polyurethane - is it removed by acetone?

[Daniel]

Hi,

Is polyurethane removed by acetone? I've DAGS, and some sites say
acetone will soften poly, others say poly will shed acetone like water.

I managed to remove a hard clear finish by rubbing it with a paper towel
moistened with acetone. Before the removal, spraying some nc lacquer
over the unknown finish caused that finish to lift and wrinkle for the
portions over wood, and did not soften or wrinkle anything for the
portions over metal. Another factor is that portions of the wood may
have been exposed to a tung/urethane varnish, but I did wipe it off
before the varnish got sticky. (yes, I'm in a mess.)

Thanks for any info you may have.

Acetone will dissolve shellac but not do much to poly-
may soften it a bit, but not dissolve it. I have refinished
some poly coated chairs etc with pretty good results
using Parks refinisher. As I recall, it is a combination
of solvents which dissolve several types of coatings. Still
requires some elbow-grease!

Worth a try.

Good luck!

FWIW Back in my school days we used "deft" polyurethane and were warned
not to use "Pledge" with lemon oil in it as it would dissolve the finish.
It did on several projects. Last year I finished some items with a cheap
poly ($12 a gal) and one of my customers who used a lemon oil product to
clean wood work had the same problem. I know that most of the
polyurethane's on the market now are impervious to lemon oil, but you might
try it and see.

Polyurethane is one of the toughest and most durable clear coats on the
market. (Depending on what brand you buy) It helps to be able to identify what
you are dealing with by site and touch of the surface that it has been applied
to. But that comes with experience of being a professional painter and wood
finisher . (30 yrs worth) Lemon and other citrus oils are more of a cleaner
and protector than anything else. Paint stripper works well for taking off all
different kinds of finishes but works better on horizontal surfaces so it can
fester and work it's magic. However stripper has changed over the years
because of all the material regulations and poison control these days. Lacquer
thinner and course steel wool works really well just make sure you take proper
precautions like wearing rubber gloves safety glasses . Make sure you prep
with tape, paper and chemical resists plastic be it will destroy everything
the it touches. You will have to sand after the chemicals dry and evaporate .
If you can't use a sander you will have to hand sand before applying your
choice of finish or
You will know rite away if you didn't remove old paint or finish well enough
when you apply new finish
It takes a lot of patience to be a painter and not everyone can do it and you
have to think 2 or 3 steps ahead. I hope I helped you Daniel.

13 years later Daniel has an answer. Sadly, he was killed when his
garage blew up when he tried heating acetone to make it work better.
Seems he was lacking proper information on its use. He is survived by
his ex-wife, dog, and a polyurethane coated bookcase.

Did he at least get a nice smooth coat on the bookcase?

I felt obliged to observe a moment of silence after reading that.

I think the bookcase was a ruse to throw the DEA off the track of his
acetone purchases.
