What is a C-35 Lathing and Plastering Contractor?
"A lathing and plastering contractor coats surfaces with a mixture of sand, gypsum plaster, quick-lime or hydrated lime and water, or sand and cement and water, or a combination of such other materials that create a permanent surface coating, including coatings for the purpose of soundproofing and fireproofing. These coatings are applied with a plasterer's trowel or sprayed over any surface which offers a mechanical means for the support of such coating and will adhere by suction. This contractor also installs lath (including metal studs) or any other material prepared or manufactured to provide a base or bond for such coating"-CSLB.GOV
Duties of a Plastering Contractor

To get the C-35 license, you have to be familiar with all aspects of this highly specialized trade.
The Contractors State License Board (CSLB) is the governing body for all contractors in the state of California.
Their sole responsibility is to protect the consumer public and ensure that anyone charging over $500 for construction services is qualified and registered with the state of California.
The C-35 License is issued to plastering contractors by the CSLB.
The CSLB administers applications, exams, and maintains a database of all active and inactive contractor license numbers which are public domain.

How to become a Plastering Contractor
To get a C-35 license in California, you must meet the following requirements:
You must also have:
What is a Journeyman level experience?
Journeyman level experience means that you have worked unsupervised full time for a plastering company, or for a contractor that holds the C-35 License.
- A journeyman can perform all of the duties associated with his or her trade.
The CSLB will want to see four full-time years over the last ten years. The years do not need to be consecutive, but they do need to be four years in total.
Signature of a Qualifying Individual
The following people may be used as Qualifying Individuals to sign off on your experience when applying for the C-35 license:
Work Experience for the C-35 License
You must be prepared to submit documentation supporting the experience you claim to have. The Contractors State License Board gives you a few ways that you can prove your experience.
- Tax Returns
- Check Stubs
- Material Order Invoices or Receipts
The CSLB receives thousands of applications per month so there is a good chance they won’t document your experience but if you are one of the applicants that get reviewed you will need to be ready to submit something.
The CSLB does not accept pictures of projects.
Filling out the C-35 License Application
Your Qualifying Individual will also need to provide a brief but detailed description of your masonry knowledge and skillset.
The way this description is written will be critical to whether or not your application is accepted. For example:
Writing: “Jim has created plaster walls” will not be descriptive enough for the CSLB
They will be looking for something more like:
"Jim has done plaster/stucco installations and repairs, gypsum float coat finish, framed around door openings, maintained and repaired equipment, and done pre-lath inspections" etc.
Application Processing, Fees and Criminal History
The time it takes to get your application processed and assigned a test date fluctuates throughout the year.
Typically you can expect:
- 6-8 Week Application Processing Time
- 3-4 Week wait for an Exam date
I have seen some situations where applicants got their test date sooner and some where they got their test date much later.
The most common reasons your application would get held up are:
- Time of year (processing time slows down during the holidays)
- Criminal History
- Proving Experience
- Mistakes on your application
Application Costs for the C-35 License
The Current CSLB fees are:
Can you get a Contractors License with a Felony in California?
Having a criminal record in no way stops you from getting a C-35 License. Thousands of contractors get licensed each year in California despite having a criminal record.
The key is to be honest on the application, even if the felony or misdemeanor happened years ago and even if it was expunged.
BE 100% HONEST ON THE APPLICATION, because they will see everything anyway when you do fingerprinting. The CSLB handles criminal records on a case by case basis.
Remember, their responsibility is to protect the public. In my experience, they primarily concerned with criminal charges associated with: Fraud, Embezzlement and Forgery.

Contractor license exam prep
Some things to remember:
- The questions you will see on the exam may use outdated terms
- Processes may be completely different from how things are done on the job site
- You will see questions about things you may have never done before
- Questions will be presented to you as if you are running a large scale construction business with several employees and jobs happening all at once.
- Know all aspects of your trade
I have helped all types of tradesman from various backgrounds and experience levels get licenses. Most are startled by how different the subject matter on the state exam is from their years of first-hand experience.
Be as prepared as you possibly can. Studying just 10 mintues a day consistently can dramatically increase your chances of passing the test on your first try.
Focus on and study ONLY the information that you need to pass the C-35 License exam.
Construction is a trillion-dollar industry and highly skilled plastering contractors are always in demand.
Whether you are completely new or have some experience already, there are resources available to you.
Generally someone looking to become a plastering contractor would want to look into an apprenticeship or find a skilled tradesman to learn under.

Blueprint Reading Course
Knowing how to read blueprints is a valuable skill virtually all tradesman but especially for those looking to get the C-35 License.
Construction blueprints provide a visually representation of a project, which can be valuable for tradesman making aesthetic alterations to the interiors.
Blueprint Reading Skills are also critical to pass the General Contractor exam. Check out this Blue Print Reading Course for a basic introduction to the concepts you will want to know about.
