Impregnating a façade
Does your façade suffer from penetrating rain, green deposits or salt efflorescence? All this can result in a wet façade, which in turn leads to a build-up of moisture and mould or in the worst case even frost damage.
That is why it is best to provide your façade with a good, breathable rain coat.
Seems like a difficult job? Not at all, with WP7-401 Façade Waterproof you can easily provide the necessary protection against moisture and dirt yourself and enjoy the benefits for up to 25 years!
Step 1: Preparation
Remove all dirt mechanically and clean the façade.
Allow the wall to dry for 2 days after cleaning. In case of masonry repairs, allow it to dry for at least 7 days.
Step 2: Impregnation
Apply one thick undiluted layer with a coat roller or block brush.
IMPORTANT: Apply only between +5°C and +30°C.
