Skim over plasterboard, backing plaster onto brick or block, full replastering of older properties, lime plaster on solid-wall period stock — polished to a paint-ready finish. ### Who It's For Homeowners after a flawless paint-ready finish; renovators reskimming tired walls; landlords needing fast, durable plaster turnarounds; anyone tired of bumps, cracks and patches showing through every coat of paint. ### When You Need It Plaster goes on once first-fix electrics and plumbing are complete and walls are dry. New plasterboard takes a skim straight away; older walls need a primer or backing coat depending on substrate. ### Why It Matters Bad plaster shows up in raking light forever. The cost difference between a cheap skim and a properly-finished surface is small. The cost difference 10 years later — when you're still patching it — is huge. What Happens If You Wait ## The Cost OfDoing Nothing. Plaster is the most-seen surface in your house. When it's wrong, you see it every time the sun comes through the window. ### Risks Of Ignoring It - →Skim onto damp or dusty walls — blown plaster within months, full strip and reskim. - →Skim onto modern gypsum on solid stone — moisture trapped, plaster blows. - →Wrong mesh or bead at corners — cracking, edge damage, expensive repairs. - →No movement detailing at junctions — straight-line cracks across the ceiling. - →Skimming over wallpaper paste residue — adhesion fails, plaster comes off in sheets. ### Common Mistakes Customers Make - ×Letting a handyman 'have a go' at plastering. - ×Skimping on the prep before the first trowel touches the wall. - ×Skimming over old wallpaper or unsealed surfaces. - ×Painting before the plaster has fully dried out. Our Process ## First Call ToFinal Sign-Off. 01 ### Survey & Spec Check substrate condition, moisture content, existing finishes. Agree skim, backing coat or full replastering spec. 02 ### Fixed Quote Itemised quote by m² of wall or by room — you know exactly what's being plastered and to what spec. 03 ### Prep PVA or bonding primer where required, beads and stop-ends fixed, dust covers laid, openings masked. 04 ### Apply & Polish Backing plaster (where needed), then two-coat skim trowelled and polished to a paint-ready finish. 05 ### Inspect & Hand Over Walked under raking light, touch-ups same day. Plaster left to dry to a uniform colour before paint. Why It's Worth It ## What YouActually Get. ### Paint-Ready Finish Polished skim that takes the first coat of paint cleanly — no patching, no flashing under the roller. ### Flat Under Raking Light Walls and ceilings checked under low-angle light before sign-off. What looks flat at noon stays flat at sunset. ### Lime Plaster Where Needed Solid-wall period stock gets lime plaster and breathable build-ups, not modern gypsum that traps moisture. ### Clean Edges & Corners Beads, stop-ends and movement joints set properly so corners stay crisp and don't crack. ### Tidy Site, Every Day Floors covered, dust contained, debris bagged. You can still live in the rest of the house. In Detail ## Plastering —Every Variation Covered.

Paint-ready finish for the decorator. ### Re-Skim Of Tired Walls Over existing sound plaster after preparation — a faster, cheaper option than full replastering when the underlying surface is solid. ### Full Replastering Hack-off and complete replaster of failing surfaces — backing coat onto brick or block, then two-coat skim. The right route when the existing plaster has blown or wallpaper has stripped it. ### Lime Plaster For Period Stock Lime plaster over solid stone or brick walls in Victorian and Edwardian terraces — breathable, sympathetic to old building materials, the only correct spec for these walls. ### Repair & Patching Cracks, holes, blown patches and repair of damaged plaster after structural alterations or first fix. Feathered into surrounding plaster so the repair doesn't ghost through paint. Questions ## StraightAnswers. Cost, timeline, guarantees, lifespan, emergency availability — the questions everyone asks, answered before you call. Ask Yours ### How much does plastering cost in South Wales? +Cost depends on m² of wall, ceiling vs wall, skim vs full replaster, and prep needed. We quote per room or per m² in writing after a site visit. ### How long does plastering take to dry? +Fresh skim takes 2–7 days to dry to a uniform colour depending on temperature, ventilation and humidity. Don't paint until the plaster is one consistent shade — usually a pale buff. ### Can you skim over Artex? +Yes — either skim over with a bonding primer, or for textured Artex we recommend a backing coat first. Asbestos-suspect Artex needs testing before we touch it. ### Do you do lime plaster? +Yes — lime plaster is essential on solid-wall period properties to maintain breathability and avoid trapping damp. Different rhythm and skill than modern gypsum but bread-and-butter work for us. ### Will plaster cracking come back? +Cracks from poor prep or wrong mix will come back. Cracks from building movement need addressing at source — we'll diagnose the cause before quoting cosmetic repair. ### Do you cover ceilings as well as walls? +Yes — ceiling skim is a normal part of any room replaster. Bigger ceilings or vaulted spaces are quoted by area as standard. ### Can you plaster around first-fix electrics and plumbing? +Yes — coordinated with your electrician and plumber, or with our team if we're running the whole job. First fix has to be complete before we start. ### Do you tidy up after? +Yes — floors covered during work, dust contained as far as possible, all debris bagged and removed at the end. The site stays liveable around the work. Next Step ## Plaster That Doesn't Ghost Through Paint.
