CSLB C-33 Painting & DecoratingPlanning and EstimatingEasy
A painting contractor is preparing a bid for a large commercial project. The project specifications indicate that all interior walls require a 'Level 4 finish' prior to painting. What specific characteristic of a Level 4 finish will most directly impact the contractor's labor and material estimates?
- AA Level 4 finish requires all fasteners, corner beads, and joint compounds to be feathered out and sanded.
- BA Level 4 finish requires the entire surface to be spackled and sanded smooth for uniform porosity.
- CA Level 4 finish requires all fasteners and corner beads to be concealed with joint compound.
- DA Level 4 finish requires two separate coats of joint compound applied over all flat joints and fasteners.
Show answer & explanationAnswer & explanation
Correct answer: A. A Level 4 finish requires all fasteners, corner beads, and joint compounds to be feathered out and sanded.
A Level 4 finish, as defined by industry standards, requires fasteners, corner beads, and joint compounds to be feathered out and sanded smooth. This directly affects labor for finishing and sanding, and material for joint compound, impacting the bid significantly.
Why the other options are wrong
- B. Spackling the entire surface for uniform porosity is not a standard requirement for a Level 4 finish; it's generally achieved through proper priming.
- C. This describes a Level 3 finish, which is less intensive than Level 4.
- D. While two coats are often applied, the critical factor for Level 4 is the feathering and sanding, not just the number of coats.
Level 4 Drywall Finish
A standard drywall finish where all fasteners, corner beads, and joint compounds are feathered out and sanded smooth, but not necessarily free of minor imperfections, providing a good surface for flat paints.
- Fasteners and corner beads are concealed.
- Joints are taped and treated with two separate coats of compound.
- All joint compound is feathered out and sanded smooth.
- Suitable for flat paints and light textures.
Memory trick: Each finish level builds on the last, getting smoother like a staircase to perfection.
