What Preparation Is Needed Before Respraying Kitchen Cabinets?

Before kitchen cabinets are resprayed, every surface is degreased, sanded to give a key, filled and repaired, then coated with an adhesion primer that suits the material. Doors and drawer fronts come off and are labelled, and worktops, floors and appliances are masked. Preparation decides whether the finish lasts for years or starts lifting within a year or two, which is why a professional spends more time preparing a kitchen than spraying it.

This guide covers what happens to your kitchen before the colour goes on. If you are still checking whether your doors are suitable at all, start with which kitchen cabinet materials can be resprayed.

Why Does Preparation Matter So Much?

Kitchen cabinets collect years of cooking grease, silicone from sealants and wax from cleaning sprays. You cannot see most of it, but it stops paint bonding. A topcoat sprayed over contamination does not fail straight away. Within 12 to 24 months it starts lifting at the edges, peeling or chipping at the slightest knock. When we are asked to put right a failed respray, poor degreasing is usually the cause.

The coating system matters, but it cannot make up for a badly prepared surface. Good paint on a contaminated door will fail; a properly prepared door gives any good coating the best chance of lasting.

Step 1: Door Removal and Labelling

All doors and drawer fronts come off and are numbered so each one goes back in exactly the same place. Handles, hinges and fixings are removed too. Masking around hardware gives a poorer edge and makes the doors harder to clean later. At ColourHaus the doors and drawer fronts are usually taken to our Sheepscar workshop in Leeds to be sprayed, while frames and end panels are prepared and sprayed in place.

With the doors off, the cabinet frames, carcass edges and any visible inside faces can be cleaned and treated properly. People often forget these surfaces, but you see them every time you open a cupboard.

Step 2: Degreasing

Every surface to be sprayed is cleaned with a specialist degreaser, not washing-up liquid or a kitchen spray. Trade degreasers cut through baked-on cooking grease, silicone and polish residue. The work is done section by section and repeated wherever contamination remains.

This takes longer than most people expect. A busy family kitchen that has been cooked in every day for ten years can take an hour or more to degrease on its own. Rushing this step is the most common shortcut, and the most costly one in the long run.

Step 3: Sanding

Once clean and dry, every surface is sanded to give the primer a mechanical key, something to physically grip. The grit depends on the material: smooth MDF needs a finer grit than open-grained timber, and laminate and high-gloss doors need thorough keying because their surfaces are non-porous. Sanding also levels small imperfections.

All dust is then removed with a tack cloth. Dust left on the surface gets trapped in the primer and shows as a gritty texture in the final finish.

Step 4: Filling and Repairs

Chips, dents and damage are filled with a suitable filler, left to cure fully and sanded flush, so the surface is smooth before primer goes on. Loose edges and small areas of lifted veneer are glued down and repaired at the same stage.

Spray painting cannot hide structural damage. Deep gouges, doors that are delaminating across the whole face, or MDF that has swollen from water need repairing or replacing before any cosmetic work. We point these out at the survey.

Step 5: Adhesion Primer

Adhesion primer bonds the colour coats to the prepared surface. It seals the material, stops anything bleeding through from underneath and gives a uniform base for colour. There is no professional kitchen respray without it.

Different materials need different primers. Laminate, high-gloss and vinyl-wrapped doors need primers made for non-porous surfaces, while wood and MDF take a different type. The wrong primer for the material is almost as bad as none, which is one reason the survey checks what your doors are made of.

Once the primer has cured, it is inspected and lightly sanded to remove any dust nibs before the colour coats. The doors then get two topcoats applied with HVLP (high volume, low pressure) spray equipment.

When Is Laser Stripping Needed?

Some doors need more than standard preparation. The two common cases are doors that have been brush- or roller-painted many times and carry a heavy, uneven build-up, and vinyl-wrapped doors where the wrap is lifting or peeling.

In both cases, new paint over the old surface will not last: the old layer keeps moving and takes the new finish with it. Laser stripping uses a pulsed laser to lift old coatings without chemical strippers or sanding, and it is one of the ways we take a door back to a clean surface. Like any stripping method, it is quoted after a free assessment, because the time it takes depends on the area and how many layers there are. Our guide to laser stripping before respraying covers it in more detail, and our post on whether you can spray over existing paint explains how we decide what has to come off.

What Happens to the Frames and Carcasses?

While the doors are prepared and sprayed at the workshop, the frames, end panels and any carcass faces that will be sprayed are cleaned, sanded and primed in place. Worktops, appliances, walls and floors are masked. Good masking is precise and comes off cleanly without leaving adhesive behind.

“Really impressed with the service and results. Our job was non standard but Matt found a solution and the results were excellent. George was incredibly detailed in his preparation.”

How Long Does Preparation Take?

It depends on the number of doors, how much grease and damage there is, and whether anything needs stripping or repairing. Preparation is part of the 3 to 5 working days most kitchen resprays in Yorkshire take, and on most kitchens it takes more of that time than the spraying itself. Your fixed written quote sets out the schedule. The same preparation applies when we spray fitted wardrobes and furniture, and if you want worktops, tiles and walls done alongside the units, that is a whole-room kitchen makeover.

Frequently Asked Questions

Why is preparation so important for a kitchen respray?

Preparation decides whether a respray lasts for years or starts failing within a year or two. Grease, silicone and polish residue left on the surface stop primer bonding. A finish that peels early almost always traces back to poor degreasing or a missing adhesion primer.

What is adhesion primer and why is it needed?

Adhesion primer bonds the colour coats to the prepared surface and seals it. Without it, even well-cleaned and sanded doors will not hold the topcoat reliably. Every professional kitchen respray uses at least one coat of a primer suited to the door material.

How long does the preparation stage take?

It depends on the number of doors, the condition of the kitchen and whether anything needs stripping or repairing. Preparation is part of the 3 to 5 working days most kitchen resprays take, and it usually takes more of that time than the spraying.

Can I do the preparation myself to reduce the cost?

We do not recommend it. Professional preparation uses trade degreasers, the right abrasives and the right primer for each material. Household cleaners do not reliably remove silicone and wax, and if the preparation fails, the new finish fails with it.

When is laser stripping needed before a respray?

When doors carry a heavy build-up of old brushed paint, or vinyl wrap that is lifting. New paint over either will not last. Laser stripping takes the old coating off without chemicals or sanding, and it is quoted after a free assessment.
