Waterproof Trim
Polure waterproof trim offers seamless architectural edge protection and decorative border detailing for interior wet areas and exterior building facades. Molded from high-density rigid polyurethane (150-220 kg/m³), this versatile trim delivers wood-like mechanical toughness while remaining lightweight and resistant to impacts. Its closed-cell physical core maintains water absorption below 1%, guaranteeing that it will never swell, rot, or harbor mold in bathrooms, kitchens, or rain-exposed outdoor porticos. Fire-rated to B2 class and thermally stable from -100 °C / +80 °C, it arrives pre-coated with factory white acrylic primer. Installation requires clean, dry mounting surfaces. Apply a continuous bead of polyurethane assembly adhesive on contact faces; silicone sealant is strictly forbidden. Mechanical screw fixing is required for permanent installation; countersink screw heads, fill with acrylic or facade putty, sand smooth with 180-220 grit paper, and finish with interior paints or elastic UV-resistant exterior paints.

What material is Polure waterproof trim made from?
It is molded from high-density rigid polyurethane (150-220 kg/m³), offering wood-like impact strength and B2 fire safety.
How does waterproof trim perform in wet areas?
Water absorption is under 1%, making it completely immune to swelling, rot, and mold in bathrooms, kitchens, and outdoor facades.
How is waterproof trim installed?
Use PU assembly adhesive and secure with screws (silicone is forbidden). Fill screw heads with putty, sand smooth, and paint.
Can waterproof trim be painted for outdoor use?
Yes. After light sanding (180-220 grit), apply elastic UV-resistant exterior paint to protect against sun fading.
