A painting contractor is preparing to apply a finish coat to interior drywall surfaces. The specifications call for a Level 5 finish. Which of the following best describes the requirements for a Level 5 drywall finish?
- AJoints taped and fasteners covered with three coats of joint compound; surface ready for heavy texture.
- BJoints taped and fasteners covered with two coats of joint compound.
- CAll joints and fasteners covered, with a single coat of primer applied to conceal minor imperfections.
- DJoints taped and fasteners covered with three coats of joint compound, with a skim coat of joint compound applied to the entire surface.
Show answer & explanationAnswer & explanation
Correct answer: D. Joints taped and fasteners covered with three coats of joint compound, with a skim coat of joint compound applied to the entire surface.
A Level 5 drywall finish is the highest standard, requiring all joints and fastener heads to be covered with three coats of joint compound, followed by a thin skim coat of joint compound applied to the entire surface. This ensures a uniform surface that is free of imperfections, even under critical lighting conditions, and is suitable for high-sheen paints.
Why the other options are wrong
- A. This describes a Level 4 finish, which is common for flat paints but lacks the full skim coat for a truly uniform surface.
- B. This describes a Level 3 finish, which is not suitable for critical lighting or high-sheen paints.
- C. While priming is part of the painting process, a Level 5 finish specifically refers to the drywall preparation, which includes the skim coat before priming.
Level 5 Drywall Finish
The highest standard of gypsum board finish, achieved by applying a skim coat of joint compound to the entire surface after all joints and fasteners have been taped and coated.
- Provides a uniform surface, eliminating texture differences between board and compound.
- Required for critical lighting conditions (e.g., strong natural light, high-angle artificial light).
- Essential for high-sheen paints (semi-gloss, gloss) to prevent imperfections from showing.
Memory trick: Five levels for flawless walls, a skim coat covers all.
