Tech-Dry® Mud Brick Water Repellent is a solvent-based silane/siloxane impregnant for mudbrick or other rammed earth bricks, walls and buildings. The product is designed to penetrate into the capillaries of substrate surfaces and make the substrate water repellent. It is suitable for use on rammed earth walls as well as mud brick walls.
Once applied, it provides long term protection against water penetration, mould growth and efflorescence, as it reduces the absorption of water into the rammed earth building. It also provides protection against water-borne staining materials which are responsible for the bulk of the deterioration in earth building materials and rammed earth walls.
When applied on mudbrick, rammed earth bricks or other surfaces, the treatment will not significantly change the appearance of the substrates and the vapour permeability.
