Tech-Dry® Salt Retarder is a water repellent admixture, providing rising damp treatment that inhibits the penetration of water and salts when added to cement/sand renders. It is an admixture which delivers three properties to the cement/sand render, which plasticises the render mix and provides water and salt resistance.
Using this rising damp treatment in sand and cement render mix eliminates the need for separate plasticisers and waterproof additives. Tech-Dry® Salt Retarder is recommended as a water repellent admixture for sand and cement render specifically after the installation of a silicone damp course to prevent residual salt and water migration.
It may also be used on a new wall to provide rising damp treatment and prevention on cement/sand render. Salt Retarder can also be used as a water repellent admixture for render as well as cement/sand mortars purchased elsewhere.
