How to Install Skirting on Curved Walls

Why Choose Polyurethane Skirting for Curved Walls?

Polyurethane skirting is the best choice for curved walls because it is:

• Highly flexible: Bends smoothly to tight radii without cracking.
• Lightweight: Easy to handle and install.
• Supplied in 5.1m lengths, reducing visible joins.

Tip: Polyurethane mouldings are also moisture resistant, making them ideal for humid areas or rooms prone to temperature changes. In contrast, MDF skirting is not moisture resistant and can warp, swell, or deteriorate when exposed to moisture, which is why polyurethane is the more reliable option for curved or high-moisture environments.

Can MDF Skirting Boards Bend Around Curved Walls?

MDF skirting can bend slightly, but not as tightly as polyurethane.

Here’s a quick guide to minimum bending radii:

For a smooth, durable finish that maintains its shape, flexible polyurethane skirting is the superior choice for both tight curves and long-term performance.

Intrim’s flexible polyurethane skirting, tested to bend to a 400mm radius and supplied in 5.1m lengths, creates a smooth, consistent finish on tight curves, staircases, and round feature walls with minimal joins. For a seamless result where curved and straight walls meet, make sure you order the flexible and standard skirtings at the same time.

Tools & Material Needed

You don’t need any specialised tools — just standard skirting installation materials:

• High-tack adhesive
• Finishing nails/brad nails
• Measuring tape
• Nail punch
• Paint or finishing materials

Tip: Pre-measure and dry-fit your skirting before fixing permanently to confirm your wall’s radius meets the recommended minimum.
