K-88 ADMIX

K-88 ADMIX improves the curing of cement, mortar, and cementitious materials. Bonding agent promotes adhesion. Mix with Structural Skin, Conpro Stucco, Foundation Coat, Plastermix, and mortar.

  • Promotes curing Reduces need to moist cure materials in conditions up to 85°F. Reduces shrinkage induced cracking.
  • Increases bond Promotes chemical adhesion to substrate.
  • Durability Increases compressive and tensile strengths. Increases freeze/thaw resistance.
  • Water resistance Increases density and improves resistance to water entry.
Categories: ,

Surface Preparation

  • K-88 Admix is an admixture. Refer to the specific product bulletin for material to be used.

Priming

  • Follow the instructions of the material to which K-88 Admix will be added.

Mixing
