CSLB C-33 Painting & DecoratingPlanning and EstimatingMedium
A painting contractor is preparing a bid for a new construction project. The specifications indicate that all interior walls require a 'Level 4 finish' for painting. How does this specification primarily impact the contractor's estimation for painting?
- AIt requires additional preparatory work for the substrate, such as skim coating and sanding, before painting.
- BIt means fewer coats of paint will be needed, reducing material and labor costs.
- CIt implies that only roller application is permitted, prohibiting spray techniques.
- DIt mandates the use of specialized, high-VOC paints to achieve a smoother finish.
Show answer & explanationAnswer & explanation
Correct answer: A. It requires additional preparatory work for the substrate, such as skim coating and sanding, before painting.
A Level 4 finish requires the substrate to be very smooth, often achieved through skim coating and extensive sanding of drywall, which directly increases the labor and material costs associated with surface preparation before paint application.
Why the other options are wrong
- B. The number of paint coats is determined by coverage rates and desired opacity, not directly by the substrate finish level, though a smoother surface might sometimes require less paint to achieve uniformity.
- C. The finish level dictates surface preparation, not the method of paint application (roller vs. spray).
- D. Level 4 finish refers to surface smoothness, not paint chemistry or VOC content.
Level 4 Drywall Finish
A drywall finish level that includes taping, finishing joints, and applying a coat of joint compound over all surfaces, often requiring skim coating.
- Requires extensive surface preparation for a smooth finish.
- Suitable for flat paints or light textures.
- Increases labor and material costs for preparation.
Memory trick: Smooth walls mean more work, like a detailed Level 4 dance.
