EPS Basecoat EWI-220 

The EPS Basecoat contains reinforcing fibres for extra strength and stability for EWI and render systems. It is also designed to be a dual-purpose adhesive. Firstly, it can be used to attach EPS boards to the wall, as a stronger substitute for the EWI-210 EPS adhesive. It can also be used within the mesh reinforcement layer of our EWI Pro EPS external wall insulation system.

Intended Uses

The 220 Basecoat is used to fix EPS to substrates and also as part of the basecoat layer. Once dry, the adhesive provides a strong, flexible and waterproof layer. Due to the fact that the EPS Basecoat has a dual purpose, it allows installers to have only one type of bag on site, therefore reducing any wasted materials.

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.
