How to post a plastering or rendering job
Plastering and rendering quotes depend heavily on preparation. A wall that only needs a skim is different from loose plaster, damaged board, cracked backgrounds or a damp surface. External render also depends on substrate, exposure, access, detailing and the condition of the existing finish.
The most useful request gives approximate areas and shows the entire surface as well as each defect. Avoid specifying a finish system before the underlying condition has been assessed unless a designer or product specification already exists.
Measure the areas and identify the surfaces
- List each wall, ceiling, room or exterior elevation.
- Give approximate length, height and openings, or total area if known.
- Identify blockwork, concrete, plasterboard, old plaster or existing render where possible.
- State whether surfaces are painted, papered, tiled or newly constructed.
- Photograph junctions around windows, doors, sockets, beams and roof edges.
Describe cracks, movement and moisture
Explain where cracks occur, their approximate width and whether they are changing. Mention hollow or loose areas, staining, leaks, salt deposits and previous repairs. Plaster should not be used to conceal an unresolved leak or structural movement, so ask what investigation or repair must happen before finishing.
Define preparation and protection
- Removal of wallpaper, loose plaster, failed render or damaged board.
- Cleaning, bonding, beads, mesh, repairs and background preparation.
- Protection of floors, windows, kitchens, furniture and landscaping.
- Scaffolding, towers, waste removal and washing facilities.
- Drying conditions and when decorating or other trades can follow.
Describe the required finish
For interiors, state whether the goal is a paint-ready skim, patch repair, new board and skim, or a traditional finish. For exteriors, describe the desired texture and colour and ask respondents to name the proposed system, number of coats, detailing, preparation and manufacturer requirements.
Compare scope, access and exclusions
Request written quotes that separate preparation, materials, access equipment, application, protection and cleanup. CCPC recommends comparing several quotations and agreeing a contract covering scope, timing, payment and other important details. Confirm who makes good sockets, trims, joinery and decorations after the plastering work.[1]
Copyable plastering job description
Example: 'Prepare and skim the walls and ceiling of a 4.2 m by 3.6 m bedroom in Wexford. Wallpaper has been removed; most old plaster is firm, but there are two hollow patches beneath the window and a repaired electrical chase on one wall. No active staining is visible. The room will be empty and driveway parking is available. Photos show every wall, ceiling, window reveals and damaged areas. Please include loose-material removal, repairs, beads, bonding, skim finish, floor protection, waste removal and recommended drying time before painting.'
Frequently asked questions
What photographs help a plasterer quote?+
Include the complete surfaces, close views of defects, corners, openings, access and anything that needs protection.
Should I ask for skimming or replacement plaster?+
Describe the condition and desired finish. The contractor should explain what preparation or replacement is necessary after assessment.
Can plastering solve damp?+
New plaster does not resolve the underlying moisture source. Report staining or damp symptoms and address the cause before finishing.
When can new plaster be painted?+
Drying depends on thickness, background and conditions. Ask the contractor for project-specific guidance rather than fixing a date in advance.
What should an exterior rendering quote include?+
Ask for substrate preparation, repairs, beads, reinforcement, complete render system, access, protection, weather limits, cleanup and warranties.
