CLAYART Digest - 1 Apr 2003 to 2 Apr 2003 (#2003-93)what is the best way to
apply covercoat to an 8.5" x 11" piece of decal paper? I tried pulling a
glob of it over the paper with a credit card but ended up smudging some of
the print (from a laser printer). tried a brush, but the covercoat is so
thick. also, mineral spirits didn't dissolve it off my brush. I'm hesitant
to try screening covercoat through blank screen since it doesn't seem to
clean up very easily. any help y'all could give is much appreciated.

The covercoat I have used is cleaned with lacqure thinner. Rubber gloves
are used to clean outside (vapors) using a stack of 6 -10 sheets of
newspaper under the screen. Layers of paper are removed as they need to
be to have a fresh layer as the covercoat and lacquer thinner are
blotted off. Clean the screen when you finish printing and it will take
less than 5 min. and you do not want to let the covercoat sit awhile and
harden. You should be able to get a 16 x18 screen made for less than $20.
I have 2 sizes of screens (for full size paper @ 19 x 25" and half that.
The screens I have now have been used 15+ years. I usually block out the
screen with packing tape and newsprint to the size area to covercoat.
The best thickness is laid with a 90 mesh monofiliment screen and works
as well with an old worn squegee as a new sharp one. Fiber dia.
determined the print layer thickness and finer meshes make a thin layer
that tears and thicker layers can trash the print. Printing is off
contact from the paper with 1/4" spacer set to hold the frame above the
it. If you are going to do many decals, use a vacume table. Mail me off
list and I will send you plans to build one for less than $30. if you
already have a shop vac or cannister style vacume cleaner. Neither
vacume is changed so you can disconnect it for normal use. Multi color
registration also works best with a vacume table. The drawing also has
the pulley system and water bottle counter weight I use to hold up the
screen while I print.

Hello Ben,
Traditionally, cover coat is applied by screening through an open screen.....do yourself a favor, and go to the art supply store, and by some Krylon (or other brand) spray varnish. This can work just as well. First coat....very light, let it dry....second and third coats can be a little more liberal....if the paper is saturated, the inks will run.
Good Luck,
Andre

There are a few different covercoats out there. Cerdec supplies a couple of
different types. Their newer one doesn't dry in the screen as fast as the
older one but they are both sort of hard to work with. Judging by your
letter you don't have much experience with screenprinting and that is
definately the only way to apply these covercoats. I saw a letter from
Andre that suggests you use the Krylon spray. That normally wouldn't be as
good as the screened covercoats if you were doing a large number of decals
but if you are only experimenting with it and you don't have any
screenprinting experience, then the Krylon is the best route.
