100+ Free AMPP CCAS Practice Questions

The AMPP Concrete Coating Applicator Specialist (CCAS) is an applicator-focused credential awarded through a 4-day in-person course that ends with a 50-question written exam and a hands-on practical specialty exam. It is delivered by AMPP (Association for Materials Protection and Performance, formed by the 2021 NACE + SSPC merger). The CCAS validates that an applicator can properly prepare concrete substrates per SSPC-SP 13 / NACE No. 6 and ICRI 310.2R, conduct moisture tests per ASTM D4263 / F1869 / F2170, mix and apply 100% solids epoxy, polyaspartic, polyurea, MMA, and urethane cement systems, manage pot life, and follow OSHA respiratory and silica safety rules.

The CCAS exam has two parts. The written final exam consists of 50 multiple-choice questions and requires a score of at least 70% to pass. The practical specialty exam is a hands-on evaluation of the candidate's ability to prepare concrete, mix coatings, and apply the system under instructor observation during the 4-day course. Both portions must be passed to earn the credential. The course also awards 3 Continuing Education Units (CEUs).

There are no formal prerequisites listed for the CCAS course itself — anyone may register. However, AMPP strongly recommends field experience with concrete coating application before attempting the certification because the course is intensive and the practical exam evaluates real applicator skills (mixing, squeegee technique, broadcast, and trowel work). Candidates often come from industrial flooring contractors, secondary containment installers, and food / pharmaceutical facility maintenance teams.

Key standards include SSPC-SP 13 / NACE No. 6 (Surface Preparation of Concrete), ICRI Guideline 310.2R (Selecting and Specifying Concrete Surface Preparation with CSP 1 through CSP 9 profiles), ASTM D4258 (Standard Practice for Surface Cleaning Concrete for Coating), ASTM D4259 (Abrading Concrete), ASTM D4263 (Plastic Sheet Method for moisture), ASTM F1869 (Calcium Chloride MVER), and ASTM F2170 (In-situ Relative Humidity in Concrete Slabs). Safety standards include OSHA 29 CFR 1910.134 (Respiratory Protection), 29 CFR 1910.1053 (Respirable Crystalline Silica), and 29 CFR 1910.146 (Confined Spaces).

Pot life is the time after mixing the components of a two-component coating during which the material remains usable in the container — usually defined by a viscosity rise, exotherm, or doubling of initial viscosity. Working time (also called open time) is the practical time the material remains workable once spread out on the substrate, which is often longer than pot life because the thin film loses heat and reacts more slowly than the bulk in the pail. Recoat window is the time interval between coats during which the next coat can be applied with proper intercoat adhesion — too short risks solvent entrapment, too long risks loss of chemical bond and may require mechanical abrasion before recoating.

AMPP applicator credentials typically follow a 3-year renewal cycle, and AMPP allows credentials to be renewed up to 6 months before expiration through the My Certification Portal. Renewal requires meeting AMPP's continuing education and / or work experience documentation and paying the renewal fee. Allowing the certification to expire may incur reinstatement fees or suspension of the credential. Always confirm the current renewal policy on ampp.org or in your My Certification Portal.
