EWI-221 EPS Winter Insulation Adhesive - 25kg
EWI-221 EPS Winter Insulation Adhesive - 25kg can be used both within the reinforcement layer and for fixing EPS insulation boards to substrates much like EWI-220. The major difference is that this winter adhesive can be used even when the external temperature is very low – in fact, it allows the external wall insulation systems to be installed down to temperatures as low as 0 degrees.
The Winter Adhesive comes as 25kg dry mix. 6.3 litres of water need to be mixed with the winter adhesive to form the adhesive mortar. Once set firm and hard, it has excellent water and frost resistance and unsurpassed adhesive properties in colder weather. We suggest using a large bucket and adding the water prior to the winter adhesive. Once the winter adhesive has been added to the water, it needs to be mixed using a paddle mix until an even consistency mortar is produced. Once the winter adhesive has been mixed, leave the bucket for 5-10 minutes and then remix using the paddle mix. The adhesive is then ready for use.
EWI-221 EPS Winter Insulation Adhesive - 25kg is the ideal product for installing polystyrene insulation systems during cold weather. With its excellent frost-proofing capabilities, Winter Adhesive can even be used in temperatures down to 0°C.

The presence of microfibres in the winter adhesive means that it will still set in a timely fashion even at low temperatures. This means continuous workflow when conditions would normally prevent it. EWI-221 Winter Adhesive can be used for two purposes:
An adhesive used to fix expanded polystyrene (EPS) to a substrate.
EWI-221 EPS Winter Insulation Adhesive - 25kg is prepared in the same way regardless of whether it is being used as a basecoat adhesive or to fix the EPS insulation boards to the substrate. EWI-221 should not be used for fixing extruded polystyrene (XPS) and thermal insulation on bituminous substrates.
