A property manager called me to a mid-rise lobby last winter, frustrated. She’d had it repainted twice in under a year, and under the pot lights you could still see every drywall seam and screw line telegraphing through the fresh coat. She was sure she’d hired a careless painter. She hadn’t — the paint was fine. The problem was the drywall finishing level underneath it. This post explains what drywall finishing levels actually are, why a Level 4 wall looks perfect in one room and patchy in the next, and where paying for a Level 5 finish is worth it. It’s written for property managers and condo boards, not homeowners.
1. “Finishing level” is a defined scale, not a painter’s opinion
There is an actual, published scale for how smooth a drywall surface is left before it’s painted. It runs from Level 0 — bare board, no tape — up to Level 5, the smoothest. Most people who hire painting have never heard of it, and that’s exactly why these arguments happen at a board meeting instead of before the work.
Level 4 is the common standard: the seams are taped, the joints and screw heads get three coats of compound, and everything is sanded flush. Level 5 goes one step further — a thin skim coat of compound over the entire wall, so the whole surface has one uniform texture and porosity, not smooth patches sitting in a slightly rougher field. It sounds like a small distinction. Under the wrong light it’s the difference between a wall that looks flawless and one that looks repaired.
What to look at: ask whoever quotes your drywall or your repaint what finishing level they’re pricing. If they don’t have an answer, you’ve already found your problem.
2. Level 4 looks perfect — until the light hits it sideways
A Level 4 wall is smooth where the compound is and very slightly different where it isn’t. In a room with soft, even light you will never notice. The trouble starts with what we call critical lighting: light that rakes across the wall at a low angle — floor-to-ceiling windows, wall-wash pot lights, a lobby sconce throwing light straight up a feature wall. That grazing light casts a tiny shadow off every seam and every screw dimple, and the whole grid of the drywall suddenly reads through the paint.
Sheen makes it worse. Flat paint hides a lot; anything with a shine to it — eggshell, satin, semi-gloss — bounces the light and amplifies every imperfection under it. So the “nicer,” glossier finish a board upgrades to is often the very thing that exposes the wall.
What to look at: walk your lobbies, corridors and amenity rooms at the time of day the light is lowest and hardest across the walls. If you can see the seams now, a fresh coat of paint will not remove them.
3. Level 5 is worth it in specific rooms — and overkill in others
I don’t tell every board to pay for Level 5 everywhere. That’s just spending the reserve fund for no reason. Level 5 earns its cost in exactly the places critical lighting lives: lobbies and entrances with a lot of glass, feature walls under directional lighting, amenity and party rooms, and anywhere you’re specifying a sheen above flat. A back-of-house corridor lit by a flat ceiling fixture does not need it.
The skim coat does one more thing: it gives the paint a single consistent surface to sit on, so the finish coat looks uniform and, in my experience, holds up better to the touch-ups these high-traffic rooms always end up needing. Getting the drywall genuinely paint-ready — the whole point of doing the surface prep right the first time — is what makes the paint above it last.
What to look at: make a short list of your building’s “seen” walls — the ones residents and visitors actually study under strong light. Those are your Level 5 candidates. Everything else is fine at Level 4.
4. The repaint trap — paint can’t fix what’s underneath it
Here is the part that quietly costs boards money. When seams start showing through, the instinct is to repaint, and often to repaint in a nicer, glossier colour — which, as we just covered, makes it worse, not better. A coat of paint is about three-thousandths of an inch thick. It cannot fill or hide a finishing-level problem. It can only lie on top of it, and if it has any sheen at all, spotlight it.
The real fix is to bring the wall up a level: skim-coat it to a Level 5, prime it, then paint. It’s more work than another repaint, but it’s done once. Repainting a Level 4 wall that needed a Level 5 is exactly how a building ends up, like that property manager, paying three separate times for the same wall.
What to look at: if a wall has already been repainted once and still shows its seams, stop repainting it. The next dollar belongs in the surface, not in another coat.
What to do if you’re seeing any of this
If your walls telegraph their seams under the light, or you’re about to repaint a lobby or amenity room and want it to actually look finished, the finishing level is the first thing to settle — before anyone opens a paint can. I assess drywall and paint condition across Ottawa and the surrounding areas — Kanata, Nepean, Barrhaven, Orléans, Stittsville, Manotick and Westboro — and I’ll tell you honestly which walls need a Level 5 and which are perfectly fine as they are. If you want to see how we get drywall genuinely paint-ready, or how we approach projects generally, there’s more on our work and services pages.
