Moisture-Resistant Moulding
Assess water and moisture exposure using the product technical data, surface finish and installation details. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this molding features a completely non-porous closed-cell matrix with water absorption strictly under 1%. Unlike wood or MDF alternatives, it is highly resistant to rot, swelling, warping, and fungal and insect growth in bathrooms, kitchens, or spa areas. The profile exhibits wood-like impact resistance and dimensional stability has been tested between -20 °C and +70 °C, backed by a B2 fire safety class. Delivered with a technical factory white acrylic primer, it provides an optimal foundation for paint application. Installation mandates using a continuous line of PU assembly adhesive along all wall contacts and joining edges combined with countersunk mechanical screws. Fill screw points with facade filler, sand smooth with 180-220 grit paper, and paint with water-based topcoats.
