Since no-one has experience with Snow-Coat on canvas, I will tell what I
know in how I have used it before...

I have a travel trailer that I have used this product on for the last 4
years. It has absolutely no fume problem. I did not wear any kind of
respiratory protection and have never felt the need for any. The first
application on the 18 year old aluminum roof lasted for 3 seasons. I
live at the 4,000 foot level in the northern Sierra Nevadas. We get up
to 4 feet of snow at a time, hail, tons of rain in the past El Nino
years, and 95 degree summers.

At the end of the third season, the Snow-Coat (it was the one that is
bookmarked in another post today. Sorry if the name is wrong.) was
chipping badly. I have thought of using this product on a canvas cover
for a yurt, but my concern was that I was interested in transporting the
yurt at times. My fear was that the Snow-Coat would not be pliable
enough to withstand some folding necessary to transport. I did think
that it would work just fine on a stationary yurt cover, but never tried
it. In fact, one manufacturer of canvas outdoor domes suggests applying
Snow-Coat to the canvas as a waterproofing agent.

Two questions I would have with this product are:

1) Will it be able to withstand the slight buckling necessary?

My guess is yes if we are talking about a non-folding kayak.

2) What do you do to the canvas when the Snow-Coat finally begins to
pock? Re-canvas? Find something to remove the old Snow-Coat and then

I hope this helps.

At the price and for the low toxicity, I may give it a try.

My guess would be for 2 undercoats with the gray and one overcoat with
the white. The gray definitely has more give and more applicability.
Gray alone maybe.

Also, very important!

Do not store this anywhere it will get cold. It must be kept in your
house where it will stay warm. If you let it get too cold while in
storage, it will separate and become useless. I learned the hard way.
