my new garage has a 4" brick wall which gets damp on the inside when it rains heavily. Is SIKA GUARD FACADE PRO good for solving this problem? can it be applied to the outside of walls when they are still damp, or do I have to wait for a very dry period ?
This is not a product we stock, but assuming the external face of the wall is bare, clean, dry, sound and prepared as detailed in the technical data sheet we can recommend Sika Water Seal.
The walls must be dry for application.
