Canvas re-proofing liquids - any good or just a con?

[Poignard]

My sprayhood lets the rain through. I'd like to put off buying a new one for a year or two. I see these re-proofing liquids advertised but do they work?

 

[Topcat47]

I regularly treat my waterproofs by washing in Nikwax. When My spray hood started to leak I did the same. It sort of worked for a season, but when I had the thing re-proofed by the manufacturers it lasted longer (still waterproof). Check with the guys who made yours (it they're still around).

BTW, No I can't remember what they said they used to re-proof mine.

Not quite the same thing but we did our car's canvas hood in Renovo and it made a huge difference. Water beads on the canvas and runs off.

I use Fabsil on my motorcycle clothing, spray hood on the boat etc., great suff. A bit smellie initially but this wears off very quickly and the water repellentness is excellent...


Sorry about inventing a word earlier.

I reproof my very elderly sprayhood with Fabsil annually and am very pleased with the results. I use a paintbrush and take care to avoid the window-plastic as Fabsil can make it go milky. Not everyone reports good results, however, so it may depend on what material the sprayhood is made from.

+1 for Fabsil

years and years ago oilskins were made by painting linseed oil on linen . Reproofers are a modern version of the same idea and I did the useless musto jacket I had every year after the first year I got soaked in it

+1 for Fabsil

from amazon was the cheapest i could find

 

[Poignard]

Thanks for the advice. I'll have a go at re-proofing.

I've had good results with nikwax.

+1 Fabsil, paint on best. Local camping shop should stock it.

Sprayed mine with fabsil last year. Worked well but took more than one can so ended up quite expensive and next time as others suggest I would paint it on. I still get water coming through the stitching in a heavy downpour but it's much much better than it was and not coming through the fabric itself.

If the canvas is old and has a tendency to 'sag' allowing water to form puddles which then drip through, then no amount of Fabsil will seal it.

Fabsil just makes the surface hydrophilic so it sheds water (and dirt) better, which it turn stops it becoming saturated.

Be reading this thread with interest as it is a job we need to attend to and as quite a few have recommended Fabsil I thought we would try that.

But which Fabsil do you use? There seems to be Gold, UV resistant and Fabsil advanced along with a large variation of price. Also how much do we need to buy to do sprayhood, wheel cover and sail cover?

 

[alahol2]

I wonder if this would work? It says it's OK for canvas etc. http://www.restexpress.co.uk/acatalog/Barrettine_Premier_Water_Seal.html?gclid=CjwKEAjwgYKfBRDvgJeylem9xDUSJACjeQ7AUzqh7Q9YGIb51wJ0soi8RYCBWg6fteqNzNtxqxbRlBoCA1rw_wcB
...and it's a lot cheaper.

I use Fabsil Gold, lasts longer and better than the normal Fabsil I used before. But it is more expensive.

Thank you Scubadoo

+ another one for Fabsil Gold, I give the canvas a good wash first to remove the bird muck etc with Fabsil "wash" and then brush the Fabsil Waterproofing on when the canvas is under tension ( ie in it's normal position ).

It needs to be done annually, if you leave it until it leaks then you've left it too long

I use Renovo, you do need do it each year as the canvas ages, but it does extend the life of your spray hood or cockpit tent.

Lanco Concrete floor sealer works for me on my sunbrella covers, the small print says it also works for canvas etc
