Yes, it matters which side of drywall you use. One side is smooth, and the other is rough. The smooth side should be facing outward, toward the room, while the rough side should be hidden and facing the studs and framing of the house. The smooth side will be easier to apply tape, joint compound, and, later, paint to.

Plaster can be a difficult DIY to master, especially if you plan to plaster an entire room, rather than patch a small area. Before you begin a plaster DIY project, you need to know which tools and type of plaster to use. It's also important to know how to prepare the surface and apply the plaster for a smooth finish. If that all sounds like a lot of work, you may prefer hiring a local plaster repair contractor to do the job.

Yes, applying a texture can hide minor imperfections and irregularities in drywall, but it will not cover significant damage like nail marks or screw holes. The best texture depends on the size of the flaws. For minor imperfections, popular choices like orange peel, sand, or popcorn texture are effective. For larger imperfections, you may need a more prominent style, such as a knockdown or trowel finish, to conceal them effectively.

Yes, it is possible to rewire a house without removing the drywall, but this doesn’t work in all homes. You can pull out old wires and insert new ones if you have access to the wiring system via the ceiling or through a crawl space. Some pros can also use a magnetic kit to fish the old wire out of the wall through a hole cavity and install the new wires. Just keep in mind that doing this is less stable than removing drywall, as you won’t be able to staple the wires into the framing.
