Review: Seems to work! - I wasn't sure this was going to make it for some garden cushions that tend to get soaked when it rains, but it seems to have done so. I got a hanging chair with big cushions that are made of water resistant materials (I think it's mostly thick polyester) and they seem to repel a little bit of water but when it rains for 3-4 hours, even if it's light rain they end up soaked and then, maybe due to them being water resistant, takes ages to dry out. So basically if it rains during the night, which in the UK happens a lot, don't expect to use the chair the next day, which really sucks. I tried this on the small head rest cushion and a bit on the big one, applied two very generous layers of the spray and let it dry for 3-4 days (just to make sure). I tried it on my sink and it repelled all water but again, the materials could do this on their own given it's just a bit of water. But this night it was raining and I went to the garden to check how wet they were, obviously the entire chair was wet all around but when pressing on the cushions they seemed to be dry on the inside. On waking up this morning I checked again and contrary to how it used to be (could take a whole day to dry) it was already dry. The big one was a bit more humid as I ran out of spray when spraying it and could only cover most of it, but not all, still that most of it did clearly do something as it was much drier than it would have been usually. I don't know how often this "treatment" needs to be applied, but hopefully it's just once a year or every 6 months. If so, it really is a wonder and a much cheaper option than adding a pergola to protect the chair.
Review: good product - Just as described - thanks!

## Questions & Answers

**Q: Will this waterproof a fishing umbrella ?**
A: I'm not sure but I don't see why not if it waterproofs rain jackets.

**Q: What is the coverage of fabric per square meter?**
A: that depends on the type of fabric that you are trying to seal, for instance a nylon fly sheet will need less per square meter than a motorcycle jacket, if you wish to re-waterproof a coat you may want to use a wash in solution rather than the spray tin. either way read the instructions first.

**Q: Will this waterproof a Kipling bag?**
A: I can't comment as I have no idea what the bag is made from but the spray is effective on most materials for outdoor use. The product details should give you a better idea.

**Q: Could you use this on a sofa?**
A: I think this fabric spray is for use on items that are used outside, such as tents, coats, walking boots etc.  Perhaps you could find out more from their website.
Using this spray indoors would not be a good idea as the smell is very strong and should be used in a well ventilated place.
