The wall surface is what every person in the room sees, touches, and judges. A poorly finished wall tells the whole story – visible seams, flashed joints, and uneven texture that no amount of paint can cover. RainFire Builders finishes walls and ceilings to the standard that paint, tile, and light demand, on every project, every time.
FROM BOARD TO BEAUTIFUL
What is Drywall & Plaster?
Drywall — also called gypsum board, wallboard, or by the trade name Sheetrock — is a manufactured panel product consisting of a gypsum mineral core pressed between two layers of paper facing. It is the dominant interior wall and ceiling material in North American construction because it installs quickly, finishes smoothly, and offers reliable fire-resistance and sound performance.
Finishing drywall is a separate and equally critical skill. Hanging the board is the beginning — then comes taping, applying multiple coats of joint compound, feathering each coat wider than the last, sanding between coats, and ultimately achieving a surface that is invisible under paint. The quality of a wall is decided by the finisher, not the painter.
Plaster systems — veneer plaster over blueboard, or traditional three-coat plaster over metal lath — produce harder, denser wall surfaces than standard drywall. They resist dents and dings, provide superior sound attenuation, and carry a refined, high-end aesthetic that remains the choice of discerning custom home clients across Utah’s luxury market.
Standard Gypsum Board
The workhorse of interior construction. 1/2″ is used for most wall applications; 5/8″ is standard for ceilings and where an added fire rating is needed. Available in 9′, 10′, and 12′ lengths for high-wall and cathedral applications.
Moisture-Resistant Board
Fiberglass-faced or moisture-resistant gypsum panels for bathrooms, laundry rooms, and any space subject to humidity. Cement board (HardieBacker, DuRock) is specified directly behind tile in wet areas.
Type X Fire-Rated Board
5/8″ Type X gypsum board is required in garage-to-living-space assemblies, shaft walls, stairwells, and commercial occupancies per Utah building and fire codes.
Blueboard / Veneer Plaster Substrate
A specially coated gypsum board designed to bond with finish plaster coats. The foundation of veneer plaster systems that produce a harder, denser, crack-resistant surface than standard taped drywall.

The RAINFIRE DRYWALL PROCESS
Great drywall finishing is a multi-day, multi-coat process. Skipping coats or rushing drying time — as less experienced crews do — produces walls that telegraph every imperfection under the first coat of paint. We don’t skip steps.
The right board for every location is specified before a single panel is ordered. Standard 1/2″ for interior walls, 5/8″ or 1/2″ lightweight for ceilings, moisture-resistant board in bathrooms and laundry, fire-rated Type X in required assemblies. Panels are hung with screws (not nails) to minimize fastener pops, and long edges run perpendicular to framing members. All butt joints are staggered and offset from corners.
Paper tape (not fiberglass mesh except in specific applications) is embedded in the first coat of joint compound over all seams, inside and outside corners, and any board-to-board transitions. Corner bead — metal or vinyl — is installed on all outside corners and secured flush. The goal at this stage is zero voids under the tape and a consistent, thin first coat. All fastener dimples receive their first fill coat.
After the tape coat is fully dry, a wider second coat is applied — feathered 4–6 inches beyond the first coat on each side of every seam. This coat begins to blend the joint into the flat surface of the board. A slightly lighter, more workable compound is used at this stage for better spread and reduced shrinkage. Utah’s dry climate means mud can dry faster, but our crews monitor conditions carefully to prevent surface cracking from drying too quickly.
The third finish coat is applied wider still — up to 10–12 inches across flat seams — with a large knife to achieve a seamless transition from the joint compound to the face paper of the board. This coat is applied as thin as possible to minimize shrinkage and avoid crowned joints. Butt joints (where the non-tapered ends of two panels meet) receive special attention at this stage — they are the most likely location for a visible seam under flat paint.
After all coats are completely dry, the entire surface is sanded — first with a pole sander, then by hand where needed — to eliminate ridges, tool marks, and any compound high spots. We sand under raking light, not flat overhead light, to catch any surface variation before paint is applied. A PVA drywall primer is applied to seal the paper face and joint compound before finish paint — an essential step that most production painters skip, and one that causes flashed (uneven sheen) walls.
