1. What is the primary purpose of applying a primer before painting
a new drywall surface?
a. To increase the gloss of the finish coat
b. To eliminate the need for surface preparation
c. To seal the surface and promote uniform adhesion and appearance
d. To make the finish coat dry more slowly
Rationale: New drywall and joint-compound areas are porous and can
absorb paint unevenly. Primer seals these differences, improves
adhesion, reduces flashing, and helps the finish coat develop a
consistent appearance.
2. Which surface preparation step is most important before painting
a previously painted wall?
,a. Increasing the paint thickness
b. Cleaning and removing loose, peeling, or failing paint
c. Applying finish paint immediately
d. Adding thinner to the old coating
Rationale: A new coating can only perform as well as the surface
beneath it. Dirt, grease, loose paint, and other contaminants must be
removed so the new coating can properly adhere.
3. What is the primary purpose of sanding a previously painted
surface before recoating?
a. To remove all existing paint
b. To increase the surface's moisture content
c. To smooth imperfections and provide a suitable surface for
adhesion
d. To eliminate the need for primer in every situation
Rationale: Light sanding can remove rough areas, degloss certain
coatings, and create a better mechanical bond for the new coating.
Complete removal of sound paint is generally unnecessary.
4. Which condition is most likely to cause blistering of a paint
coating?
,a. Properly prepared dry wood
b. Correctly primed drywall
c. Moisture trapped beneath or within the coating system
d. A properly applied second finish coat
Rationale: Moisture can create pressure beneath a coating and
interfere with adhesion, resulting in blistering. The underlying
moisture source should be identified and corrected before repainting.
5. What should a contractor generally do when existing paint is
peeling extensively?
a. Apply a heavy coat of finish paint over it
b. Apply a glossy coating without preparation
c. Remove unstable coating, prepare the substrate, and prime as
appropriate
d. Add water to the new paint
Rationale: Peeling paint indicates a coating failure. Painting over
unstable material usually causes the new coating to fail as well, so the
defective material must be removed and the substrate properly
prepared.
6. Which tool is commonly used to remove loose or peeling paint
from a surface?
, a. Caulking gun
b. Paint scraper
c. Drop cloth
d. Paint grid
Rationale: A paint scraper is designed to remove loose, flaking, or
peeling coating material. After scraping, the surface is typically
sanded and otherwise prepared before coating.
7. What is the primary function of painter's masking tape?
a. To increase paint coverage
b. To seal cracks permanently
c. To protect adjacent surfaces and create controlled paint edges
d. To replace surface primer
Rationale: Masking tape protects trim, hardware, glass, and other
adjacent areas from unwanted paint. Proper application and removal
help produce clean, professional edges.
8. Which practice is most appropriate when preparing a greasy
surface for painting?
a. Paint directly over the grease
b. Sand the grease into the substrate
