Exterior masonry water repellent treatment.
A water repellent surface treatment of above ground exterior masonry to prevent penetrating damp.
Specially formulated to be alkali resistant for use on new mortars or renders. It is used to stop external penetrating dampness and its main feature is a water barrier but not a vapour barrier. It therefore allows the masonry to breathe and reduces the danger of condensation such as can occur if an impervious treatment is used.
Sovereign Masonry Sterilizing Wash is recommended to help remove any lichen or algal growth from the substrate prior to application of the treatment.
