EWI-301 Water Based Primer - 5L

EWI-301 Water Based Primer is deep penetrating primer used to prepare walls before installing external wall insulation or render-only systems. EWI-301 limits the absorptive capacity of substrates and also strengthen and stabilise dusty substrates. It helps to enhance adhesion external wall insulation, paints and render coats. EWI-301 can withstand adverse weather conditions. EWI-301 can be used on concrete, aerated concrete, walls made of bricks, blocks and structural clay tiles, plaster coats, gypsum panels and gypsum plasterboards.

• Ease of Application,
• Can be used on a variety of substrates,
• Waterproof,
• Frost-proof,
• Vapour-permeable,
• Increases the adhesion of paints and mortars,
• Facilitates the application of paints and mortars,
• Usage: approx. 50-300 ml/m2 depending on substrate structure and absorptive capacity.
  

• All substrates must be stable, even and clean.
• Remove all unstable (dull sounding) plaster from the substrate.
• All uneven surfaces should be levelled out using the EWI-260 Levelling Mortar.
• Mix the contents thoroughly before use.
• Do not dilute with water or any other product.
• Apply using a brush or roller.
• Each coat should take approximately 2-4 hours to dry. Highly absorptive substrates should be re-primed after about 4 hours.
• Paints, surface finish products or adhesives should be applied at least 24 hours after priming.
• Work must not be carried out during rain or snow, in strong winds and in direct sunlight without special protection to limit exposure to weather conditions.
• Recently rendered coats must be protected against rain, frost and over-rapid drying.

• European Technical Approval No. ETA-07/0192
