Polyurethane Wall Corbel
Polure polyurethane wall corbels provide structural visual support and classical elegance to interior archways, shelves, and mantelpieces. Crafted from rigid high-density polyurethane (150-220 kg/m³), these corbels combine the sharp details of plaster with impact-resistant mechanical strength equivalent to hardwood. The closed-cell polymer structure maintains water absorption under 1%, preventing rot, swelling, warping, or mold growth in humid bathrooms, kitchens, and covered exterior porticos. Engineered to endure temperatures from -100 °C / +80 °C and rated Class B2 fire-retardant, the corbel maintains its crisp profile indefinitely. Pre-primed at the factory with a white acrylic coating, it accepts any topcoat effortlessly. Installation involves cleaning the mounting surface, applying continuous beads of polyurethane assembly adhesive on rear contact edges, fixing with mechanical countersunk screws, patching screw holes with acrylic putty, sanding smooth with 180-220 grit paper, and painting with two coats.
Frequently Asked Questions
What density polyurethane is used for Polure wall corbels?
Polure polyurethane wall corbels are molded from high-density rigid polyurethane (150-220 kg/m³), providing timber-like toughness.
Can polyurethane wall corbels be installed in humid locations?
Yes, with water absorption below 1%, closed-cell polyurethane will not rot, warp, or mold in humid bathrooms or kitchens.
How is a polyurethane wall corbel correctly installed?
Clean the surface, apply continuous polyurethane assembly adhesive, fix with mechanical screws, fill countersunk holes with acrylic putty, sand (180-220 grit), and paint.
Why is silicone adhesive prohibited when mounting polyurethane wall corbels?
Silicone adhesive lacks structural bonding power. Mounting must be performed using dedicated polyurethane assembly adhesive along with mechanical screws.
What paint system is recommended for polyurethane wall corbels?
Lightly sand the factory white acrylic primer with 180-220 grit paper, then apply two coats of water-based or synthetic paint.
