LJS Concrete Adhesive

Liquid add mixture to strengthen concrete.


LJS CONCRETE ADDITIVE is an aqueous inorganic polymer designed to improve the strength and reduce the pore structure in the concrete to aid its waterproofing ability.

Benefits

  • Excellent workability
  • Creates waterproof concrete  
  • Minimizes segregation  
  • Has positive effect on all physical properties  
  • Reduces dusting on concrete 
  • Bleed water is reduced which allows better finishing  
  • Reduces the need to add water to mixes 
  • Reduces hardening shrinkage 

Application

LJS Concrete Additive should be mixed mechanically until it has a uniform consistency. LJS Concrete Additive is used as a liquid additive in LJS Waterproof Coating System. Add 16 oz per 50 lb. bag mix and 5.5 quarts of water. For waterproof concrete add to truck. When applied it will waterproof and densify concrete. Once added to the truck, the barrel of the truck should be mixed for five minutes at a slow mixing speed. You should ask for the concrete to come to site with 5% less water than normal. Than add water if needed. Vibration of walls is recommended to ensure a proper flow of product and concrete.
