Canvas waterproofing
 

We're making another sales booth because he's not happy with the one we have
:-(

He's made the frame and we've sourced samples of cotton canvas which will be
light enough for us to manage but will need to be waterproofed just in case
it ever rains ...

The last time we did this we used a product (name forgotten) which was
excellent but it made the canvas heavy and slightly sticky, also smelly.

He's prepared to use NikWax but is fondly remembering a water soluble
preparation from a hundred years ago called, he thinks, NevRot - or
something similar.

Does anyone remember the stuff or know if it is still available?

I got some for waterproofing tents, it was in a pump handled sprayer (not an
aerosol) and it was water based - I used it for my cotton fishing umbrella
and it's never allowed a drop of water through, nor does it smell or leave a
visible residue....I got it from a camping shop, I'll try and dig out the
half bottle I have left over and get you the name of it....

It's Nikwax, as mentioned by your hubby...it's still available and I got
mine from Millets:

It is good, we've used it several times in the past. It's very easy to get
too, but thanks for your input. It's just that he got all dewy-eyed thinking
of his happy tenting days in the 1940s.

Just make sure you get the cottonproof stuff and the wax for boots :-). I
always used to use Fabsil which you could get in small bottles or
multi-litre containers. Just put the tent up, paint on the gunk and leave
to dry, job done.

I wouldn't mind using Bacon fat, it would be worth the rats ...

Neetsfoot oil is great for waterproofing, stick and smelly, but AFAIK
only used for leather.

If it's water soluble it won't be much good for waterproofing, will
it? :)))

Neatsfoot oil is used to soften leather, not for waterproofing! We've used
it a lot for that, we don't find it sticky (it's rather thin) and it doesn't
smell bad.

Yes it is. NikWax, is put on wet and allowed to dry, whether on canvas,
leather, suede or anything else. In fact on footwear the item has to be wet
first.

Sounds odd, I know, but it works.

Others who've used it would say the same.

Go to http://www.nikwax.com/en-gb/index.php and follow any of the many
links.

The water is only the 'carrier' of the active ingredients, once the water
evapourates, the waterproofing agents are left behind.
I've used it recently on an ancient cotton fishing umbrella which I found in
a skip and it's never leaked once....I have a 'newish' umbrella too, made of
some kind of pvc fabric, but I treated the old one to keep as a spare (in
case of a high wind/deep water related disaster)

I used it on a leather jacket once. Kept me dry on a bike going from
London to Cornwall - in pouring rain :(((

Messy stuff though, comes out of the leather like polish does, if too
much is used. Might not have used it if I'd know it was boiled up
shinbone or some such...

I stand and sit corrected!

I thought with cotton canvas you were supposed to water it when new so
that the fibres swell and make it waterproof. Iseem to remember that's
what was done with tents in the olden times.

But as it dries the fibres shrink again :-)

Closely woven canvas will withstand a certain amount of rain on its surface
because of that property but if it's touched on the inner surface the water
will come through.

The watering of new canvas tents was to induce the one-off shrinkage
(irreversible) which will tighten up the fibres and make them more water
resistant for their life (the swelling when wet is mostly non-existent or
irrelevant).

Touching the insides of wet canvas tents is (as Mary suggests) a Bad Idea as
the surface tension of the water and the weave granularity of the canvas
(minimised by what shrinkage was available) is what makes them
impermeable(ish). Touching the inside with (especially greasy) fingers will
affect the surface tension of the water trying to move through the canvas so
that it can.

Extra waterproofing for canvas tents is best provided by spraying (when
erected and dry) tents with a proprietary product such as Fabsil, a silicone
spray treatment and leaving it to dry. Fabsil is available in gallon
containers from good camping shops etc. It turns grass black, which is a
bummer if on your lawn and I use a garden sprayer. The sprayer can be
cleaned by spraying through with a bit of white spirit followed by water but
reserving an old sprayer for this use is advisable.

I should have added that wetting new canvas tents to tighten the fabric must
only be done if they are fully erected and pegged out. This prevents
dimension shrinkage while allowing tightening of the fabric. If you don't do
this, putting up the tent may become problematic!

Not true - as we know from a bad experience. We relied on that once :-(

Canvas shrinks more after being agitated in hot water too, I'm just taking a
break from ironing thirty metres of cotton canvas for the new structure. it
will be worth it, we don't want the problems we had last time.

Indeed. That's why it's important to keep a flysheet away from an inner
tent.
