Masonry Water Repellent is a water based sealer for use on bricks, blocks, reconstituted limestone, concrete and most masonry surfaces. One application will provide a long lasting barrier to the ingress of water, the product is designed to penetrate into the capillaries of masonry surfaces and reduce the absorption of water, water-borne staining and stop efflorescence. The product can be applied on both the internal or external side of the surfaces.
Masonry Water Repellent is Non-Toxic, will not peel or blister is UV and alkali stable and under normal circumstances will not significantly alter the appearance of the masonry products. However it is strongly recommended that a test be carried out prior to application as some masonry products have pigments that may be highlighted after application.

Surfaces should be clean, dry, firm and free from oil or previously applied sealers or coatings. If required, surfaces can be washed with a strong detergent/degreaser and rinsed with water. Any cracked or damaged areas should be filled with cement based filler and allowed to cure & dry. Apply the product by brush, roller or airless sprayer, making sure that the surface is saturated. If solution is quickly absorbed apply a second coat at a rate that shows the product running down the surface.
Any product remaining on the surface after 5 minutes should be wiped off. (So as to not create an uneven surface) REMOVE PRODUCT FROM AREAS YOU DO NOT WISH TO TREAT IMMEDIATELY WITH A DAMP CLOTH OR SPRAY. Do not apply if rain or extreme weather conditions are expected.
