Plastering is one of the most visible trades in any home renovation. A well-plastered wall or ceiling sets the foundation for a quality paint finish; a poor one — full of trowel marks, hollows or cracks — undermines everything that follows. Understanding what type of plastering your project needs, what it realistically costs and whether it is a job for a professional or an ambitious DIYer is the starting point for any project involving plasterwork.
Types of Plastering Work
The word “plastering” covers several distinct operations, each with different materials, skill requirements and costs.
Skim coat (finish plaster): A thin layer — typically 2–3 mm — of finishing plaster applied over plasterboard, existing plaster or a base coat. This is the most common plastering job in UK homes; it smooths out the surface to receive paint or wallpaper. Skill-intensive: the trowel work must be completed while the plaster is setting, and timing is critical.
Backing coat / base coat (browning): A thicker layer (8–12 mm) of sand-and-cement or bonding plaster applied to bare masonry or blockwork before the skim coat. Required on new extensions, knocked-out walls and anywhere bare brick or block is exposed.
Dot and dab plasterboard: Sheets of plasterboard bonded directly to the masonry using dabs of adhesive. No wet plaster — the board joints and screw holes are then filled and the surface skimmed or taped. Common in modern construction.
Rendering: External plasterwork applied to the outside of a building. Usually a two-coat sand-and-cement render or a proprietary through-coloured or silicone render system. Outside the scope of internal plastering.
Artex and textured finish removal: Many UK homes built between the 1960s and 1990s have textured ceilings. Removing these (or overboarding and skimming) is a common preparatory job. Pre-1985 textured coatings may contain white asbestos — test before disturbing.
Plastering Costs (2026)
| Job Type | Cost per m² | Typical Room Cost |
|---|---|---|
| Skim coat (over plasterboard) | £8–£15/m² | £250–£550 |
| Skim coat (over existing plaster) | £10–£18/m² | £300–£650 |
| Two-coat plaster (base + skim) | £15–£25/m² | £500–£1,000 |
| Single room replaster (25–30 m²) | — | £500–£1,000 |
| Full house replaster (4 bed semi) | — | £3,500–£7,000 |
| Ceiling skim only (15 m²) | £150–£350 | — |
| Patch repair (small crack or hole) | £80–£200 | — |
| Artex ceiling removal + skim | £18–£30/m² | £350–£600 |
Plasterer Day Rates (2026)
| Location | Day Rate |
|---|---|
| London | £300–£450/day |
| South East | £280–£400/day |
| Midlands | £250–£350/day |
| North England | £220–£320/day |
| Scotland/Wales | £200–£300/day |
Most plasterers prefer to quote by the job rather than per day or per m², because productivity varies significantly with room shape, access and the number of openings. A clear breakdown by room is the most useful basis for comparison.
Types of Plaster and When to Use Them
| Product | Use | Setting Time |
|---|---|---|
| Thistle MultiFinish | Skim over most backgrounds | 90–120 min |
| Thistle Board Finish | Skim over plasterboard | 90–120 min |
| Thistle Bonding Coat | Base coat on low-suction surfaces | 2–3 hrs |
| Thistle Browning | Base coat on brick/blockwork | 2–3 hrs |
| Thistle Hardwall | High-impact base coat | 2–3 hrs |
| Renovating plaster | Damp-resistant; old buildings | 2–3 hrs |
Thistle (part of Saint-Gobain) products dominate the UK market. A 25 kg bag of finishing plaster costs approximately £12–£18 at trade and covers roughly 5–7 m² at 2–3 mm thickness. A standard room skim uses 4–6 bags.
Preparing for Plastering
Good preparation makes the difference between plaster that bonds properly and work that cracks or falls away within months.
PVA bonding agent: Applied to the surface before plastering to reduce suction and help the plaster key in. Diluted approximately 3:1 (water:PVA) for most surfaces; undiluted for very porous masonry. Allow to dry to a tacky state before applying plaster.
Surface preparation:
- Remove loose or hollow plaster (tap and listen — a hollow sound indicates detached areas)
- Rake out cracks and fill large voids with bonding coat before skimming
- Remove wallpaper completely — any remaining backing absorbs moisture unevenly and causes blisters
- Treat any mould or damp before plastering (plastering over active damp is a waste of money)
Room preparation:
- Remove or sheet-cover all furniture
- Turn off and tape over electrical sockets and switches
- Lay dust sheets on floors — plaster droppings stain carpet and are hard to remove once cured
Can You Plaster Yourself?
Skim plastering is genuinely difficult to do well. It requires learning to read the set — understanding when the plaster is at the right stage for each pass of the trowel — and to apply even pressure across large areas. Most first attempts produce visible trowel marks, pulling, and unevenness that require heavy sanding to flatten.
DIY is reasonable for: Small patch repairs, gap filling, and touch-ups to existing plaster. A pre-mixed repair product such as Polyfilla or Gyproc EasiFill is more forgiving than bagged finishing plaster for small areas.
DIY is challenging for: Full room skims, large area base coats, and ceilings (the most physically demanding and technically unforgiving surfaces). Mistakes in a full room are expensive to fix after the plaster sets.
If you want to learn, a one or two-day plastering course (£150–£300 at most trade colleges) covers the fundamentals. Practising on a spare room or utility space before tackling main rooms is strongly recommended.
Hiring a Plasterer
Ask for recommendations from local builders or use review platforms such as Checkatrade or TrustATrader. Key questions to ask:
- Do they work alone or with a labourer? (A labourer mixing and loading speeds up a job significantly, but adds cost)
- Can they provide references from previous work — ideally in a similar property type?
- Will they supply materials or will you source them?
- What do they include in the prep — are they clearing the room, hacking off old plaster, or only applying new product?

Summary
Plastering is a skilled trade that significantly affects the quality of every subsequent finish in a room. In 2026, expect to pay £500–£1,000 to replaster an average room, or £3,500–£7,000 for a full four-bedroom house. For small repairs and filling, DIY is practical. For skim work across full walls and ceilings, the investment in a skilled plasterer will show — and save you — in the finished result.
