They are also harder to do well than walls. Working overhead is tiring and slow, light hits a ceiling at a low angle that reveals every lap mark, and stains or old texture need their own treatment. This guide explains what is involved so you can plan the job and know what to expect.
Why ceilings need their own approach
Light from windows skims across a ceiling, so small differences in thickness show up as streaks or lap marks. Painters work in sections, keep a wet edge and roll in a consistent direction to avoid them. A flat finish is the usual choice because it hides these variations and does not reflect glare from light fixtures.
Order matters too. Ceilings are normally painted before the walls, so any drips or splatter land on surfaces that will be painted next, and the line where ceiling meets wall is cut in cleanly once the walls are done.
Choosing a ceiling colour
Most ceilings are painted a flat white made for ceilings, which reflects light well and hides imperfections. A plain white is not the only option, though. A ceiling tinted slightly with the wall colour can make a room feel more cohesive, and a darker ceiling can make a large room feel cosier.
Keep in mind that a white ceiling can look grey or warm depending on the walls around it and the light in the room. Testing a sample on the ceiling itself, not on a board held at eye level, gives the truest result. Our guide to choosing paint colours explains how light and undertones change what you see.
Water stains, smoke and discolouration
Yellow or brown rings on a ceiling usually come from water. The first step is always to find and fix the leak, whether it is a bathroom above, a roof or a plumbing line. Painting over a stain while the leak continues only hides the problem for a short time.
Once the area is dry, water marks and smoke or nicotine staining need a stain-blocking primer before the finish coat. Ordinary ceiling paint on its own often lets these stains bleed back through. Damaged or sagging drywall around a leak is a repair rather than painting, and is assessed separately.
How a ceiling is usually painted
The room is prepared first: furniture is grouped and covered, floors are protected, and light fixtures and smoke detectors are masked or loosened so paint does not get on them. Cracks along drywall joints and nail pops are filled and sanded so they do not show through the new coat.
The edge where ceiling meets wall is cut in with a brush, then the main surface is rolled in overlapping sections while the edge is still wet. Working in one direction and keeping a consistent amount of paint on the roller is what prevents streaks. Most ceilings need two coats for even coverage, especially when going from a stained or yellowed ceiling to a bright white.
High ceilings, stairwells and cathedral ceilings need extension poles, ladders or scaffolding, which is one reason they take longer and are priced differently from a standard room. Lighting conditions matter here too: painters check their work from several angles, because a lap mark invisible from one spot can be obvious from another.
Textured and popcorn ceilings
Textured ceilings can be painted, but the texture absorbs paint and can loosen if it is soaked or rolled too heavily, so it is usually sprayed or rolled carefully with the right nap. Some people choose to remove the texture instead for a smooth, modern look.
Some older textured ceilings contain asbestos. If your ceiling texture is original to an older home, have it tested before anyone sands, scrapes or removes it. Painting over intact texture does not disturb it the way removal does, but the decision should be made with the test result in hand.
Smooth ceilings that were patched in the past can also show the repair through a fresh coat, especially under a low-angle light. Skim-coating and sanding a patched area before painting gives a more even surface, and is something to discuss when the ceiling is assessed.
Questions about ceiling painting
Should the ceiling be the same white as the trim?
Not necessarily. Trim is often painted in a harder, shinier finish, while ceilings usually use a flat finish. Many homes use the same white in different sheens; others choose a softer white for the ceiling so it looks less stark.
Why does my ceiling look patchy after painting?
Patchiness usually comes from uneven coverage, paint drying at the edges before the next section is rolled, or light catching a slightly glossier area. A second coat applied evenly in one direction normally solves it.
Should ceilings be painted before walls?
Yes, in most cases. Painting the ceiling first means drips land on walls that are about to be painted, and the ceiling line can be cut in cleanly afterwards.
How long does a ceiling take to paint?
It depends on the size, height, condition and number of coats. A standard ceiling in good condition is far quicker than a high, stained or textured one, which is why ceilings are assessed room by room.
Can I just paint over a water stain?
Not reliably. Fix the leak, let the area dry, then use a stain-blocking primer before the ceiling paint, otherwise the stain tends to show through again.
Does GOPAINT paint ceilings?
Yes. We paint walls, ceilings, trim and doors, and floors and furniture are protected during interior work.
