Walk onto any building site or renovation project, and you'll hear terms like plastering, rendering, skimming, and dry lining used interchangeably—creating confusion that costs homeowners money. Hiring a dry liner when you need rendering, or expecting a plasterer to handle specialised work they don't perform, leads to delays, unsuitable finishes, and wasted expenditure.
This comprehensive guide clarifies exactly what plasterers, renderers, and dry liners actually do, explains the different plastering techniques and when each is appropriate, breaks down realistic 2025 costs, and helps you hire the right specialist for your specific project.
The Core Distinctions: Three Related But Different Trades
While these trades all involve creating finished wall and ceiling surfaces, they use different materials, techniques, and skills.
Plasterers: The Wet Plaster Specialists
What they do: Plasterers apply wet plaster (gypsum-based or lime-based) to internal walls and ceilings, creating smooth surfaces ready for decoration.
Types of plastering work:
- Skimming: Applying thin finishing coat (3-5mm) over existing plaster or plasterboard
- Full plastering: Multiple coats including base coat and finishing coat (5-30mm total thickness)
- Repair work: Patching damaged plaster, filling cracks, making good
- Ornamental work: Creating decorative mouldings, cornices, ceiling roses (specialist skill)
- Venetian/polished plaster: High-end decorative finishes (specialist)
Costs 2025:
- Hourly rate: £15-£30 (average £22-£25)
- Day rate: £200-£350 (average £250)
- Skimming per sqm: £15-£30 (average £24)
- Full plastering per sqm: £40-£60
Renderers: The External Wall Specialists
What they do: Renderers apply external wall coverings to protect brickwork/blockwork from weather while improving appearance.
Types of rendering:
- Cement render: Most common UK choice (£10-£35 per sqm)
- Lime render: Traditional, breathable, for older/listed buildings (£30-£60 per sqm)
- Monocouche render: Single-coat coloured render (£40-£70 per sqm)
- Silicone render: Modern, self-cleaning properties (£50-£80 per sqm)
- Insulated render: Includes insulation layer (£80-£150 per sqm)
Costs 2025:
- Day rate: £200-£350
- Average house rendering (complete): £1,900-£6,000+ depending on size
Note: Many plasterers also render, but not all. Rendering requires scaffolding, weather considerations, and different material knowledge.
Dry Liners: The Plasterboard Specialists
What they do: Dry liners install plasterboard (drywall) to walls and ceilings, creating surfaces ready for decoration with minimal wet trades.
Dry lining methods:
- Dot and dab: Plasterboard fixed to masonry walls with adhesive
- Stud walls: Plasterboard fixed to timber or metal frame
- Suspended ceilings: Plasterboard on ceiling framework
- Partition walls: Creating new room divisions
Advantages:
- Faster than wet plastering
- Less messy
- Can incorporate insulation
- Quicker drying (can decorate sooner)
Still requires:
- Taping joints between boards
- Filling screw holes
- Usually a thin skim coat for best finish
Costs 2025:
- Day rate: £200-£300
- Per sqm installed: £20-£40
- Full room dry lining: £540-£920
Understanding Plastering Techniques: When to Use Each
Different situations demand different approaches. Understanding these prevents costly mistakes.
Skimming: The Surface Refresh
What it is: Applying a thin (3-5mm) finishing coat of plaster over existing plaster or new plasterboard.
When appropriate:
- Existing plaster in reasonable condition but has minor imperfections
- New plasterboard installed (requires skimming for smooth finish)
- Painted walls that need refreshing (after removing loose paint)
- Walls with small cracks and blemishes
When NOT appropriate:
- Badly damaged or blown plaster (needs full replastering)
- Damp walls (address damp first)
- Uneven walls requiring significant levelling
- Bare brick/block (needs base coat first)
Process:
- Prepare surface (remove loose material, treat with PVA if needed)
- Apply thin coat of finishing plaster
- Trowel to smooth finish
- Allow to dry (2-3 days minimum before decorating)
Costs 2025:
- Small room (10-12 sqm): £430-£550
- Medium room (15-20 sqm): £550-£750
- Large room (25-30 sqm): £750-£1,000
Timeline: 1-2 days for average room.
Full Plastering: The Complete Solution
What it is: Multiple coat application including base coat (undercoat) and finishing coat, total thickness 5-30mm.
When necessary:
- Bare brick, block, or concrete walls
- Badly damaged existing plaster
- Blown plaster requiring removal
- Uneven walls needing levelling
- New extensions or conversions
Process:
- Prepare surface (clean, wet if too dry, apply bonding agent if needed)
- Apply base coat (bonding, browning, or render coat depending on surface)
- Scratch surface to provide key
- Allow base coat to dry
- Apply finishing coat
- Trowel to smooth finish
- Allow complete drying (up to 4 weeks for full cure)
Costs 2025:
- Small room: £600-£900
- Medium room: £800-£1,200
- Large room: £1,000-£1,500+
Timeline: 2-4 days for average room plus drying time.
Dry Lining: The Modern Alternative
What it is: Installing plasterboard instead of wet plaster, then finishing joints and usually applying thin skim coat.
When appropriate:
- New stud walls or partitions
- Uneven masonry walls (dot and dab method)
- When speed is priority
- Incorporating insulation
- Avoiding drying time
Limitations:
- Not suitable for very damp environments without treatment
- Can sound hollow
- Vulnerable to impact damage
- May need battens if walls very uneven
Cost comparison: Dry lining often similar or slightly cheaper than full plastering, but much faster—can decorate within days rather than weeks.
Costs 2025:
- Standard room dry lining: £540-£920
- Including skim coat: Add £300-£500
Types of Plaster: What They're Used For
Understanding plaster types helps you communicate with tradespeople and assess quotes.
Gypsum Plasters (Most Common)
Bonding plaster:
- Use: Base coat for low-suction surfaces (concrete, painted surfaces)

Common Plastering Problems and Solutions
Understanding typical issues helps you make informed decisions.
Blown Plaster
What it is: Plaster separated from wall, sounds hollow when tapped.
Causes: Damp, poor adhesion, age, structural movement.
Solution: Remove affected areas, address underlying cause (especially damp), replaster.
Cost: £100-£200 per square metre for removal and replastering.
Cracking
Types:
- Hairline cracks: Normal settlement, cosmetic
- Wider cracks: May indicate structural issues
Solutions:
- Minor cracks: Fill and decorate
- Significant cracking: Investigate cause, may need replastering
- Structural cracks: Require structural engineer assessment
Costs: Simple filling £70-£150, full replastering £600-£1,200+ per room.
Damp Issues
Critical: Never plaster over damp walls.
Must do first:
- Identify and eliminate damp source
- Allow walls to dry completely
- Treat with appropriate damp-proofing
- Consider tanking if necessary
Then: Use appropriate plasters (some are more breathable for damp-prone areas).
Hiring Plasterers: Essential Questions
Plastering quality dramatically affects final decoration. Choose carefully.
Skill and Experience Questions
"What types of plastering do you specialise in?"
- Clarify: Skimming, full plastering, rendering, dry lining, ornamental work
