You can spend a whole weekend painting kitchen cabinets, or send a crew in to knock it out on a tight remodel schedule, and the result can still go sideways fast. At first, everything looks great. The color feels fresh. The space looks better right away. Then a few months pass, and the paint starts chipping near the handles. The corners begin to wear, and the job does not look so good anymore.
That is frustrating for anyone. Homeowners feel like they wasted time and money. And for contractors, it can lead to callbacks and unhappy clients. Most of the time, the paint is not the issue. The real problem starts before the first coat goes on.
In this guide, we’ll go through the prep steps that help paint hold up. You’ll learn why prep matters and which tools you need to prepare cabinets for painting.
Why Prep Work Makes or Breaks a Cabinet Paint Job
Paint needs a surface it can grip. If your cabinets feel slick, glossy, or dusty, that grip never forms. The paint may look smooth at first. After daily use, it starts to break down. Many issues show up within the first 6 to 12 months after painting.
Kitchen cabinets deal with more use than most painted surfaces in the house. Hands touch them all day. Steam hits them near the sink and dishwasher. Cooking oils settle near the range. That leaves an invisible grease film that blocks adhesion.
Even the best primer for cabinet painting cannot fix a dirty or shiny surface. Prep gives paint a clean base and a slight texture to hold onto. That is what leads to better adhesion and a result that lasts longer.
Tools and Supplies Checklist Before You Start
Before you start any cabinet painting prep steps, gather everything in one place. That will help you avoid mid-project store runs.
Cleaning and Prep Supplies:
- TSP, TSP substitute, or a kitchen degreaser for cutting grease before sanding.
- Microfiber cloths or lint-free rags for wiping and drying.
- Mild dish soap and warm water for a first pass or quick spot cleaning.
- Painter’s tape. FrogTape is a favorite for clean lines.
- Drop cloths for floors, counters, and appliances.
- Screwdriver or cordless drill for removing doors and hardware.
- Labeled plastic bags for screws, hinges, knobs, and pulls.
Sanding and Priming Supplies:
- 150-grit sandpaper for the first scuff. Just enough to knock the surface back.
- 220-grit sandpaper for smoothing things out, especially after filler or primer.
- Foam sanding block or sponge. Much easier on edges and detailed spots.
- Tack cloth to pick up dust.
- Wood filler or spackle for nail holes, dents, and chips.
- A good primer matched to the surface. Shellac-based for oak or anything that bleeds. Bonding primer for laminate or MDF. Latex works fine on painted wood that’s still in good shape.
- Foam roller and an angled brush.
- Roller for the flat areas.
- Brush for corners and trim details.
How to Prep Cabinets for Painting, Step by Step
Step 1. Clear and Protect Your Workspace
Start by getting the room ready:
- Empty every cabinet and drawer.
- Remove shelf liners.
- Take small appliances off the counters.
You want clear access to every box, face frame, and panel.
Next, cover what stays in the room. Lay drop cloths over the floor. Protect countertops and appliances. Tape off the wall edges, backsplash, and any trim that will not get painted. This part saves a lot of cleanup later.
A clean work zone helps in another way too. Cabinet prep creates dust. Sanding sends fine particles everywhere, and those particles love to settle into wet primer and paint. A tidy setup cuts down on that mess.
Here is a smart extra step. Cover nearby HVAC vents before you sand. That keeps dust from moving through the house and reaching other rooms.
Step 2. Remove Doors, Drawer Fronts, and All Hardware
If you want a smooth cabinet finish, take the doors off. Use a screwdriver or a drill on a low setting to remove each door from its hinges. Remove drawer fronts if your cabinet style allows. Also, remove knobs, pulls, and hinges from the doors.
Now, label everything. If you don’t do it, you’ll have trouble reinstalling it all. Use a pencil and write on the back of each door. A simple code works well, such as “sink left” or “upper 3.” Write inside the hinge cup area or hinge recess so the mark stays hidden later. Put matching screws and hardware into a labeled plastic bag.
Cabinet openings can look almost identical once all the doors are off. Ten minutes of labeling can save an hour of guessing.
One note for European hinges. If the hinge base plates stay on the cabinet box and are hard to reset, tape them off and leave them in place. Re-adjusting them later can be an issue.
Step 3. Deep Clean All Surfaces
This is the step people rush, and it is often the step that causes peeling later. Degreasing kitchen cabinets before painting gives the primer a clean surface to bond to.
Use TSP or a TSP substitute for a milder option. It is a strong cleaner found in the paint aisle. Mix it with water based on the label. Put on gloves. Then scrub every paintable surface. Clean the front and back of each door. Clean drawer fronts, face frames, side panels, and toe kicks.
Pay close attention to the spots around handles, near the stove, and above the range. Those areas collect the most grease from hands and cooking. They may look clean, yet they often still have oil on them.
After scrubbing, rinse the cabinets with clean water and wipe them dry with microfiber cloths. Let everything dry fully. A final wipe with glass cleaner can help remove any remaining hand oil before sanding.
Many people stop at dish soap and warm water. That sounds reasonable. It usually is not enough for kitchen cabinets. Soap can clean visible grime, yet it often leaves behind the thin grease film that causes adhesion problems.
Step 4. Sand the Surfaces
Once the cabinets are clean and fully dry, it is time to sand them. You are not trying to strip them to bare wood. Just remove the old finish. This way, the primer has something to grip.
For the first pass, use 150-grit sandpaper:
- Sand with the grain on wood doors and frames.
- Use a foam sanding block on flat areas.
- Fold the paper for grooves, corners, and shaped profiles.
- Keep your pressure light, mainly on edges. Heavy sanding rounds corners.
When you finish the first pass, clean up all the dust. Vacuum everything, then wipe the surfaces with a tack cloth or a slightly damp microfiber cloth. Dust left behind can ruin a smooth finish.
For this stage, follow a simple routine: clean first, sand with 150-grit, prime, sand again with 220-grit, then paint. That second sanding step is one of the easiest ways to get a softer, more polished look.
Step 5. Fill Holes, Cracks, and Imperfections
Small flaws stand out more after being painted on, mainly with light colors. A tiny dent can turn into a shadow line once the surface is coated. That’s why it’s important to inspect each piece carefully.
Use wood filler on nail holes, scratches, and any holes from old hardware. Apply it with a putty knife and press it in firmly. Let it dry all the way based on the product label. Once dry, sand it flush with 220-grit sandpaper. Wipe off the dust again. A clean surface matters at every stage.
If you plan a style change, this step becomes even more useful. Say you want a clean painted look similar to White Shaker Cabinets. Old knob holes or worn corners will stand out unless you fix them first.
Step 6. Choose and Apply Primer
Primer helps create a good bond between your cabinet surface and the paint. If you skip using primer, your painted kitchen cabinets may look fine for a little while. Then, you’ll notice chips.
Pick the primer that matches the cabinet material. Solid wood cabinets, especially oak or cherry, usually do best with a shellac-based primer. Those woods can bleed through paint. You’ll see yellow or brown stains even after a fresh coat if the surface isn’t sealed properly.
Laminate and MDF need a bonding primer. These surfaces feel slick, so they need a product made for low-porosity materials. Previously painted wood in good shape can often use a quality latex or water-based primer.
Lay the primer on in thin, even layers. A foam roller works well on the flat parts, and an angled brush gets into grooves and trim. Watch for drips on the lower edge of doors and along frame joints. Let the primer dry fully. Once dry, sand lightly with 220-grit sandpaper, then remove any remaining dust.
Signs It’s Time for New Cabinets
Sometimes paint helps. Sometimes it only covers up a bigger issue.
Inspect your cabinets:
- Check the cabinet boxes first. If they are warped, swollen from water, or pulling apart at the joints, paint will not fix them.
- Same, if the doors are coming apart, the laminate is peeling, or the drawers are sticking and sagging.
- And if the kitchen layout does not work well, a new color will not change that.
At that point, replacement may be a costly but better option. If the cabinet structure is still in good shape, painting can be a smart update. If the boxes are failing, new cabinets can save you from having to redo the job.
Summing Up
A cabinet paint job lasts or fails long before the finish coat goes on. Clean the grease off first. Sand the sheen down. Fix the dents. Use the right primer for the surface in front of you. Those steps are what keep paint from chipping near handles and wearing off at the corners.
If the cabinet boxes are still solid, take your time with prep. It shows in the finish, and it lasts. If they’re worn out or the layout no longer works, it may be worth stepping back and looking at replacement.

Frequently Asked Questions
What’s the best cleaner to use before painting cabinets?
TSP or a TSP substitute is the go-to. It cleans grease better than dish soap. Clean it, rinse it well, and let everything dry before you touch sandpaper.
How long does it take to prep cabinets for painting?
Plan on a couple of days. Two to three is typical. The first day usually goes to cleaning, taking things apart, and filling dents or holes. The next day is sanding and primer, plus drying time. That part always takes longer than you think.
Can I paint over already-painted cabinets without sanding?
You can reduce sanding if the old finish is still in good condition and you use a bonding primer. But don’t skip it completely. A quick scuff helps the new paint stick.
Should I paint cabinet doors on or off the cabinet?
Take them off. It’s just easier. You get a smoother finish on a flat surface, and you won’t fight drips along the frame. It also lets you prep the edges.
