 c. Paint Mixing. Paints shall not be used until they are thoroughly mixed. Improper mixing is considered
to be one of the principal reasons for poor paint performance. Tinting pastes, if used, must be mixed in a
similar manner before they are added to the paint. Pastes shall be measured carefully, and stirred in until
no streaking occurs and the desired color is obtained.
(1) Mixing Procedures. Mechanical paint agitators (shakers) shall be used whenever possible. If a
shaker is not available, the paint must be stirred until all lumps, cakes, and sediments are completely
dispersed. Stirring should be done in accordance with the following procedures:
(a) Open the paint can. If a skin has formed on the paint surface, it should be carefully removed
and properly discarded in accordance with specific waste disposal policies.
(b) Pour the top 2/3 of the paint into another can.
(c) Stir the pigment and liquid left in the first can until the paint is smooth; a paint mixing
attachment for use with an electric or pneumatic drill is suitable. See section 2 for applicable safety
precautions.
(d) Gradually, add contents of the second can to the first can, continuing to stir.
(e) Continue to mix by pouring the paint back and forth from one can to the other (boxing) until
uniformly smooth.
(2) Paint Straining. Strain the paint through a wire screen or cheesecloth to remove any particles or
skins that remain undissolved after stirring.
permitted, each coat should be tinted differently to aid in determining proper application and to ensure
complete coverage. Sufficient time must be allowed for each coat to dry thoroughly before top coating or
subjecting the painted surface to service conditions such as immersion.
application of paints are described in Sections 5, 6, and 7.
NOTE
Before starting any painting job, ensure that surface preparation has been completed as directed
in Section 3. Apply the first coat of paint as soon as practicable after surface preparation has been
accomplished.
5 7. Paintbrush Techniques. The techniques used in the application of paint with a brush are as follows:
a. Painting Procedures. Start major work on overhead areas first, and then work downward. Begin
painting at a corner or some other logical vertical division. Cover only the areas, which can be easily
reached without moving ladders. Work downward, painting progressive sections to the deck level then
start at the top of the adjacent area and work down again. Paint trim, doors, or similar areas after
bulkheads and other major surfaces are completed.
b. Coating Application. Dip the brush into the paint up to 1/2 the bristle length Withdraw the brush and
tap it against the inside of the bucket to remove excess paint. Hold the brush at an angle of 45 to the
work. Make several light strokes in the areas to be painted. This will transfer much of the paint to the
surface. Then spread the paint evenly and uniformly. Do not bear down on the brush.
(1) When one section of the surface is painted, adjacent areas should be painted so that the brush
strokes are completed by sweeping the brush into the wet edge of the paint previously applied. This helps
eliminate lap marks and provides a more even coating.
