Airbrush: Masks

Masks cover and protect areas not to be painted. Stencils and Friskets are two types of masks. Masking paper can be taped over larger areas.

STENCIL:
A thin sheet of material in which a shape or pattern is cut, through which paint can be applied to the surface below.

Positive Stencil — spray through holes

Negative Stencil — hold pieces on surface and spray

FRISKET:
Frisket films are usually 3-mil clear vinyl with a low tack adhesive on one side, that protect covered areas from overspray.
1. If an area has been painted, allow to completely dry before applying frisket.
2. Burnish frisket to make sure it's flat, with no air bubbles.
3. To improve adhesion of frisket film to canvas, use a fine weave canvas and apply 1-2 coats of Gloss Medium & Varnish over area that is to be covered.
4. Using a sharp razor knife and light pressure, carefully cut frisket to desired shape. Remove unwanted frisket and apply next color.
5. Do not allow frisket or tape to remain on the surface for periods longer than a day.

TAPE:
To achieve straight lines or attach masking materials use Drafting or Scotch^TM tape. It has a low adhesive tack, which will not disturb the dried acrylic paint it is applied over. Follow directions for frisket (above), substituting tape for frisket.

Protecting Delicate Airbrush Areas on Canvas for Masking Procedures
1. Allow sprayed area to fully dry.
2. Use a clean, soft brush or spray application and carefully coat area with Liquitex Gloss Medium & Varnish. Allow to dry.
3. Contine airbrush application over painting surface as needed. Repeat as necessary.
