Exterior Polyurethane Architectural Moulding
Exterior polyurethane architectural mouldings engineered from high-density rigid polyurethane (150-220 kg/m³) transform building facades with timeless decorative details. Designed with wood-like mechanical toughness and high impact resistance, these exterior mouldings will not split, warp, or decay under severe frost or hail impact (-100 °C / +80 °C). Their closed-cell structural formulation guarantees water absorption below 1%, ensuring complete moisture protection against rain and dampness. Pre-primed with a factory white acrylic technical primer, Polure exterior mouldings require an elastic, UV-resistant exterior facade paint. Installation calls for clean substrate preparation, 45° miter jointing, continuous PU assembly adhesive, and mechanical screw fixing (silicone adhesive is strictly forbidden). Lightly sand with 180-220 grit paper prior to painting for ideal coating durability.
Frequently Asked Questions
Why is high-density polyurethane superior for exterior mouldings?
It provides high density (150-220 kg/m³), complete rot protection, water absorption under 1%, and zero thermal distortion.
What paint should be applied to exterior polyurethane mouldings?
Topcoat with an elastic, UV-resistant exterior facade paint system for maximum weather protection.
How is exterior polyurethane moulding installed?
Mount using a continuous bead of PU assembly adhesive along with mechanical screws. Silicone is strictly forbidden.
