Re: [BKARTS] what a devil to clean....



Jet:

Something that has worked for me with PVAs is to soak brushes in isopropyl
alcohol - a usual ingredient in the liquid PVA adhesives.

Isopropyl alcohol will act as a jellification agent, not a solvent.
The alcohol causes the PVA to turn into a colorless jell that may be
squeezed out &/or wiped out with a towel. Any remnants will revert to white
crumbs upon contact with water. They may be pulled out with a wire bristle
brush or other tools.

Isopropyl alcohol is easily found in drug stores and places like Wal-Mart,
where it is shelved as a rubbing alcohol. Typical concentrations run from
about 70% to 90%. I like the higher concentration. I just paid $2 for a
quart of the 90% concentration at Wal-Mart.

Brushes with dried adhesives may soak in the alcohol for as long as is
necessary. I use a screw-top, tall plastic jar. The alcohol should have no
effect on the brushes themselves.

Subject: what a devil to clean....


    As a consequence of a suggestion of someone on this list, I have been
using the polyvinyl acetate monomer adhesive Promacto A-1023 for certain
jobs.  It has some excellent qualities: fast set and high tack, which
make it very useful for stubborn leather turn-ins and stiff bookcloth.
    But how to clean the brushes?  The cold water suggested on the label
isn't working for me;  it looks like the brush has been dipped in
rapidly and terminally solidifying cottage cheese.
    Reminds me of the limerick beginning, "There was a young man from
Racine" and ending "But O what a devil to clean."
What's in between is not for polite ears.
