Description

Description

Fast-setting, all-in-one grout for replacing sanded or unsanded grout. Formulated with DropEffect Technology to reduce surface absorption and help repel water and dirt, this efflorescence-free, polymer-modified grout offers consistent color, low shrinkage, and excellent stain resistance. Incorporating MAPEI's Hyperhydration Cement Technology (HCT), it eliminates common problems with Portland cement-based grouts (uneven color, efflorescence) and exhibits reduced absorbency compared to standard cement grouts.

  • Fine aggregate (FA) allows for tight joints and improved cleanability
  • Efflorescence-free (Portland cement-free)
  • Easy to install, stain-resistant, and requires no sealer
  • Reduces surface absorption to better repel water and dirt (DropEffect Technology)
  • HCT formulation for improved color uniformity and durability
