To paint a kitchen ceiling with grease on it, do three things in order: degrease it, seal it with a stain-blocking primer, then roll two coats of a stain-blocking ceiling paint in a flat or matte finish. Skip the primer and the yellow patch over the stove usually bleeds through the new paint. Skip the cleaning and the primer has a film of oil to grip instead of the ceiling.

This guide covers each step, the products and the mistakes that bring the stains back. It also covers when a job is better handed to a professional crew.

TL;DR

Wash the ceiling first with dish soap and warm water, or a degreaser used exactly as its label says, then wipe it with plain water and let it dry fully.
Prime the greasy areas with a stain-blocking primer made for grease. Ordinary primers are built for adhesion and do not necessarily block stains.
Use a stain-blocking ceiling paint in a flat or matte sheen, and plan on two coats.
Test a small patch for bleed-through before you paint the whole ceiling. Spot-prime again if the stain shows.
Before you scrub a textured ceiling in an older home, find out whether it contains asbestos.

Why grease ruins ordinary ceiling paint

Cooking releases fine oil droplets in steam. They rise and settle on the coolest, flattest surface above you, which is the ceiling. Over months the film collects dust and turns tacky and yellow, usually in a halo around the range hood, pot lights and pendants.

New paint over that film fails in two ways. First, it can’t bond properly to oil, so it may peel or look patchy. Second, the oil and discolouration migrate up through the fresh coat. A professional testing team reported that generic ceiling flat showed bleed-through after the first coat, and that the yellow halo around lights typically reappears within a few months when the ceiling is repainted without stain-blocking products.

That is why the order matters: remove what you can, seal what is left, then paint.

Three steps for painting over kitchen grease

Step 1: Check the ceiling before you touch it

Look at what you are dealing with before you reach for a sponge.

Smooth drywall or plaster: safe to wash with gentle pressure.
Textured or popcorn ceiling: it soaks up water and sheds particles. Better Homes & Gardens advises avoiding vinegar and scrubbing cautiously on these surfaces, and wearing a dust mask, goggles and gloves.
Older home: the same source suggests testing for asbestos before cleaning if the house was built before 1990. If you have an older textured ceiling, have it tested before you scrub, sand or scrape it.
Water stains as well as grease: brown rings with soft or bubbling drywall point to a leak. Fix the source first. Paint is not a repair.

If the ceiling is a popcorn finish and you would rather be rid of it than clean it, see our popcorn ceiling removal service.

Step 2: Degrease the ceiling

The goal is to lift the loose film so the primer reaches the surface. You are not trying to make the ceiling look perfect, because the primer does the rest.

What you need

A microfiber cloth or vacuum with a brush attachment
Warm water and dish soap, or a commercial degreaser
Soft cloths or a sponge, plus a soft-bristle toothbrush for stubborn spots
A bucket of clean water for rinsing
Gloves, eye protection and a stable stepladder
Drop sheets over the counters, stove and floor

A gentle method that works for most ceilings

Dust first. Run a dry microfiber cloth or vacuum over the ceiling so you are not turning dust into mud.
Mix the solution. Better Homes & Gardens recommends warm water with several drops of dish soap, wiped on in circular motions with a soft cloth or sponge, with a soft toothbrush for stubborn grease.
Work in small sections. A square metre or so at a time keeps the soap from drying on the surface.
Rinse. Wipe off soap residue with a cloth dipped in plain water, then blot with a dry cloth. Soap left behind can cause its own adhesion problems.
Test first and go easy on moisture. Try the solution on an inconspicuous spot, and never soak the ceiling.
Let it dry completely before priming. Give it a full day if the room is cool or humid.

When to use a commercial degreaser

For a thick, sticky build-up over the stove, a degreaser is faster. The American Cleaning Institute advises following the label, ventilating the room, wearing gloves and eye protection when splashes are possible, and never mixing a degreaser with bleach, ammonia, disinfectants or other cleaners. Their application order is also a good template for a ceiling: remove loose grease with a paper towel or scraper, apply the product, let it sit for the dwell time on the label, scrub with a non-scratch pad if needed, rinse or wipe thoroughly as directed, then dry with a clean cloth.

Open a window or run the range fan while you work, and keep children and pets out of the kitchen until the surface is dry.

Prepare the rest of the surface

Paint makers’ own instructions go beyond washing. The preparation steps on one Canadian stain-blocking ceiling paint page include:

removing loose or flaking paint
treating mildew stains with a mildew stain remover
scuff-sanding glossy surfaces
countersinking nail heads and repairing imperfections, then sanding smooth
removing all dust with a damp cloth and letting the surface dry

If you have dents, cracks or old pot light holes, fill and sand them now. Primer and paint highlight flaws more than they hide them.

Step 3: Prime with a stain-blocking primer

This is the step that decides whether the stain comes back. Behr’s professional team points out that not all primers are created equal: most are designed to improve adhesion and prevent peeling, but not all block stains. You need a primer developed for the type and severity of the stain.

The same guidance suggests:

Stain level	Primer type recommended
Light to medium grease or kitchen stains	A stain-blocking primer and sealer made for kitchens, baths and trim, or a multi-surface stain-blocking primer and sealer
Heavy staining	A restoration-grade stain-blocking primer

For stubborn oil, smoke and heavy stains, a shellac-based primer is the traditional professional choice. The Canadian product page for Zinsser B-I-N says it is recommended for interior ceilings and can block water, grease, rust and smoke stains. One coat usually blocks stains from bleeding into the topcoat, though some stains need a second.

A few practical limits from that page:

Apply only when air, material and surface temperatures are between -18 and 32°C and relative humidity is below 70%.
Do not thin it.
Expect more absorption, and possibly a second coat, on very porous surfaces.

The technical data sheet adds that it dries in minutes and can be recoated in 45 minutes. Shellac primers have a strong odour, so ventilate well and wear the respirator the label calls for. For more on matching a primer to a stain, read our guide to stain-blocking primer in Canada. If the ceiling also carries smoke staining, our smoke damage painting guide explains how sealing works.

Prime more than the visible stain

Grease spreads further than the eye can see. Prime the full area over and around the stove, and spot-prime around light fixtures. If the whole ceiling is dingy, prime the whole ceiling so the sheen is even when you finish.

Step 4: Choose the paint

The best paint for a kitchen ceiling is a stain-blocking ceiling paint with a flat or matte finish. Here is what to look for.

Stain-blocking and mildew resistance

Kitchens combine heat, steam and grease. A Canadian stain-blocking ceiling paint is described by its maker as a stain-blocking paint and primer in one, spatter and drip resistant, low VOC, tintable to light colours and mildew resistant. In the testing mentioned earlier, a stain-blocking ceiling paint showed no bleed-through in two coats, while a generic ceiling flat bled through on the first coat. The same source argues that a better ceiling paint can stretch the repaint cycle to eight to ten years, where cheap flat may need redoing around year four. Treat those as one tester’s results rather than a guarantee, but the direction is clear: spend on the ceiling paint here.

A product that combines paint and primer helps with hiding and adhesion. It does not replace a dedicated stain-blocking primer over heavy grease.

Stain-blocking and mildew resistance

Sheen: flat or matte

Ceilings catch light at a low angle, so a glossy finish exaggerates every roller mark, seam and dent. Designers generally recommend flat or matte for ceilings, because they cut glare and hide imperfections. That source suggests a matte, scrubbable finish specifically for kitchens, where grease deposits and washing are the concerns.

So the choice is simple:

Flat or matte, scrubbable: the default for kitchen ceilings. Hides flaws and tolerates gentle washing.
Satin: only if you want a deliberate contrast on a decorative ceiling. It shows every flaw in the surface.

If you are painting a feature ceiling, we cover sheen and colour in painting coffered ceilings, and the differences between wall and ceiling formulas in ceiling paint vs wall paint.

Colour

White or a very light tint reflects the most light and hides the least. Stain-blocking ceiling paints are typically tintable only to light colours. A slightly warm white avoids the stark look of builder’s white under kitchen lighting.

Step 5: Apply the paint

Ceilings show application mistakes more than walls do. The advice is consistent across sources:

Cut in first. Use a quality angled brush along the walls, crown moulding and light fixtures. One home-improvement writer notes that doing this first saves time and makes rolling smoother.
Use the right roller. A 3/8 to 1/2 inch nap suits most ceilings, from the label of a Canadian ceiling paint. Go to the thicker nap for textured ceilings.
Roll in one direction, in manageable sections, keeping a wet edge so laps don’t show.
Do the last coat toward the main light source. That helps hide roller marks.
Plan on two coats. Ceilings almost always need two, whatever the paint or colour.

Coverage on the product page above is 23 to 37 m² per 3.79 L, depending on texture, porosity and method, so a typical kitchen ceiling takes less than a gallon per coat. Paint when the room and surfaces are between 10 and 32°C. In a Canadian winter, make sure the kitchen is properly heated and not just warmed by the oven.

If the stain still shows

Don’t paint the whole ceiling and hope. Behr’s guidance for heavy stains is to test for bleed-through first: apply the topcoat to a small section. If the stain comes through, spot-prime that area with another coat of primer and test again. If it keeps bleeding, allow a longer dry time before topcoating. More coats may be needed to hide it.

Signs that the stain is not grease at all:

Brown rings with a darker edge: water, usually from a leak above.
Grey or black speckling: mildew, which needs treating before priming.
Soft, bubbling or sagging drywall: a repair job before any paint.

Our water damage wall repair and drywall repair services cover these cases.

Our view from the job site

Most callbacks on kitchen ceilings come down to the same thing: someone painted over a surface that looked clean but wasn’t. The film of oil is nearly invisible until a fresh coat of white makes it obvious.

On our jobs, we treat a kitchen ceiling as a prep job first and a painting job second. We protect the cabinets and floors, degrease and rinse the surface, repair what needs repairing, and then choose a stain-blocking primer to suit what we find. Only then does the finish coat go on. Done in that order, the ceiling is designed to stay clean-looking long after the paint dries.

For homeowners in the GTA, this is also why a fixed, written estimate matters. The prep is where the time goes, and it should be spelled out before the work begins rather than discovered halfway through. We would rather scope it properly, finish on schedule and leave the kitchen spotless than rush the one step you cannot see.

When to hire a professional

A DIY kitchen ceiling is realistic for a small, smooth ceiling with light staining. It gets harder when:

the ceiling is textured, popcorn or very high
the home is older and the ceiling may contain asbestos
there is heavy, sticky grease or smoke staining
the ceiling has water damage, cracks or old pot light holes to repair
you want the cabinets, walls and ceiling to match as one finished room

Get the whole kitchen painted properly

Sigma Painting handles interior painting across the Greater Toronto Area, including ceilings, drywall and water damage repair, with comprehensive prep and cleanup and a complimentary colour consultation. We also offer free, fixed estimates and a written workmanship warranty.

If the ceiling is only part of the project, see kitchen repainting, cabinet painting and interior painting. Cabinets are the other surface that collects cooking grease, and painting them and the ceiling together means one crew, one schedule and one clean finish.

FAQ

Can I just paint over a greasy kitchen ceiling?

Not reliably. Paint does not bond well to oil, and the grease can bleed through and discolour the new coat. Wash the ceiling, let it dry, then seal it with a stain-blocking primer before the topcoat.

What is the best paint for a kitchen ceiling?

A stain-blocking ceiling paint in a flat or matte, scrubbable finish is the usual choice. It hides imperfections, resists spatter and mildew, and holds up better to cooking residue than a generic ceiling flat. Use a dedicated stain-blocking primer first where grease is visible.

What sheen should I use on a kitchen ceiling?

Flat or matte. Low sheen reduces glare and hides seams and roller marks. A matte scrubbable finish suits kitchens because it can be gently washed. Higher sheens show every flaw in the surface.

What cleans grease off a ceiling before painting?

Warm water with a few drops of dish soap works for light grease. For heavier build-up, use a commercial degreaser as its label directs, ventilate the room and never mix it with bleach or ammonia. Rinse with plain water and let the ceiling dry fully.

How many coats does a kitchen ceiling need?

Plan on a coat of stain-blocking primer on greasy areas, then two coats of ceiling paint. Heavy stains may need a second coat of primer, so test a small patch for bleed-through before painting the whole ceiling.
