Exam Details

The Arizona R-36 Plastering residential contractor exam is administered through PSI for the Arizona Registrar of Contractors. The trade exam contains 30 questions, and candidates are allowed 75 minutes to complete the test. The minimum passing score is 70%.

The Arizona R-36 Plastering exam uses the same trade examination content as the commercial C-36 Plastering and residential / commercial CR-36 Plastering classifications. Candidates should select the license classification that matches the work they plan to perform and follow the Arizona Registrar of Contractors licensing process for that classification.

The exam is focused on plastering trade knowledge and safety. Candidates should prepare for questions related to plastering materials, lath and bases, gypsum plaster, Portland cement plaster, stucco systems, acoustical plaster, swimming pool interiors, surface preparation, repair methods, application procedures, curing, tools, equipment, and OSHA construction safety. Since the exam has only 30 questions, every topic can affect the final score.

Plastering materials questions may involve gypsum plaster, cement plaster, sand mixtures, stucco, accessories, and finish materials. Candidates should understand how different materials are selected, mixed, applied, and finished. Material performance can depend on the surface being coated, the conditions at the jobsite, the number of coats, the thickness of the application, and the curing process.

Lath, base, and substrate questions may involve metal lath, plaster bases, metal studs, metal grid systems, attachment, backing, support, surface condition, and preparation before plaster is applied. A plastering system depends on proper support and preparation. Poor base preparation can lead to cracking, delamination, uneven finish, or reduced durability.

Safety questions may involve OSHA construction standards, personal protective equipment, scaffolds, ladders, fall protection, tool safety, material handling, silica exposure awareness, respiratory protection awareness, housekeeping, and jobsite hazard recognition. Plastering work can involve elevated work, cutting materials, mixing, spraying, dust, wet materials, and repetitive handling, so safety is an important part of exam preparation.

Open Book Test

The Arizona R-36 Plastering exam is an open book test. Candidates are responsible for bringing their own approved references to the examination center. Approved reference materials may be highlighted, underlined, annotated, and indexed before the exam session begins. Candidates may not write, highlight, underline, or index inside the references during the examination session.

Reference books may be tabbed or indexed with permanent tabs only. Permanent tabs are tabs that would tear the page if removed. Temporary tabs, removable sticky notes, and other removable tabs are not allowed and must be removed before the exam begins. Candidates may not bring loose papers or attached papers with the approved references.

If a candidate uses a permitted reference downloaded from the internet, the material must be bound before being brought into the testing center. A bound reference may be spiral bound or hole-punched and placed in a binder when allowed by the exam instructions. Candidates may use a silent, nonprinting, non-programmable calculator in the examination center.

The approved references allowed in the exam room are Code of Federal Regulations – 29 CFR Part 1926 (OSHA), Gypsum Construction Handbook, 7th Edition, Plastering Skills, 1984, and Portland Cement Plaster (Stucco) Manual. Candidates should use these books during preparation, become familiar with their organization, and bring only compliant reference materials into the testing center.

Open book testing rewards students who study with the references before the exam. Simply bringing the books into the testing center is not enough. Candidates should know where OSHA safety rules are found, where gypsum plaster topics are located, where stucco application guidance appears, and how plastering methods connect to the approved references. This online exam prep course supports that process by helping students build stronger topic awareness and reference familiarity.

Licensing Steps

Arizona contractor licensing is handled by the Arizona Registrar of Contractors. A candidate pursuing the Arizona Plastering Residential Contractor (R-36) license should begin by confirming that the R-36 residential classification matches the type of plastering work the business intends to perform. The qualifying party must complete the examination requirements connected to the license classification.

Many Arizona contractor license applicants must complete the applicable trade exam and the Arizona Statutes and Rules Training Course and Exam. The trade exam measures plastering and construction knowledge for the license classification, while the statutes and rules requirement covers Arizona contractor law and regulatory responsibilities. Candidates should follow the Arizona Registrar of Contractors application process for the business structure, qualifying party, experience, bonding, and supporting documents that apply to the license being pursued.

A practical preparation path begins with identifying the correct classification, reviewing the exam subject areas, gathering the approved reference books, and setting a realistic study schedule. After preparation, the candidate schedules the trade exam through PSI and follows testing center rules for identification, reference materials, calculators, personal items, and exam-room conduct.

After the required examination steps are completed, the applicant continues through the Arizona Registrar of Contractors licensing process. This may include submitting the license application, identifying the qualifying party, providing required business information, meeting bonding requirements, and satisfying other state requirements connected to the applicant and classification.

State Requirements

The Arizona R-36 Plastering classification is a residential contractor classification. It allows the licensee to install laths, metal studs, metal grid systems, or other bases as required for the licensee to coat surfaces by trowel or spray with combinations of sand mixtures such as stucco, gypsum plaster, cement, acoustical plaster, and swimming pool interiors, excluding tile.

This classification is focused on residential plastering work and related plaster base preparation. Candidates should understand the practical tasks connected to the classification, including surface preparation, lath installation, base installation, plaster mixing, trowel application, spray application, finish coat application, repair work, curing awareness, and jobsite safety.

Arizona issues separate contractor license classifications for commercial work, residential work, and dual residential/commercial work. The R-36 classification is the residential plastering contractor classification. Applicants should make sure the classification fits the type of contracting work they plan to offer before moving forward with exam preparation and licensing paperwork.

Plastering work can affect appearance, durability, weather resistance, surface performance, and customer satisfaction. Poor preparation, weak attachment, incorrect mix handling, improper curing, uneven application, or unsafe work practices can create serious problems. Exam preparation should reflect this responsibility by reviewing plastering materials, gypsum systems, stucco methods, plastering tools, application techniques, repair practices, and OSHA safety.

Test Information and Study Materials

The Arizona R-36 Plastering exam is short, focused, and timed. With 30 questions in 75 minutes, candidates should prepare to work efficiently. A strong study routine includes reviewing plastering topics, reading key reference sections, learning the structure of each book, marking important pages before exam day, building approved permanent tabs, and practicing with questions that reinforce trade understanding.

Surface preparation should be one of the first areas students review. Plaster and stucco systems rely on proper preparation before material is applied. Candidates should study cleaning, backing, substrate condition, base installation, lath attachment, moisture awareness, and preparation requirements for different surfaces. Poor preparation can reduce bond, create cracks, cause uneven finish, or lead to premature failure.

Lath, metal studs, metal grid systems, and plaster bases are important because they provide support for the finished plaster system. Candidates should review how bases are installed, how lath is supported, how accessories are used, and how framing or grid systems affect the finished work. The relationship between the base and plaster material is central to long-term performance.

Gypsum plaster preparation should include gypsum materials, base coat and finish coat awareness, veneer plaster concepts, wall and ceiling applications, finishing quality, surface treatment, and repair practices. Gypsum plaster requires attention to timing, mixing, substrate condition, and finish technique. Students should become familiar with how gypsum systems are described in the approved reference materials.

Portland cement plaster and stucco preparation should include cement plaster materials, sand mixtures, scratch coats, brown coats, finish coats, lath, accessories, control joint awareness, curing, weather conditions, and exterior application practices. Stucco is a common plastering subject because it involves both material knowledge and field technique. Candidates should understand how application methods and curing affect durability and appearance.

Acoustical plaster preparation should include material awareness, surface texture, application conditions, finish quality, and how acoustical plaster differs from standard gypsum or cement plaster systems. Even when a topic is not the largest part of the exam, students should study the basic material and application concepts so they are prepared for focused questions.

Swimming pool interior preparation should include plaster materials, surface preparation, application awareness, finish quality, curing, and the distinction between plaster interiors and tile work. The R-36 classification includes swimming pool interiors, excluding tile, so candidates should understand this part of the scope and study the plastering methods that apply.

Tools and equipment preparation should include trowels, hawks, floats, mixers, sprayers, scaffolds, ladders, cutting tools, measuring tools, and cleanup equipment. Candidates should understand which tools are used for specific plastering tasks and how tool selection affects productivity, finish quality, and safety.

OSHA Safety should be studied throughout the preparation process. Candidates should review scaffold safety, ladder safety, fall protection, personal protective equipment, respiratory hazard awareness, silica exposure awareness, tool safety, material handling, housekeeping, and hazard recognition. Plastering work can involve overhead application, elevated work platforms, dust, wet materials, heavy bags, mixing equipment, and spray equipment, so safety knowledge is essential for both the exam and field performance.
