Waterproofing inside garage

lagi · Post by **lagi** » Tue Mar 24, 2009 1:04 pm

Now the summers here and i can empty everything out...

I have a garage thats built out of blocks, one side where it joins neighbours there was no room to render the outside. When it rains heavy the blocks get damp on the inside. I am looking for some sort of paint coating that i can apply and it will seal the inside. Then i can paint that wall white like the rest.

What sort of stuff should i be looking for or can anybody recommend something?

Would be better if you could paint the outside with that water proofing liquid, no idea what it's called but it looks like paraffin, if access is impossible I suppose if you put enough on it would soak through anyway.

Must find out it's called as my garage does the same thing, mind the roof leaks like a sieve at the moment, I had a peacock doing a war dance all over the clay single Roman pan tiles

There is about a 1 foot gap but can't see how i could possibly get in there or a tool to get in there.

Really need an internal solution.

Just seen this, so looks like there is stuff out there

Wouldn't recommend that, any water coming through will just push it off, I think you need to seal the blocks to stop the penetration.

Yeah that is probably your best bet if you're unable to do any external protection. Although you'll need to do about 3 coats and you'll have to render over it afterwards before painting the wall.

Didn't want to do any rendering its a garage. Would like something you could just paint over when its dry.

As Scruff says you need to tackle this from the outside, just coating the inside will trap the moisture inside the blocks and probably move it further along the wall, if you can't render outside then i would coat with synthaprufe, if it is going to be seen then maybe waterseal and paint with weathershield or similar

leebwk, whats the clear/blueish liquid that looks like paraffin called. ?? used for sealing blocks, bricks etc.
Thinking 60/70s now so maybe not made, or something similar.

Scruff, sorry mate can't think of what it is called, but i'm pretty sure it's not made anymore, although i think there are a lot of alternatives now ie super seal or water seal

Liquid Rubber will seal it. I did a cellar with it 3 years ago, stiill dry.
