H790 is a two-component dispersion parquet adhesive which conforms to DIN 281. Immediately after mixing component A (Dispersion) and component B (Powder) a chemical reaction starts. This chemically binds more that 50% of the total water content within the product in approximately four hours. The ratio of free water in the adhesive is less than 11%. It is especially suitable for timbers sensitive to swelling and for low absorbent substrates.

Information

No solvents therefore no health & safety implications
Very low water content (11%)
Minimal swelling of the timber
High level of adhesion soon after application
Application: The two components must be thoroughly mixed using a drill fitted with a mixing blade. Mix until a uniform colour is achieved. Application should be made using a notched trowel of an appropriate size. Application should be made to an area no larger than that which can be laid within 10 minutes. The flooring should be laid onth eadhesive and pressed gently into the surface.
