What to look for in a plasterer
- CSCS card — The Construction Skills Certification Scheme card proves a plasterer has passed a health-and-safety test and holds a recognised construction qualification. While not legally required for all domestic work, a reputable plasterer will carry one. It is a basic indicator of competence.
- PDA (Plasterers Decorators Association) membership — PDA members are vetted and follow a code of practice. Membership demonstrates commitment to professional standards and ongoing training in modern plastering techniques.
- Understanding of wet plastering vs dry lining — These are fundamentally different skills. Wet plastering (applying sand-and-cement render or multi-finish skim) requires years of practice. Dry lining (fixing plasterboard and skimming) is faster but less suitable for some applications. A good plasterer will advise which method suits your walls and budget.
- Knowledge of drying times and coats — Plastering requires patience. A two-coat system (scratch coat plus skim finish) is standard for most walls. Each coat needs adequate drying time — rushing leads to cracking and poor adhesion. Ask how many coats they plan and what drying times they allow between them.
- Supplies their own materials — A professional plasterer will supply their own plaster, PVA, bonding agent, beading, and scrim tape. If they ask you to buy materials, they may be inexperienced or trying to reduce their costs at the expense of quality.
- Public liability insurance — Plastering involves wet materials, heavy bags, and work at height on ceilings. Ensure cover of at least £1 million for domestic work.
Questions to ask before hiring
- Will this be wet plastering or dry lining, and why? The right method depends on the wall condition, room use, and budget. Wet plastering is traditional and gives a harder finish. Dry lining is faster and can incorporate insulation. The plasterer should explain their recommendation clearly.
- How many coats will you apply? A proper wet plaster job typically requires two coats: a base coat (bonding or browning) and a finish coat (multi-finish skim). If they plan only one coat on bare brick or block, the result will likely crack.
- What bonding agent or PVA will you use? Proper surface preparation is essential. The plasterer should use PVA (polyvinyl acetate) or a specialist bonding agent like SBR on the substrate before plastering. Skipping this step means the plaster may not adhere properly and could blow (delaminate) over time.
- How long should I wait before painting? New plaster needs time to dry fully — typically 4–6 weeks depending on thickness, ventilation, and season. A good plasterer will advise against painting too soon and recommend a mist coat of diluted emulsion as the first coat.
- Can you show me examples of recent plastering work? Look for smooth, flat surfaces, clean edges at corners and around door frames, and neat beading. Imperfections are easy to hide in photos — ask if you can visit a recently completed job in person.
Red flags to watch for
- Skimps on PVA or bonding agent. Applying plaster without proper bonding preparation is the most common shortcut. It saves a plasterer 30 minutes but leads to plaster blowing off the wall within months. If you see them skip this step, raise it immediately.
- Rushes drying times. Applying a second coat before the first has set properly causes cracking and delamination. A plasterer who promises to skim an entire house in a single day is almost certainly not allowing adequate drying time between coats.
- Cannot explain the difference between bonding and multi-finish. These are basic plastering materials. Bonding is the base coat; multi-finish is the skim finish. If a plasterer does not know the difference or uses the wrong product, their knowledge is inadequate.
- Leaves excessive mess without protection. Professional plasterers lay dust sheets, mask door frames, and protect floors. Plastering is inherently messy, but a professional minimises the impact. If they make no effort to protect your home, they lack professionalism.
- Quotes significantly below others without explanation. Cheap plastering quotes usually mean fewer coats, no bonding agent, or rushed work. If one quote is 40% below the others, ask exactly what is included and what is being left out.
