Drywall Board Inspection and Common Issues

Four Key Problems to Check:

1. Cupping on Beveled Edges

• Problem: Cupping occurs on backside of beveled edges

• Remedy: Bridge with drywall adhesive to fill gaps and prevent movement using screw taping

2. Burned Beveled Edges

• Problem: Soft edges burned more than 1/8 inch, causing raised lines in seam centers

• Remedy: Requires costly trimming of seams and removal of unset gypsum material with prefilling

3. Fractured Butt Ends

• Problem: Sheet ends can be fractured

• Remedy: Chamfer the butt ends and pre-fill gaps to prevent movement

4. Raised Shoulders

• Problem: Common washing up from beveled edges

• Remedy: Hand trowel scenes to taper, making seams wider

Pre-Filling Guidelines
