Block Joining Adhesive

 Block Joining AdhesiveFeaturesHigh Bond StrengthSpecial polymers imparts high adhesive strength (3.4Mpa) increasing overall masonry strength & load bearing capacity.No Shrinkage CracksWater is retained in mortar, thus preventsshrinkage cracks.High Thermal InsulationThin joints prevent head transfer through material walls.Zero WastageIt is easy to apply and avoids wastage of materialNo Curing RequiredDue to water retention polymers, curing is not essential after application.High coverage Due to lower density & higher volume, a 40 kgs bag of adhesive covers 200-225 sq. ft. with a thickness 3mm (for 4" thick AAC blocks).EconomicalQuantity of adhesive required for laying Premixed blocks is 3 times less than conventional a mortar.This saves money as well as time.PremixedNo jobsite blending of powder is required,only water is to be added.                                                                           ComparisonBlock Joining Adhesive                                                                    Conventional Mortar                                                                                              Cement (0.5 Kg.@ 300 Rs.
