Average cost for drywall installation — Portland, OR

Drywall installation near you in Portland involves several steps. First, the specialists will measure and cut drywall panels to fit the walls and ceilings. They then hang these panels, securing them to the wall studs and ceiling joists with screws. After the panels are in place, they apply joint compound to the seams and screw heads, embedding drywall tape.

Mudding drywall refers to the process of applying joint compound, often called 'mud,' to the seams between drywall panels and over screw or nail heads. It involves applying the mud in thin layers, embedding drywall tape into the first layer, and then feathering the edges of each coat to blend it with the surrounding drywall. Multiple coats are typically needed, with sanding between each application.

Drywall tape bubbles usually occur when not enough joint compound is applied beneath the tape, or when air pockets get trapped during application. As the compound dries, these air pockets create raised areas. The fix involves carefully slitting the bubble with a utility knife, ensuring the tape is flat against the wall. Then, apply a thin layer of joint compound over the area, feathering the edges. After it dries, sand smooth. Multiple thin coats are often needed to fully conceal the repair.

The most common types of tape used for drywall are paper tape and fiberglass mesh tape. Paper tape is embedded in joint compound and provides a strong bond for seams. Fiberglass mesh tape is self-adhesive, making it easier to apply, and is often used for patches or in areas where a very smooth finish is critical.

Greenboard drywall is a good choice for moisture-prone areas in Portland's climate, such as bathrooms and kitchens. Its moisture-resistant properties help prevent mold and mildew, which can be an issue with the region's humidity. While it's not designed for direct water exposure, it offers better protection than standard drywall in damp environments. It's a practical option for areas where humidity levels are consistently higher.

PVA drywall primer is a water-based primer commonly used on new drywall surfaces. PVA stands for Polyvinyl Acetate. It seals the porous paper facing of the drywall and the joint compound, ensuring an even absorption of paint. This prevents 'flashing,' where the difference in sheen between the paper and the mudded joints becomes visible after painting. Using PVA primer creates a uniform surface for your paint, leading to a much better final finish.
