RESIBLOCK SUPERIOR wet-look paving sealant is a urethane based low viscosity prepolymer in Hydrocarbon solvents. Its function is to bond the jointing sand and seal the surface of concrete block paving. Its penetration comes about by solvent evaporation, and polymerisation is created by the atmospheric and residual moisture effecting the cure. The resulting effect is an in-situ bond and stabilisation of the pavement that retains its normal flexural properties. RESIBLOCK SUPERIOR paving sealant is manufactured under the jurisdiction of ISO 9001/2.
