Oil-Based Pigments, Continued
Substrates
(Continued)
MASONITE: Masonite is a wood fiber pressed board commonly available in
hardware stores. Use untempered masonite. Tempered masonite contains oil
providing an unsuitable foundation on which oil-based paints cannot adhere.
There are two sides to a masonite board. One side of masonite is smooth and
the other side of masonite has a wire mesh texture. Select the side of
masonite textured to suit your needs. Large masonite panels may need
stretchers to prevent warping and buckling. Size masonite with rabbitskin
glue before applying a gesso ground.
WOOD PANELS: Wood panels are surfaces to paint on made from wood.
Size and ground wood panel boards as you would masonite.
METAL: Sometimes you may have to paint on metal surfaces. Lightly
abrade the surface with a fine grade steel wool before priming. Oil-based
pigments painted over metal will take longer to dry than over canvas or
wood.
Lacquer-based
pigment
Lacquer-based paints are paints suspended in lacquer solvent. They are
common paints available as household or shipboard cans and pressurized cans
of paint. If the only paint available is lacquer-based paint, be sure to clean
your brushes immediately after use with lacquer thinner or mineral spirits.
Remove the solvent residue by washing brushes in mild soap and water.
Enamel-based
pigment
Enamel-based paints are also common household or shipboard paints.
Enamel paints are available in cans and pressurized cans. If enamel-based
paints are the only paint available to you, be sure to throughly clean the
brushes in mineral spirits before washing them in mild soap and water.
Lacquer-and
enamel-based
pigments
If you must use lacquer- and enamel-based pigments on the same project, do
not apply lacquer-based paint over an enamel paint. The lacquer-based paint
curdles enamel-based paint and may immediately peel it from the substrate.
