One Chem - Tent and Gear Waterproof 2.5 Litre Spray - Long Hose Trigger - Effectively Protects Tents From The Elements

Ease of assembly easy use once known how workWork well on big tentNo problem once dry

Used on old caravan awning that was so old the rain would run through any stitching and seep through the material.Used 1 entire container on the roof and 90% of the side panels of a 8m x 3m awning. We used a 5l pressure sprayer because of the large area we needed to cover, I would recommend this over the trigger spray that comes with the bottle.Following night we had constant rain, not heavy but one of those nights when it doesn’t stop and everything gets damp. But the inside of the awning was dry, no leaks around the seems and the inside was dry to the touch - there were a couple of areas we missed and they were wet through still.Might even give this a go with some coats/jackets that have lost their waterproofing.

Superb product, not the cheapest but surely one of the best, ordered 2 but only used 1. Used on a boat cover, beside the rugged west wales coast, two days later very heavy rain and no water ingress, easy to apply and the included hand spray makes application easy, even for a novice like me, would recommend and use again. Looking for other things to waterproof, ie backback and coat.

After seeing a few negative reviews I thought I'd leave my own.Firstly (and this may seem like common sense to some) but the tube with the filter on it that sucks the liquid out of the bottle needed pulling out of the lid so that it had enough length to reach the bottom of the bottle. It arrived with the end of the tube right up close to the lid, and therefore wouldn't have been able to suck liquid out.As many others stated, at first my trigger didn't pump the liquid out. So I let gravity help me out and held the bottle above the trigger so that the liquid flowed down the pipe. Once I did this the trigger worked and I could lower the bottle.It is very tiring on your hand to keep pumping the spray (I was re waterproofing a canvas gazebo) but it did the job of re waterproofing perfectly.Overall I'm very happy with the product, you just might need to use a bit of common sense to get it working properly.

Easy to apply but not completely waterproof.

Good value for the money , works well on the shoes as well as jackets

Good supplier arrived on time ,good spray gun easy to use and value for money . Have treated fishing jacket and waders with no detrimental affects ,time will tell but so far so good

Having had a couple of leaks in my 2nd hand tent at a recent festival I decided to re-proof the fabric. Easy to use & apply as per instructions. Not sure of other reviewers’ issues with the spray mechanism, I found it easy & effective to use. After application and leaving the tent for a couple of hours, I completely drenched the tent with a hose, targeting the areas where it had previously leaked. Absolutely dry inside with no signs go of any water penetration. Absolutely delighted!
