If you meet the above requirements you are half way there! 

I have helped thousands of painting contractors get the C-33 License in California, and the truth is that are 3 core skills you have to have to be successful and pass the contractor license exam your first try. 

1. Blueprint Reading

Blueprint reading is a core skill for anyone in a supervisory role on a construction site. Almost every construction trade will encounter blueprints of some kind. 

These skills are particularly important for contractors looking to get the painting license because 35% of the C-33 License exam is on planning and estimation.

A great resource for painting contractors looking to raise their game when it comes to reading blueprints and making accurate estimations is a website called: www.paintpro.net

Planning and Estimation (35%)

  • Evaluating job sites
  • Selecting tools, equipment, and materials
  • Selecting paint and stain colors
  • Reading blueprints and specifications
  • Calculating job costs

2. Environmental Safety

Painting Contractors have to be aware of the environmental impact of their work. Additives to paint products include

  1. Pigments (Titanium Dioxide and Zinc Oxide)
  2. Binders
  3. Solvents 
  4. Lead and Heavy Metals

Safety (22%)

  • Tool and equipment safety
  • Personnel safety
  • Environmental safety
  • Handling hazardous materials

Lead Paint specifically can cause nerve damage and brain disorders specially in children.

It is very important to understand the negative effects of lead paint and also how to contain it in a construction setting. 

The Environmental Protection Agency works closely with the Contractors State License Board to ensure that anyone applying for the painting license has a thorough knowledge of environmental safety

Getting an EPA Certification

Painting Contractors can get an EPA certification for lead safety in a 1 day (8 Hour) course. 22% of the Painting License exam contains questions on environmental safety and hazardous materials, so having this certification can help you greatly in your preparation!

3. Know Your Trade!

This goes without saying.

The Painting License is generally not considered the most difficult contractor license exam compared to others, but for someone who does not know the basics of their trade it can be incredibly difficult. 

The exam is:

It is important to remember that the vocabulary or topics on CSLB exam will probably differ greatly to the way things are done in the real world. You might encounter:

  • Out of date topics
  • Verbiage that no one uses anymore for tools
  • Processes that are never used in the real world

When studying for your painting license test, just remember that you are studying to pass the exam and nothing more. Your goal is to get the painting license and move on, not revolutionize the CSLB curriculum.

  • Use Online c-33 license exam questions
  • Study using a c-33 license Trade Book
  • Consider reviewing trade information with an online course or DVD class
  • Study consistently (even 10 minutes a day on a consistent basis is better than cramming)
