poor man's fiberglass or, covering my TD with painted canvas

Postby rowerwet » Tue Aug 02, 2011 8:04 pm

as mentioned in this thread http://tnttt.com/viewtopic.php?t=39373 I covered my TD with painted canvas, I used porch and floor paint as I think it is tougher, and cheap drop cloth canvas from HD.
-the canvas is wrinkled from being folded, some of those wrinkles won't paint out, you may want to iron it (or save some effort and throw it in the dryer for a spin)
-use the cheap paint for glueing on the canvas, it took me 4 gallons just to get the roof and one side canvased, the hatch is not canvased now (in one epic downpour last summer the rain found every tiny hole flooding the galley, if the hatch had been covered it wouldn't have leaked so much)
- edges, lumps, bumps screw holes, knot holes, fill and sand, any imperfections will jump out when it is painted. (use a router to put rounded edges if you want them)
-prime the wood( primer is cheaper than paint)
-cut the canvas side panels to rough shape leave a good margin around the edges
-cut the roof panel slightly oversize
-lay the canvas ,inside up, on some clean surface you don't mind getting paint on (do the sides first, use the roof as the paint area, or lay plastic drop cloth over plywood) and roll on the paint nice and thick ( I used 8 oz canvas and it soaked up tons of paint)
-roll a thick layer of paint on the part being canvased
-lay the wet painted canvas, paint side down, onto the area, roll out any bubbles and wrinkles with a paint filled roller, keep rolling on paint until the canvas stops soaking it up. (watch for drips on the edges) :roll: :oops:
-make sure any edges for hatches etc. are painted to hold them, I found cutting my round windows worked better after the paint dried, for square openings like my door cutting the canvas while wet and gluing it to the inside of the door frame worked well. (I've reworked my doors three times since, I wish I'd had them right the first time to protect the inside of the door rabbet)
- trim, vent covers, installed while the paint is wet will glue themselves in and if you try to remove them they will take some paint :( (using the paint to glue everything in makes a better waterproof seal, since canvasing I've redone my vents, RTV seals just as well on porch paint)
-after the paint dries the canvas will look dry if it soaks up like mine did, I let it dry and then painted in a top layer of expensive gloss porch and floor paint (kind of a waste, I now like Glidden better than the expensive Behr paint after more than one paint failure on my mouseboats using Behr)
-I like the textured look the canvas gives but the cheap canvas drop cloth has lots of pills and strings, get better quality cloth if that bothers you. (bed sheets material, more expensive by the yard, however much less paint=less weight, and the same strength to the paint, thinner fabric will not hide as many surface defects :oops: )
-bugs are attracted to fresh paint :cry: (and Maine has plenty of black flies...)
-make sure you know exactly where the door hinges attach (this got a lot of paint on my gloves and screw gun that shouldn't have :roll: )
:x
-rain will leave grooves in fresh paint :x :x
-pinking shears will make your edges look much more finished
hope this helps!

Interesting idea, a cheaper version of fiberglass/epoxy :thinking:

Thanks for posting this

cost
20$ per gallon for the cheaper paint (4)
27$ per gallon for expensive gloss paint (1)
25$ for the 12'X15' canvas drop cloth (1)
not counting roller or pan 132$

Thats about what I'm paying for one gallon of epoxy and a quart of hardener. It'll be interesting to see how it holds up.

No, one gallon will not do my entire TD (5x9 Benroy). Also, I'm not glassing my entire TD either, just reinforcing select areas. I'll be using 3+ gal on my project.

Epoxy is not UV stable, so it has to be painted. I'm currently looking into having the boat place I'm getting the epoxy from spray on a 2 part linear polyurethane paint.

if you have a significant other... get a pair of scissors that no one will mind being covered in paint, as you will be doing a lot of cutting while the paint is still wet, I bought a new set $5 so my wife couldn't complain.

Rowerwet,
are you using latex paint? If you are I suggest you check out the method the canvas cedar covered caneo builders use. As you live were lots of cameo builders are, it should be easy to see how it's done. I'm pretty sure the canvas isn't paintecloths dropcloth. The paint is oil base.

In our build (Horny Tow'd), we used titebond glue to stick the canvas down to the plywood. Then after it dried, we sealed it with thinned paint and followed up with a few coats of full strength paint.

We really like the look of the textured canvas.

yes I know how the professionals do it, I was looking for cheap, cheap, cheap. So far it works great. getting oil based paint around here is expensive.

in case anybody was still wondering, the paint has held up just fine. the tear has lived outside all the time except for a few months last winter when I yanked the trailer out from under it for moving. Other than a a few stains from leaves which I am too lazy to wash off, and some bird stuff, the painted canvas is just as inert as the day it dried. I haven't painted it since the day I put the canvas on and won't need to for a while.
the street side of the tear was never canvased, the paint needs some work and the plywood has some issues that need to be fixed now.
When I put the tear back on the trailer two summers ago, I cut away the stupid 2x4 frame I made to "support" the floor, I had to peel back the canvas along the front and curb side, the paint tore the top layer off the plywood with the canvas. TALK ABOUT GOOD STUFF CHEAP! :thumbsup:

How did I miss this thread ...? I wish I had seen it sooner, there's a lot of good info here !

Here's my experience, which is on Foam, but should be similar to plywood...

I used a total of 3 gallons on the outside of The BiG PInk.

1 gallon of un-thinnedTB2 to glue the canvas down. I painted it on, laid on the canvas, and used plastic scrapers to work the glue through the canvas. The canvas did shrink quite a bit. I painted the back side of the canvas on the edges which soaked in and made the canvas a lot more pliable to work it aroung corners and such.
I also used 1 gallon of Floor and porch paint (oil based), two coats pretty much took all the texture out. But Mike had bought some nice finished canvas which really helped.
And I used a 3rd gallon of aluminum roof paint for the "roof". This didn't fill in the weave, and left a very nice textured finish.

I did the front side first, and learned that I should have done the back first as I got much better at working the canvas. I found i was able to get it smooth around and into corners if I kept working it.
Like Rowerwet, I also did the winows after the glue dried. Make sure you allow for the thickness of the canvas/paint when making your door and window openings !

Desertmoose, the Horny Tow'd looks great !

I will be looking for any more tips from yall as I near that part of my build. Would anyone suggest putting multiple coats of TB2 over the canvas, then sand, prime and paint? THANKS!
