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.
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.
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.
Pursuing a Florida Certified Plaster and Lath Specialty Contractor license involves meeting professional qualifications, completing applicable examinations, and submitting the appropriate certification application.
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.
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.
The following references are identified for the Florida Plaster and Lath Contractor trade examination under the 2026 reference list.
The examination also identifies two additional resources for study only:
These two additional study references are not authorized for use inside the trade examination room.
The Florida Plaster and Lath Specialty Contractor Trade Knowledge examination evaluates eight principal subject categories.
Introduction to Plaster and Lath – 9.5%: Review the development of plastering and lathing methods, common materials, and differences among gypsum plaster, Portland cement plaster, and quicklime-based materials.
Materials Science – 18%: Study plaster compositions, aggregate properties, types of lath, material selection, and how ingredients affect plaster performance.
Tools and Equipment – 9.5%: Review plastering tools, mixing equipment, application equipment, maintenance procedures, and safe equipment use.
Lathing Techniques – 18%: Study lath installation on different surfaces, preparation of plaster bases, fastening methods, and coordination with insulation and moisture barrier systems.
Plaster Mixing and Application Techniques – 18%: Review plaster proportions, mixing procedures, hand application, machine application, textures, finishing methods, and restoration techniques.
Building Codes and Standards – 9%: Study relevant construction codes, fire resistance, sound control, energy efficiency, and technical requirements for plastering and lathing.
Safety Practices – 9%: Review personal protective equipment, material handling, waste disposal, scaffold safety, and ladder safety.
Project Management and Estimation – 9%: Study material estimating, labor costs, project scheduling, quality control, and the coordination of plaster and lath projects.
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.
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.
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.
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.
