Gypsum plaster is standard for interior walls and ceilings in most modern homes. Lime plaster is softer and lets old walls breathe, which matters in buildings with solid masonry. Cement-based plaster resists moisture and is used in bathrooms, basements, and exterior walls. Each type needs different mixing ratios, drying times, and primers before paint can go on.
A standard 2-coat system covers most fresh plasterboard. A 3-coat system is used on uneven brick or where a glass-like finish is needed. Each coat needs to dry before the next, so a 3-coat job takes longer than a 2-coat job. Ask how many coats are included in the price.
A proper quote breaks down surface area in square metres, number of coats, and prep work. Ask whether corner beads, mesh tape, and primer are included. Watch for vague lines like labour and materials. Reputable plasterers measure the walls themselves and write the m² on the quote so you can compare offers side by side fairly.
If the existing plaster is sound but rough, a 2 mm to 3 mm skim coat is often enough. Skimming is faster than full re-plastering and produces less waste. However, skimming fails if the old layer is loose. A quick tap test tells the plasterer which route the wall needs.
Plaster will fail if it goes over dust, grease, or loose paint. The wall has to be scraped, washed, and sometimes primed with a bonding agent. Old wallpaper paste must be fully stripped. On bare concrete or brick, a scratch coat is applied first and allowed to cure. Skipping prep is the most common cause of cracking within the first year.
Plastering creates fine white dust during sanding and wet splashes during application. Ask if the plasterer lays floor sheeting and masks doorways. Furniture should be moved out before work begins. Without protection, dust settles on nearby surfaces for days after the job ends and damages wooden floors.
Finish plaster dries about 1 to 2 mm per day under good airflow and room temperature. A full 10 mm skim coat usually needs 7 to 14 days before painting. Lime plaster can take up to 4 weeks. Forced drying with heaters causes shrinkage cracks. Keep windows open or run a dehumidifier for the first 48 hours after application.
Many plasterers set a minimum call-out fee for repairs under 2 m². The minimum covers travel, setup, and cleaning, not just the patch. Bigger patches cost less per square metre because the setup cost is spread wider. Ask about the minimum fee before booking a small repair.
Hairline cracks under 2 mm wide can be filled with flexible filler and sanded. Wider cracks, blown plaster that sounds hollow when tapped, and water stains usually mean the full coat has to come off. Patch repairs on old plaster rarely match perfectly, so expect to repaint the whole wall rather than spot-painting after a repair.
Standard plaster has little soundproofing value on its own. Adding a dense plaster layer or a multi-layer board system improves acoustic performance. Older walls with lath and lime plaster often block sound better than modern thin skim coats. Discuss acoustic needs before choosing the system.
