensure the 'Bullnose' profile wraps snugly around the front lip.
Adhere: Apply a strong, all-weather adhesive (e.g., silicone-based or uPVC solvent adhesive) in a zigzag pattern to the top surface of your existing sill. Also apply a bead along the back edge of the cover board for a tight seal against the window frame.
Position: Carefully place the cover board onto the existing sill, pressing down firmly along its entire length. Apply even pressure to ensure good adhesion. Wipe away any excess adhesive immediately.
Secure (Optional): For added security, some installers may use small, countersunk screws at the ends or along the back edge, though adhesive is typically sufficient.
Seal: Once the adhesive has cured (check manufacturer's instructions), apply a thin bead of uPVC-compatible sealant along the joint where the cover board meets the window frame and any other exposed edges to prevent moisture ingress.
Compatibility
Designed primarily for internal window sills that have an existing lip for the 'Bullnose Hockey Nose' profile to wrap around.
Compatible with most common internal sill materials including wood, plaster, and older uPVC sills.
Verify the width (160mm) and thickness (9mm) against your existing sill to ensure adequate coverage and a flush fit.
Care & Maintenance
Cleaning: Wipe down regularly with a soft cloth and a mild, non-abrasive household cleaner or soapy water. Avoid harsh chemicals, scourers, or abrasive pads, which can scratch the uPVC surface.
Stain Removal: For stubborn marks, a specialist uPVC cleaner can be used, following the product's instructions.
Inspection: Periodically check the sealant around the edges, especially in wet areas, and re-apply if it shows signs of cracking or peeling to maintain moisture resistance.
