Aqueous polymer emulsion used to ensure proper adhesion of ISOFLEX, ISOFLEX AEGEAN and  ISOFLEX HYBRID elastomeric, liquid-applied waterproofing membranes for flat roofs to porous substrates. By penetrating the pores of the substrate, it acts as a bonding layer between the waterproofing membranes and the substrate. ISO-PRIMER is ready-to-use primer for ensuring the adhesion of ISOFLEX, ISOFLEX AEGEAN and ISOFLEX HYBRID to substrates like concrete, masonry, plaster, gypsum boards, chipboards, etc.

Substrate
The surface to be primed must be dry and free of dust, grease, dirt, etc.

Application
ISO-PRIMER is thoroughly stirred and applied uniformly to the substrate with a brush, roller or spray, before the application of the liquid-applied elastomeric waterproofing membranes.
