Classic Shelf Support
Polure classic shelf supports serve as decorative architectural corbels under wall shelves, mantels, and decorative ledges. Crafted from high-density rigid polyurethane (150-220 kg/m³), these brackets provide high mechanical strength and impact resistance without adding heavy load to the wall structure. Their closed-cell construction results in water absorption below 1%, ensuring immunity to moisture, swelling, mold, and insect attack. Supplied factory-primed with a white acrylic coating, each shelf support is ready for final painting. Mounting requires applying a continuous line of polyurethane assembly adhesive on rear and top contact edges, complemented by countersunk mechanical screws. After installation, fill screw holes and joints with facade acrylic filler, sand smooth using 180-220 grit sandpaper, and paint with two coats of topcoat paint.
