Drywall tape bubbles — Henderson, NV

Essential drywall finishing tools include taping knives of various sizes, a mud pan, a hawk, and sanding tools like sponges or pole sanders. A utility knife is also necessary for cutting. For larger jobs, a drywall screw gun can be helpful. The right tools ensure a smooth, professional finish.

Drywall compound, or 'mud,' is a plaster-like material used to cover drywall tape and fasteners. Typically, three thin coats are applied over seams and screws. Each coat is allowed to dry and is sanded smooth before the next is applied.

Patching a hole in drywall involves cleaning the edges of the damage. For small holes, spackle is applied directly. For larger holes, a piece of drywall is cut to fit, then taped and mudded over. The process requires several layers of compound and sanding to blend it in.

Common drywall thicknesses include 1/4-inch, 3/8-inch, 1/2-inch, and 5/8-inch. Half-inch is standard for walls and ceilings in most residential applications. Thicker panels like 5/8-inch offer better soundproofing and fire resistance. The thickness chosen depends on the specific structural requirements.

PVA drywall primer is ideal for new, unpainted drywall surfaces. It seals the porous paper and joint compound, ensuring even paint absorption. This prevents uneven sheen and color variations. It's applied after the mudding and sanding are complete but before the final paint coats.

Drywall corners are the edges where two walls meet or where a wall meets a ceiling. Outside corners are reinforced with metal or vinyl corner bead, which is then covered with compound. Inside corners are typically taped and covered with compound to create a smooth, durable transition.
