High Density Plinth
Polure high density plinths deliver impact-resistant base blocks, door frame footings, and structural-looking transitions for interior pilasters and exterior wall molding. Manufactured from high-density rigid polyurethane (150-220 kg/m³), this plinth block exhibits wood-like mechanical strength and will not dent or crack under foot traffic or cleaning equipment impact. Featuring closed-cell composition with under 1% water absorption, it resists moisture, rot, swelling, and mold growth in damp foyers, bathrooms, or exterior entry portals. Engineered to remain dimensionally stable in temperatures from -100 °C / +80 °C with B2 fire safety compliance, every plinth arrives factory-primed with a white technical acrylic primer. Installation requires level positioning, continuous polyurethane assembly adhesive on rear and base contact surfaces, and mechanical screw anchoring. Fill countersunk screw heads and joint gaps with acrylic or facade putty, sand smooth (180-220 grit), and finish with paint.
Frequently Asked Questions
What material is used in the Polure high density plinth?
The Polure high density plinth is manufactured from high-density rigid polyurethane (150-220 kg/m³), providing wood-like impact strength and a B2 fire rating.
Is a high density plinth resistant to moisture and cleaning water?
Yes, with water absorption below 1%, it will not swell, rot, or harbor mold in damp areas or during floor washing.
How is a high density plinth installed at the base of a door frame?
It is installed using continuous polyurethane assembly adhesive paired with countersunk mechanical screws. Silicone is forbidden.
What paint should be applied to a high density plinth?
Apply water-based or synthetic interior paints for indoor use; apply elastic, UV-resistant exterior topcoat paint for outdoor entryways.
