Drywall Insulation questions, answered by experts

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

This depends on how much plaster is applied and in how many layers, but a decent estimate is around 150 square feet. If you are applying only two coats on a small wall, there is a chance you may only need one or two gallons for the entire project. If you are plastering a large living room wall with high ceilings, using one of the more involved techniques–like Scagliola–that requires several coats, expect the project materials costs to add up quickly. 

The easiest way to cut holes in drywall for electrical boxes is to use a spiral saw with a drywall router bit. Hang the drywall without cutting out a hole for the box, but make sure you measure and mark where the box is located on the wall. Once you screw in the drywall sheet, drill a small hole into the box void, insert the spiral saw bit, and move it around the edge of the box using the inside wall as a guide. You can also use an oscillating multi-tool with an electrical box cutout for fast, professional results.

On average, drywall installation costs around $2,000, with a typical range of $400 to $6,000, including materials and labor. The final price depends on several factors. The most significant is the size of the area, as many contractors charge per square foot. Other cost factors include the complexity of the job (e.g., cutting around multiple windows and doors, corners, or curved walls), accessibility, location, the thickness of the drywall, the height of the room, and the desired level of finish. The level of finish can range from simply hanging the drywall to taping and mudding the seams and painting the walls.

Damp plaster does dry out, although the drying time depends on several factors, including the type of plaster, the surrounding temperature, moisture content, and the extent of the dampness. Sometimes, it can take weeks or months for wall plaster to dry naturally.
