+44 (0)1992 523523 Website

Application

For waterproofing concrete slabs, flat roofs, terraces or balconies, wet and damp rooms and similar applications. It has excellent adhesion to most substrates (including masonry, concrete, screed, Polyvinyl chloride (PVC), fibre-reinforced plastic (FRP), plastics, metal, and bitumen) and high elasticity.

Description

A single component, liquid applied, elastic, crack bridging waterproofing material based on MS Polymer technology. It is characterized by excellent adhesion to a wide variety of building materials and can be applied on dry or slightly moist substrates. It is liquid applied and therefore seamless, which greatly eases application to complicated architectural details. Due to its UV stability, it is suitable for internal and external use. It is quickly resistant to rain.


The fast curing coating is solvent free and does not contain isocyanates. It is highly flexible, resistant to occasional foot traffic, aging, hydrolysis, UV-rays, salts and frost. CE marked to BS EN 1504-2.


When applying over concrete, the substrate must first be primed with Köster Construction Resin or Köster LF-BM, which is then broadcast with kiln-dried silica sand to increase adhesion.
