Baseboard is the trim that takes the most abuse in any interior. Vacuum cleaners bump it, shoes scuff it, furniture pushes against it, mops hit it, and pets scratch it. The material choice matters more here than in any other trim category.
High-density PU baseboard beats traditional wood for three reasons that show up within the first year of occupancy. First, it doesn't dent the way softwoods do. A chair pushed back into a pine baseboard leaves a mark; the same impact on a 250 kg/m³ PU baseboard leaves nothing visible. Second, it doesn't chip the way MDF does at the joints and corners. The closed-cell structure holds together under impact. Third, it doesn't move seasonally. A wood baseboard installed in January has a visible miter gap by August; a PU baseboard installed in any season looks the same in every season.
The cost calculation is more interesting than it looks. A solid hardwood baseboard in a standard profile is more expensive per linear meter than a comparable PU baseboard in a standard density. The labor cost is similar for both. The finishing cost favors PU because the pre-primed surface needs only one topcoat. Over a 30-room hotel project, the labor savings alone justify the material switch.
The aesthetic comparison is closer than the practical one. A stained wood baseboard has a warmth and grain that PU cannot replicate — if the design calls for visible wood, use wood. A painted baseboard is a different conversation; the PU version paints to a finish that is visually indistinguishable from painted poplar or painted MDF, and outperforms both in the places a baseboard gets hit.
Where the practical advantage becomes decisive is in wet areas. Bathrooms, kitchens, laundry rooms, basement stairwells — anywhere the baseboard is exposed to moisture or humidity. Wood baseboard swells, cups, and eventually rots. MDF baseboard puffs up at the base and loses paint. PU baseboard does none of these. A high-density PU baseboard in a master bathroom outlasts the tile.
For foreign-trade sourcing, high-density PU baseboard is a stock product at most factories, and the price per meter is competitive enough that it has become the default specification for commercial projects. The right conversation with the factory is about density (the spec should be 200+ kg/m³ for baseboard), profile availability, and lead time on the longer lengths (3-meter pieces are increasingly common and reduce the number of joints on long walls).

Frequently Asked Questions
Q: What is a PU skirting board?
A: A PU skirting board (also called a baseboard) is a polyurethane molding installed at the floor-to-wall transition. It protects walls from scuffs and vacuum damage while delivering a clean architectural edge. PU skirting is waterproof, impact-resistant, and far lighter than the equivalent timber profile.
Q: How do you install PU baseboards?
A: Cut PU baseboards with a fine-tooth miter saw. Apply construction adhesive in a continuous bead along the back, press to the wall, and tack with finish nails into studs where possible. Mitre joints at inside and outside corners, fill with spackle, sand, and apply two coats of paint. PU skirting requires no sanding of the face — it arrives primed.
Q: Can PU skirting be used in wet areas?
A: Yes. PU skirting is fully waterproof and ideal for bathrooms, kitchens, and basements. Use a polyurethane adhesive (not water-based) and seal the bottom edge to the floor with a thin bead of clear silicone in wet zones to prevent mop water from wicking under the profile.
Q: What height skirting board should I choose?
A: Standard residential skirting heights are 60–100 mm (2.4–4 inches). For modern interiors, taller profiles (120–150 mm / 5–6 inches) deliver a more contemporary look and visually raise the perceived ceiling height. Heritage and Victorian restorations typically use 150–200 mm (6–8 inches) with a stepped or ogee profile.
