I contacted them and they said would be suitable

The description as "peelable" would make me a bit reluctant to try it, well that and the number of waterproof carrier bags I could get for the same price.

To add another layer of coating to an existing tent floor, this seems to be the correct stuff:

+1 for this product.
I had an old bag I wanted to use but the PU coating inside was flaking off. The small bottle of Tent-Sure product isn't cheap, but goes a long way and it saved me from buying a new rucksack, very nice! :D
It is by riding a bicycle that you learn the contours of a country best,
since you have to sweat up the hills and coast down them.
Thus you remember them as they actually are...

How good is the waterproofing since you applied the Tentsure? Did you remove all the old coating first?

The reason I ask is that I've re proofed my groundsheet and groundsheet protector, but haven't had chance to use the tent since. The old coating was badly cracked with minimal flaking, but other than that it was still intact, so I applied the Tentsure over the top of the old coating. It seems to have applied well, but I don't know how waterproof it will be, hence the questions. The video I saw on YouTube advised removing all the old coating first.

I use Thompson's Water Seal. It's about £15 for 5 litres.

It's cheaper by far than any proprietry tent proofer and more effective.

It really is superb stuff. OK, so it's meant for use on bricks etc (where it is, of course, woefully inadequate), but it works a treat on all kinds of things.

I use it on tonneau covers, clothing, tents, groundsheets, anything fabric that needs to be waterproof.

Bung it in a spray bottle, spray all over until the fabric is soaked, then allow to air dry. Waterproof for a year at least.

It is outstanding. Well known and used in this manner by certain sections of the motorcycling community.

I've been using it for years.
