Drywall Finish Levels: The Six Numbers That Turn “Finished” Into Something You Can Hold a Taper To

In February a homeowner on a forum posted photos of raised seams and visible tape, and the contractor’s answer was that she had bought Level 4, not Level 5. He was wrong about that too, as it happens, because what was in the photos was not Level 4 either. But the point stands: the levels exist, they are published, and if the number is not in your contract you are arguing about adjectives. The Gypsum Association’s GA-214 document defines Levels 0 through 5. Here is what each one is, in plain words, and where it goes in a house.

GA-214, Recommended Levels of Finish for Gypsum Board, is the industry standard in Canada and the US. The summary below is mine; the document is linked at the bottom.

The levels

LevelWhat is doneWhere it belongsOntario cost, per sq ft
Level 0Board hung, nothing else. No tape, no compound.Temporary construction, or a wall whose finish has not been decided.$0 over hanging
Level 1Tape embedded in compound at all joints and inside corners. Excess compound left as is. Fastener heads and bead not required to be coated. Often called fire taping.Above ceilings, in attics and plenums, in garages where only a fire separation is required and appearance is not.$0.50
Level 2Level 1 plus one coat of compound over the tape, the fastener heads and the bead. Tool marks and ridges acceptable.Garages, workshops, storage, and as the backer behind tile and heavy wall coverings.$0.75
Level 3Level 2 plus a second coat over joints, corners, fasteners and bead. Smooth, no tool marks or ridges. Sealed with primer before decorating.Walls getting heavy texture (knockdown, orange peel) or heavy-grade wall covering. Not for paint.$1.00
Level 4Level 3 plus a third coat over everything, sanded, smooth, primed before decorating. The standard “paint-ready” wall.Walls and ceilings getting flat or light-texture paint, or light wall coverings. Most of most houses.$1.50
Level 5Level 4 plus a thin skim coat of compound (or a manufacturer’s high-build primer-surfacer applied to spec) over the entire surface, so paper and compound are uniform. Then primed.Ceilings, walls under critical lighting (big windows, pot lights, wall washers), and any gloss, semi-gloss, satin or dark paint.$2.50

Costs are Southern Ontario, October 2026, board already hung, before HST. They are the rates in the taping calculator.

What the standard says that quotes leave out

Three things in GA-214 matter for your contract. First, every level from 3 up says the surface should be primed before any decoration, and the standard names the primer as part of achieving the look; a wall with no primer is not a finished Level 4 wall whatever the taper did. Second, the standard says the level should be chosen with the final decoration and the lighting in mind, which is the technical way of saying that Level 4 under a semi-gloss or beside a floor-to-ceiling window is the wrong level and the taper will tell you so afterwards. Third, Level 5 is a skim coat or an equivalent surfacer, over everything, not a fourth coat on the joints. Some tapers sell “Level 5” that is Level 4 with wider feathering. Ask what goes between the joints.

The sentence for your contract: “Walls finished to Level 4 and ceilings to Level 5 as defined in Gypsum Association GA-214, inspected under a raking light before primer; defects found at primer to be corrected by the finisher.” That one line settles most drywall disputes before they start. The rest of the contract.

Which level where, in a real house

  1. Garage: Level 2, or Level 1 if it is only a fire separation and nobody will ever paint it. Type X where the separation calls for it.
  2. Mechanical room, storage, under the stairs: Level 2 or 3. Nobody is lighting it from the side.
  3. Behind tile, behind a backsplash: Level 2 at most. Compound under tile is a weak layer. The tile setter wants bare taped board.
  4. Bedrooms, closets, hall walls with flat or eggshell: Level 4. Properly done and properly primed, it is a fine wall.
  5. Every ceiling you will look at: Level 5. The ceiling is lit from the side by everything in the room. Ceilings.
  6. The great room wall with the big window, the dining room in navy, the hall in semi-gloss: Level 5. The full case for each.

Questions people ask

What is the difference between Level 4 and Level 5 drywall?

Level 4 is three coats on the joints and fasteners, sanded. Level 5 is Level 4 with a skim coat over the whole surface so the paper and the compound take paint identically. Level 5 is for critical light and sheen paint; Level 4 is for everything else. About $1 a square foot between them.

What drywall finish level is standard for a new house?

Level 4 on walls and ceilings in a production house. In a custom house, Level 4 walls and Level 5 ceilings is the sensible middle, with Level 5 on walls that get a dark colour, a sheen or a window beside them.

How many coats of mud for Level 4?

Three over the joints and corners, three over fastener heads and bead, each dry before the next. Two coats is Level 3, and Level 3 is not a paint finish.

Is Level 5 a skim coat or a primer?

Either, under the standard: a skim coat of compound over the entire surface, or a high-build primer-surfacer applied as the manufacturer specifies. The skim coat is more common and more reliable; the surfacer is a painter’s product and belongs in the painter’s scope if that is the route.
