1. What is the primary purpose of applying primer to a properly
prepared surface before painting?
A. To eliminate the need for surface preparation
B. To improve adhesion, promote uniform absorption, and provide a
suitable base for the finish coat
C. To make every finish coat waterproof
D. To eliminate the need for multiple finish coats
,Rationale: Primer helps the finish coat adhere to the substrate and
reduces uneven absorption, which can cause flashing or inconsistent
appearance. Certain primers also block stains, seal porous materials,
or improve corrosion resistance. Primer does not replace proper
surface preparation or automatically eliminate the need for multiple
finish coats.
2. Which preparation method is generally appropriate for removing
loose, peeling paint from an ordinary wood surface?
A. Applying a new coat of paint directly over the loose paint
B. Saturating the wood with water
C. Scraping or sanding the loose coating and feathering the remaining
edges
D. Applying a heavy coat of primer over the peeling paint
Rationale: Loose and failing paint must be removed so the new
coating can bond to a sound surface. Feather-sanding the edges of the
remaining coating helps minimize visible ridges. The surface should
then be cleaned, allowed to dry, and primed as appropriate.
Encapsulating loose paint beneath primer does not correct the
underlying adhesion failure.
,3. Which factor is most important when selecting a paint for an
exterior masonry wall?
A. The color of the painter's equipment
B. The brand of the interior wall paint previously used
C. The number of workers on the project
D. The masonry's moisture condition, porosity, and compatibility with
the coating system
Rationale: Masonry coatings must be compatible with the substrate
and its moisture conditions. Porosity affects absorption and coverage,
while trapped moisture can contribute to blistering, peeling, or
coating failure. The coating manufacturer's requirements and the
condition of the masonry should guide product selection.
4. What is the primary function of a paint's binder?
A. To provide the paint's container with corrosion resistance
B. To hold the pigment together and form the continuous film after
application
C. To determine the exact thickness of the brush bristles
D. To prevent all solvents from evaporating
, Rationale: The binder, also called the resin or film-forming
component, holds pigment particles together and forms the coating
film as the paint dries or cures. It strongly influences adhesion,
durability, flexibility, and resistance to environmental conditions.
Pigments provide color and opacity, while solvents or water help with
application and flow.
5. Which tool is most appropriate for producing a smooth finish on a
large, properly prepared interior wall?
A. A stiff wire brush
B. A masonry trowel
C. A suitable paint roller with the correct nap for the wall texture
D. A pointed masonry chisel
Rationale: A properly selected roller distributes paint efficiently over
large wall areas. The nap length should match the surface texture:
smoother surfaces generally require shorter naps, while rougher
surfaces need longer naps to reach recesses. A brush may be used for
cutting in around edges and detailed areas.
6. What should a painter do before applying a new coating over an
existing glossy painted surface?
A. Apply the finish coat immediately
