[papercreters] Re: Paint that has frozen



Dear All,

My advise to use a thinner for a frozen paint was based on my understanding that , in fact the frozen paint is oil based.

The terms acrylic and latex are really interchangeable in the modern context. 
Wikiepedia says"Water-based acrylic paints were subsequently sold as "latex" house paints, although acrylic dispersion uses no latex derived from a rubber tree."

Once acrylic paint has been exposed to air it dries quite quickly.

Once dry, nothing can be done with it.
Wikipaedia "Acrylic artist paints may be thinned with water and used as washes in the manner of watercolor paints, but the washes are not re-hydratable once dry."

"When dry, acrylic paint is generally non-removable from a solid surface. Water or mild solvents do not re-solubilize it, although isopropyl alcohol can lift some fresh paint films off. Toluene and acetone can remove paint films, but they do not lift paint stains very well and are not selective. 

So if the frozen paint is indeed acrylic, it is of no use as a paint.

What does the frozen paint bucket say on the outside about its composition?
 
Regards
Ashok
