What skimming a ceiling involves

  1. 1
    Assess the ceiling

    A sound ceiling can be skimmed directly; a cracked, artexed or lath-and-plaster ceiling is usually overboarded first.

  2. 2
    Skim coat

    A thin plaster finish coat is applied and trowelled flat for a paint-ready surface.

  3. 3
    Dry and paint

    Fresh plaster dries in a few days to an even pale colour, then it's misted and painted.

A crisp, flat white ceiling quietly lifts a whole room, while a cracked or artexed one drags it down. Skimming is cheap per m²; the decision that moves the cost is whether to overboard first — and on tired ceilings, it usually pays to.

Frequently asked questions

How much does it cost to skim a ceiling?+

Skimming a sound ceiling costs £15–£30 per m², so a room ceiling (~12 m²) is roughly £180–£360. Overboarding first (for cracked, artexed or lath ceilings) costs £25–£45 per m².

Should I overboard or skim a ceiling?+

If the ceiling is sound and flat, skim it directly. If it's cracked, sagging, artexed or old lath-and-plaster, overboarding gives a stronger, flatter, safer result — worth the extra per m².
