SikaLatex® R

SikaLatex® R

Acrylic latex bonding agent/admixture for portland-cement mortar/concrete

SikaLatex® R is an acrylic-polymer latex. It is not re-emulsifiable. It is a general purpose admixture which will produce polymer-modified concrete and mortar. Sika Latex R is also a bonding grout when mixed with sand and portland cement.

  • Concrete/Mortar/Grout/etc. containing SikaLatex® R exhibits improved adhesion to pre-pared substrates
  • Increased adhesive strength of mortar/concrete when used as a bonding grout
  • Increased resistance to freeze/thaw durability
  • Does not produce a vapor barrier

As mixing solution: for Concrete/Mortar/Grout/etc. use neat, replacing the amount of water typically recommended

As a bonding grout: estimated coverage based on amount of material (sand/cement) mixed
Application steps

MIXING

As admixture/mixing solution: With mixer running, add materials in the following order: SikaLatex® R solution and then the cement based product. Replace the amount of water recommended by the product. Do not dilute with water.
As a bonding grout: With the mixer running, add in the following order. SikaLatex® R solution, aggregate, cement. The ratio is 1 part cement, 2 parts sand, and a sufficient amount of undiluted SikaLatex® R to produce a creamy paint consistency. Maximum 4 gal./sack of cement (15L/sack of cement).
As a primer for acrylic coatings: No dilution is required. Use as is.
