A nail in drywall cannot hold very much—usually only a few pounds. A nail in a stud can add support and hold around 20 pounds. If you are trying to hang something heavier, get some help from drywall anchors—toggle bolts are very strong and able to withstand more weight.

Drywall mud should be left to dry for at least 24 hours before sanding, though drying time depends on the thickness of the application, humidity, and room temperature. Thicker layers or projects done in high humidity may require 48 hours or more of drying time. You’ll know the mud is ready when it feels completely dry and appears light in color throughout. Sanding too early can cause smudging or gouges, so patience is key for a smooth, professional-looking finish.

You can take a few steps to save money on drywall installation, even when hiring a professional to do the bulk of the work for you. These ideas include the following:

• Buy the drywall and other materials yourself to avoid product markup and delivery fees

• Ask about discounts if you use the same company to tape, spackle, and paint

• Hire drywall professionals in the winter when demand is the lowest

• DIY as many parts of the project as possible, like replacing insulation and painting

While every home has its own unique needs, ceiling drywall installation typically follows a staggered or stepped pattern to enhance structural integrity and reduce the visibility of seams. Starting from one corner, sheets are placed perpendicular to the ceiling joists, with the ends of adjacent sheets meeting along the center of the joist. The next row begins with a half sheet, ensuring joints don't align vertically. This alternating pattern, combined with proper taping and mudding, creates a seamless appearance and strengthens the ceiling structure, minimizing the risk of cracks over time.
