To properly seal an exterior wall, choose a waterproofing coating that matches the material. For brick and concrete, for example, using a concrete waterproof paint coating will do the job. Or you can use a silicate-based concrete sealer which will create a waterproof coating on the surface of bricks and concrete.

Follow these steps to apply the waterproofing agent: Pour the waterproofing agent into a bucket or a garden sprayer. Starting at the bottom of the wall, apply the agent generously to the brick surface. Work in small sections to achieve even coverage. Allow the first coat to absorb for about 5 minutes.

If the external side of your wall is exposed brick or unpainted render, you can apply one coat of façade cream such as PermaSEAL Facade Cream, Remmers’ Funcosil FC or our professional-grade Microshield Ultra to protect the wall from water penetration for up to 30 years.
