INTRODUCTION
The Florida Stucco Contractor Licensing Examination is a mandatory trade knowledge assessment for
specialty contractors seeking licensure through the Florida Department of Business and Professional
Regulation (DBPR) under the Construction Industry Licensing Board (CILB). This rigorous examination
evaluates a candidate's mastery of Portland cement plaster application, lathing systems, substrate
preparation, moisture management, and safety protocols specific to Florida's unique climate
challenges. The exam consists of 50 multiple-choice questions with a 2-hour and 10-minute time
limit, and candidates must achieve a score of 75% or higher to pass . The examination is open-book,
allowing approved reference materials including the Florida Building Code, OSHA regulations, ASTM
standards, and the Portland Cement Plaster/Stucco Manual . Successful candidates demonstrate
competency in plan reading and estimating (20%), framing (16%), lathing and substrate (14%), EIFS
(10%), cement (10%), plaster (10%), and OSHA safety (20%) . This comprehensive question bank has
been meticulously developed to reflect the current DBPR Stucco Contractor examination blueprint,
providing advanced, scenario-based questions that mirror the code interpretation and field
application challenges contractors face daily. With detailed rationales for every answer choice, this
resource will strengthen your technical reasoning, expose knowledge gaps, and ensure you walk into
the testing center fully prepared to pass on your first attempt.
CORE DOMAINS TESTED
1. Plan Reading and Estimating (20%) – Blueprint interpretation, quantity takeoffs, material
estimation, and cost calculation for stucco systems.
2. Framing (16%) – Structural framing requirements for stucco substrates, stud spacing,
backing, and structural attachment.
3. Lathing and Substrate (14%) – Metal lath installation, fastener spacing, weather-resistive
barriers, and substrate preparation.
4. EIFS (10%) – Exterior Insulation and Finish Systems, synthetic stucco applications, and
moisture management.
5. Cement (10%) – Portland cement properties, mix proportions, admixtures, and curing
requirements.
6. Plaster (10%) – Three-coat and two-coat systems, scratch coat, brown coat, finish coat, and
application techniques.
7. Safety – OSHA (20%) – Fall protection, PPE requirements, scaffolding safety, and hazard
communication.

QUESTIONS 1-200
Q1: A stucco contractor is preparing to apply a three-coat system
over metal lath on a wood-framed wall. The plans specify a minimum
scratch coat thickness. According to ASTM C 926, what is the
minimum thickness for the scratch coat?
A) 1/8 inch
B) 1/4 inch
C) 3/8 inch
D) 1/2 inch
Rationale: The correct answer is B. ASTM C 926 specifies that the
scratch coat over metal lath shall be not less than 1/4 inch thick. This
thickness ensures adequate embedment of the lath and proper keying
for subsequent coats. Option A is too thin and would not provide
adequate coverage. Option C is the minimum for the brown coat.
Option D is excessive and unnecessary for the scratch coat.
Q2: During a stucco inspection, the contractor notices that the weep
screed is installed flush with the foundation. What is the PRIMARY
function of a weep screed in a stucco assembly?
A) To provide a decorative edge at the foundation
B) To allow moisture to drain from behind the stucco system
C) To increase adhesion of the stucco to the foundation
D) To provide a termination point for the metal lath
Rationale: The correct answer is B. Weep screeds are designed to
allow moisture that accumulates behind the stucco system to drain
out, preventing water damage and moisture-related failures. Option
A is incorrect because the primary function is drainage, not
decoration. Option C is incorrect because weep screeds do not
,3
enhance adhesion. Option D is incorrect because weep screeds do
terminate the lath, but the primary function is moisture
management.
Q3: A contractor is installing metal lath over a weather-resistive
barrier on a wood-framed wall. What is the MAXIMUM spacing for
fasteners attaching the lath to vertical studs?
A) 6 inches
B) 16 inches
C) 24 inches
D) 12 inches
Rationale: The correct answer is B. ASTM C 1063 requires that metal
lath be fastened to studs at a maximum spacing of 16 inches on
center. Option A is the spacing for edge fasteners. Option C exceeds
the maximum allowable spacing. Option D is less than the maximum
but not the standard requirement.
Q4: A stucco contractor is mixing Portland cement plaster for a
brown coat. The plans specify a 1:4 cement-to-sand ratio. What does
this ratio represent?
A) 1 part water to 4 parts cement
B) 1 part cement to 4 parts sand by volume
C) 1 part sand to 4 parts cement by weight
D) 1 part cement to 4 parts aggregate by weight
Rationale: The correct answer is B. The standard notation for plaster
mixes is cement-to-sand by volume. A 1:4 mix means 1 part cement to
4 parts sand. Option A is incorrect because water is not part of this
ratio notation. Option C reverses the components. Option D uses
weight instead of volume, which is not the standard notation for
plaster mixes.

Q5: During a stucco application, the contractor notices that the
scratch coat is drying too quickly in the Florida summer heat. Which
admixture can be added to the mix to slow the curing process?
A) Accelerator
B) Retarder
C) Air-entraining agent
D) Water reducer
Rationale: The correct answer is B. Retarders are admixtures that
slow the setting and hardening of cement plaster, which is beneficial
in hot weather to prevent rapid drying and cracking. Option A does
the opposite and speeds up curing. Option C improves freeze-thaw
resistance but does not slow curing. Option D reduces water demand
but does not significantly affect curing time.
Q6: A contractor is estimating materials for a stucco project. The wall
area is 2,000 square feet. The three-coat system requires
approximately how many bags of Portland cement per square foot?
A) 0.02 bags
B) 0.05 bags
C) 0.10 bags
D) 0.20 bags
Rationale: The correct answer is B. A three-coat stucco system
typically requires approximately 0.05 bags of Portland cement per
square foot of wall area. This accounts for the cement content in
scratch, brown, and finish coats. Option A underestimates material
needs. Option C overestimates. Option D significantly overestimates.
Q7: A stucco contractor is installing a control joint in a large stucco
wall. What is the PRIMARY purpose of a control joint?
