I am going to run a few tests with these materials to see what might or might not work in the 17 ft. Boler.

Note: there is a possible problem with my Flickr link. I will repost photos.



Thanks for the info. Donna. However I still can't figure out my Flickr. (I guess I should stick to Youtube)

I will make a short video and post the Youtube link.

Try this Youtube link.

Too, Kevin remember Flickr usually puts in an "at" sign in the URL, if you wish to post a link containing that... you'll need to convert it to a TinyURL.

Here is the Youtube link for the experimental products to insulate and line the interior of the 17 ft. Boler

Interesting, I saw this product at home depot. I'm going to give it a try. I also saw the "eco cork underlay' trying to compare the two. They seem very similar, except the cork you may leave as is, because it's a tan colour if you don't ming how it looks. Price seems good. Instead of painting am going to use the vinyl decking material they sell on the big rolls. I like the texture and colour. A friend has some that I'm going to try out to see how easy it is to work with.

I am going to try a different contact cement.

The Lepage Blue is better suited for bonding laminates to tabletops etc. and is not recommended for polystyene or polyurethane foams.

The Lepage Green is water based non-toxic and is suitable for polystyene and polyurethane foams.

I am not sure what my thick foam is and the fellow at the Plastics store wasn't sure either.

Perhaps Peterh can help out on this one if he's reading this post.

At Boeing we used 3M type 77 (spray) to attach Urethane (solid and foam). Great bond with it

I did try a small test strip with 3M 77 and it seems to be holding OK adhering the vinyl to the 1/2 inch foam

Liquid Nails is a neoprene latex contact adhesive. This might be the best choice for bonding. Just squirt it out and use a squeegee to spread

Kevin,

I ran a bunch of tests on Eco Foam from Home Depot - got samples from the factory and decided not to use it. There is a burlap like scrim on one side that will stick to the wall and then separate from the foam - using 3m 77. It is too soft and any paint I applied would crack. I went with a denser, thinner foam. There are threads and much info on this in the forum. If you want more info I would be glad to share what I found and did.

From a sheer utility & insulation prospective - why paint anyway? (Covering with vinyl for scratch resistance I can understand).

What I do agree with is that if look is important, there are way better materials to paint over that polyethelene. It truly sucks to paint.

If after proper insulation is installed, has anyone tried to use automobile headliner material? Either vinyl or fabric? Seems to me to be an obvious choice, but I've not heard anything about this as an option...

I have gutted my 87 Lil Bigfoot and am having a shop install perforated vinyl headliner material on the walls. I'll let you know how it goes, but it should be an ideal choice for durability.

Talking

Kevin61, that Green contact cement looks like it would be much more pleasant to work with. The Blue stuff had a skull and crossbones on it, (shudder).

Did I understand someone to say that the Ecofoam separates?

I think the green will be the way to go. Hopefully will get some test strips glued up this week.

Someone did mention the Ecofoam may have a fine backing on it that may separate. I've looked and can't see it so will probably glue up some test strips and then see how easily it rips off the wall of the trailer.

Hi - Here are the pictures of the Home Depot Ecfoam

You can see that there is a textured back on it. This separated from the foam when glued - the back stayed on the wall, the foam didn't. The backing is plastic and the glue cannot penetrate. I used 3M 77 spray adhesive.

Next post, paint

The paint was two coats of Kilz primer and two coats of premium latex...

Hope this helps. I did not buy the Ecofoam. If you go ahead with it let me know how it turns out.

I used Weldwood Contact Cement. Get a good mask! I was told this may have been a mistake - I'll have to live with it.
