QUESTION 1
Which of the following best defines the scope of work for a C-33
Painting and Decorating contractor in California?
A) Application of paint, varnish, and other finishes to interior and
exterior surfaces, including drywall installation
B) Application of paints, varnishes, and other finishes to buildings and
structures, including surface preparation, and the hanging of wallpaper,
but excluding drywall installation
C) Application of coatings to buildings and structures, including
asbestos abatement and lead remediation
D) All types of surface preparation and coating application, including
structural steel fireproofing
Answer: B
Explanation: The C-33 classification specifically covers the application of
paints, varnishes, and other finishes to buildings and structures. This
includes surface preparation and wallpaper hanging. Drywall
installation is classified under C-9 (Drywall) and is explicitly excluded
,2|Page
from the C-33 scope. Asbestos abatement and lead remediation require
separate certifications and are not automatically included in the C-33
license.
QUESTION 2
Under California Business and Professions Code Section 7159, which of
the following is a required element in a home improvement contract
for painting services exceeding $500?
A) The contractor's business license number only
B) A description of the work to be done, including materials and
approximate quantities
C) A clause allowing the contractor to increase the price for any
unforeseen conditions
D) The contractor's Social Security number for background verification
Answer: B
Explanation: Section 7159 mandates that home improvement contracts
include a detailed description of the work, materials, and approximate
quantities. The contractor's CSLB license number, not a business license
number, is required. Price increases for unforeseen conditions must be
handled through change orders, not blanket clauses. Social Security
numbers are not required in contracts.
QUESTION 3

A C-33 contractor is preparing a exterior wood surface for repainting.
The existing paint is peeling extensively. Which preparation method is
considered the minimum industry standard for this situation?
A) Power washing only to remove loose paint
B) Scraping and sanding all loose and failing paint, feathering edges,
and cleaning the surface
C) Chemical stripping of all existing paint down to bare wood
D) Applying a bonding primer directly over the peeling paint
Answer: B
Explanation: Industry standards and manufacturer specifications
require that loose and failing paint be removed by scraping and
sanding. Feathering the edges creates a smooth transition for the new
coating. Power washing alone does not remove adhered paint and can
force water behind the paint film. Chemical stripping is not always
necessary and is a more aggressive, costly method. Applying primer
over peeling paint does not address the underlying adhesion failure.
QUESTION 4
Which of the following statements regarding lead-safe work practices in
California is correct for a C-33 contractor?
A) Lead-safe practices are only required when the building was
constructed before 1960
B) The contractor must be certified by the California Department of
Public Health (CDPH) for all lead-related work, including minor repairs
, 4|Page
C) For any disturbance of lead-based paint in residential, public, or
commercial buildings constructed before 1978, the contractor must be
a certified lead-safe renovator
D) Lead-safe practices are optional if the contractor uses encapsulants
Answer: C
Explanation: Federal EPA Renovation, Repair, and Painting (RRP) rules
apply to pre-1978 housing and child-occupied facilities. California law
requires CDPH certification for lead-based paint activities such as
abatement, but for renovation and repair that disturbs less than 6
square feet interior or 20 square feet exterior, the contractor must be a
certified renovator and the firm must be certified. The threshold is 1978,
not 1960. Encapsulation is an abatement method that also requires
proper training and certification.
QUESTION 5
When calculating the amount of paint required for a project, what is
the significance of "dry film thickness" (DFT) versus "wet film thickness"
(WFT)?
A) DFT is always less than WFT due to the evaporation of volatile
organic compounds (VOCs)
B) WFT is the thickness measured after drying, and DFT is measured
immediately after application
C) The two are identical for water-based paints but differ for oil-based
paints
