Planning note: Building rules, product standards, taxes and professional requirements differ by location. Use this guide for preparation, then verify local requirements.
Identify the existing surface
A sound wall needing a thin skim is different from loose plaster, exposed masonry or a surface affected by damp. Describe the substrate accurately when seeking quotes and ask what preparation is included.
Cracks may be cosmetic, but repeated or widening cracks need investigation before being covered. Plaster is a finish, not a structural repair.
Separate preparation from finishing
Removal, boarding, bonding coats, beads, mesh, protection and waste can take longer than the visible final coat. Include ceilings, reveals, awkward corners and access height in the scope.
Moving furniture and protecting floors may be your responsibility unless the quote states otherwise.
Allow drying and decorating time
Drying depends on product, thickness, ventilation, temperature and humidity. Painting too early can trap moisture or damage the finish. Follow the plasterer's and product manufacturer's guidance.
Plan the wider programme so flooring, cabinets and final decoration do not begin before the surface is ready.
Address damp first
Covering active damp usually leads to staining, failure or mould returning. Find the source, repair it and allow the building fabric to dry before refinishing.
Seek experienced advice for exterior render, heritage materials, unknown substrates and significant movement.
