Service Overview
Plastering —
The Brief, In Plain English.
What It Is
Domestic plastering — multi-finish skim over existing plaster, full replastering to brick or block, plasterboard dot-and-dab or screw-fix, taping and jointing on stud-and-plasterboard, ceiling re-skims, lath-and-plaster repair on Victorian and Edwardian properties, external rendering (sand-and-cement, monocouche, K-Rend), and traditional pebbledash repair.
Who It's For
Homeowners across the Northwest with tired, cracked or bumpy walls and ceilings that need bringing back to a flat decorator-ready finish. Equally suitable for landlords refurbing buy-to-lets and for any extension, loft conversion or kitchen-refit project that needs plaster as the final preparation before paint.
When You Need It
Plastering programmes around drying times and humidity. Best results spring through autumn; winter plastering needs heating on in the property to drive moisture out. Book the survey as soon as you know the scope — most plastering jobs run inside 2–3 weeks of survey.
Why It Matters
Plaster is the final wall and ceiling surface before paint. Every defect — every bump, every trowel mark, every patched-in repair line — shows under modern matt emulsion paint and raking natural light. A flat, polished, properly closed skim is the difference between a room that looks finished and a room that looks 'done'.
What Happens If You Wait
The Cost Of
Doing Nothing.
Most plastering problems we get called to put right come from rushed work — second coat applied too thick, troweling-off too soon, not enough wet time to close the surface. The result is visible trowel marks, lippage at sheet joints, and a final finish that fights every coat of paint.
Risks Of Ignoring It
- →Skim applied over loose, blown or contaminated existing plaster — new skim debonds and comes off in sheets within months.
- →Plasterboard dot-and-dabbed without proper adhesive coverage — drum-hollow walls, ghosting visible under paint.
- →Ceilings skimmed without crack-bridging mesh — original crack telegraphs back through within 12 months.
- →External render applied to green blockwork or in freezing conditions — crazing, hairline cracking, eventual delamination.
- →Lath-and-plaster ceilings filled and skimmed without addressing failed nibs — sagging and crashing-down inside 5 years.
Common Mistakes Customers Make
- ×Skim-coating cracked or hollow plaster instead of stripping it — saves a day, costs a year.
- ×Buying plaster in a heatwave and applying it without retarder — it kicks off too fast and won't trowel out properly.
- ×Letting decorators paint freshly skimmed walls without misting coat first — paint peels off in sheets.
- ×Skipping the PVA bond coat on dense substrates — skim suction is wrong, surface won't close, finish is poor.
- ×Treating ceilings as the easy bit — they're the hardest surface in any room to skim well, and the most visible under daylight.

Plaster & Hand-Over
Plaster applied in correct coats, trowel-closed at correct wet time, dust-controlled, site cleared. Ready for decorators inside 7–14 days drying.
Why It's Worth It
What You
Actually Get.
Polished Trowel-Closed Finish
Final pass timed to the wet edge. Surface closes flat, glass-smooth, takes paint cleanly with no trowel marks visible under daylight.
Right Coat For The Substrate
Bonding coat over dense substrates, browning over masonry, hardwall over solid walls — the right base coat for the situation, not a one-size approach.
Beads, Stops & Reinforcement
Galvanised angle beads on all external corners, stop beads at exposed edges, scrim or mesh tape at every sheet joint. Cracks bridged, edges crisp.
Lath-And-Plaster Repair
Victorian and Edwardian lath-and-plaster ceilings repaired with proper screw-and-washer bracing rather than stripped out — preserves the period character.
Dust Controlled
Floor covered, doorways sheeted, vacuum cleaner running. Plaster dust contained to the room being worked in.
Decorator-Ready Finish
Walls left misting-coat-ready. Drying times advised in writing. Your decorator gets a surface that paints up first time.
In Detail
Plastering.
Materials, methods and the situations each variation applies to — so you know what you're buying before you buy it.
Skim Finish Over Existing Plaster
The most common plastering job — sound existing plaster brought back to a flat decorator-ready finish with a 2–3mm multi-finish skim coat. Substrate checked for soundness (hollow areas marked and cut out), PVA bond coat applied at correct dilution, two coats of multi-finish plaster, troweled in at the correct wet time. Typical room runs 1–2 days plus drying time. Ready for misting coat within 7–10 days.
Full Replastering To Brick & Block
Where existing plaster is blown, cracked or end-of-life, we strip to substrate, hack-key the masonry, apply scratch coat (sand-and-cement render for solid wall, bonding for blockwork or dense substrate), and finish in 2-coat multi-finish skim. Full replastering of a standard room runs 2–4 days plus drying time; reduces with experience and the number of plasterers on site.
Plasterboard Dot-And-Dab & Tape-And-Joint
Plasterboard fixed to masonry with adhesive dot-and-dab or to stud frame with drywall screws. Dot-and-dab adhesive applied in full perimeter dabs plus minimum 80% surface coverage — eliminates drum-hollow areas and ghosting. Tape-and-joint finish (without plaster skim) is the modern alternative on stud-and-plasterboard: scrim tape bedded in jointing compound, three coats sanded flat between, ready for paint without a skim coat.
Ceiling Re-Skims & Lath Repair
Ceilings are the hardest surface to skim flat — raking light shows every imperfection. We screw a 9.5mm or 12.5mm plasterboard overskim onto existing solid plaster ceilings (with adhesive backup), scrim every joint, then skim 2-coat to glass-smooth. For Victorian lath-and-plaster ceilings we screw-and-washer brace failed laths from above before re-skimming — preserves the period plaster cornice and roses.
External Render & Pebbledash
Sand-and-cement scratch-coat render (4:1 build-up coat, 3:1 finish coat) on traditional substrates; monocouche through-coloured render (Krend, Weber, Sto) on extensions and new build. Beads and stops at all external corners and openings; movement joints at 6m maximum centres on large elevations. Pebbledash repair and matching available on Lancashire mill-town properties where the period detail is integral to the elevation.

Cost, timeline, guarantees, availability — the questions everyone asks, answered before you call.
Ask Yours
How much does plastering cost in Liverpool?
+
Skim over existing plaster typically £18–£28 per m² (walls), £22–£32 per m² (ceilings). Full replastering to substrate £35–£50 per m². Standard 4m x 4m bedroom re-skim £350–£550 inclusive of walls and ceiling. Plasterboard dot-and-dab £35–£45 per m² supplied and fitted. Itemised written quote per project.
How long does plastering take?
+
A standard re-skim of a 4m x 4m bedroom (walls + ceiling) runs 1–2 working days plus 7–10 days drying time. Full replastering of the same room runs 2–4 days plus drying. Whole-house re-skim typically 1.5–3 weeks on site.
When can I paint freshly plastered walls?
+
Wait minimum 7 days for skim coats, 14–21 days for full replastering, longer in cold or damp conditions. First coat must be a misting coat (1 part emulsion to 4 parts water) to seal the plaster — full-strength emulsion on raw plaster peels off in sheets.
Can you skim over woodchip or anaglypta wallpaper?
+
No — and don't let anyone tell you otherwise. Plaster won't bond properly to wallpaper paste or textured paper, and the finish telegraphs every imperfection. We strip wallpaper as a separate line item before plastering, or quote the strip-out included in the plastering price.
Can you skim over Artex?
+
Yes, if it's pre-2000 we test for asbestos first (Artex containing chrysotile asbestos was widely used in the UK until late 1980s). Asbestos-free Artex gets screwed-on plasterboard overskim then 2-coat multi-finish skim. Asbestos-containing Artex requires licensed removal as a separate scope — we'll advise at survey.
What guarantee do you offer on plastering?
+
Workmanship guaranteed for 5 years on internal plastering, 10 years on external rendering. Material manufacturer warranties run separately. RG Loft Conversions & Extensions Ltd is fully insured — Company No. 11786422.
Do you do external rendering?
+
Yes — traditional sand-and-cement scratch-coat render, modern monocouche through-coloured render (Krend, Weber, Sto), and pebbledash repair on period Lancashire properties. External render typically £45–£75 per m² depending on system and substrate.
Do you cover my area?
+
Liverpool, Ormskirk, Southport, Formby, Skelmersdale and surrounding Northwest England on a sensible travel radius from our Huyton base.
