Exterior Wall Bracket
Polure exterior wall brackets combine classic architectural support aesthetics with weather-proof polymer engineering for exterior facades and sheltered porticos. Molded from high-density rigid polyurethane (150-220 kg/m³), these decorative corbel brackets offer timber-like impact resistance while remaining lightweight, preventing structural stress on building walls. Closed-cell polymer construction ensures water absorption stays below 1%, making the bracket immune to rot, swelling, cracking from freeze-thaw cycles, or insect damage outdoors. Operating flawlessly from -100 °C / +80 °C and rated Class B2 fire-retardant, the bracket is pre-coated with a white acrylic primer. Installation requires surface cleaning, applying continuous beads of polyurethane assembly adhesive on wall contact faces, anchoring into masonry or framing using countersunk mechanical screws, filling fastener holes with exterior facade putty, sanding smooth (180-220 grit), and finishing with elastic UV-resistant exterior paint.
Frequently Asked Questions
What density polyurethane is used for Polure exterior wall brackets?
Polure exterior wall brackets are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like mechanical toughness.
Are exterior wall brackets weather-resistant in freeze-thaw conditions?
Yes, with water absorption below 1%, closed-cell polyurethane will not absorb moisture, swell, crack from frost, or rot.
How are exterior wall brackets properly installed on facade walls?
Clean the wall, apply continuous polyurethane assembly adhesive on contact edges, anchor with mechanical screws, fill holes with exterior putty, sand (180-220 grit), and topcoat with UV-resistant paint.
Why is silicone forbidden when mounting exterior wall brackets?
Silicone adhesive lacks structural bonding power. Installation strictly requires polyurethane assembly adhesive combined with mechanical screw anchoring.
What paint should be applied to polyurethane exterior wall brackets outdoors?
After light sanding (180-220 grit), paint exterior brackets with high-quality elastic, UV-resistant exterior facade paint to prevent UV discoloration.
