Impermax 2K: Rapidcure Waterproof Membrane
This recently developed product presents an alternative waterproofing concept. Impermax 2K is a hot 50°C spray applied two component product Polythane resin, which when combined permits very rapid coating of large area substrates in a single application- 1x 25Kg/m², establishing a water proof membrane suitable for light traffic substrates.
Prime the substrate with Humidity Primer where required, Impermax 2K is applied by the use of a PUR hot spray 2 component system, used to warm the components separately to equal temperatures of 50°C plus, mixing component ratio: 1:1 at the point of the nozzle.

This waterproofing resin can be applied at a minimum thickness of 1.6mm, touch dry after only 15 seconds, able to with stand rain after 15 minutes and pedestrian traffic after only 1 hours cure time. With a complete fully cure time period of 48 hours.
Impermax 2K can be reinforced to become UV stable with an added top coat of Impertran, applied at 300g/m² available in any RAL colour.
Colodur and Anti-slip Quartz Sand can also be used in conjunction with Impermax 2K, providing a grip reinforced flooring surface.
Due to the extreme Rapid curability time of Impermax 2K it is highly important that the substrate has been accurately checked, to ensure 100% resistance and resin adhesive.
The following substrate checks must be performed;
- 1. Verify substrate resistance to 1.5n/mm²
- 2. Ensure substrate is sufficiently cleaned- free of contaminants, e.g. grease, oil. Dust etc
