Course format

Level 1: Two days- 16 Hours – Lecture + Written Exam

Level 2: One day – 8 Hours – Hands On Spray Exam

The Level 1 classroom session consists of a 6-8 hour review of the fundamentals of plural component spray technology. The review will cover the fundamentals of the process of spraying two component coatings using airless plural component spray pumps (e.g., material ratio, material viscosity, mixing, ambient conditions for application and curing, product data sheets, material safety data sheets, spray technique), equipment operation, troubleshooting basics and lessons learned, coating materials appropriate for plural component spray, and quality control basics.

The Level 2 hands-on assessment requires each student to operate two different types of plural component pumps and explain their operations. Candidates must wear appropriate personal protective equipment (PPE) during the hands-on workshop and must be able to answer questions about troubleshooting in cases where things go wrong with the spray pump operation. In order to pass, you must score 90% or better on the Level 2 exam.

There will be a Level 1 written, multiple-choice exam (25 questions). If a candidate fails, he or she must retake the exam. A total of 70 points is required to pass the Level 1 written exam. Candidates wishing to achieve the Level 2 Certification and CEUs must attend all 24 hours of the program and pass the Level 1 written exam with a score of 70% and the hands-on Level 2 exam with a score of 90%.
