Plasterboard Painting Services
Freshly Plastered Wall Painting
New plasterboard requires specialist preparation before finish paint is applied. The surface is porous and absorbs finish paint unevenly, leaving a patchy appearance unless properly primed first.
We apply sealing coats and primer to ensure even absorption and consistent finish coverage. See our interior painting page for more guidance on wall finishing systems.
Sealing Coat Application
A diluted sealing coat is applied to fresh plaster before finish emulsion. The sealing coat seals the surface and allows finish paint to apply evenly.
Without a sealing coat, finish paint on plasterboard leaves flat, uneven coverage that looks poor and feels unfinished.
First and Second Fix Coordination
Extensions and new build properties have first fix and second fix painting stages. First fix happens before plasterboard installation. Second fix happens after plasterboard is complete.
We coordinate these phases with construction timelines to ensure painting schedules align with drying times and construction progress.
New Build Extension Painting
Extensions with newly plastered walls receive complete preparation and finish painting. We apply appropriate primer systems to new plaster and coordinate with other trades.
Phased access is often required to work around construction activities.
Plaster Repair and Surface Preparation
New plasterboard sometimes arrives with minor damage or cracks. We assess conditions and include appropriate repairs in the quotation.
Small repairs are made as part of the preparation phase. Significant damage is addressed before primer application.


Here’s How It Works
1. New Plaster Assessment
We assess newly plastered surfaces, note any cracks or damage, and plan the painting schedule to align with drying times.
2. Crack Filling and Repairs
Small cracks and imperfections are filled with joint filler or plaster repair compound. Surfaces are sanded smooth.
3. Sealing Coat Application
A sealing coat is applied to the new plaster surface. This controls suction and ensures finish paint applies evenly.
4. Primer Application
Primer appropriate for plasterboard is applied after the sealing coat is dry. This provides a sound base for finish paint.
5. Finish Paint Application
Two finish coats of paint are applied. The finish coat is fully dried before handing over the newly painted surfaces.

Plasterboard Painting Costs in Surrey
Prices below are estimates only. Every project is different. Call 01483 930151 for a precise quote.


Plaster Condition
Smooth, well-finished plaster costs less to prepare than plaster with cracks or damage. Significant damage adds repair cost.
Post-war semis in West Molesey with extensions often have plasterboard partitions alongside original solid walls, each requiring a different primer system.
Room Size
Larger rooms cost more than smaller spaces. Wall area is the primary cost driver.
Typical ranges: small room newly plastered £200 to £350; standard bedroom post-extension £350 to £550; large room or new extension plasterboard £450 to £750.
Primer System
Standard primers are more economical than specialist systems. High-humidity areas such as bathrooms may require specialist moisture-resistant primers.
We advise on the correct primer system during the site visit. Plasterboard painting typically costs between £200 and £450 per room.
