Plastering vs Drylining: Which Is Right for You?

Two different methods for creating smooth walls. Here's how they compare and when to choose each one.

When you're renovating or building, you have two main options for internal wall finishes: traditional wet plastering or modern dry lining (also called drywalling). Each has advantages and works better in different situations.

What Is Traditional Wet Plastering?

Traditional plastering uses gypsum plaster mixed with water and applied to walls in layers. For most UK homes, this means a base coat (browning or bonding plaster) followed by a finishing skim coat. The plaster is troweled smooth by hand and left to dry for several days before you can decorate.

When it's used:

• Repairing or refreshing existing plaster walls
• Period properties where traditional methods are preferred
• Curved walls or complex shapes that are hard to board
• When you want the authentic feel of a traditional finish

What Is Dry Lining?

Dry lining involves fixing sheets of plasterboard (typically 2400mm × 1200mm × 12.5mm) to walls or frames, then either leaving them ready to decorate or applying a thin skim coat of plaster over the joints and surface. No wet base coat is used.

There are several dry lining methods:

• Dot-and-dab: Plasterboard stuck to existing walls with adhesive dabs
• Stud walls: Metal or timber frame with plasterboard on both sides
• Battened walls: Timber battens fixed to walls, then plasterboard screwed to the battens

Speed: Dry Lining Wins

Dry lining is significantly faster than wet plastering:

Dry lining: A bedroom can be boarded in a few hours. If you're leaving it unskim med (taped and filled joints only), you can decorate within 24 hours. If skimming over the boards, add 1-2 days for the skim to dry.

Wet plastering: A bedroom takes 1-2 days to plaster (depending on whether you need a base coat). Then you wait 3-7 days for it to dry before decorating.

If time is critical (a rental turnaround, for example), dry lining is the faster option.

Cost: Usually Similar

The cost difference is smaller than you might expect:

Dry lining: Materials (plasterboard, adhesive or studs, screws) cost more than plaster. Labour is faster, so you pay less for time. Overall: £25-35/m² typically.

Wet plastering: Materials are cheaper (bags of plaster), but labour is more skilled and takes longer. Overall: £15-25/m² for re-skimming, £25-35/m² for full replastering.

For large areas, dry lining often works out cheaper because it's so much faster. For small repairs or single walls, wet plastering can be more economical.

Durability: Both Are Long-Lasting

Both methods produce durable walls when done properly:

Wet plaster: Lasts decades if kept dry. Hard and impact-resistant once fully cured. More resistant to dents from furniture or knocks.

Plasterboard: Also lasts decades. Slightly more vulnerable to impact damage (can dent or punch through if hit hard), but easy to patch if damaged. Modern boards are moisture-resistant and fire-rated where needed.

Insulation and Soundproofing

Dry lining has a clear advantage here:

Thermal insulation: You can use insulated plasterboard (Kingspan, Celotex bonded to the board) when dry lining. This adds significant thermal insulation to external walls. Traditional plastering doesn't provide insulation.

Soundproofing: Stud walls can be filled with acoustic insulation (Rockwool or similar) and built with acoustic plasterboard. This significantly reduces sound transmission between rooms. Traditional solid plaster walls are actually better for sound insulation, but you can't improve an existing plaster wall easily.

When to Choose Wet Plastering

Traditional plastering is the better choice when:

• You're repairing or refreshing existing plaster walls (adding boards would reduce room size)
• The walls are curved, angled, or have complex shapes
• You're working on a period property and want an authentic finish
• You need a very hard, impact-resistant surface (commercial use, high-traffic areas)
• You're doing small repair work where boarding would be overkill

When to Choose Dry Lining

Dry lining makes more sense when:

• You're building new partition walls (stud walls are faster and lighter than blockwork)
• You need to add insulation to external walls
• Soundproofing between rooms is a priority
• You're on a tight timescale
• The existing walls are in very poor condition (boarding over them is quicker than stripping and replastering)
• You're converting a loft, garage, or outbuilding (where lightweight construction is preferred)

Can You Combine Both?

Yes, and it's common to do so. For example:

• Dot-and-dab plasterboard to walls, then skim over the boards for a traditional smooth finish
• Build a stud partition (dry lining), then skim it to match existing plastered walls
• Use dry lining on ceilings (faster and lighter than wet plaster) but traditional skim on walls

Combining methods gives you the speed and insulation benefits of dry lining with the smooth finish of traditional plastering.

Which Is Better for DIY?

Neither is easy for a first-timer, but if you're determined:

Dry lining: Physically hard work (plasterboard is heavy) but more forgiving. Mistakes can be fixed. You can learn to tape and fill joints with practice.

Wet plastering: Requires more skill. Plaster sets quickly, so you have a short working time. Getting a smooth finish takes practice. Mistakes are harder to fix once the plaster has set.

For DIY, dry lining with taped joints (no skim) is the more achievable option.
