Hi,
I am looking for an affordable way to make a new Expensive large canvas cotton "Sunforger(silicone treatment)" factory treated tipi last decades.
The maker says the canvas only lasts 5-10 years tops, if left up all seasons as we do here in Colorado.
The maker only recommends treatment with this "CANVAK" water resistant product that has some terrible reviews for poor effectiveness...
www.amazon.com/Canvak-Resistant-Preservative-Industrial-Treatment/dp/B076KXH441
With research, I've read that, the smelly at first, wood preservative liquid copper-green can be used on canvas although it doesn't have a UV protector.
It turns things a greenish color that turns into a tan color over time in the sun.
Although I'm not sure UV is what kills exterior canvas, I think it’s fungi and such, but I really don't know anything for sure.
I do know that for exterior wood, wood preservative products(like copper-green) that make it inedible to the fungi and such is MUCH more effective than water proofing products such as painting wood. That's why our telephone poles last for almost a century, of course they are pressure treated with the wood preservative so it's forced in deeper.
It seems for the most longevity, next year after the factory treatment has worn, I should spray the canvas with the wood preservative then after a year, paint the canvas with a watered down paint.
Wondering if you have any input and why you didn't mention wood preservative since cotton is mostly like wood.
This ArmorAll copper 2 maker lists canvas as one of the side uses:

This also mentions such product's general use for canvas:

Well I'm hoping to draw from experience from anyone.
Thank-you for any assistance
