How does rain penetrate the wall of a building?

Rain penetration into masonry (penetrating damp) can occur in buildings of all ages. At its most obvious, it penetrates right through the wall and is visible as a damp patch on the internal wall – often causing discolouration and peeling / flaking of paintwork or wallpaper.

Can a water repellent be applied to a wall?

Water repellents can also be applied to the external face of a wall. They then penetrate through the fabric of the wall, making it repel moisture. However, the wall remains permeable to air movement, and so water vapour is still able to pass through the wall, reducing the likelihood of a build up of damp from the inside.

Do you have to re-seal your deck after rain?

Because it forms a coating, it takes several hours to “set up” (dry) and during that time the sealer is vulnerable. If the surface dried enough to touch and the rain was gentle, you may find no problem at all. If the surface wasn’t dry, or if the rainfall was hard, you will probably have to strip and re-seal.
