Textured and popcorn ceilings: coverage, product and technique

Why texture eats paint

A ceiling’s area is the floor area below it, but a textured ceiling has far more surface than that. Every bump of an orange-peel finish, every ridge of a knockdown and every nodule of a popcorn (acoustic) ceiling adds surface that the paint has to wet. On top of that, many textures are porous: popcorn in particular is soft and absorbent, and the first coat soaks in. The result is that a gallon of ceiling paint labelled for 400 sq ft covers far less overhead. The second coat goes further than the first, because the first has sealed the surface, but it still has the extra surface of the texture to cover, so the factor applies to both coats.

How much more

We apply a factor to the label coverage, by texture:

The factors are estimates; a very heavy, dry, unpainted popcorn ceiling can take more still on the first coat, and a popcorn ceiling that has been painted before takes less. The ceiling paint calculator applies them, and paint coverage explained covers texture and porosity in general.

Before you paint popcorn: asbestos

Popcorn and other spray-on textures applied in US homes before the 1980s may contain asbestos. The US Environmental Protection Agency advises having such material tested by an accredited laboratory before sanding, scraping or otherwise disturbing it. Painting over sound texture without disturbing it is a common way to leave it in place, but if the texture is loose, flaking or damaged, get it tested first. Homes built before 1978 may also have lead-based paint on any surface; see the disclaimer on this site and the EPA’s guidance for renovation in older homes.

Which paint

Use a flat ceiling paint. Flat finishes hide the unevenness of a ceiling, which is lit at a raking angle by every window and lamp, and they do not show roller marks. Two kinds of ceiling paint help on texture:

• High-hide ceiling paints are thick and opaque, and often cover a ceiling of the same white in one coat. On a colour change or a stained ceiling, plan two.
• Colour-changing ceiling paints go on tinted, often pink or blue, and dry white, so you can see where you have been on a white ceiling. They are useful on texture, where missed spots are hard to see.

Water stains on a ceiling bleed through any ceiling paint. Spot-prime them with a stain-blocking primer first; the primer calculator covers stains.

Rolling a textured ceiling

• Use a thick nap. A 3/4 in or thicker roller cover, or a cover sold for popcorn ceilings, carries enough paint into the hollows. A short nap skips over them and leaves white pinholes.
• Load fully, roll lightly. Let the roller do the work. Pressing hard or rolling back and forth on popcorn can soften it with water from the paint and pull it off the ceiling in patches.
• One direction for the first coat, across it for the second. Crossing the coats fills the texture from both sides.
• Do not overwork it. A popcorn ceiling that has never been painted absorbs water quickly; roll a section once and move on.
• Test a corner. If the texture lifts on the roller, stop and switch to spraying.

Spraying a textured ceiling

Spraying is the gentlest way to paint popcorn, because nothing touches the texture, and it fills every hollow evenly. It costs more paint, because of overspray, and it means masking the whole room: walls, floor, windows, light fittings.

On an empty room that is being repainted top to bottom, spraying the ceiling before the walls means the overspray on the walls is painted over anyway. The spraying versus rolling guide covers tip sizes and technique.

Ceilings that are not white

A coloured ceiling, whether a pale tint of the wall colour or a deep colour in a dining room, is painted the same way but planned like a wall. The ceiling paint calculator’s coats rule still applies: two coats for any change, and a tinted primer or a third coat for a big jump from white to a deep colour. Texture makes coloured ceilings harder, because every missed hollow shows as a white pinhole against the colour, so a thick nap and two crossed coats matter even more. A flat sheen is still the safe choice; a ceiling in eggshell or satin shows every roller lap in the light from the windows.

Checking your work

Missed spots on a white-on-white ceiling are almost invisible while you work and obvious the next morning. Three habits help:

• Work towards the light. Start at the window wall and roll away from it, so the wet paint reflects the daylight and you can see the edge of what you have done.
• Use a work light. A bright lamp on the floor, pointed along the ceiling, shows thin patches and holidays in the texture.
• Check from the doorway. Before the paint dries, look at the whole ceiling from where people will see it, and fix thin areas while you can still blend them.

Ceiling first

Whatever the method, paint the ceiling before the walls. Spatter and drips land on walls that are about to be painted, and the wall colour is then cut in against the finished ceiling. Painting a room walks through the order.

Removing texture instead

Some people choose to scrape popcorn off rather than paint it. It is messy, it needs the asbestos test first, and the ceiling underneath usually needs skimming before it looks smooth. Once a popcorn ceiling has been painted, it is much harder to scrape, because the paint seals it against the water that softens it. If removal is likely in the next few years, do it before painting, not after.

Common mistakes

• Planning with the 400 on the can. On popcorn, plan nearer 240.
• Using a short-nap roller. It skips the hollows.
• Pressing hard on popcorn. It comes down in sheets.
• Disturbing old texture without testing it. Test pre-1980s texture for asbestos first.
• Painting over water stains with ceiling paint. They come back; prime them.
• Painting walls first. Ceiling spatter lands on the finished walls.
