Steps, you almost certainly have acrylic canvas. Poly cotton canvas shrinks up to 10% and fades badly if exposed to lots of UV. Acrylic canvas is used on most quality boat covers and outdoor furniture.

 OK how could one tell?
 maybe burn a few fibres somewhere.. melt or smoke?

My past company manufactured the solution in NZ (Penrose) I've used it many times satisfactorily. I'm about to redo my Black Canvas Canopy on my boat in situ when this weather clears.

Any marine canvas work done by a reputable trimmer will be acrylic canvas,

 Mine is cloth type canvas, not acrylic or plastic coated/ impregnated, made by a very long established company  been up for near on 7 yrs, all stitching in excellent condition.
 Clears as clear as the day they where made.. The only things that have deteriorated are the velcro stitched to the roof for the screen clears hatch to fix back onto so dont flap in the wind when open ( bad idea in the 1st place)
 And the upholsterers stitched on logo patch faded to nothing. Oh and the dark brown canvas colour has faded only slightly.

Kandrew said his canopy was black canvas, almost certainly acrylic canvas. Any marine canvas work done by a reputable trimmer will be acrylic canvas, which has very different properties to poly cotton (tent) canvas.]]> Mon, 12 Feb 2018 16:07:06 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=127215&PID=1717806&title=rewaterproofing-canvas#1717806 https://www.fishing.net.nz/forum/forum_posts.asp?TID=127215&PID=1717770&title=rewaterproofing-canvas#1717770 Author: Steps

Mine is canvas.. tent canvas.
 Gets a water proof every yr..its a 'maintenance' thing not a repair thing.
 scot gaurd also works well as a protectant after the normal canvas water proofing..espec for protection against salt and bird poo.. leaf debris etc.
And a non bleach type disinfectant (gone in 60 secs concentrate @ 10%) in a spray bottle around stitching and behind where clears over lap.. canvas side.

You need to use a waterproofer for acrylic canvas, (like 303 Fabric Guard) not tent canvas waterproofer which is poly cotton canvas. 303 Fabric Guard comes in a spray bottle and only needs a light coating to work, don't make the canvas wet or you are just wasting the product (and money).It's a good idea to wash and dry the canvas first using a very mild soap or detergent.

There are a bunch of products for tents that work just fine. Have used a few of them over the years and can't remember the brands sorry, but all the ones we have tried have worked pretty well. ]]> Sun, 11 Feb 2018 19:38:48 +0000 https://www.fishing.net.nz/forum/forum_posts.asp?TID=127215&PID=1717728&title=rewaterproofing-canvas#1717728
