Problem: Visible joints, ridging and tape delamination of drywall.

Cause: Improper application of joint tape and compounds.

Solutions:

• Make sure that the joint tape is completely embedded in the compound to prevent bubbling.
• Avoid using too much water in the mix or using heavy fills.
• Follow the manufacturer's directions and requirements.
• Allow joint compounds to dry completely between coats.
• Feather butt joints wider than edge joints as shown in Table 1 and Figure 66.

• Avoid over sanding the compound or sanding the paper that covers the surface of the drywall. This can result in "flashing" - different gloss text6ures on the joint and the drywall.
• In extremely bright areas, even minor surface flaws will be readily noticeable. Consider using a flat, or low-gloss (sheen) paint to minimize the visual effect of apparent defects.
