Waterproof Exterior Ornament
Polure waterproof exterior ornaments are premium architectural accents built to withstand extreme outdoor weathering on building facades, gables, and entrance portals. Crafted from high-density rigid polyurethane (150-220 kg/m³), these exterior decorations deliver hail-resistant impact strength that outlasts conventional EPS foam or plaster. Closed-cell polyurethane restricts water absorption to less than 1%, rendering the ornament entirely immune to rot, mold, and freezing-thawing distortion between -100 °C / +80 °C. Arriving factory-primed with a durable white acrylic primer, they are ready for exterior finishing. Installation involves cleaning the substrate, cutting 45-degree joint miters with a fine saw, applying continuous PU assembly adhesive on back faces and joints, and fastening with screws. Joints and screw heads are puttied, sanded smooth (180-220 grit), and painted with UV-resistant facade paint.
Frequently Asked Questions
What density polyurethane is used in waterproof exterior ornaments?
They are molded from high-density rigid polyurethane (150-220 kg/m³), providing wood-like mechanical durability.
Will waterproof exterior ornaments rot or swell under rain?
No, closed-cell water absorption is under 1%, ensuring complete resistance to rot, swelling, and mold growth.
How are waterproof exterior ornaments mounted outdoors?
They require a dual mounting system of continuous PU assembly adhesive and mechanical screw anchoring.
Is exterior painting required for waterproof exterior ornaments?
Yes, while pre-primed in white acrylic, they must be painted with elastic UV-resistant exterior paint to prevent UV discoloration.
