Description
Bostik HYTEC E570 ONE COAT is a two-part, solvent-free epoxy system containing the exact quantities of resin and hardener ready for mixing. Curing is by a stoichiometric chemical reaction, giving a gloss finish. It has been developed to suppress residual construction moisture in cementitious subfloors, including power floated concrete and sand/cement screeds. A single coat application on a smooth, power floated concrete base can protect up to a maximum hygrometer reading of 99% RH. It is compatible with calcium sulphate (anhydrite) screeds up to 90% RH (without UFH). Moisture readings quoted are based on BS 8203, using a properly calibrated and insulated surface hygrometer. It is suitable for warm water underfloor heating systems with cementitious screeds.
