Plasterboard Painting Services
New Plasterboard First Coat
New plasterboard has a paper face that absorbs emulsion unevenly. A diluted sealing coat is applied first to reduce suction uniformly. Once dry, full-strength topcoat follows.
Freshly Skimmed Walls
Fresh gypsum skim is alkaline and draws moisture from paint. A sealing coat normalises the suction. See our ceiling painting service for plasterboard ceilings.
Plasterboard Patching
Where building works have disturbed plaster, the new section needs sealing and blending with the surrounding surface. The suction levels differ significantly.
Extensions and Loft Conversions
We paint new rooms as part of a wider programme. For full renovation, see our home renovation and interior painting pages.


Here’s How It Works
1. Surface Assessment
We check if plasterboard or skim is fully dry. We note tape joints and suction variation.
2. Sealing Coat
Diluted emulsion or specialist sealer applied to the full surface to normalise suction.
3. Inspection After Drying
Surface checked for any remaining tape joint visibility. Additional prep if needed.
4. Topcoat Application
Two finish coats of the specified emulsion in the standard sequence.
5. Check and Inspection
All surfaces checked in raking light before we leave.
