Nevada Lathing and Plastering Contractor (C-17) Exam Book Package

Prepare for the Nevada Lathing and Plastering Contractor (C-17) examination with a focused study package built around the core trade knowledge associated with lath installation, plastering, gypsum systems, construction safety, surface preparation, materials, finishing, and jobsite practices. This package includes Plastering Skills, 1984, Code of Federal Regulations - 29 CFR Part 1926 (OSHA), and Gypsum Construction Handbook, 7th edition.

The Nevada C-17 classification covers lathing and plastering work. Candidates should understand both the installation of lath and other plaster-supporting bases and the application of plaster materials over properly prepared surfaces. Preparation should include materials, fastening methods, supports, substrates, plaster coats, mixing, application, curing, finishing, gypsum construction, safety, tools, and practical field procedures.

The Nevada C-17 examination is a closed-book test. The books in this package are study references and are not allowed inside the examination room. Candidates should therefore use the references to build knowledge and recall before test day rather than relying on book navigation during the exam.

Plastering Skills supports preparation involving plaster materials, mixing, application, lath, bases, tools, finishes, and traditional plastering techniques. Gypsum Construction Handbook, 7th edition expands preparation into gypsum systems, wall and ceiling assemblies, framing, gypsum board, finishing, fire-resistance concepts, and related installation practices. OSHA 29 CFR Part 1926 supports construction-safety preparation involving ladders, scaffolds, fall protection, tools, personal protective equipment, material handling, and other jobsite hazards.

Because this is a closed-book examination, candidates should focus on understanding how lathing and plastering systems are actually assembled and installed. Repeated practice questions, active recall, terminology review, and scenario-based study can help turn information from the books into knowledge that can be applied without direct reference access.

Exam Details

The Nevada Lathing and Plastering Contractor (C-17) trade examination evaluates knowledge associated with lath installation, plastering, gypsum systems, trade materials, tools, construction methods, and safety. Candidates should prepare to apply practical field knowledge rather than depend on reference searches during testing.

The C-17 classification includes both lathing and plastering. Lathing involves selecting and applying wood lath, metal lath, and other materials designed to provide a base or key for plaster coatings. It can also involve supporting components used with fireproof lath and solid plaster partitions.

Plastering involves coating surfaces with plaster materials and installing the lath or other base needed to support the plaster. Candidates should understand the relationship between the substrate, lath or base, plaster mixture, coat sequence, application method, curing, and final finish.

Preparation should include traditional plaster systems as well as gypsum-related construction concepts. Candidates should understand how plaster and gypsum assemblies are supported, attached, finished, and protected and how improper preparation or installation can affect the finished work.

Safety is another important study area. Lathing and plastering frequently involve elevated work, scaffolds, ladders, tools, material handling, mixing equipment, and overhead installation. OSHA study should be approached as practical jobsite knowledge rather than isolated regulations.

Closed Book Test

The Nevada Lathing and Plastering Contractor (C-17) examination is a closed-book test.

The following references are included for study and are not allowed inside the examination room:

• Plastering Skills, 1984
• Code of Federal Regulations - 29 CFR Part 1926 (OSHA)
• Gypsum Construction Handbook, 7th edition

The closed-book format makes active study especially important. Candidates should avoid preparing by simply reading and highlighting pages. Instead, study a topic and then attempt to explain it, calculate it, identify the correct procedure, or answer practice questions without reopening the book.

For example, after reviewing lath installation, close the reference and describe the purpose of the lath, how it supports plaster, what installation problems can occur, and why correct attachment matters. After studying plaster application, explain the purpose of different coats and how surface preparation affects adhesion.

For safety topics, work through jobsite scenarios. Consider how a worker should approach scaffold use, ladder access, personal protective equipment, overhead work, material handling, and tool safety. This style of preparation can make OSHA information easier to retain than memorizing isolated sections.

Licensing Steps

The Nevada C-17 trade examination is one part of the contractor licensing process. Applicants must complete the applicable licensing requirements in addition to studying for the trade exam.

1. Confirm the C-17 classification. Determine that the work the business intends to perform falls within Nevada's Lathing and Plastering classification.
2. Identify the qualifying individual. The contractor license application must designate the individual who provides the applicable trade qualification.
3. Prepare qualifying experience documentation. Organize work history demonstrating applicable experience in lathing, plastering, gypsum-related systems, or other work relevant to the requested classification.
4. Complete the Nevada contractor license application. Provide the required business, qualifying individual, experience, financial, and supporting information.
5. Submit the application for review. The application and qualifying experience must be reviewed before examination eligibility is established.
6. Receive examination eligibility. Once authorization is issued, the qualifying individual can proceed with scheduling the applicable examination.
7. Prepare for the C-17 trade examination. Study lath, plaster, gypsum construction, tools, installation methods, finishing, and OSHA safety.
8. Prepare for Business and Law. Nevada contractor applicants are also subject to the applicable Business and Law examination requirement unless an authorized waiver applies.
9. Complete applicable examinations. Satisfy the examinations required for the contractor license application.
10. Complete remaining licensing requirements. Finish all other applicable requirements before the Nevada contractor license is issued.

State Requirements

Nevada recognizes C-17 Lathing and Plastering as a specialty contractor classification. A C-17 license allows qualified contractors to perform the work authorized within the lathing and plastering scope.

Lathing work includes the selection and application of wood and metal lath and other products manufactured to provide a key or suction base that supports plaster coatings. The scope also includes certain supporting materials associated with fireproof lath and solid plaster partitions.

Plastering work includes coating surfaces with plaster made from materials such as sand, cement, quicklime, hydrated lime, and water, along with installation of the lath or other base supporting the plaster.

Candidates should therefore understand the complete plaster system rather than only the final finish coat. Substrate preparation, lath selection and attachment, plaster materials, coat sequence, curing, finishing, and protection all contribute to successful work.

The Nevada contractor licensing process also includes requirements beyond passing the C-17 trade examination. Applicants must satisfy the applicable experience, application, business, financial, examination, and licensing requirements before a contractor license is issued.

Test Information and Study Materials

A strong Nevada C-17 study plan should divide preparation into lathing, plastering, gypsum systems, tools and materials, surface preparation, finishing, and construction safety. Each subject should be studied until the candidate can explain the correct procedure without looking at the book.

Lathing preparation should include the purpose of lath, common lath materials, attachment methods, supports, bases, framing relationships, and how lath provides a suitable surface for plaster. Candidates should understand why proper fastening and placement are important to the finished system.

Plaster Materials should include the basic materials used in plaster mixtures and the way those materials affect workability, strength, adhesion, and finishing. Candidates should understand the role of cementitious materials, lime, sand, and water in traditional plaster work.

Surface Preparation should receive regular attention. Plaster performance depends on the condition of the base and the way the surface is prepared. Candidates should understand when lath or another base is required, how contaminants can affect adhesion, and why correct preparation is necessary before plaster application.

Plaster Application should include coat sequence, thickness concepts, application methods, screeding, leveling, floating, finishing, and the purpose of creating a proper bond between layers. Candidates should understand the difference between preparing a base coat and creating a finished surface.

Curing is also important. Cement-based plaster needs proper curing conditions so the material can develop the intended performance. Candidates should understand how temperature, wind, moisture, and premature drying can affect plaster.

Gypsum Construction should include gypsum board, wall systems, ceiling assemblies, framing, attachment, joints, finishing, and related materials. Candidates should understand how gypsum construction differs from traditional plastering while recognizing where the two trades and systems may overlap.

Fire-Resistance Concepts should be reviewed through the Gypsum Construction Handbook. Candidates should understand that wall and ceiling assemblies can have specific construction requirements and that altering materials, attachment methods, or assembly details can affect performance.

Tools and Equipment should include the common hand tools and equipment used for lathing, plastering, mixing, finishing, cutting, fastening, and measuring. Study not only the name of each tool but also the purpose it serves and how it is used safely.

Scaffolds and Ladders deserve dedicated safety review because lathing and plastering frequently take place on walls and ceilings above floor level. Candidates should understand basic access and fall-prevention principles and recognize unsafe work conditions.

Personal Protective Equipment should be studied in relation to actual trade tasks. Eye protection, respiratory protection where applicable, gloves, protective footwear, and other equipment can be important when cutting materials, mixing products, using tools, or working around dust and debris.

Material Handling should include safe movement and storage of plaster materials, gypsum products, lath, tools, and equipment. Candidates should understand that poor storage or handling can damage materials before installation and create jobsite hazards.

Active recall is especially valuable for this closed-book examination. After reviewing a chapter, close the book and write down the major steps in the process. If you cannot explain the sequence or purpose of a step, return to the reference and review it again.

Practice questions should be used to diagnose weak areas. If plastering-material questions are difficult, return to Plastering Skills. If wall and ceiling assembly questions are challenging, spend more time with the Gypsum Construction Handbook. If safety questions are weak, increase OSHA review.

Scenario-based study can help candidates connect technical information to field work. Ask what could happen if lath is improperly supported, if a surface is not prepared correctly, if plaster dries too rapidly, or if a scaffold is used improperly. Understanding cause and effect makes trade concepts easier to remember.

A balanced schedule might alternate between plastering, gypsum construction, and safety. Candidates can then complete mixed practice sessions that combine all three subjects. As test day approaches, more study should be completed without the references open to simulate the closed-book environment.
