EPS Basecoat EWI-220

EPS Basecoat EWI-220 is suitable for use either for fixing EPS boards to substrates or for enhancing the reinforcement layer of an EPS insulation system. Containing reinforcing fibres, EPS Basecoat EWI-220 is a stronger substitute for EPS Adhesive EWI-210, allowing for maximum strength and stability of the EWI system. Its high-quality, dual-purpose nature enables installers to use fewer materials to complete their projects, offering maximum performance whilst limiting material wastage.

Intended Uses

The EPS Basecoat EWI-220 is a dual-purpose adhesive; it can be used both to fix EPS boards to the wall as a stronger substitute for the EPS Adhesive EWI-210, as well as within the reinforcement layer of an EPS insulation system.

Application Conditions

  • EPS Basecoat should not be applied in rain or humid conditions, or if wet weather is expected before the adhesive has set.
  • EPS Basecoat should be applied in temperate weather and should not be used in temperatures above 30°C. Likewise, if the materials or the substrate are frozen, or if there is any risk of frost damage within the first 24 hours, work should be postponed.
  • Setting time is typically between 24-48 hours, depending upon the environment and humidity.
  • EWI-220 should be mixed with approximately 5.8 litres of water per 25kg of dry mix.
