The Complete Waterproofing Solution for Tents and Outdoor Fabrics.

When tent flies get sticky, backpacks start delaminating and rain gear begins to fail, make your favourite items waterproof again with Tent Sure™ by McNett. Tent Sure is a polyurethane (PU) coating for waterproofing tents and outdoor fabrics. The high-performance formula makes it easy to re-coat worn areas for longer life and total water resistance. You can use Tent Sure on tent floors, tent rain flies, awnings, boat covers, backpacks, rain gear and more. If it’s made of synthetic fabric, Tent Sure can make it waterproof.

McNett Tent Sure for dive wings

Acquired McNett Tent Sure to reinforce the outer shell of my dive wing, that has delaminated over the years. Seems to have worked so far.

Tentsure. Not quite was it says on the tin.

This is really for a groundsheet that has lost all or most of its plasticised coating. All the original coating needs to be removed before Tentsure will adhere. It is no good if your groundsheet is just old & looking worn, Tentsure will just peel off. However, UKMCPro’s delivery & aftersales information were excellent. I would give them 5 stars, unfortunately for us the product itself was no good at all.
