Starcoat Roof Waterproofing Systems

Manufacturer: Axter Limited 

Materials: Polyurethane 

Starcoat Roof Waterproofing Systems are built up by applying the following components on site:
• Starcoat — 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
• Starcoat QC — a one-component, polyurethane, liquid-applied ‘Quick Cure’ variant of Starcoat 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
• Starcoat PU Accelerant — a catalyst for mixing into Starcoat or Starcoat QC to reduce the curing time. The catalyst must not be used at temperatures above 20˚C
• Matcoat — a 80 g∙m–2 polyester reinforcement fabric for embedding into Starcoat or Starcoat QC over existing cracks, at upstands and other changes of plane in the unreinforced system
• Matcoat VV — a 150 g·m–2 glass-fibre reinforcement for embedment into Starcoat or Starcoat QC to achieve a fully reinforced system
• Primcoat Epoxy — a two-component primer for use on concrete surfaces where the moisture content of the concrete is greater than 4%
• Starcoat Thixo Additive — an additive mixed into Starcoat or Starcoat QC when used at upstands
