Is there a way/method for extending the shelf life of Minwax Wood
Putty after the jar has been opened? I know that the small jars only
cost less than $3/per but it sure seems a waste to have to buy a new
jar of each color 4 months after each one has been opened and a little
Thanks in advance....
Open the lid .. blow in a little propane from a torch .. close the lid.
Propane, being heavier than air will sink to the bottom, effectively
keeping the oxygen away from the putty, which needs oxygen to cure/dry.
I don't think it's as much the little bit of air "stored" above the
contents which causes the hardening as it is the pressure differentials
between the inside and outside of the container caused by temperature
and atmospheric pressure changes. Those cause solvent vapor out and air
leakage in through the minute gaps around the lid, which almost never
seals perfectly once its been opened.
Having the contents resting against the seal joint is better, because
it's a lot harder to force liquid through a small leak than solvent
vapors or air, plus the contents will dry in the leak and seal it.
I started storing all my partially used cans of paint upside down about
20 years ago and know they "keep" much better that way.
The last can of "Plastic Wood" I bought had it's can's "label printing"
upside down with instructions to store it lid end down for the reasons
Works for me,
They don't give ingredients on the jar (probably because we ain't
going to eat the stuff). It does say that it contains an ingredient
that causes cancer in California?????? Doesn't cause cancer in any
Anyway, someone in another forum told me to use oil based putty from
The Color Putty Company http://www.colorputty.com/index.html which
they said they had jars three years old that was still pliable.
I will put a little acetone in the Minwax jars and see if I can revive
That is what I did "FIRST". The MSDS only listed two ingredients
which were "Takc" & "Calcium Carbonate". Common sense dictates that
it is made up of a lot more than these two ingredients but they only
chose to list these two.
Thus, the reason for coming here and asking............ Secondly.....

That is cuz they feed rats 5,000 times their body weight in all their tests. So
everything tested causes cancer in CA. They just don't test or publish the
results of testing salmon and healthy stuff. Just exaggerating of course, re
the amount, but you get the idea.
Old post but I was curious and read the safety data sheet as I write a
lot of them. Considering the product as compounded ingredients are
safer and even though I err on the side of caution I would have toned
down the toxicity warnings.
There is stuff that causes cancer in California that is not considered
cancerous any where else plus there are de minimus thresholds not
exceeded by OSHA standards but are exceeded in California which are
ridiculously low. I put the warning on all of the SDS's I write if the
composition has used any amount of chemical on the list even if it might
have evaporated, e.g. 1 percent in a solvent used to coat a film then
evaporated. This satisfies California and keeps away the bounty hunters
looking for something to turn in and collect part of their draconian fines.
