Has anyone tried using Sunbrella material and then putting a clear coat of some kind over the material?
Maybe polyurethane?
Would it hold up like the canvas and exterior paint treatment?

It would depend on how paint stuck to sunbrella, really you should buy the cheaper fabric that matches the texture you want, the paint is the real protection.
Any fabric will fade in the sun, painted it cannot

I wouldn't think paint would/could penetrate sunbrella like it can canvas?

Time to get back to work on my little trailer. I just ordered some canvas from the Internet that has no seams and is preshrunk. The canvas I purchased from the big box store last fall was full of seams.

I didn't think about the Sunbrella fabric repelling water/paint.
I could make a test board and see what happens.
Thanks for the info.

Yes, I'm a big fan of doing test pieces- that's how I found out I could use CDX plywood on my walls. By accident I left a small piece of clear CDX in the backyard and picked it up a year later= no delams at all. The secret was finding CDX with very clear faces= takes time and a lot of sorting through bunks.
Waiting for a mockup test to yield results takes time and we know how short the building season is up north.

Great info in this thread! I'm still at the wall-building phase on my benroy right now, but starting to plan for covering.

Sam, I read your instructable and it's perfect. I'm going with canvas and TBII on my build. One question I haven't found an answer to yet...

When you are doing the glue -> canvas -> exterior paint process, are you throwing the first coat of paint onto the glue/canvas layer while it's still wet or waiting until that all sets up first then painting? My guess from prior painting projects would be that you let the glue and cloth set up and harden first then paint, but you mention impregnating the canvas, and I can't imagine that working well once the glue is cured.

Thanks for you instructable and to the whole community for an awesome forum.

The glue just holds the canvas to the wood. it doesn't fill or impregnate the weave of the canvas.
Roll/ brush the glue on, smooth the canvas on and let it dry. Trim overlap at edges, brush glue at the overlap and wrap canvas around edge. Let dry. Apply canvas on other side the same way, and you end up with a double layer of canvas at the edges.
After all canvas is applied, paint with thinned paint so it soaks into the canvas. then paint to the desired finish.

Actually real easy to do.

You are now done with the Titebond. On top of the BARE canvas, put a coat of exterior house paint thinned about 50% so it soaks into the canvas. After that dries, use full strength paint until you get the look and coverage you want. Ours took 4 coats.

Titebond 2 works great. No need for the more expensive Titebond 3 since it is protected by the paint.

Others have used the Titebond on top of the canvas to try and cover the surface. But glue isn't made to cover, it sticks things together. Use it as intended and stick the canvas to the plywood. Then use the paint like it was intended, cover for waterproofing, appearance, and protection.

We used exterior latex. others have used exterior oil based. Our experience with the latex has been great. 2-1/2 years in the Nevada sun, snow, rain, and thousands of miles of towing. If I ever build another trailer, I WILL use the painted canvas covering.

i used 10 oz canvas drop cloths from Harbor Freight. Cheap enough, especially with a coupon, but I did end up with a seam on the roof and sides since the drop cloths were sewn from small pieces. Look above the door and you can see one of the seams. We haven't had any trouble with having seams, other than appearance.
