					PAINTING: ACRYLIC EXERCISE                           NAME:_____________________


LESSON FOCUS:

This lesson focuses on working with acrylic paints using a variety of techniques.


VOCABULARY:

Acrylic: A clear plastic used as a medium for pigments. Acrylic paints can be used on
almost any painting surface without painting a ground first. They dry quickly in glossy or
matte finishes.
Crosshatching: In crosshatching, lines and strokes or color are criss-crossed on top of
one another to create a fine mesh of color or tone.
Drybrush: In the drybrush technique, a small amount of thick color is picked up on a
brush which is skimmed lightly over a dry painting surface. The paint catches on the
raised “tooth” of the paper or canvas and leaves tiny speckels of the ground, or the
underlying color, showing through.
Frottage: The word “frottage” is derived from the French verb frotter, meaning to rub.
The term is associated most often with rubbing on paper over a textured surface so that
the underlying pattern comes through. It is the technique of creating a rich, irregular
texture in wet or semi-wet paint by rubbing a sheet of non-absorbent paper onto an area
of flat, opaque color. When the paper is peeled away it drags at the paint, leaving a rough,
mottled surface.
Glazing: It is a system in which thin, transparent washes of color are laid on successive
layers of dried colors, such as many sheets of colored tissue paper.
Medium: (1) Any material used to create a work of art; plural form, media. (2) In
painting, a liquid added to the paint that makes it easier to manipulate.
Scraffito: The word “scraffito” is derived from the Italian word graffiare, meaning “to
scratch”, and refers to a method of scratching or scraping through a layer of paint to
expose the color or colors underneath.
Scumbling: Scumbling is the rough application of a dry, light, semi-opaque color over a
darker layer of dry, opaque paint. The scumbled layer is applied thinly, creating a delicate
“veil” of color which partially obscures the underlying color.


PROCEDURE:

      Divide a 12”x 18” sheet of oak tag into 6 equal squares that measure 6”x 6” each.
      Using the following techniques, fill in each square:
          o Crosshatching
                   Choose two colors to work with
                   Beginning at one end of the square paint using the crosshatching
                      technique.
                      Gradually add the second color and blend into it using the
                       crosshatching technique.
           o   Drybrush
                   Load your brush with paint and adding no water, drag your brush
                       across the square, allowing the texture of the paper to show
                       through.
           o   Frottage
                   Cover your square with a thick layer of paint.
                   While it is still wet, lay a scrap piece of paper on top of the wet
                       paint and rub.
                   Peel the paper off to remove some of the wet paint to create
                       texture.
           o   Glazing
                   Cover your square with a thin layer of paint (one color) and let dry.
                   Choose another color and apply thinly on top of the first color and
                       let dry.
                   Choose a third color and apply thinly on top of the 2nd color and let
                       dry.
           o   Scraffito
                   Cover your square with a layer of paint and let dry.
                   Choose another color and apply on top of the first layer.
                   While wet, use a comb, the end of a paintbrush, and/or a palette
                       knife to scrape off the some of the second layer allowing the first
                       color to show through.
           o   Scumbling
                   Cover your square with a layer of dark paint and let dry.
                   Using a lighter color and a brush, apply the second layer in a
                       circular motion allowing some of the color from the first layer of
                       paint to show through

MATERIALS:

      12”x 18” oak tag
      Pencil and ruler
      Acrylic paints (assorted colors)
      Brushes, palette knives, combs
      Water container and paper towels



REMINDERS:

A paint that turns into plastic:

Acrylic paints are agglutinated pigments in a polyvinyl emulsion that dry as a result of
the evaporation of water they contain forming an elastic, transparent, and very resistant
film, with a consistency similar to plastic. After it dries, acrylic paint becomes more
flexible.

YOU MUST SCRUB YOUR PALETTE AND WASH YOUR PAINTBRUSHES
THOROUGHLY!!! FAILURE TO DO SO WILL RESULT IN BRUSHES AND
PALETTES THAT MUST BE DISCARDED!!!!
