not your typical paint stripper question... please read

Posted by Blaine Whether on April 20, 2008, 12:59 am

I have a project actually requiring the reuse of paint AFTER it has been
stripped with a chemical stripper. The problem I have is that I don't know
how to redissolve the resulting sludge and chips that the stripper produces
back into as close to the original paint as possible. I realize it wouldn't
be perfect, but how can I thin and dissolve the paint stripper sludge?

Thanks,
Blaine

With oil paint, paint thinner or mineral spirits or terpintine, with
Latex alcohol, will do. Or even soapy water with latex

You can add more paint remover to it, but it will NOT be anywhere close
to paint. What on earth
are you doing?

Not looking for paint, although if I can get somewhat close to that it would
be ok. I just need to dissolve the resulting sludge and chips into a
solution. The thinner, the better. Acetone worked wonders at removing and
dissolving paint in the past, but I am now up against paint that acetone
doesn't dissolve. The paint stripper will do it, but always leaves a sludge
and I need this dissolved too.

Since trolls rarely respond to back to a thread, we must assume that you are
serious.

It seems that at one time you removed or softened a finish with acetone and
somehow reused what ever you removed. That finish was most likely lacquer
which I guess you can redisolve and get some sort of useable finish.

OTOH, the stripper that you used really wreaks the paint at a molecular
level. Its full of very nasty stuff that breaks up the polymer bonds
created in the binder. It also contains wax that is used to keep the sludge
from drying out.

So I guess you could distill out the nasty chemicals and then figure out how
to separate out the pigments, re-grind them up really fine, remix in the
proper binders and solvents and then put in what ever other additives are
needed. Its all described here http://en.wikipedia.org/wiki/Paint.

Good luck
