Cheap fiberglass
|
I was looking at home made campers on YouTube & there was someone coating his plywood with watered down titebond 3 then covering it with a bed sheet then more watered down titebond. He then painted it. The finish was rough. I can visualize all of it peeling off in a couple of years. I know titebond is a great glue, but this good? Anyone ever done this?

Trouble with using the bed sheet is every morning after you’ve slept in the camper it gets rumpled and you have remake it…

I did an experiment a few years back with it. Used TB3 and bed sheet. Put one piece in a bucket of water to simulate a bait being in the water and the other chunk I left out in the weather to simulate being stored outside.

I started the experiment in August and it ended March. Both failed. Both were fine until the rain and snow hit Case Sent from not here

I use TB3 50/50 as a sanding sealer on wood to be painted. Great stuff. It really is waterproof. I assembled outdoor furniture with it, no paint, 7 years later, still strong. The bedsheet material is the issue with most of these tests; the plastic or cotton sheeting won't stand up to the UV from the sun. Paint it and it should last a long time. I have yet to test 2 oz fiberglass with TB3 and paint. I would guess it to be really tough.
My Dad had cotton duck covered spruce canoes, they went years out in the rain and snow. Lots of paint was the secret.

Sounds like TB3 just isn't very UV resistant. Case were your pieces coated with paint, or was the UV getting to the glue? Did the fabric fail or the glue? Cotton should be pretty UV resistant, Work shirts last years. And people used to dry all their cotton in the sun. Plus cotton sails. -Jove

When I built Passage, I epoxied the decks with a couple rolled on coats of epoxy, then laid 10 oz cloth in Aerobal, made sure it was well coated, painted over it with Wards (at the time) porch and deck paint. 28 years later I saw the boat still on the same coat of paint. I can’t even find Aerobal online to show a link. It was an aviation product as I recall.

Painted with porch and deck. Glue failed. Cloth peeled off.

Bummer. The porch and deck is typically a very good paint. Doing the deck on Passage, it was important to squeegee the aerobal initial coat on the deck through the weave of the cloth. Perhaps there was too much reliance on surface bonding with the sheet. I wonder if glass cloth woulda done better for penetration?

Chief Redelk over on the Duckworks group has used Titebond II for a lot of "off the label" uses. He's used it with various fabrics, and also, thinned, as a primer on bare wood under latex paint. Apparently the key, as it were, for using it as a primer is to wait until the goo is _almost_ set, then slapping on the paint. His boats have lasted well in northern Louisiana, but he stores them under cover, and they only get wet when he uses them.

That's not a typo -- Titebond II. It's cheaper and easier to find in Louisiana than Titebond III. Some other folks over on the DW group have also experimented with using Titebonds in unusual ways. I'd only use it as anything other than glue on a boat I wasn't putting much money and effort into: https://groups.io/g/dwforum/

Arabol is extinct, but pretty much the same stuff is sold by another name. You can get it at Englund's. Rick J told me the particulars a few moths ago, but I've forgotten them. <sigh> Arabol was a pipe lagging goo. A PVA goo, related to Elmer's glue and the Titebonds, made by Bordens.

This may be what the fishing boats are using now: https://www.englundmarine.com/products/deck-adhesive-ga%7CHUM-DAG.html

That’s the stuff! I spelled it wrong. Got the usage in error, too. Thanks for setting it straight, John. It was easy to apply, worked like a champ when properly done. Geez, I haven’t been to Englund’s in years, either. Still use Victorinox steak knives I bought there over forty years ago. At the time, they were 3.95 each so I bought a dozen. But I digress..
