Winter Adhesive EWI-221

Suitable for use both as the basecoat reinforcement layer and for fixing EPS boards onto the substrate, Winter Adhesive EWI-221 is specifically designed to be used in temperatures as low as zero degrees. This means that it is guaranteed to provide a waterproof, frost-proof and compact finish during setting and application times even in lower temperaturesNonetheless, Winter Adhesive can be used any time of year, allowing for maximum efficiency whatever the weather.

Intended Uses

Much like EPS Basecoat Adhesive EWI-220, Winter Adhesive has a dual purpose: it can be used both within the basecoat reinforcement layer and for fixing EPS insulation boards onto substrates. Winter Adhesive should not be used for fixing extruded polystyrene (XPS) and external insulation on bituminous substrates. Winter Adhesive comes as a dry mix, meaning it must be mixed with water before application onto substrates.

Application Conditions

  • Winter Adhesive should not be applied in rain or humid conditions, or if wet weather is expected before the adhesive has set.
  • While this adhesive is suitable for application in cold weather, it should not be applied if the materials or the substrate are frozen or if temperatures are lower than 0°C.
  • Use protective covers to shield the adhesive against extremes of weather conditions during and at least 8 hours after application.
  • EWI-221 should be mixed with approximately 5.3 litres of water per 25kg of dry mix.
