Rated 5 out of 5Â by axleg Just too add to others....
Very easy to apply even in cold weather. Just need dry weather so it can dry as it is water soluble. However the roof doesn't need to be totally dry before you paint.
A useful feature is that the black product is grey when applied. Makes it really easy to see when applying another coat.

Rated 5 out of 5Â by Castlemark Fabulous product for shed felt
I always use this to seal shed felt when I have re-felted a shed. It goes on easily, dries to an even texture so it looks good, but it also keeps your shed watertight for a LOT longer than just the felt!
Like all Thompsons stuff, I have tried other names but if Thompsons do a version of what you want buy the Thompsons one!

Rated 4 out of 5Â by neal57 Water Proofing
I used this product to weather proof a garden planter, not what it's designed for I know. However the product went on really well to untreated wood, I've given two coats and it has lasted longer than I thought so still have half a tin left. Only time will tell if it has done the job but initial signs are excellent. Only gave a good rather than excellent due to only having used it recently so no idea if it works long term. Item was purchased on sale but if buying at list it does seem expensive.

Rated 5 out of 5Â by MT0987 Best roof sealant ever
Had to repair my garage roof so I can at least servive winter..
On my garage roof one of the ply is almost rotten from the edges. I used this sealant in the edges let it dry for couple of hours and the. Cut a new felt for the size ( patch work ) and seal that on the edges and also cover this new piece of felt with this sealant ..
It been raining since that day .. But touch wood I have no leaks at all !!!
I used this as a work around .. Once I get the open season I'll replace my ply wood for permanent solution .
