CSLB C-33 Painting & DecoratingPlanning and EstimatingHard
A painting contractor is reviewing the project specifications for a new commercial building. The specifications explicitly state that all interior walls must receive a Level 5 finish, followed by two coats of premium acrylic latex paint. Which of the following is the most significant implication of the Level 5 finish requirement for the contractor's bid?
- AReduced drying time between coats due to smoother surface.
- BElimination of the need for a primer coat.
- CSignificantly higher labor costs for surface preparation.
- DRequirement for specialized, high-gloss paint products only.
Show answer & explanationAnswer & explanation
Correct answer: C. Significantly higher labor costs for surface preparation.
A Level 5 finish is the highest standard of drywall finish, requiring skim coating the entire surface to achieve a uniform, smooth substrate, free of even minor imperfections. This intensive preparation significantly increases labor time and material use, making it the most impactful cost factor for the bid.
Why the other options are wrong
- A. A smoother surface does not inherently reduce drying time; drying time is a property of the paint and environmental conditions.
- B. A primer is still typically required for proper adhesion, sealing, and uniform appearance, even with a Level 5 finish.
- D. A Level 5 finish is suitable for all sheen levels, including flat and eggshell, and does not exclusively require high-gloss paints.
Level 5 Drywall Finish
The highest standard of gypsum board finish, requiring the entire surface to be skim-coated to provide a uniform surface suitable for critical lighting and high-sheen paints.
- Achieves the smoothest possible surface.
- Involves extensive skim coating and sanding.
- Significantly increases labor and material costs for drywall finishing and painting preparation.
Memory trick: Level 5 Labor: Smoothness Soars, So Does Spending.
