Can I paint over old kitchen cabinets without prepping? No, you cannot skip prepping if you want your new paint job to look good and last a long time. Good prep work is the most important part of painting cabinets. It makes sure the paint sticks well. This guide shows you simple steps to get your cabinets ready for a great paint finish.
Why Proper Preparation is Key to Cabinet Painting Success
Many people rush this part. They think painting is the main job. It is not. Prepping the cabinets is the key. If the surface is not clean, smooth, and primed, the paint will peel, chip, or look bumpy. Taking the time to properly prepare your cabinets saves you headaches later. Great results come from great prep work.
Setting Expectations for a Long-Lasting Finish
A quality paint job on cabinets can last for many years. This lasts because of the careful work done before the paint touches the wood. We are aiming for a factory-like finish. This requires patience and attention to small details.
Step 1: Clearing the Area and Removing Cabinet Doors
Before touching the cabinets, you must clear the kitchen. Remove everything from the counters and inside the cabinets. This makes a clean workspace.
Removing Hardware and Doors
You need to take off the handles, knobs, and hinges. Lay them out neatly. Label them so you know where they go back. This step is crucial.
Cabinet door removal for painting is best done outside of the kitchen if possible. Place doors flat on sawhorses in a well-ventilated area. If you cannot remove the doors, you must take extra care when working around hinges and edges.
Action Items for Door Removal:
- Keep all screws in small bags.
- Label the back of each door (e.g., “Top Left Door”).
- Store hardware safely away from dust.
Protecting Surrounding Areas
Cover floors, counters, and appliances with plastic sheeting or drop cloths. Use painter’s tape to secure the edges. This protects surfaces from dust and paint splatter.
Step 2: Deep Cleaning: Degreasing Kitchen Cabinets
Kitchen cabinets get greasy. Grease, cooking oil, and grime build up over time. If you paint over grease, the paint will not stick. It will bubble or peel off quickly. Degreasing kitchen cabinets is a non-negotiable step.
Choosing the Right Cleaner
You need a strong cleaner. Simple dish soap might not cut through heavy grease. TSP (Trisodium Phosphate) is very effective, but it is harsh. A good alternative for most homes is a strong degreaser or a mix of warm water and a strong household cleaner.
DIY Degreasing Solution:
- 1 gallon of warm water
- 1/2 cup of powdered TSP substitute (or a strong cabinet degreaser)
- A few drops of dish soap
The Cleaning Process
Always wear gloves and eye protection when using strong cleaners.
- Dip a soft sponge or cloth into the solution. Wring it out so it is damp, not soaking wet.
- Wipe down every surface of the cabinet frames and doors. Pay close attention to areas near the stove and under handles.
- Rinse the cabinets well. Use a new cloth dipped only in clean water. This removes any cleaner residue. Cleaner left behind will stop the paint from sticking.
- Allow the cabinets to dry completely. This might take several hours. Use fans to speed up the drying time.
This thorough process ensures you are cleaning wood cabinets for paint correctly, removing all dirt and oils.
Step 3: Repairing Cabinets Before Painting
Now that the cabinets are clean and dry, look closely for damage. This is the time to fix cracks, chips, or holes. Repairing cabinets before painting creates a smooth canvas.
Fixing Dents and Holes
Small holes, like those left from old hardware, need filling. Use a good quality wood filler or spackle.
Filling Cabinet Holes Before Painting:
- Press the filler firmly into the hole with a putty knife.
- Wipe off the excess filler immediately. You want the filler level with the cabinet surface.
- Let the filler dry completely. Drying times vary based on the product.
- Once dry, sand the filled area smooth. It should feel seamless with the surrounding wood.
Check for loose joints or wobbly cabinet faces. Tighten any screws. If there are deep gouges, you may need wood epoxy for a strong repair.
Dealing with Glossy or Shiny Finishes
If your cabinets have a very glossy factory finish (like laminate or high-gloss paint), you must dull this surface. You can use a chemical deglosser product. Alternatively, heavy sanding cabinets before painting will scratch the surface enough for the primer to grab onto.
Step 4: Prepping for Paint Adhesion: Sanding and Priming
This step is where many DIY painters fail. Proper surface texture is vital. Think of it like preparing skin before applying makeup.
Sanding Cabinets Before Painting: Choosing the Right Grit
Sanding cabinets before painting creates “tooth”—a microscopic texture that paint adheres to. Do not use sandpaper that is too rough, or you will leave deep scratches.
Best Sandpaper Grit for Cabinets:
| Stage | Grit Size | Purpose |
|---|---|---|
| Initial Sanding (Glossy or Damaged) | 120 – 150 grit | To break the shine and remove minor imperfections. |
| Final Sanding (Before Primer) | 180 – 220 grit | To smooth the surface after repairs and deep cleaning. |
| Light Scuff Sanding (Between Coats) | 220 – 320 grit | To gently smooth cured primer or previous paint coats. |
Use an orbital sander for large, flat areas to save time. Use sanding sponges or sanding blocks for corners and edges. Always sand with the grain of the wood.
Dust Removal After Sanding
Dust is the enemy of a smooth paint job. After sanding, clean every surface thoroughly.
- Use a shop vacuum with a soft brush attachment to remove large dust particles.
- Wipe down all surfaces with a tack cloth. A tack cloth is a sticky cheesecloth. It picks up the fine dust that the vacuum misses. Do this multiple times until no dust transfers to your hand.
Should I Strip Cabinets for Paint?
Stripping cabinets for paint is usually only necessary if the existing finish is failing badly, chipping, or if you are dealing with very thick, old layers of oil-based paint that sanding cannot fully remove. For most modern, well-maintained cabinets, aggressive sanding and good primer are enough. Stripping is messy and labor-intensive, so try to avoid it unless absolutely necessary.
Step 5: Priming Kitchen Cabinets Correctly
Priming kitchen cabinets is the bridge between the old surface and the new paint. Primer seals the wood, blocks stains, and gives the topcoat something solid to stick to. Never skip primer, especially when painting wood or laminate.
Selecting the Right Primer
The type of primer matters based on what you are painting over:
- Oil-Based Primer (Alkyd): Excellent stain-blocking. Great for bare wood or cabinets with lots of knots that might bleed through. It smells strong and dries slowly.
- Shellac-Based Primer: The best stain blocker available. Use this if you have water stains or are painting over wood that bleeds tannins (like cedar or redwood). Dries very fast.
- Bonding Primer (Specialty Acrylic): Ideal for slick surfaces like laminate or metal where adhesion is a major concern.
Use primers specifically labeled for cabinets or trim, as these usually dry harder than standard wall primers.
Applying the Primer
Apply primer just as you plan to apply the final paint—thin, even coats.
- Brush/Roller Application: Use a high-quality angled brush for corners and a small, high-density foam roller for flat surfaces.
- Spray Application: If you are spraying, follow the manufacturer’s instructions carefully for distance and speed. Spraying gives the smoothest finish but requires excellent ventilation and masking.
Apply the first coat evenly. Let it dry completely as directed on the can.
Sanding Between Primer Coats
After the first coat of primer dries, the surface might feel slightly rough. This is normal. It is called “raising the grain” on wood or just showing minor imperfections.
Lightly sand the primed surface using fine sandpaper (220 grit or higher). The goal is not to remove the primer, but to just knock down the rough spots. Wipe away all dust with a tack cloth.
Apply a second coat of primer if needed, especially if you are making a drastic color change (e.g., dark brown to white). Repeat the light sanding and dusting.
Step 6: Painting Techniques for a Professional Look
With the cabinets prepped, sanded, and primed, you are ready for the topcoat. The painting technique is as important as the prep work.
Paint Choice Matters
Use high-quality cabinet paint. Standard wall latex paint is too soft and will scratch easily. Look for durable finishes like:
- Cabinet-Specific Acrylic Enamels: Offer good durability and flow well.
- Oil-Modified Alkyd: Very hard finish, but yellowing can occur over time, especially in white colors.
- Urethane or Hybrid Enamels: Known for their excellent durability and leveling properties.
Application Methods
The application method drastically affects the final look.
Brush and Roller Method
This is accessible for most DIYers.
- Use an angled sash brush for cutting in edges and grooves.
- Use a small, high-density foam roller (1/4 inch nap or less) for flat panels.
- Apply thin coats. It is better to apply three thin coats than one thick coat. Thick coats sag and show roller marks.
- Work quickly but methodically. Let the paint self-level between brush strokes as much as possible.
Spraying Method (For Smoothest Finish)
Spraying, using an HVLP (High Volume, Low Pressure) sprayer, delivers the closest look to a factory finish.
- This requires meticulous masking of all surrounding areas (walls, floors, inside the cabinet boxes).
- Maintain consistent speed and distance from the surface.
- Apply in light, overlapping passes.
Recoating and Final Curing
Wait for the first coat of paint to dry fully before applying the second. Check the can for recoat times. Forcing it can ruin the adhesion.
After the final coat, you must wait for the paint to cure. Drying time is when the paint is touch-dry. Curing time is when the paint reaches maximum hardness. Cabinet paint often takes 7 to 30 days to fully cure. Be gentle with the cabinets during this time. Avoid slamming doors or heavy scrubbing.
Prepping Cabinet Boxes vs. Doors
While the general process remains the same, cabinet boxes require slightly different handling.
Working on the Cabinet Boxes
When preparing cabinets for refinishing the boxes, you often cannot remove the entire box structure.
- Protect the Interior: Use painter’s tape to fully cover the inside shelves and drawer opening edges.
- Working Around the Frame: You will use more brushing here. Use a good brush to ensure the paint gets into the corners where the face frame meets the box sides.
- Rollers in Tight Spots: Use the smallest foam rollers possible for the interior sides of the cabinet boxes.
It is often easier to tackle the boxes first, let them dry completely, and then work on the doors while the boxes are untouched.

Frequently Asked Questions (FAQ)
Q: How long does the entire cabinet prepping process take?
A: For an average-sized kitchen (15-20 doors/drawers), the prep process—cleaning, repairing, sanding, and priming—can easily take 3 to 5 full days. This time includes required drying periods between steps, which you cannot rush.
Q: Can I use steel wool instead of sandpaper?
A: You can use fine grade steel wool (#000 or #0000) for very light scuffing between coats of primer or paint, especially on detailed molding. However, steel wool leaves tiny metal fibers behind. If these fibers remain, they can rust when exposed to moisture or chemicals, causing spots on your paint job. It is safer to stick to high-quality sandpaper and tack cloths.
Q: What should I do if the existing cabinet finish is peeling?
A: If the existing finish is flaking or peeling, sanding alone is not enough. You must remove all loose material first. Use a paint scraper or a chemical stripper if the peeling area is large. This is where the concept of stripping cabinets for paint becomes necessary. Once the loose material is gone, you must sand the edges of the remaining finish smooth so there is no harsh transition line before you proceed with priming kitchen cabinets.
Q: Is it necessary to remove drawers and doors?
A: Yes, for the best results, you should remove them. Painting doors and drawers laid flat ensures even coverage without drips or runs on the edges or hinges. It allows you to properly handle the sanding cabinets before painting process on all sides without fighting the cabinet box structure.
