Removing paper backing from old Plexiglas (2023 Update)

[gchigoche]

Hi Bobby,

May you please advise of the brand of laquer thinner to use. I have very large sheets which I intend to use.

Thanks

Godfrey

Brand matters little. In years past, they were all ketone based, MEK, and worked pretty much that same. New air standards have changed the formula and most have soy methyl esters, ethylene glycol and stuff but most are similar. If the OP used a can that was a few years old, the formula has changed.

Exactly! Buy some damn lacquer thinner, try it on a small area and see what happens. It either works or it doesn't. If it crazes the acrylic sheet you then know that it doesn't work. If it doesn't craze it and doesn't remove the paper are you any the worse off?

I usta work at a US govt lab. We hadda lotta plexiglass and some was pretty old. The old paper backing in those days (80s) was near impossible to get off, after a certain age. We had a lotta solvents, etc, and tried 'em all. Stoddard's solvent (wht spirits) worked the best, but still required mucho elbo grease.

Even worse!! ....plain ol' masking tape on stainless steel, baked on for 2 mos in the CA Summer sun. Sorry! No solvents work. Jes a lotta guys with razor blade scrappers, also in the hot CA sun.

I've got some plexiglass from True Value. Now, seems to be covered with a see-thru plastic film cover. Comes right off on a piece that's

2 yrs old. Thank-you, whoever you are! ;)

Naptha softens/dissolves most backing glues for me.

When paper lifts, peel back slowly and repeat till the end. Wipe off excess glue with thinner rag as you go....thank you so much... Cheers John

I'm not gonna dispute John's post, as I do not know what they are doing, now. But, waay back, we had some really old Plexiglass w/ some kinda brn paper protecting the surface.

Couldn't get it off. Tried everything and we hadda buncha choices. This at a govt lab that could get any solvent on the planet. We finally settled on Stodard's (mineral) solvent.

Still, this was many yrs ago. The last sheet of Plexiglass I bought had some sorta "clear" covering. Heck, it's peeling off on its own.

Well read thru everyone's posts I'm having the same problems here's what I learned .... The paper laminate ply is latex in my circumstance no Chem peel and ironic ally, there's no adhesive . the paper/ latex is rolled onto the acrylic she et a creates a static adhesive that shrinks when cool My experiment will be to use a new car buffer pad and plexiglass cleaner as a medium Other than that its taken two people and six hours to manually remove the paper and now the latex .... One has contemplated harri marry while the ot her creates suggestions in the middle of the day ling project one has also considered melting the plexi and latex with carb choke cleaner as a last r esort toward the frustration this causes ... However I think the buffer ple xi cleaner hot water will work

I tried Goo gone ,goof off , WD 40, and other chemicals ,cleaners .NONE worked like just using a pressure washer from harbor freight tools. or just go to a car wash and use the hot wax setting .

The best adhesive remover known to man:

Soaks through paper labels and gets right to the adhesive. If the label is water resistant, just lift a corner and let the fluid seep underneath. Peel back slowly as the adhesive dissolves.

Some water resistant labels can be delaminated. The plastic outer layer can be removed with a pair of tweezers, leaving the paper behind. Soak the paper with the lighter fluid and remove it as the adhesive dissolves.

I have removed literally thousands of labels over time and nothing works better than good old Ronsonol.
