Why Painting in Place Works Better Than You Think

Removing every cupboard door sounds like the sensible route, but it creates its own problems. You need somewhere to lay out twenty-odd doors, a labelling system so they go back in the right places, and a way to avoid chipping the edges while they sit around for a week. Leaving them on the hinges removes all of that faff and gives you a naturally flat, stable surface to work on.

The trick is understanding what you can and cannot reach. Once a door is dry, you simply open it and paint the inner face — the hinge is already doing the holding for you. Work in a rotation rather than trying to paint both sides at once, and the whole job stays manageable in a normal-sized kitchen.

One honest caveat: if the hinges are worn, the doors are warped, or you want the carcass sprayed to a showroom standard, take them off. For everything else, painting in place is the sensible choice.

Degreasing Is the Step Everyone Rushes

Kitchen units live in a fog of cooking oil. Even a cupboard that looks clean usually carries a thin film of grease, and paint simply will not grip to it. Skip this stage and you will be touching up flaking corners within a year.

Use a proper degreaser rather than washing-up liquid. Sugar soap solution is the traditional choice and works well, but a dedicated kitchen degreaser cuts through baked-on fat faster. Warm water helps, and so does patience.

• Wipe every surface with a well-wrung cloth, working from the top down.
• Give extra attention to the area around the handles, the bottom edge of wall units, and anywhere near the hob.
• Rinse with clean water and let everything dry completely — allow at least an hour in a warm room.
• Go over the surface with a tack cloth to lift any remaining dust.

If the grease is very heavy, degrease twice. It is far quicker than repainting later.

Sanding, Filling and Masking

You are not trying to strip the existing finish, just to give the new paint something to bite into. A light key is all that is required.

• Use 120-grit paper on flat panels, wrapped around a sanding block so you do not round off the edges.
• Scuff the mouldings by hand, following the shape rather than scrubbing across it.
• Fill any dents, screw holes or chipped corners with a fine surface filler, then sand flush once dry.
• Wipe away all dust with a damp cloth, then a tack cloth.

Now mask up. Run low-tack masking tape along the carcass edge where the door meets the frame, and around the inside of the hinge to keep paint out of the mechanism. Push the hinge screws back into their holes or cover them with a scrap of tape — a screw hole full of paint is a maddening thing to deal with later. Take the handles off if you can, and bag the screws.

Priming and Painting for a Factory-Style Finish

This is where the foam roller earns its keep. A dense foam roller leaves almost no texture, which is exactly what you want on a flat cupboard door. Mini rollers around 100mm are ideal for the width of most doors.

Start with a bonding primer or a shellac-based stain blocker if the old colour is dark or the units are knotty. One thin coat is usually enough, applied with the roller and laid off with a brush at the edges.

For the topcoats, choose a water-based satin or eggshell designed for trim and cupboards. Water-based paint dries quickly, stays whiter for longer, and is far less smelly in a working kitchen.

• Load the roller lightly and roll it out on a tray until it stops dripping.
• Apply two thin coats rather than one thick one. Thin coats level out and resist runs.
• Work in sections of about a metre, keeping a wet edge so you do not get lap marks.
• Roll vertically, then gently lay off top to bottom with almost no pressure to knock out bubbles.
• Do the inner faces on a separate day so you never handle a wet front.

Keep the room at around 18–22°C with the window cracked for airflow, and give each coat at least four hours before recoating.

Curing, Refitting and Looking After the Finish

Water-based paint feels dry within hours but is not yet hard. Resist the urge to slam doors shut or scrub anything for at least a week. Full cure typically takes five to seven days, and in cooler, damper conditions it can take longer.

Refit handles and knobs after 24 hours, tightening the screws gently — over-tightening on fresh paint can crack the film. Where you have painted around the hinge, score the paint line lightly with a craft knife before opening and closing the door for the first time, so it does not tear.

For ongoing maintenance, clean with a soft cloth and mild soapy water. Avoid abrasive creams and solvents, which dull the sheen. Touch up small chips with a fine artist's brush and a dab of leftover paint kept in a labelled jar — you will be glad you did.
