EWI-220 EPS Basecoat - 25kg bag

EWI-220 Basecoat is  specially designed to fix fibreglass mesh reinforced layer for EPS thermal insulation systems. It can also be used for fixing EPS panels to substrates, such as such as concrete, light-aggregate and cellular concrete, ceramic or silicate surfaces. It can be used in fix EPS panels to interior surfaces. The polymer-modified binders in EWI-220 deliver strong adhesion, better flexibility, higher crack resistance and improved durability. It is highly durable, elastic, quick drying and has excellent frost resistance properties. 

Note: EWI-220 cannot be used to fix extruded polystyrene (XPS) and on bituminous substrates. 

• Ease of Application, 
• Can be used on a variety of substrates,
• Quick drying,
• Highly breathable,
• Water-resistant
• Frost-resistant,
• Excellent adhesion to substrates and EPS panels
  

• 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-220 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.

• European Technical Approval No. ETA-07/0192
