Ceiling painting, the surface light is cruellest to

What is ceiling painting?

Ceiling painting is the preparation and coating of the overhead plane, usually in a flat finish specifically chosen to disguise imperfection. It is harder than wall painting for one reason: ceilings are lit from the side, so every lap mark, patch and texture change catches light and stays visible. A ceiling has to be painted in one continuous session, wet edge maintained, or the joins show permanently.

Signs you need ceiling painting

• A brown or yellow water stain has appeared, usually in a corner or around a light fitting
• The ceiling has yellowed overall, most commonly in kitchens and in rooms where people smoked
• Repaired areas or new drywall patches are visible as dull or different-textured patches
• Hairline cracks have opened along the joint between ceiling and wall
• Popcorn or textured finish is dated, damaged, or shedding
• Previous touch-ups have left obvious patches that look worse than the marks they covered
• You are repainting the walls and the ceiling is visibly dingier than the new wall colour

How ceiling painting actually works

1. 1

   Establishing whether the stain source is fixed

   A water stain is evidence, not a decorating problem. Before anything is coated, whoever is doing the work should know whether the leak that caused it has been repaired and whether the drywall above is sound.

   Watch forPainting a stain whose cause is unknown. The stain will return, and by then it will have a fresh coat of paint on it to bleed through.

2. 2

   Blocking stains properly

   Water stains and nicotine bleed through ordinary paint. They need a stain-blocking primer applied to the affected area - sometimes to the whole ceiling where the discolouration is general.

   Watch forExtra coats of ceiling paint used instead of a blocking primer. It genuinely does not work; the stain comes back through, occasionally within days, and you will be repainting the whole ceiling.

3. 3

   Protection and access

   Everything below is covered - ceilings drip. Light fittings are dropped or removed, ceiling fans dealt with, and access set up so the painter can move continuously without stopping to reposition.

   Watch forAccess that requires the painter to stop and move a ladder repeatedly across a large ceiling. That is how lap marks get built in, because the wet edge dries during the interruption.

4. 4

   Repairs, filling and texture matching

   Cracks are opened and filled, nail pops fixed, and any patch is finished and, on a textured ceiling, texture-matched. Matching existing texture is a specific skill and it is rarely perfect.

   Watch forA smooth patch left in a textured ceiling. Painting over it makes it more visible, not less, because the flat area reflects light differently from everything around it.

5. 5

   Cutting in and rolling wet-edge

   The perimeter is cut in and the field rolled in a continuous sequence, each pass overlapping the previous one while it is still wet. A helper or a fast worker matters here more than on any other surface.

   Watch forA ceiling painted in sections across a break - a lunch stop, or moving furniture halfway. The dry join between sections shows under side light and cannot be fixed by touching up.

6. 6

   Second coat

   Most ceilings need two coats, particularly over a blocked stain or a colour change. The second coat is what evens out the sheen and hides the first coat's variation.

   Watch forOne coat over a primed stain. The primer patch will read as a slightly different sheen through a single finish coat, which is exactly the thing you were trying to remove.

7. 7

   Inspection under working light

   The ceiling should be inspected with the room's actual lighting on and, separately, in daylight. Defects appear under one and not the other.

   Watch forSign-off with a work light pointing at the ceiling. Work lights flatten the very shadows that reveal lap marks. Look at it the way you will live with it.

What does ceiling painting cost?

Ceilings are usually priced per room or per square foot and are cheaper than walls per unit area, since there is no cutting around windows or doors - but stain blocking, texture repair and high or vaulted ceilings all add. See the Cost Guide for ranges.
