SikaLatex® SBR

SBR based multipurpose polymer for waterproofing and repair

SikaLatex® SBR is a synthetic rubber emulsion which when added to cement slurry / cement mortar / concrete / grout provides good adhesion and water resistance. It comes in the form of a milky liquid. It is fully soluble in water and is to be added directly to the gauging water of slurry / mortar / concrete / grout.

  • Adhesion to most substrates (concrete, stone, brick, ferrous metals, glass, ceramic tiles)
  • Improves elasticity, flexibility and tensile strength of cement and reduces cracking in mortar and concrete
  • Economical, easy to use and non-toxic
  • Inhibits cracking, improves surface hardening, limits wear and dust production
  • Makes the mortar waterproof and reduces susceptibility to acids and greases, salt petre action, etc
  • Mortar with SikaLatex® SBR shows extremely good bonding to bases like concrete, stone, brick etc
  • Reduces viscosity of cement injection grout and improves bond of cured injected materials with substrates
  • SikaLatex® SBR can be diluted with water (1 : 4 – 6) depending on the type of application
  • Screed required with Sikacim® / Sika® Plastocrete Super to protect waterproofing layer
  • Standard coating system can be further reinforced by placing glass fibre reinforcement Sika® Fabric-50 in between first and the second coat

Usage

SikaLatex® SBR is a high quality emulsion that substantially increases the quality of cement slurry / cement mortar / concrete / cementitious grout.   The scope of application are as follows:  
  • As a bonding agent for uses in repair and plastering
  • Bonds rendering and coating layers
  • Bonding between successive concrete casts by incorporating SikaLatex® SBR into bonding mortar
  • For making polymer mortar for repairs
  • For waterproofing of roof slabs, sunken slabs, basements, retaining walls, water tanks, sunshades etc. in combination with cement
  • Ensures high wear resistance against erosion
  • Long life and watertight masonry jointing
  • Used as modifier in bonding mortar for tiles & panelling
  • Multipurpose admixture for cementitious injection grouting into cracks or porous concrete works
  • Treatment for leaching and saltpetre action

Application steps

MIXING

SikaLatex® SBR is to be added to cement / cement mortar / concrete / grout depending on the type of application as per the table above.
Mixing of diluted SikaLatex® SBR to cement mortar should preferably be done manually by volume as per the table. When a concrete-mixer is used, pour the mortar as soon as its consistency is cohesive. Do not run the mixer too long.
When a waterproofing slurry or bonding coat is to be prepared, cement is to be added in the polymer for getting consistent mixture.

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
