CSLB C-33 Painting & DecoratingPlanning and EstimatingMedium
A painting contractor is preparing a bid for a commercial project. The specifications require compliance with 'SSPC-SP 10 Near-White Blast Cleaning.' What does this specification primarily dictate for the contractor's planning?
- AThe specific type of paint to be applied after surface preparation.
- BThe required dry film thickness of the coating system.
- CThe environmental conditions suitable for paint application.
- DThe method and degree of surface preparation for steel substrates.
Show answer & explanationAnswer & explanation
Correct answer: D. The method and degree of surface preparation for steel substrates.
SSPC (Society for Protective Coatings) standards, particularly SP (Surface Preparation) standards like SP 10, define the acceptable methods and degree of cleanliness for preparing steel and other surfaces before coating application.
Why the other options are wrong
- A. Paint type is covered by separate material specifications, not SSPC-SP 10.
- B. Dry film thickness (DFT) is a coating application specification, not surface preparation.
- C. Environmental conditions are covered by other standards or general project specs, not SSPC-SP 10.
SSPC Standards
SSPC (Society for Protective Coatings) standards provide industry guidelines for surface preparation, coating application, and inspection, primarily for steel structures.
- SP (Surface Preparation) standards define cleanliness and profile for surfaces.
- PA (Paint Application) standards cover coating application procedures.
- They are crucial for ensuring coating longevity and performance.
Memory trick: SSPC-SP cleans the canvas before the paint brush can start.
