If the facade gets wet after a shower or rain, this is a sign that the facade material is too porous. The facade then absorbs alot of water. With a full wall this can lead to breakdown, whereby the inner walls also become damp. Moreover, it has a very bad influence on the insulation value of your facade. Wet walls are also susceptible to frost damage, which can cause joints to loosen or damage the surface of the stone.
The solution!
Impregnate your facade with WP7-401 facade waterproof
This easy to apply facade cream is very effective against penetrating water, but allows your facade to still breathe so that the water present can evaporate and your facade dries out.
