One Chem Tent and Gear Waterproof 2 x 5 Litre Refill, Multi-pack, Effectively Protects Tents and Gear From The Elements

Worked very well on my awning that before treatment was allowing a lot of water in. At the time of this review I'm sat in the awning and it's pouting outside. The awning is completely dry inside. 1 treatment with a garden sprayer and it's as good as new. Definitely worth a buy!

Very thin and you end up buying more to get good coverage (at least we did for our canvax saxon re-enactment tent), but it does the job, keeps the rain out - fabulous :-)

Good value waterproofer which is easy to apply. Included is a spray attachment which unfortunately did not work but thankfully I had a garden lance spray which made the job even easier.

The first tub didn’t have the silver seal or the sealed bag and didn’t seem to make any difference with waterproofing my awning as the rain still came through but I didn’t notice until I opened the second tub which had the seal and seemed to work better!! I do wander if this was a returned and wasn’t checked?!!
