I have bought this water sealant a few times now, to proof the exterior of my 160 year old sandstone/whinstone house. It does a great job of repelling water - walls that would have previously taken days to dry out after a rainfall now dry much more quickly. This seems to have improved the thermal retention of the house too (albeit marginally). I guess less water to evaporate from the stone means less energy disappearing into the atmosphere. I'd been skeptical about how well such a simple thing would work, but it does seem to. I have one wall with harling/pebbledash on it - I haven't tried to waterproof that, as I'm conscious that any water which got to the inside of this might not be able to get back out. I'm not concerned about the same thing with the stonework. Just make sure the stone isn't waterlogged when you first put it on, or you could trap moisture which will expand in freezing tempratures and could damage the surface of the stonework.Read full review

Purchased this water repellent to prevent frost damage in brickwork. Reputable product. Very easy to apply with garden spray - avoid windy days. 25ltr is much better than 5 ltr packs.particularly from Platinum Supplies. Container is robust and watertight. It does the job very well, good price and excellent service.

I had repointed my roof tiles and decided to waterproof my roof, was going to use Another branded weather seal but very expensive £25 for 5 litres, whereas your product Water Seal 25 litres was only £49. Used it on my roof and I am very impressed with the results so far after couple of nights of heavy rain. So I would recommend your product to anyone. Thank you
