Classic Stair Baluster
Polure classic stair balusters bring traditional elegance and structural durability to interior staircase and railing assemblies. Crafted from high-density rigid polyurethane (150-220 kg/m³), these balusters replicate carved timber details while eliminating susceptibility to warping, splintering, or woodworm infestation. With closed-cell construction maintaining water absorption under 1%, they remain immune to dampness, rot, and seasonal swelling. Rated B2 for fire safety and stable across temperature extremes from -100 °C / +80 °C, each unit comes with a factory-applied white acrylic primer. Fasten balusters using continuous PU assembly adhesive on bottom and top mounting points, combined with mechanical countersunk screws. Fill fixing points and joints with acrylic putty, sand smooth with 180-220 grit, and finish with two coats of quality interior paint.
