Fastcoat Self Levelling Roof Waterproofing System

Manufacturer: Liquid Roofing Sytems Limited 

Materials: Polyurethane 

Fastcoat Self Levelling Roof Waterproofing Systems are built up by applying the following components on site:
• Fastcoat Self Levelling — a one-component, polyurethane, liquid-applied waterproofing membrane available in black, light grey (similar to RAL 7001), dark grey (similar to RAL 7011), dark red and tile red
• Fastcoat — a one-component, polyurethane, liquid-applied ‘Quick Cure’ variant of Fastcoat Self Levelling waterproofing membrane, available in black, light grey (similar to RAL 7001), dark grey (similar to RAL 7011), dark red and tile red, and with a typical curing time of 2.5 hours at 14°C >85% RH and 4 hours at 7°C >50% RH
• PUR Add — a catalyst for mixing into Fastcoat Self Leveling or Fastcoat to reduce the curing time. The catalyst must not be used at temperatures above 20˚C
• Geo tex — a 80 g∙m–2 polyester reinforcement fabric for embedding into Fastcoat Self Leveling or Fastcoat over existing cracks, at upstands and other changes of plane in the unreinforced system
• Humid Prime — a two-component primer for use on concrete surfaces where the moisture content of the concrete is greater than 4%
• Thixo Add — an additive mixed into Fastcoat Self Leveling or Fastcoat when used at upstands.
