15th September 2025 How do I install skirting on curved walls? Install flexible polyurethane skirting boards with finishing nails and a high-tack adhesive, ensuring the wall’s curve matches the recommended bending radius. Intrim’s polyurethane skirting is supplied in 5.1m lengths and 18mm or 24mm thicknesses. It bends cleanly to a 400mm (18mm) or 500mm (24mm) radius. Pre-measure and dry-fit the moulding, then fix it in place with nails and a quality flexible adhesive for a professional, seamless finish. For a seamless result where curved and straight walls meet, make sure you order the flexible and standard skirtings at the same time.
