Waterproof Ceiling Decoration
Polure waterproof ceiling decorations provide durable, high-relief ornamentation designed specifically for damp indoors and exposed exterior soffits. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these architectural elements deliver wood-like impact resistance without structural weight risks. A closed-cell molecular structure guarantees water absorption under 1%, permanently suppressing swelling, rotting, warping, or fungal growth in spa rooms, kitchens, and outdoor porches. Form-stable from -100 °C / +80 °C and rated Class B2 fire-retardant, the decorations retain crisp dimensional definition over decades. Each piece is pre-coated at the factory with a white acrylic primer. Installation entails preparing a clean dry substrate, applying a continuous bead of polyurethane assembly adhesive across all contact joints, anchoring with mechanical screws, filling fastener countersinks with acrylic filler, sanding smooth with 180-220 grit paper, and finishing with two coats of exterior or interior grade paint.
Frequently Asked Questions
What density material is used for Polure waterproof ceiling decorations?
Polure waterproof ceiling decorations are constructed from rigid high-density polyurethane (150-220 kg/m³), providing wood-equivalent structural firmness.
Why are polyurethane ceiling decorations completely waterproof?
The closed-cell polymer structure holds water absorption below 1%, preventing rot, swelling, or mold even in high-moisture settings.
How should waterproof ceiling decorations be 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.
Is silicone adhesive permitted for installing waterproof ceiling decorations?
No, silicone adhesive is forbidden due to lack of structural holding strength. Always use polyurethane assembly adhesive and screw fasteners.
What paint system is required for outdoor waterproof ceiling decorations?
For outdoor use, sand the factory white acrylic primer with 180-220 grit paper and apply an elastic, UV-resistant exterior paint system.
