Sorry @MichaelD, I missed your original comment.
@Julianna, I just noticed the drips at the 100 mark you mentioned. Really bad outcome but the remedy could have been a simple one: Just don't stand the painting up on end for a while longer. Something to look out for.
Folks, I'm about to try something different as soon as the weather breaks here and varnish my favorite paintings. Here are my raw notes if you can make any sense of them: Some of this may sound familiar to you already.
Varnish method suggested by Elliott, Virgil
1:51:27 / 1:58:50
Here is a method
that's based on Regalres varnish.
Can be purchased from Natural Pigments
They also have Rublev Colours
1094 varnish kit. I purchased 3 kits that I am about to use.
reversible varnish that will not cross-link or yellow over 100 years.
Makes 4 fl. oz.
no need to remove
eventually turn brown if not removed and replaced in 30+ yrs.
MSA varnishes that
are acrylics are soluble in mineral spirits. Golden.
called Soluvar. Acrylic.
Gamvar beads up
on the surface. Too much medium is added to the paint when the
painting was created will cause this. Remedy: Make sure that
the surface is perfectly clean and dry when you put the varnish on.
To make sure that it is clean and dry, take a very soft cotton cloth
like underwear, moisten it with distilled water, very slightly, not
much water, wipe the whole surface of the painting with that to
remove all of the water-soluble dirt that may have accumulated on the
surface of the painting, give it a day or two to completely dry, no
water should be on the surface or in the paint. Repeat the cloth
process with Gamsol OMS. Very lightly and gently. If the paint is
six months old or older, the paint will not come off with the Gamsol
OMS which is a mild solvent. This will take off all the oils from
somebody's hands that may have touched it or anything that didn't
come off with the water. Let that evaporate for a day or two. Now
it is ready for the Gamvar varnish and it won't bead up. They have a
Satin, Matte, and Gloss version.
Don't ever use
Matte varnish because the matting agent causes cloudiness. I
always use the Gloss version because if you have dark passages in
your paintings, especially dark transparent passages with glazes, the
matting agent that they put in there causes a cloudiness and destroys
the depth of your darkest passages.
The gloss must be
reduced so that it is not overly reflective. Have the painting
lay flat when you put on the varnish. Apply the varnish with a hog
bristle brush about 6 or 7 inches wide. Have several more handy, 3
or 4. Use the first one to put on the first layer evenly without any
missed spots. While that first layer is still wet, grab another
brush that has no varnish on it and go over it and set the brush
aside. Grab another clean brush and go over it again. Now I have
made the layer of varnish as thin as possible. The thinner it is the
less glossy it will be. The varnish layer needs to be thin, not
thick. You can do this over and over again even after this until the
varnish is dry.
Cleaning method for
just a dusty painting is as follows:
