Waterproofing your canvas

[AMacA]

Folks,

I'm looking for some recommendations for waterproofing a canvas marquee. A bit of Googling suggests Grangers Fabsil, Nikwax cotton proof or Storm Canvas Waterproofing.

Anyone used any of these with good results? I've seen mixed reviews for Thomsons Waterseal, so I think I'll avoid it.

Cheers!

Fabsil - not used the others.

I've used the nikwax stuf on my tent and it doesn't leak, but also heard good stuff about Fabsil. My experience with Nikwax Tekwash and TX washin waterproofer on my bike kit would lead me to stick with nikwax as thier other products work well.

I have used Storm on my vintage car canvas roof with 1st class results, waterproof. The car I used it on has a roof canvas of 88 years old and leaked like a sieve when I purchased the car, says it all really.
edit to add, a vast difference between modern fabrics and old fashioned canvas, modern waterproofing liquids failed on my car roof.

Ive used fabsil and cotton proof on jackets to great effect.

We use Fabsil on the nylon flysheet of our roof tent, and have used it on the mahoosive canvas awning that goes with it. Never had a problem, great stuff.

You usually need more than you think, it's amazing how much gets soaked into the fabric.

Another vote for fabsil. Used it originally for my leaky seamed vx220 roof and then out of curiosity on our cheap three man tent. Worked brilliantly on both. The rain water beaded lovely on the vx220 roof and no longer leaked through the seams on to the sill. From memory it lasted about six months before reapplication, but the car was stored outside. I haven't needed to reapply to the tent!

Thanks for the replies folks, 15 litres of Fabsil ordered up. Hopefully no need for umbrellas inside the marquee at our youth group's summer camp this year!
