Room plastering costs by size

As a rough rule, plastering costs increase in line with the size of the room:

• Small room (around 9m²): from £1,100

• Large room (around 18m²): around £1,900

These prices assume standard access and reasonably sound existing walls. Unstable plaster, high ceilings, or awkward layouts can push costs higher.

Plastering costs by type of work

Different plastering methods come with different costs, timeframes, and finishes.

Wet plastering

A traditional method that produces a solid, durable finish but takes longer to apply and dry. On the plus side, this type of plastering is great for sound and damp proofing.

Dry plastering

Uses plasterboard fixed to walls, then skimmed over. This is quicker than wet plastering and allows insulation to be added.

Skim plastering

A finishing layer applied over existing plaster to repair any cracks or holes and create a smooth, paint-ready surface. It's less time consuming and can be more affordable than wet or dry plastering.

• Average skim plastering cost: £24 per m²

Rendering

The process of plastering the external walls of a house is called rendering. This process uses two or three coats of plaster to create an even finish and to protect external brickwork.

Specialist plaster finishes

• Venetian plaster: Also known as polished or marble plaster, Venetian plaster creates a smooth, high-gloss finish that resembles natural marble. It’s made from lime putty and marble dust and is commonly used for feature walls and ceilings.

• Tadelakt (Moroccan plaster): A traditional lime-based plaster, Tadelakt is naturally waterproof and highly durable. It’s often used in bathrooms, wet rooms, and contemporary interiors where a seamless, decorative finish is required.

Specialist plaster finishes require experienced plasterers and detailed preparation. Therefore, expect to pay higher rates than standard plastering, with prices varying depending on the finish, room size, and design complexity.

What are approximate plastering rates?

Plasterer day rates

Most plasterers charge either a daily rate or a fixed price.

• Average plasterer day rate: £300

Rates may be higher for complex work or in London and the South East.

Plastering rates per square metre

• Skim plastering: £24 per m²

• Specialist finishes: Polished finishes often start from £120/m², with textured or decorative finishes priced around £100/m², depending on the complexity and size of the project
