Spray Plastering London
Spray plastering — also known as machine plastering — is a modern, efficient method of applying plaster to walls and ceilings using specialist spray equipment. It's faster, more consistent, and often more cost-effective than traditional hand-applied plastering, especially for large areas, new builds, and commercial projects.
How much does spray plastering cost in London?
Spray plastering in London costs £10–£18 per m² including labour and materials — comparable to hand skimming but 30–50% faster, making it more cost-effective for large areas. A typical 3-bed house costs £1,500–£3,500 spray plastered. It suits new builds, extensions and commercial jobs over 100m².

What Is Spray Plastering?
Spray plastering is a mechanised plastering method where plaster is mixed and pumped through a hose to a spray gun, which applies it to the wall or ceiling surface under pressure. A plasterer then flattens and smooths the sprayed plaster by hand using a trowel, producing a finish identical to traditional hand-applied plastering.
The key difference is the application method. Instead of manually loading a hawk board and trowelling plaster onto the wall — a physically demanding and time-consuming process — the machine does the heavy work. The plasterer focuses on finishing, which is where skill and experience matter most.
Spray plastering uses the same gypsum-based plaster materials as traditional plastering (such as Knauf MP75, British Gypsum ThistlePro, or similar products), so the finished result is identical in appearance, durability, and performance. The difference is purely in speed and consistency of application.

Cost vs Hand Plastering
Spray plastering costs are similar to hand plastering per m2, but the real saving is in time. A job that takes 5 days by hand may take 2–3 days by spray. For large jobs, this reduced labour time translates to lower total costs despite similar per-m2 rates.
Advantages of Spray Plastering
Faster Application
Machine application is 30–50% faster than hand trowelling. A spray plasterer can cover 60–80m2 per day vs 40–50m2 by hand. This means quicker project completion and less disruption.
Consistent Coverage
The machine applies plaster at a consistent rate and thickness, reducing the risk of thin spots, thick spots, and variation in finish quality. Every part of the wall receives the same amount of plaster.
Better Adhesion
Plaster is forced onto the wall under pressure, creating a stronger bond than hand application. This is especially beneficial on dense surfaces like concrete and blockwork where hand-applied plaster can sometimes fail to bond.
Less Waste
The machine mixes only what's needed and applies it directly to the wall, reducing waste from over-mixing or dropped plaster. Material waste is typically less than 5% vs 10–15% for hand plastering.
Ideal for Large Areas
Spray plastering comes into its own on large, flat surfaces. New builds, extensions, warehouses, and commercial spaces benefit most. The bigger the area, the greater the time and cost savings.
Same Quality Finish
The finished surface is identical to hand-applied plastering — smooth, flat, and ready for painting. The machine only applies the plaster; a skilled plasterer still finishes it by hand.
When to Choose Spray Plastering
Spray plastering isn't always the best choice. Here's when it makes sense — and when traditional hand plastering is better.
Best for: New builds, extensions, whole-house renovations, commercial fit-outs, and any project with over 100m2 of wall and ceiling area. The machine setup time is justified by the speed savings over large areas.
Best for: Properties with large, unobstructed wall areas — new plasterboard partitions, bare blockwork, or recently stripped walls. The spray gun works fastest on open surfaces without many corners, reveals, or obstacles.
Not ideal for: Small patch repairs, single rooms under 50m2, or properties with complex layouts (many small rooms, lots of corners). The machine setup and cleaning time makes it slower than hand plastering for small jobs.
Not ideal for: Period properties requiring lime plastering or specialist heritage finishes. Spray machines are designed for gypsum-based plasters, not traditional lime mixes.
Not ideal for: Detailed or decorative plastering — cornices, ceiling roses, or ornate features. These require hand application and specialist skills that machines can't replicate.
