HYDROSEAL PX is a cementitious waterproof slurry coating, for application to masonry and concrete substrates. Its unique composition produces insoluble crystals which effectively seal the micro-pores and capillaries to prevent the passage of water. It is a single component product which is just mixed with clean water and is easily applied by brush, trowel or spray equipment.
HYDROSEAL PX is used for the effective tanking of substructures including retaining walls, basements and tunnels. It is also suitable for application to masonry walls to seal against rising damp.
