Mud Brick Water Repellent is used as the final protective finish after the wall is rendered to provide a durable exterior water repellent finish.

Tech-Dry® Earth Bonding Emulsion is a PVA-based emulsion which has been specifically formulated to be used as an earth render admixture to provide bonding and adhesion. It imparts an excellent long-lasting bonding and adhesion to the earth render. It also provides flexibility to the earth render to reduce earth render cracks. Earth Bonding Emulsion is also used as a primer or sealer to strengthen and dust-seal earth wall surfaces.

Tech-Dry® Earthaid is a water repellent admixture for earth renders. Earthaid reacts with earth render ingredients to impart durable water resistance to the entire body of the earth render.
Tech-Dry® Mud Brick Water Repellent is used as the final protective finish after the wall is rendered with the earth render.It is a siloxane-based penetrating water-repellent sealer which provides excellent long-lasting water repellency to the render without affecting the surface appearance and permeability of the earth building.
