Decorating after an extension or other building work

Newly plastered wall left to dry before decorating begins on a building project

Decorating too early on a building project usually means redoing it once other trades finish behind you. New plaster needs real drying time, joiners and electricians often still need wall access for first and second fix, and dust from ongoing work can settle into wet paint before it cures.

Questions we are asked about this

How long should new plaster dry before painting?

It varies with the room's ventilation, heating and the season, so we check the plaster's condition directly rather than working to a fixed number of weeks that might not suit your specific site.

Should decorating happen before or after skirtings are fitted?

Generally after skirtings and architraves are fitted and caulked, so the final wall coats can be cut in cleanly against them rather than needing touch-ups once carpentry is complete.

Can decorators work alongside other trades still finishing the build?

To some extent for early stages like mist coats, but final coats are best scheduled once the dustiest remaining trades are done, to avoid finished work being contaminated.

New plaster needs time before it will take paint properly

Fresh plaster is porous and can take considerably longer to dry fully than it appears, particularly in colder months or poorly ventilated rooms. Painting too soon traps moisture and often leads to a patchy or flaking mist coat within weeks. We check the plaster's readiness rather than working to an assumed number of weeks.

Coordinating around other trades still on site

If electricians still need to chase walls or a joiner has skirtings and architraves to fit, decorating those walls first means either working around unfinished trades or repainting once they are done. We ask what stage other trades are at before booking decorating, so the sequence actually works.

  • First and second fix confirmed complete before final decorating begins
  • Skirtings and architraves fitted and caulked before final wall coats
  • Floor protection agreed with other trades still moving materials through the space

Dust control during the final stages of a build

Even once the messiest work is done, ongoing cutting, sanding or fitting elsewhere in the property can send dust through a finished room. We time final coats for after the dustiest remaining work and use barriers to protect newly painted areas where other trades are still active nearby.

  • Final coats scheduled after the last significant dust-generating work
  • Barriers used to protect finished rooms from adjacent ongoing trades
  • A snagging walk done once all trades, including decorating, are complete

How we work on this

  • We check new plaster's actual dryness rather than working to an assumed drying period
  • We confirm other trades' progress before booking final decorating on a build
  • We protect finished rooms with barriers where other trades remain active nearby

Tell us your build programme and we will slot decorating into the sequence at the right point, not too early.

Decorating after building work only holds up when it is sequenced properly around plaster drying and other trades.
