Forms an effective barrier to water penetration and the ingress of atmospheric chemicals. It’s transparent finish renders it suitable for applications where it is desirable to retain the appearance of the underlying substrate. It is particularly suitable for protecting porous stone, decorative aggregate panels and brickwork against water penetration and subsequent frost damage. In addition, it provides an effective barrier to carbon dioxide diffusion, making it ideal for protecting reinforced concrete against carbonation.


Ensure that surfaces are free from visible dampness and that surface lying dust, dirt and other forms of contamination are removed immediately prior to application. Joints, edges and other details may be reinforced with Reemat Premium glass fibre matting. Fixings and bolt heads, etc. may be treated in a similar way. Allow to cure before overcoating. Note: Reinfocements will be visible.
