Single Skin Brick Garage - Sealing

[MondeoMan1981]

Can anyone share experiences / products for sealing a brick built single skin double garage? I'm in Scotland, and we get a lot of rain , so now that the new build warranty is up, I'm thinking a breathable sealant will make sense to protect contents and the garage itself. Guessing this is fairly common and others will have experience to share. This is my first house with an external garage - will eventually house a little something for weekends...

‘Something for the weekend?’ Oooh, suits you Sir, something racy is it Sir, oooh. Any how, moving on, do you get damp showing inside? If not leave it alone. Google Stormdry cream for a a clear waterproofer on the outside if you do have problems; or if it’s bare brick inside and you want to tidy it up, have a look at Zinsser WaterTite.

Are you having any issues with water getting in at the moment? We have a new build external garage and were dealing with serious moisture issues. Turned out the threshold for the side door was missing and the 1.5" gap was allowing the wind to drive rain inside the garage... enough for it to cause the racking shelves and any fabrics to go mouldy. whole door and frame replaced under warranty and issue resolved.

No real damp inside it, plenty brick salts and just general damp air when it's wet, contents feel dry. Couple of things have gone mouldy but they were dirty, so kind of expected (food stained straps of an old high chair)

Storm Dry is really quite effective stuff and the best type of brick sealer I have used personally.

You could render the outside and paint it which would look nice too.

Came here to say the same. We bought a new build in 2023 and I was annoyed to find it was single skinned and could tell in heavy rain in the winter it would soak through as the builders had left a sprinkler on next doors garden and it was hitting the sidewall and inside the garage the bricks were damp,

I bought the same stuff mentioned above, Storm dry is great and has a 25 year guarantee. I made sure I took my time and did it in sections. It took me about 3 days do it but hopefully it will out live me being here for sure. Garage is now fully sealed and it works a treat.

Or clad it in something?

The trouble with water repellent products is that they eventually stop repelling enough water to keep the building dry, but still seem to repel another coat of magick jollop.

Tanking slurry to the inside would do the trick, low tech and hard to muck it up (even for me)!
