BIG TIP: Sara's formula for a bold, textural
approach to pastel or oil stick
SARA'S PUMICE BOARD FORMULA:
1 part gesso or acrylic
color** (tinted as you prefer)
1 part extra fine pumice*
1 or 2 parts water (I
replace some of the water w/ matte medium)
Apply with a foam brush,
using 1 to 5 coats, according to preference. Go different directions each coat.
TIP: I prefer Masonite boards, called "shower board", which is
smooth and brown on one side and white on the other. I put 3 to 5 coats of the
mixture on the brown side.
You can also apply this mixture to canvas--I use gallery wrapped canvas for my oil stick paintings--paint the edges, also.
Can be applied to paper for painting pastels--thin with more water. It only takes one or two coats for this to work.
TIP: **I buy my acrylic color from Utrecht
(1-800-223-9132)--used to be colored gesso. It's now called "regular
pigment load artists' color." This is really thick paint--like soft
butter, so you may need the greater amount of water.
TIP: *Pumice I get—J.E. Moser's pumice stone, 2f and
4f. I obtained this from Woodworker's Supply: 1-800-645-9292. Other brands are
ok. I mix equal parts of this for the grit.
TIP: To apply
to paper--make the mixture thin
enough to flow (2-3 parts water). Dampen the back of the paper as well as the
front by misting before you apply the mix.
TIP: To apply to boards,
either canvas or masonite: use the lesser amount of water, depending on your
gesso. Liquitex is runnier.
TIP: You can use white gesso or matte medium, and
tint it before or after application. Disadvantage--it takes a lot of color to
get a medium value, rich tint--probably not as good as straight colored gesso
or acrylic.
