Plasterboard Painting in Richmond

Richmond Decorators covers plasterboard painting across London and Richmond upon Thames, from Twickenham and Hampton to Teddington and East Sheen.
- New plasterboard walls with a sealing coat system for even absorption
- Skim-coated surfaces with the correct primer before finish coats
- Extension and loft interiors with full preparation from first fix through to finish
- Plaster repair and patchwork, filled, sanded, and primed before painting
- Ceilings with a consistent two-coat finish on new plasterboard
Twickenham Victorian terraces around King Street frequently have single-storey kitchen extensions built with plasterboard walls. Joints and scrim are visible through a direct finish coat unless properly filled, sanded, and skim-coated. Some trade decorators skip this step under price pressure. Your decorator does not.

Plasterboard Painting Services
Your decorator can assess drying readiness and propose the preparation and finish-coat sequence for the plasterboard scope. Your decorator records the proposed preparation and finishes sequence in the written quote.


Freshly Plastered Walls
New plaster is highly alkaline and absorbs paint unevenly. Applying standard emulsion directly onto fresh plaster results in a patchy finish and paint failure.
Your decorator checks drying readiness before painting new plaster. Colour alone does not establish whether plaster is ready for coating; your decorator assesses it for the selected system.
Sealing Coat Application
A sealing coat is a diluted emulsion that penetrates new plaster without sitting on the surface. It regulates absorption so that subsequent finish coats lay evenly.
Your decorator mixes the correct ratio based on the absorbency of the plaster. Plasterboard with a skim coat behaves differently from bare board, and your decorator assesses and adjusts accordingly.
First and Second Fix
On new builds and extensions, painting can take place in two stages. An initial stage may be completed before joinery and fixtures are installed.
Second fix is the finish work around installed joinery, sockets, and switches. Your decorator works to the building programme where required.
New Build and Extension
Extensions in Richmond and the surrounding borough are common. Rear kitchen extensions in Twickenham, side-return extensions in Barnes SW13, and loft conversions in Hampton TW12 all follow the same plasterboard painting process.
Your decorator coordinates with the project manager or the homeowner directly on timing. Painting too early on new plaster causes problems: Your decorator would rather delay a start than produce a finish that fails.
Plaster Repair and Preparation
Older plasterboard in rooms being redecorated often has visible joints, old screw holes, and areas where tape has lifted or joints have cracked. These should be assessed and repaired as needed before a finish coat is applied.
Your decorator fills, sands, and feathers all repair areas. Spot primer is applied to filled patches. Where original joints were not properly taped, your decorator re-tapes them, applies joint compound, and sands the repair flush.
For full interior painting across your home, your decorator can handle walls, ceilings, and woodwork throughout the Richmond borough.
Plasterboard Painting Costs in London
Your decorator assesses the requested plasterboard painting work before providing a written quotation.
Surface Area
A single kitchen extension in a Twickenham terrace costs less than a full loft conversion with multiple rooms, sloped ceilings, and dormer windows. Surface area is the primary cost driver.
Preparation Requirement
New plasterboard needs a sealing coat before finish coats: This adds time and cost compared to repainting an existing room. Joints and scrim that are not skim-coated add a further preparation stage.
First and Second Fix Staging
Single-stage or two-visit staging sets the scope; your decorator prices the agreed programme in a written quotation.


For full interior painting across the whole house, costs increase proportionally. Richmond Decorators also covers ceiling painting and wall painting across the borough.

Here’s How It Works
1. Assessment and Timing
Your decorator visits and confirms the plaster is ready to paint. Fresh plaster should be assessed as dry enough for the proposed coating before work begins. The programme once drying is complete is confirmed.
2. Repair and Preparation
Joints, screw holes, and any surface damage are filled, sanded flush, and spot-primed. Lifted tape or open joints are re-taped and compounded where needed.
3. Sealing Coat
Your decorator selects a sealing or primer coat for the assessed new plaster and proposed finish system. Your decorator allows full dry time before proceeding. The preparation step depends on the plaster condition and the coating manufacturer guidance.
4. First Finish Coat
Full-strength emulsion is applied. The first coat confirms surface consistency. Any remaining absorption differences are addressed before the second coat.
5. Second Coat and Inspection
The second coat completes the finish. Your decorator inspects all surfaces in good light, checking for any missed areas or uneven coverage before leaving.
