What to buy
14 sheets of 4 × 10 ft, 1.1 buckets of joint compound (69 lb), 224 linear ft of paper tape and about 644 screws.
480 ft² of surface — 368 ft² of wall130 — with 10% added for cuts and breakage.
Sheet length changes the job, not just the count
4 × 10 ft boards hung horizontally leave far fewer butt joints than 8 ft boards stood on end. Butt joints are the ones that show, because they have no tapered edge for the tape to sit in — every one has to be feathered wide enough to hide, and that is where the mud and the sanding hours go.
Longer boards are harder to carry and easier to finish. On a 8 ft wall the trade is usually worth it.
Level 4 is a specification, not a preference
Level 3 is two coats and belongs under heavy texture. Level 4 is three coats and is the normal standard for flat or eggshell paint. Level 5 skims the entire surface and costs about 40% more compound plus a great deal more sanding.
If the room has a big window down one side, raking light will show every joint that Level 4 leaves. That is when Level 5 earns its cost, and almost the only time.
Openings are only half deducted here
On purpose. You still cut board around a door and a window, and most of what comes out is offcut that fits nothing. Deducting the full opening area is exactly how people end up two sheets short with the van gone.
Two habits worth having
All-purpose compound for taping, lightweight for the finish coats — lightweight sands far more easily and sanding is where the hours are.
Set the driver clutch so the screw dimples the paper without breaking it. A screw that tears the face paper holds almost nothing, and you cannot see which ones did it once the mud is on.
Notes
- **Sheet length changes the job more than it changes the sheet count.** 4 × 10 ft boards hung horizontally on an 8 ft wall leave far fewer butt joints than 8 ft boards stood on end — and butt joints are the ones that show, because they have no tapered edge to bury the tape in. Fewer joints means less mud, less sanding and a flatter wall.
- **Level 4: three coats — the normal standard for flat or eggshell paint.** The finish level is a specification, not a preference — Level 4 under gloss paint or in raking window light will show every joint. Level 5 costs about 40% more mud and a lot more sanding, and it is the right answer for a wall with a big window down one side.
- Openings are only half deducted here, on purpose. You still have to cut the board around a door and a window, and most of what comes out is offcut. Deducting the full opening area is how people end up two sheets short.
- Buy the mud in buckets, not boxes, for anything this size — and buy all-purpose for taping and lightweight for the finish coats. Lightweight sands far more easily and that is where the hours go.
- Ceilings first, always, then walls — the wall boards hold up the ceiling edge. And ceilings take 15% more screws because the board is fighting gravity rather than resting on the plate.
- Screw spacing is 16″ on walls and 12″ on ceilings for a 16″ o.c. frame. Set the driver clutch so the head dimples the paper without breaking it — a screw that tears the face paper holds almost nothing.
