Chryso®Dry-Block Mortar (formerly Dry-Block® Mortar)

Chryso®Dry-Block Mortar Admixture, part of the Chryso®Dry-Block System, is formulated based on a patented technology. It is a liquid, integral water-repellent, bond-enhancing admixture for masonry mortar. Tests demonstrate that Chryso®Dry-Block Mortar Admixture increases the flexural bond of both Portland cement/Lime and Masonry cement mortars to CMUs.

The wicking property, the amount of water absorbed, of masonry mortar is dramatically reduced when Chryso®Dry-Block Mortar Admixture is added at its recommended dosage rate. Chryso®Dry-Block MortarAdmixture is a requirement for all Chryso®Dry-Block System projects and no substitutions shall be allowed.

As an integral admixture, Chryso®Dry-Block Mortar Admixture provides bond enhancement and water penetration resistance throughout the depth of the mortar joint. Chryso®Dry-Block Mortar Admixture’s water-repellent properties will prevent the moisture from wicking through the mortar joint into the building’s interior. Likewise, it will not be wicked back to the exterior carrying soluble salts that can cause efflorescence at the joints on the wall exterior.
