Exam Details

The Florida Plaster and Lath Specialty Contractor examination is administered through the Florida Department of Business and Professional Regulation (DBPR) and its construction examination program.

The trade knowledge examination evaluates practical and technical understanding of plastering and lathing work, including materials, tools, installation, building standards, safety, and estimating.

  • License Classification: Certified Plaster and Lath Specialty Contractor.
  • Licensing Authority: Florida DBPR and the Construction Industry Licensing Board.
  • Trade Examination: Plaster and Lath Specialty Contractors Trade Knowledge.
  • Trade Examination Questions: 50 questions.
  • Examination Delivery: Computer-based testing.
  • Examination Format: Open book.
  • Additional Examination: Business and Finance, as applicable to the certification pathway.
  • Trade Content Areas: Eight principal categories covering plastering, lathing, materials, safety, and contractor responsibilities.

The trade examination emphasizes technical knowledge and real-world construction practices. Some questions are based on the designated reference books, while others evaluate knowledge developed through field experience.

Candidates should prepare for questions involving plaster compositions, lath installation, application methods, moisture barriers, equipment, construction codes, workplace safety, and material quantities.

Open Book Test

The Florida Plaster and Lath Specialty Contractor trade examination is an open book test. Candidates may use the reference materials authorized by Florida DBPR for the examination.

Open book testing requires preparation because candidates must recognize the subject of each question, identify the correct reference, and locate technical information efficiently.

Florida's examination rules allow underlining and highlighting in approved reference materials. Handwritten and typewritten notes are not permitted, and movable tabs cannot be used.

References must remain properly bound, and only one copy of each approved reference is permitted in the testing room. Candidates cannot add markings to their references during the examination.

For example, a question concerning plaster coverage or material quantities may require an estimating reference. A question involving scaffold safety may involve OSHA construction standards. Technical questions about lath installation may require an ASTM standard or plastering reference.

Develop familiarity with each approved book's table of contents, index, terminology, and important technical sections.

Practice locating information without reading entire chapters during every question. Organized reference navigation is an important part of effective open book preparation.

ACE supports these study habits through explanations and technical review. The AI tutor is intended for preparation rather than use during the proctored examination.

Licensing Steps

Pursuing a Florida Certified Plaster and Lath Specialty Contractor license involves meeting professional qualifications, completing applicable examinations, and submitting the appropriate certification application.

  1. Understand the classification: Review the authorized scope of plaster and lath specialty contracting in Florida.
  2. Evaluate your experience: Review your qualifying construction experience, trade responsibilities, and supervisory background.
  3. Study the examination outline: Become familiar with the eight Plaster and Lath Trade Knowledge content categories.
  4. Prepare with approved references: Review the designated plastering, estimating, safety, ASTM, and Florida Building Code materials.
  5. Register for examinations: Follow Florida's construction examination registration and authorization procedures.
  6. Complete required testing: Take the applicable trade knowledge and Business and Finance examinations.
  7. Submit your certification application: Complete the appropriate application through Florida DBPR.
  8. Satisfy licensing qualifications: Provide required supporting documents and complete applicable financial responsibility, background screening, and insurance requirements.

Florida also provides certain examination exemption and endorsement pathways for qualifying applicants. Each pathway has separate eligibility conditions.

The ACE free demo introduces educational examination preparation rather than application processing or licensing services.

State Requirements

Florida regulates certified specialty contractors through the Construction Industry Licensing Board under Chapter 489, Florida Statutes.

A Florida Certified Plaster and Lath Specialty Contractor is qualified to coat surfaces with mixtures containing sand or other aggregates, gypsum plaster, Portland cement, quicklime, water, or combinations of these materials to create a permanent coating.

The classification also authorizes lathing work within its defined scope.

This specialized classification is relevant to contractors performing plaster finishes, stucco-related coating work, and associated lath installation.

Florida's licensing framework distinguishes specialty contracting from broader General Contractor, Building Contractor, and Residential Contractor classifications.

Applicants must satisfy an approved professional qualification pathway and meet the state requirements associated with certification.

Florida provides application options for individuals seeking active or inactive certification and for certified contractors qualifying a business.

Understanding the scope of the Plaster and Lath Specialty Contractor license helps candidates connect examination preparation with the responsibilities of operating within an authorized construction specialty.

Materials Science, Lathing Techniques, and Plaster Mixing and Application Techniques collectively account for 54% of the trade examination outline.

These categories deserve substantial study attention because they address the core materials and installation practices involved in plaster and lath contracting.

Understanding Plaster Materials and Mixing Techniques

Plastering performance depends on selecting appropriate materials and understanding how those materials behave during application and curing.

Study gypsum-based plaster, Portland cement plaster, lime-based materials, aggregates, and the role of water in plaster mixtures.

Review how mixture proportions influence consistency, workability, adhesion, and surface quality.

Learn the differences between preparing a plaster base, applying successive coats, and producing the specified finish.

Become familiar with the tools used to mix, transport, apply, and finish plaster materials.

When practicing technical questions, connect material properties with the installation condition described in the problem.

These habits support stronger understanding of the materials science and application subjects evaluated on the examination.

Preparing for Lathing and Surface Installation Questions

Lathing provides the supporting base for many plaster systems, making proper installation important for surface durability and performance.

Review metal lath, supporting materials, fastening practices, furring, and substrate preparation.

Study how lathing systems interact with framing, sheathing, insulation, and moisture-resistant assemblies.

Develop familiarity with ASTM C1063 and the technical requirements for lathing and furring installations.

Practice interpreting questions involving installation sequence, attachment methods, and preparation of different surfaces.

Understanding the relationship between lath installation and plaster application helps candidates connect separate examination subjects into a complete construction process.

How to Study Jobsite Safety and Estimating

Plaster and lath contractors must understand both construction safety and the planning required to manage specialty projects.

For safety preparation, review scaffold requirements, ladder use, fall hazards, material handling, and personal protective equipment.

Study safe operation of mixers, application equipment, and other tools used during plastering operations.

For estimating, practice identifying surface areas, required materials, waste considerations, and labor requirements.

Review how project schedules, material deliveries, installation conditions, and quality checks affect construction operations.

Understanding these responsibilities supports more complete preparation for the trade examination and the practical demands of specialty contracting.
