Architectural Corbel
Polure architectural corbels bring classical load-bearing visual expression and sculpted craftsmanship to interior arches, entablatures, and exterior roof overhangs. Engineered from high-density rigid polyurethane (150-220 kg/m³), these corbel elements deliver the mechanical strength of dense timber while remaining remarkably lightweight, preventing structural overloading. Closed-cell polymer architecture guarantees water absorption stays below 1%, shielding the corbel against rotting, swelling, or mold growth in humid environments or outdoor conditions. Thermally resilient from -100 °C / +80 °C and rated Class B2 fire-retardant, the corbel maintains its sharp acanthus leaves and scrollwork. Pre-primed at the factory with a white acrylic coating, it accepts topcoats effortlessly. Installation requires cleaning mounting surfaces, applying continuous beads of polyurethane assembly adhesive, anchoring with mechanical screws, filling fastener holes with acrylic or facade putty, sanding with 180-220 grit paper, and painting with two coats.
Frequently Asked Questions
What density material is used for Polure architectural corbels?
Polure architectural corbels are produced from high-density rigid polyurethane (150-220 kg/m³), providing wood-like mechanical toughness.
Can architectural corbels be installed in humid locations or outdoors?
Yes, with water absorption under 1%, closed-cell polyurethane will not rot, swell, or mold in humid rooms or exterior facades.
How is an architectural corbel correctly installed?
Clean the surface, apply continuous polyurethane assembly adhesive, fix with mechanical screws, fill countersunk holes with acrylic putty, sand with 180-220 grit, and topcoat.
Why is silicone adhesive forbidden when fitting an architectural corbel?
Silicone adhesive lacks structural bonding power. Installation strictly requires polyurethane assembly adhesive combined with mechanical screw anchoring.
What paint system should be used on an architectural corbel?
Lightly sand the factory white acrylic primer with 180-220 grit paper, then apply two coats of water-based, synthetic, or exterior UV paint.
