Plastering vs Drywall: Which Is Better?

Neither is universally better. Wet plastering gives a harder, more seamless finish suited to solid masonry walls and older UK homes; drywall (plasterboard) is faster, lighter and better suited to stud walls, partitions and modern construction. The right choice depends on the wall type, the finish you want, and whether you value speed or a traditional seamless surface.

The difference

In UK terms, "drywall" means a plasterboard wall finished by taping and jointing the seams, without a wet plaster coat. "Plastering" means applying wet plaster — a backing coat and a skim — to create a seamless surface. (A skimmed plasterboard wall is a hybrid: board for the flat surface, wet plaster for the finish.)

Comparison

| | Wet plastering | Drywall (taped board) | |---|---|---| | Finish | Seamless, hard, smooth | Flat, slightly textured at joints | | Durability | High — hard surface resists knocks | Moderate — boards dent more easily | | Installation speed | Slower (wet coats must dry) | Faster (dry fix) | | Cost | Higher labour | Lower labour | | Sound insulation | Dense, good mass | Good with the right board | | Repairs | Patched with plaster | Section replacement | | Best for | Solid masonry, older homes | Stud walls, partitions, new builds |

Finish and durability

A wet-plastered wall is a single hard, continuous surface. There are no joints to show through paint over time, and the dense surface takes knocks well. A drywall finish is flat but the joints, however well taped, can sometimes be visible under certain lighting, and the boards themselves are softer than a solid plaster coat.

Speed and cost

Drywall is faster to install because there's no wet coat to dry — boards are fixed and joints filled in a day or two. Wet plastering needs a backing coat to dry before the skim, which adds days. That speed is why drywall dominates new-build and commercial work. The trade-off is labour cost: wet plastering costs more because it takes longer and needs more skill.

Sound and thermal performance

Both can perform well. Wet plaster adds mass, which helps sound insulation. Drywall can incorporate insulation between the studs and use acoustic boards, which can match or exceed solid plaster for sound. For older solid walls, wet plaster suits the construction; for timber-frame, drywall is standard.

Repairs

A damaged plaster wall can be patched with new plaster and blended in. A damaged drywall panel often means cutting out and replacing a section of board, then re-finishing the joints. Small dents in drywall are easy to fill; larger damage is more disruptive.

Which suits UK homes?

• Older, solid-wall properties (Victorian, Edwardian, pre-1920s) — wet plastering matches the original construction and breathability. See our lime plastering guide for period properties.
• Modern cavity-wall and new-build homes — drywall or skimmed plasterboard is standard and practical
• Stud partitions and extensions — drywall, usually skimmed for the best finish

Many UK homes use a hybrid: plasterboard fixed to the wall (dry lining), then skimmed with wet plaster for a seamless finish. That combines the speed of boarding with the quality of a skim — see our dry lining vs plastering article.

FAQ

Is plastering better than drywall? Not universally. Plastering gives a harder, seamless finish for solid walls; drywall is faster and lighter for stud walls and new builds.

Is drywall the same as plasterboard? Essentially yes — "drywall" is the North American term for what the UK calls plasterboard or dry lining.

Which is more expensive? Wet plastering usually costs more in labour because it takes longer. Drywall is faster and cheaper to install.

Can you skim over drywall? Yes — skimming over plasterboard gives a seamless finish that combines the speed of boarding with the quality of wet plaster.

Which is better for older UK homes? Wet plastering, because it suits solid masonry walls and matches the original breathability.
