EWI-221 Winter Adhesive - 25kg bag

Bag coverage : 5.00m2
Weight: 25kg

EWI-221 is a winter adhesive that would allow you to work in temperatures as low as zero degrees. It is used to mount EPS boards on to external surfaces and also to fix the reinforcement layer on those boards. Once mixed with clean water it becomes a homogeneous grey adhesive putty. It has excellent water and frost resistance and unsurpassed adhesive properties in colder weather. EWI-221 can be used on a variety of surfaces, such as concrete, light-aggregate and cellular concrete, ceramic or silicate surfaces. This adhesive can be used on untreated, plastered, painted or on textured external surfaces.


Note: EWI-221 cannot be used to fix extruded polystyrene (XPS) and on bituminous substrates.

CHARACTERISTICS
  • Ease of Application,
  • Can be used on a variety of substrates,
  • Quick drying,
  • Contains microfibres for increased flexibility,
  • Highly breathable,
  • Water-resistant
  • Frost-resistant,
  • Excellent adhesion to substrates and EPS panels
APPLICATION
  • Remove all loose or peeling plaster coats.
  • Level out the cleaned substrate with levelling mortar EWI-260.
  • Wall surface, plastered or not, should be wire brushed and rinsed with hydrant water and allowed to dry. Highly absorptive and dusty substrates should be primed with EWI-301.
  • Add EWI-221 dry mixture slowly to a container with 6.3 litres of clean cool water. Mix with a slow-speed mechanical mixer to achieve a uniform, lump-free consistency. Allow to cure for about 5 minutes and then mix again thoroughly.
  • Hardened mortar should not be mixed with fresh material.
  • Apply a portion of the adhesive to the EPS panel and spread it with an appropriate trowel.
  • On flat substrates, apply the adhesive to the entirety of the insulation board using a notched trowel.
  • Put the panel on the substrate surface and press to make it flush.
  • When adding the reinforced mesh, before drying, the mesh needs to be embedded within the basecoat adhesive.
  • Work must not be carried during rain or snow, strong winds and in direct sunlight, without special shields to limit exposure to weather conditions.
  • The average drying time is 12-48 hours depending on weather conditions.
