Drywall stilts — Cambridge, MA

Finishing drywall corners involves reinforcing the inside and outside angles to create a smooth, durable surface. For inside corners, drywall tape is embedded in joint compound and then smoothed on both sides. For outside corners, drywall corner bead is installed and then covered with joint compound, which is feathered out onto the adjacent walls. Multiple thin coats of compound are applied and sanded to achieve a clean, sharp line that blends seamlessly with the rest of the wall surface, ready for painting.

While drywall is typically fastened with screws, nails can sometimes be used, especially in older construction or for specific repair situations. If nails are used, they should be drywall nails, which have a ring shank for better holding power and a thin head that can be countersunk without tearing the paper. Professionals in Cambridge primarily use drywall screws, which provide a more secure and consistent hold, reducing the likelihood of nail pops. The screw heads are then covered with joint compound.

1/2 inch drywall is a standard thickness commonly used for walls in residential construction throughout Cambridge. It offers a good balance of strength, weight, and cost-effectiveness for most interior wall applications. While 5/8 inch drywall is often used for ceilings or areas requiring greater fire resistance or sound dampening, 1/2 inch is the go-to for general wall surfaces due to its ease of handling and installation, providing a solid base for finishing and painting.

Moisture-resistant drywall, often called 'greenboard' due to its colored paper facing, is designed to withstand higher humidity levels than standard drywall. It's commonly used in bathrooms, kitchens, and laundry areas, though it is not waterproof. For areas that will be directly exposed to water, such as shower stalls, waterproof panels or cement board are more appropriate. Professionals in Cambridge select moisture-resistant drywall to provide an added layer of protection against humidity and minor water splashes.

Sheetrock is a brand name for drywall manufactured by USG (United States Gypsum). While the term is often used interchangeably with 'drywall,' it specifically refers to the gypsum-based panels produced by this particular company. Professionals understand that regardless of the term used, the material is gypsum plaster pressed between two thick sheets of paper, forming durable panels for interior walls and ceilings. The quality and properties of Sheetrock are similar to other drywall products used in Cambridge.

Drywall tape bubbles, also known as blisters, typically occur when air becomes trapped between the drywall tape and the joint compound during application. This can happen if the joint compound isn't applied evenly, if the tape isn't pressed firmly into the mud, or if the compound starts to dry before the tape is fully embedded. Professionals take care to apply a consistent layer of mud and ensure the tape is fully adhered and smoothed out to prevent these imperfections.
