Failed.

Two coats, applied as per the instructions. But the inside of the shed wall is soaked, puddles on the floor, and I can see the water dripping off the damp course.

😐

Not used this, but comes highly recommended, Kingspan & Celotex spec. it on occasion where residual cavity has been compromised.

Storm Dry

Not cheap though. Thomsons was bad enough but obviously worse value now.

Failed on my wall with heavy driven rain. I’ve got weather shield facade cream but need a dry week to use it so probably looking at late spring.

Why would a company that sells cheap holidays to kavos and obsolete business directorys excel in waterproofing products?

What were you expecting it to do ? Make your single skin breeze block shed water tight ?

That wasnt going to work

Batten the wall then screw some tannelised shiplap to the battens. This will keep the worst of the weather out. You could always tank the inside walls, batten them out (add in some 1 inch celotex between the battens) then ply line the shed. This is what i did to my single skin brick shed and its dry and warm.

Paint them with Flexacryl.
