EIFS - Coarse Topcoat Skim
EIFS Coarse Topcoat Skim is a polymer and silicate modified, mineral based, skim coat. The product is specifically designed for use as the final levelling coat
over Astec EIFS Impact treated foam panels after their
on site installation in wall and fencing systems which
can be over coated with acrylic textures and coatings combining to provide strong inter-coat adhesion.
The product is modified with very high levels of
flexible polymers and hydrophobic agents that ensure
a well adhered render with excellent resistance to
water, efflorescence or rising damp. The cured product
is waterproof, hard but flexible and provides greater adhesion to the Impact treated foam than the
cohesive strength of the foam itself.
The product is supplied in a 20 kg paper sack. On site mixing requires only the addition of fresh clean water
to achieve a smooth workable paste at a desired consistency. No additional polymer additives are
required and should not be added.

Suitable Substrates:
Astec EIFS Impact coated polystyrene.
