5200 removal

[undersee]

Tried using the search feature but no luck.


Last year put something together using 5200. Now I need to remove a piece. Is there a product anyone has found to loosen up or dissolve 5200? Or is there a technique (aside from sharp knifes, and a multimaster) that works?

Thanks
Lucky

This is exactly why I don't like using 5200. If the boat lasted this long without it, why is it necessary to use it now? You can break wood before 5200 will let go. I am talking about small or local repairs here.
If you are totally rebuilding a bottom and re- engineering the boats bottom construction that's an entirely different and better scenario for using 5200 in my opinion.

I have been working on a heat- blade 5200 removal tool made out of an old, large soldering iron that I have. I had a wedge machined out of a piece of solid square stock with a round mandrel on it's one end that will slide into the hole in the tool where the iron would have gone. I still need to drill and tap holes in the hypotenuse (did I spell that right?) of the wedge to fasten thin, flat pieces of metal bent to the correct angle in order to make a hot putty knife. I've got some old hose reel spring salvaged to try and make the actual knife out of. It's another one of those projects that got back- burnered and stuck away in the back of the garage somewhere. If it works as well as I hope it does, it might make a good paint and varnish removal tool too.

There is a relatively new product ton the market that is supposed to release the bond of 5200. It is called Un-hesive.

It is new, so I don't know of anyone who has tried it. I talked briefly with the developer. He claimed that it leaves no adhesive residue or product reside that would stand in the way of restaining and varnishing.

I am somewhat skeptical...I don't know why. I have no reason to be. They do only sell this in small spray bottles as far as I know. It seems for for releasing a bit of unwanted adhesive than it does for releasing a bedded plank.

Anyway...it's worth a try. www.un-hesive.com

I saw the un-hesive product advertised not too long ago but couldn't remember where I saw it. Possibly Jamestown, maybe in a magazine. My thought was it's not going to release 5200 deep between 2 boards but it would be handy for cleaning up a smear or spooge from a surface or a drip where you didn't want it.

Heck, get some and try it. The stuff may work better than we think.

Bedding wood with 3m5200 rubber is a PERMANENT bond.A router or chisel might release two parts. If you have hardware or small parts bedded with 5200 and screwed down, debonding solvents may help in releasing parts from fiberglass or wood.....................markmcisaacinc.com

"Un-Hesive" is advertised on page 7 in right hand column of the Fall 2009 issue of The Brass Bell.

I just removed a lot of 5200 sealed planks--what a mess. If you have a multimaster or equivalent and can get under the plank that works--usually from the inside of the hull-cut between the plank and the frame. But there were a lot of places I couldn't get to it that way. Danenburg suggests in his book cutting it with wire but I cant see how you would get the wire between planks and frame. He also suggests an electric hot knife. I guess you would remove screws and then work the knife between the plank and frames

Frank,

I even thumbed through the Brass Bell thinking that's where I might have seen Un-Hesive mentioned but I missed it. I was looking in the ad section though.

Al, the blurb is in the same issue that the article about Boat Buzz's most prolific poster is profiled! It's on page 7 on the right hand side in the "Beacon" section. It's not in the ads.

Thanks Frank, I found it. Who's that old man pictured with my beautiful young wife and granddaughter? It would be a good photo if it wasn't for him!

The Un-Hesive looks to be a useful product. Careful, don't spill it in the bilge though.

Don't underestimate the usefulness of a Multi Master. You can use it for many things beyond cutting 5200.

Just spoke with Jake from North Star Products.

http://www.un-hesive.com/index.html

Very nice guy, he explained to me this product has been around for some time but is just starting to make it into the marine world. Apparently floor contractors have been using it to remove laminates along with the adhesive.

Jake was very excited to hear that his product is finding its way into the antique marine market and is mailing me a 32 oz bottle, priority mail with the invoice enclosed to pay upon my satisfaction.

Now there's a guy who stands behind his product!!!!!!!

By Saturday I should have a report on the Un-Hesive posted up here.

BTW the Multi Master is a must have tool. Its amazing all the different things that little machine can do and is in the list of my top 5 favorites.
The rest are in no order:
My antique Walker Turner band saw, Dewalt 18v impact driver, Dewalt orbital sander, and the installed dust collection system,

Stay tuned,
Lucky

Wrote this a few weeks ago but wanted to post it along with a few picks, but can’t find my camera anywhere. Figured I’d post it so my camera would show up right after I’m no longer looking for it.

Last week posted a topic under hull construction asking if anyone knew of a product for removing 5200.

A product was brought to my attention call Un-Hesive.

Spoke with the company representative by the name of Jake, and he instructed me how to use the product along with any tips I should need.

Ordered 32oz worth of product ($45.00) and it arrived priority mail within the next few days.

Following Jakes advice I cranked the heat up in the garage; the product needs a minimum of 73 degrees.

Un-hesive is sprayed on like Windex, and even smells a little like it.

I did everything like Jake said, “spray liberally letting it soak into the wood a minimum of 20 minutes and use a heat gun”.

The main job today was to remove the ¼” plywood on the bottom and 1 very bottom side plank. The side plank was bedded into place last year, and the plywood had a light skim coat where the 5200 oozed out.

So here is my opinion of the product after using all 32oz’s.

It does work, but not like I thought. What the product seamed to do was soften the 5200 releasing the bond between the wood and 5200. It’s not like a paint stripper and will not degrade the integrity of the 5200

Pulled the plywood up first with the help of a heat gun and some well placed pry bars. The plywood came up fairly easy. Next step was the side planking and that was a different story. With the wood being heavily beaded into the chine it was next to impossible. The Un-Hesive did help, but I still needed the multimaster. It took lots of time and my patients were tested.

So the over view is where you need to remove 5200 on the surface, Hell yes it works, but for anything heavily beaded you’ll receive some help but not that much.

So the question of would I buy this product again or recommend it? YES!! But we are still far away form that miracle remover, if it will ever exist.
