A premium waterseal designed to repel water from exterior masonry work which allows walls to breathe, reducing the risk of damage caused by water and frost. Used as a masonry water-proofer suitable for use on brick, stone and concrete. It protects against water and frost, providing a breathable coating which does not change the physical appearance of a building. A secondary benefit of the product is to repel water-borne dirt and resist fungal growth as well as help reducing heating costs, as energy is not wasted in drying out wet walls. Offers years of protection. Brush at a rate of 3m² per litre for porous stone and 5m² per litre for hard brick, allowing 6 hours to dry before applying a second coat. Always apply with a smooth action starting at the top and working your way down the wall. Care should be taken not to splash or mist cars, windows, painted surfaces, plants and ponds. Two coats are recommended for best results, however more coats can be applied. Apply by brush or non-atomising spray.
