A practical set of site checks and questions for the plasterer, painter and homeowner before primer or finish coats are applied after a renovation.
New plaster can dry at different rates across the same room. Plaster type, thickness, repairs, background, temperature, ventilation and site moisture all matter. A date supplied at handover is useful context, but it is not a universal test of whether every area is ready.
Use the guide to painting after plastering and renovation for the wider order of trades, joinery and final decoration. This page focuses on the inspection immediately before the coating system is agreed.
The painter should know what material was applied, whether patching or skimming happened at different times and whether there are unresolved leaks or building defects. Product data sheets and the coating manufacturer’s instructions should guide surface preparation, primer selection and application conditions.
If an area looks or behaves differently, record it rather than covering it to keep a programme. The next step may be more drying, local repair, investigation or clarification from the plasterer, builder or coating supplier.
Look across walls and ceilings in useful light. Record darker patches, visibly different repairs, edges, beads, corners and areas around openings. Appearance alone is not a moisture measurement, but variation needs an explanation.
Check for loose material, powdering, cracking, ridges, trowel marks, damaged corners, exposed beads, contamination and repairs that remain proud or hollow. Agree which trade corrects each defect.
Confirm the building is weather-tight, leaks are resolved and ventilation and temperature can meet the chosen product instructions. Wet trades still operating nearby can change conditions after an inspection.
Identify the intended primer or first-coat system, finish product and application guidance. Do not treat a generic “mist coat” recipe as suitable for every plaster and paint system.
Record the room, wall or ceiling, material if known, installation or repair dates and any sections completed later. Ask the plasterer or builder to identify different substrates and patched areas.
Check roofs, windows, plumbing and known moisture sources are resolved, other wet work is considered and the room can be ventilated and maintained within the product conditions.
Review surfaces in consistent light and photograph exceptions. Where moisture testing is appropriate, use a method and interpretation suitable for the substrate rather than applying one universal reading.
List cracks, damaged edges, proud repairs, contamination and incomplete junctions. Agree whether the plasterer, carpenter, builder or painter is responsible before decoration starts.
Follow the selected manufacturer’s instructions for cleaning, de-nibbing, dust removal, primer or first coat, dilution if permitted, drying and recoating. Protect adjacent joinery and finished surfaces.
Inspect the prepared and primed surface before the full finish proceeds. Record unexpected suction, staining, defects or adhesion concerns and agree the response rather than hiding them under further coats.
Ask for the plaster or repair type, relevant product information, application dates and identification of areas completed in separate visits.
List leaks, damp investigation, cracked backgrounds, unfinished joinery, electrical work, sealants, access limitations and repairs assigned to another trade.
Confirm the primer or first coat and the finish product, together with surface preparation, dilution, coverage, application and recoat instructions from the manufacturer.
Name the person who confirms remedial work, the painter who accepts the decorating substrate and the contact who approves any change to scope or programme.
Send the plastering completion date, photographs of the rooms and details of the current heating and ventilation. We assess the surface and agree a coating system before confirming the start. Drying conditions and the selected product affect the programme, so a fixed number of days does not suit every property. The quotation should distinguish preparation, the first coat and the agreed finish coats.
No. A consistent pale appearance is useful to observe, but it is not a complete moisture assessment. Investigate darker or different areas and use an appropriate test where required.
No. The first-coat or primer specification depends on the substrate and chosen paint system. Follow the current product data and manufacturer guidance.
Responsibility should be agreed before decoration. Some minor preparation may sit in the painting scope; structural, plastering or carpentry defects may belong to another trade.
Send the location, room and surface list, photographs, plastering or repair information, joinery status, other-trade programme and preferred dates. Art Boys can confirm whether a site survey is needed before pricing.
