Sopro EPG 1522 – Epoxy Primer
Low-emission, unpigmented, two-component liquid epoxy resin. Applied as primer to stabilize friable mineral substrates and as adhesion promoter on smooth substrates, e.g. metal, mastic asphalt and existing coatings. Applied as primer prior to laying large-format tiles on calcium sulphate screeds.
Freshly applied primer is blinded with either Sopro QS 507 fine silica sand or Sopro QS 511 coarse silica sand, depending on subsequent coating.
Used to provide seal and barrier to capillary action in cementitious substrates, to fill cracks, to grout joints around channels and floor drains, and to produce capillary-breaking joints.
Resistant to water, seawater, wastewater/sewage, alkaline solutions, diluted acids, salt solutions, mineral oils, fuels and lubricants. Used to seal capillaries in damp cementitious substrates to speed up laying of parquet, PVC etc.
Coverage: As primer approx. 0.250 – 0.400 kg/m² per application; as skim coat approx. 0.400 – 0.600 kg/m²
FOR USE AS a primer before application of waterproof membranes with Sopro PU-FD 1570/1571 surface sealant. For stabilization and sealing of open-pored or “porous” mineral substrates. As base material for the preparation of capillary-sealing compounds. For sealing off calcium sulphate screeds and for installation of large-format tiles.
Also as an adhesion promoter for bonded mineral screeds that are likely to be subject to higher loads.
Cured primer is resistant to water, salts, salt solutions, alkalis and alkaline solutions, grease, oils as well as diluted mineral acids, e.g. hydrochloric or sulphuric acid. Short-term resistance is provided against solvents such as petrol, fuels, etc. Limited resistance is provided against concentrated mineral acids, and organic acids, e.g. formic acid, acetic acid, lactic acid, etc.
