Kemko® Grout IV

Hydrophobic Polyurethane Water Cut-Off Polymer


Kemko® Grout IV is a two-component, moisture-cured polymer that reacts with water to form a strong, rigid, closed cell foam of hydrophobic polyurethane. It is designed as a water cut-off and to fill large voids and cracks in stone or concrete. Kemko® Grout IV is used on interior concrete surfaces, to repair random cracks, control joints, and other areas where down time is limited. Kemko® Grout IV will discolor in exterior applications.
