Re: make roof canvas waterproof?

I am having the same probelm with my camper top on my fishing boat and was going to use a bees wax waterproofer on it, it is intended for shoes I think but should work pretty well, they have sprays that you could use but I have never been real impressed with them

If the water is pooling, then nothing will help. You must stop the pooling by using rods, braces or some other means to raise the pooling area.

Yep. By canvas enclosure do you mean boat cover, or camping enclosure? If it's your cover you can simply put grommeted holes in it to accomdate push poles and your problem will be solved. If it's a camping enclosure you may have to get creative.

I use 303 Fabric guard. That is what Sunbrella recommends and it works great but if water pools then nothing will work. I had water pooling in a couple of spot and I picked up a couple of adjustable shower curtain rods from wally world. They have rubber ends to keep them from slipping and you simply extend and twist to lock. No more pooling. Not a bad solution for less than $15 I already had 4 poles that came with the toon but over the years pooling caused the cover to stretch a bit near the rear gate and on each side of the bow.

yea its the canvas roof, it has all the rods in top, but seems canvas pockets between them when raining and drips inside, wouldve thought being for a boat it wouldve been waterproof

303 Fabric Protector is the best thing you can use.

I understand the stuff will work for 3 years on an automobile convertible top.

There's not much you can do about the pooling--other than somehow take the slack out of it with poles, etc.

I recently used Thompsons water seal on my canvas pontoon cover. Water beads up and runs off. Cover looks and feels the same as before I sprayed it. Anyone else used this product?
