Decorative Frame Corners
Polure decorative frame corners are engineered to provide elegant right-angle transitions and ornate focal points for wall paneling frameworks, mirrors, and ceiling borders. Manufactured from high-density rigid polyurethane (150-220 kg/m³), these corners deliver timber-like mechanical durability while maintaining a lightweight profile that prevents structural strain on vertical surfaces. Featuring a closed-cell physical structure, water absorption remains under 1%, ensuring immunity against rotting, swelling, or mold growth in high-humidity areas like bathrooms and kitchens. Resistant to temperature shifts between -100 °C / +80 °C, the material achieves a B2 fire safety rating and comes factory pre-primed with a smooth white acrylic coat. Installation requires applying continuous polyurethane assembly adhesive along contact surfaces and securing with mechanical countersunk screws; silicone bonding is strictly prohibited. Joint seams and countersunk screw locations are filled with acrylic filler, sanded smooth with 180-220 grit paper, and finished with interior water-based or exterior elastic UV-resistant topcoats.
Frequently Asked Questions
What material is Polure decorative frame corners made from?
They are manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like mechanical strength, lightweight handling, and a B2 fire rating.
Are decorative frame corners moisture resistant?
Yes. With a closed-cell structure and water absorption below 1%, they will not warp, rot, or harbor mold in humid rooms.
How are Polure decorative frame corners installed?
Apply continuous PU assembly adhesive to contact backings and fix with countersunk screws. Silicone is forbidden. Fill screw holes and seams with acrylic putty and sand smooth.
Do frame corners require surface preparation before painting?
Yes, lightly sand the factory white acrylic primer with 180-220 grit sandpaper to remove mold release residue before applying topcoat paint.
