68% cost saving using Expanding Polyurethane(PU ) Foam Spray Sealant to seal Tie rod holes .

  Stop seepage from External Walls, Bathroom, Kitchen, Terrace, Windows etc. . Problem: Leakage from External Walls of the building Observation : Rainwater ( Water leakage) entering inside house through walls. Analysis : Rain water coming in through external walls due to cracks developed on walls. These cracks are developed due to expansion/ contraction of civil structure and micro movements. Action Plan : Make v- groove and expand the cracks using grinder or manual tools. Clean the crackline/ groove, apply  Supex PU 25  sealant to cover the cracks completely, excess sealant to be tooled away. After curing ( drying of sealant, 2-3 hrs) paint the crack filled area. Supex PU 25 is a polyurethane sealant with exceptional elongation, gap filling and tensile strength properties. It is also used to seal expansion joints, bond building material.   Seepage from Walls adjacent to bathroom Observation : Wetness or dampness on external side of bathroom walls. Analysis...

Types of adhesive Adhesive, in India, is primarily  classified based on their curing mechanisms and chemistry. Adhesives classification based on curing mechanism Water based adhesives – cure ( dry ) when water evaporates  from the adhesive. Eg: Fevicol white glue used  for plywood bonding in interior furnitures Solvent based adhesives  – cure ( dry ) when solvent evaporates  from the adhesive. Eg-rubber adhesive used for type puncture  repair, shoe repair. Non curing adhesives  : Eg: butyl sealant for bonding car door fabric to metal body. Reactive adhesives – cures when it reacts due to some external factor( eg- UV curing glue) and chnages phase from liquid to solid. Eg: 2 part araldite cures after expocy and hardener are mixed together. Based  on chemistry Acrylic adhesives  – Generally 2 part adhesive system for structural bonding. Anaerobic adhesives  – one part adhesive used for threadlocking, threadsealing, flange sealing, bonding ...
