Thread 2939562

My neighbor and I share a brick wall that acts as a wall to her bedroom, and a wall to my garden. Recently, she found a leak under her floor that is presumably coming from my plant watering as the sprinkler sprays a part of the wall. I'd like to seal up the wall with something durable and lasting. I have researched two products:

Killz masonry stucko and brick paint

BEHR PREMIUM® ELASTOMERIC MASONRY, STUCCO & BRICK PAINT

The BEHR product says it allows breathability to keep moisture from collecting inside of brick. I imagine this isn't a good idea since this seems to be what is causing a collection of water seeping through to the other side.

The alternative is that I use a product I found called castagra, which allows me to paint a surface with basically liquid plastic. But it will not look pleasing and it is extremely hard to apply.

If either of these paints prevent water from getting to the opposite side of the wall, won't it collect water moisture and pull away from the surface in a very short time?

What do you recommend in this situation? Both of these products are water based, so wouldn't that be a problem when I water/when it rains?

Messing with brick's breathability is risky, especially if where you live you get below freezing temperatures. It could be that you apply such a coating, moisture that was previously escaping through the brick is now trapped, freezes and spalls the brick.

I would just install some corrugated sheeting to shield the wall, or install drip irrigation instead of spray.

See it's this retarded logic that has ruined endless masonry around the world new and old. Breathable means water shedding but the substrate behind SHOULD (breathable is a scale and 99% of "breathable" products bs corporate lies) be able to dry out. Moisture will always end up inside masonry and it doesn't matter what reverse prolapsed tanking condom scheme of hackneyed logic one applies to it. Moisture finds a way in, and if it's arriving faster than it can leave (because the wall is now tanked) then it gets worse. By tanking the outside - and most crucial - vector for it to leave; it will be fucked. It will eventually crumble if frosted, doesn't matter how hard the bricks are. Exposing bare masonry to the wind and sun is exactly what it needs. A non hydraulic lime render is the best water shedding, but also moisture removing thing to apply to masonry. Lime generally is the only truly breathable material for masonry. But that's a big topic way above you, I don't think it's the solution anyway so do this before any wall fiddling and fucking:

I'm going to go on a limb and say the ground level of the soil on your side is too high and bridging the damp course that should be built into the walls and foundations. Or there is a crack and her foundation has failed. Excavate soil to the correct level, see how wet it really is, and remove paving against wall that stops the ground from drying. And adjust your fucking sprinkler.

knock down the wall so you have a clear path into her bedroom for sex.
