Breaking free 5200

[corob]

I'm fixing broken chine bolts on a Chris Sportsman. Someone loved the 5200 so much they glued the planks to frames,battan and even to each other! It's great work! Wedges and heat works slowly and painfully. Any slick tricks? or should I just keep making it up as I go along?

IF!! you can slip a sharp knife into the gap, very thin blade, you might be able to do a little cutting to help things along. Also 3M does not recommend 5200 for teak decks because some teak treatments soften it. Good solid caulk of any sort is painful to make let go.

I have had good sucess with taking an old hack saw blade and sharpening it like a long knife. Work it back and forth through the goop and it cuts it quite easily. A wire brush will remove the last stubborn traces after you get things apart should you need clean wood.

[Mike Vogdes]

If you can sneak a piano wire or guitar string between the pieces you will be able to saw right thru.

Never tried this...but I have to think it would work:

I'd use the hot wire concept, but wrap the wires around some nice dowels as handles and clip on the power supply and cut away.

I've had some success heating a putty knife with a propane torch as I pushed it through the caulk. I had the torch on low and a hose nearby! You could also probably use a heat gun.

Ah yes, many brains are better than one! Great ideas, I'll let you know.

I thought this forum had experts on it?!? :confused:

remove uncured 5200 from your hands, tools, steering wheel of your car,and your forehead where you scratched it, :D ect with silicon spray.

remove cured 5200 from fiberglass with a libral spraying of silicon spray. It softens it up allowing use of razors to scrape it away.

[kulas44]

silicon ??? and then paint it with what?

[corob]

Ah yes! as usual ignorance is my best tool! A trip to the music store for piano wire drill out some dowels for handles, some fumbling and what da ya know? Wooden wedges and heat gun got 'er done. Never tried silacon spray, next plank. Thank you all, Corey

To add to Kulas, do you mean silicon as in sand? or perhaps silicone? as is a comon spray lubrication.

Good luck trying to get anything to stick to a surface that has a silicone coating.

Instead of either of the above, clean your 5200 from unwanted places with plain old mineral spirits, or a gas rag if you must.

[Bob Smalser]

Kulas is being subtle.

Silicone oil in large quantities is guarandamteed to prevent any kind of paint or epoxy from sticking to any surface contaminated with it.

Cleans off painted surfaces satisfactorily with a whole lot of frustrating work but will give you fish-eyed finishes forever if you get very much of it on bare wood.

How do you know you got it all? When the next recoat no longer fisheyes on you. Otherwise you cuss, scrape, clean, sand and try again.

Careful using very much of it to lubricate your machine tables...if you're puzzled occasionally by that first coat of sealer that won't set up, you now have a suspect. ;)

The stuff is called debond. No guarantees. But its supposed to break down 5200 and make it easier for you to pull your substrates apart.

I'm sure the guys at Jamestown, would love your product analysis, as this is new and "still being tested"

Sawdust, yer links no go. However, if anyone is just trying to separate parts attached with 5200, use a guitar string (the "E" string). Thats basically the same as what the windshield installer uses at the dealership I work at, cept ne caint play a lick on his geetar!

[RiverRat]

I haven't been here since posting and they replys after my post brough a heart gaffaw!

Silicon spray as sold by Home Depot in a spray can.

Need to repaint? then wipe the surface with acetone.

Where are the pros? not here!

[N. Scheuer]

'No pros"? Maybe

We've sure got one heckuva "know-it-all", thoiugh.

Bob Smalser warns against using too much silicone to lubricate machine tables. Good advice. My advice would be not to use any silicone to lubricate machine tables. I have always used straight kerosene to clean them followed by Butcher's brand wax (my preference as it goes on thin and stays) and buff it out. Sorry about straying from the thread.
Re: 5200- piano wire, wedges, brute force, patience, and a cold six pack seem to work best for me.

When you get fisheyes in your paint add some FEE (Fish Eye Eliminator) it is available from automotive paint suppliers, a few drops of this stuff mixed in with the paint works wonders.
