Find the right plasterer

Plasterers are the essential craftsmen responsible for creating the smooth, flat surfaces required for a high-quality decorative finish. Whether you are renovating a period property, finishing a new extension, or simply refreshing a tired room, a professional plasterer provides the "canvas" for your paint or wallpaper.

In the UK, plastering work ranges from internal skimming and dry lining to heavy-duty external rendering and the removal of dated Artex ceilings. Their work is not just about aesthetics; it also provides vital fire protection, soundproofing, and thermal insulation for your home.

Hiring a skilled plasterer ensures that your walls are perfectly plumb and your corners are sharp. Attempting to hide poor plasterwork with thick paint rarely works, making this one of the most important stages in any home improvement project.

What to Expect When Hiring a Plasterer

A professional plasterer offers a variety of services to suit different wall types and project requirements. Here is what you can typically expect:

• Skimming: Applying a thin, final coat of plaster over existing walls or new plasterboard to create a smooth, glass-like finish.
• Dry Lining: Fixing plasterboard to timber or metal frames (or "dot and dab" to masonry) before skimming.
• Rendering: Applying sand and cement or modern acrylic/silicone mixes to exterior walls for weatherproofing and aesthetics.
• Artex Removal/Covering: Safely flattening dated textured ceilings, either by over-boarding or scraping and skimming.
• Screeding: Laying a smooth layer of concrete or specialized floor screed to prepare for final flooring.
• Coving and Mouldings: Installing decorative cornices or repairing traditional lime plaster features in heritage homes.

The process usually begins with a site visit to assess the condition of the "substrate" (the wall underneath). Once the job starts, the plasterer will protect your floors with heavy-duty plastic or dust sheets, prepare the surface with a bonding agent like PVA or Blue Grit, and apply the plaster in stages before a final "trowel up" as it sets.

Why Hire a Professional?

Plastering is widely regarded as one of the most difficult DIY tasks to master. It is a physically demanding trade that requires perfect timing; if you move too slowly, the plaster "sets" on the wall, leaving you with lumps and ridges that are impossible to sand out later.

Skill and Finish: A professional has the muscle memory to apply consistent pressure across a whole wall. They can achieve a finish that is perfectly flat and ready for paint without the need for endless sanding.

Health and Safety: Older UK homes often have Artex ceilings that contain white asbestos. A professional plasterer will know how to identify this risk and either board over it safely or arrange for a specialist test before disturbing the surface.

Specialist Knowledge: For older properties (pre-1919), using modern gypsum plaster can trap moisture and cause damp. A professional can advise on traditional lime plastering, which allows the building to "breathe," protecting the structural integrity of your home.

Typical Costs

Plastering costs in the UK are influenced by the size of the room, the height of the ceilings, and the condition of the existing walls. Prices typically include materials (beads, scrim tape, and plaster) and labour.

Service	Low £	High £	Notes
Skimming a Small Room	£450	£700	Assumes walls are in good condition.
Full Room (Boarding & Skimming)	£800	£1,400	Medium-sized bedroom, including ceiling.
Artex Removal (Over-boarding)	£400	£650	Per average-sized ceiling.
Patching/Repair Work	£150	£300	Small repairs or "chased" electrical wires.
External Rendering (per m²)	£50	£90	Depends on material (Cement vs Monocouche).

Factors that can increase the price include the need for scaffolding, the removal of old "blown" plaster, and whether the room is currently occupied with furniture that needs moving or extra protection.

How to Choose the Right Plasterer

Finding a reliable plasterer requires checking both their technical skills and their reputation for cleanliness. Here is what to look for:

• Check Qualifications: Look for NVQ Levels 2 or 3 in Plastering or City & Guilds certifications.
• View Recent Work: Ask for photos of "unpainted" plaster. A good finish should look slightly polished and consistent in colour.
• Accreditations: Check if they are members of the British Gypsum Certified Plasterer Scheme or the Federation of Master Builders (FMB).
• Cleanliness: Plastering is a wet, messy trade. A good pro will mention how they plan to protect your carpets and woodwork.

Questions to ask before hiring:

• Do your prices include the cost of all materials and waste disposal?
• How long will the plaster need to dry before I can paint it?
• Will you be using "beads" on all external corners to ensure they are straight and impact-resistant?
• Do you have public liability insurance?

Frequently Asked Questions

How long does new plaster take to dry?

In a well-ventilated room, new plaster typically takes 3 to 5 days to dry completely. It will turn from a dark "chocolate" brown to a uniform light pink. Do not use high heat to speed this up, as it can cause the plaster to crack.

Do I need to prime new plaster before painting?

Yes. New plaster is highly absorbent. You must apply a "mist coat" (a watered-down emulsion) first. If you apply thick paint directly, it will not bond properly and may peel off in sheets later.

Can you plaster over old wallpaper?

No. Plastering over wallpaper is a recipe for failure. The moisture in the plaster will loosen the wallpaper glue, causing the new plaster to sag, crack, or fall off the wall entirely. All paper must be stripped first.

What is "blown" plaster?

Blown plaster occurs when the plaster has pulled away from the wall behind it, usually due to damp or age. You can identify it by a hollow sound when you tap the wall. Blown sections must be removed and patched before skimming.
