Façades and plastering: the step-by-step guide

The substrate, finish standard and drying requirements determine how plastering is prepared and scheduled.

An overview of preparation, construction and handover. The exact sequence depends on your property, design and scope. Structural work and installations require a project-specific assessment.

Define the scope firstExterior work also involves weather, scaffolding and facade junctions. Indoors, protection and coordination with painting or wallpaper matter. Use a material system appropriate to the application.

Plastering and rendering in 10 steps

  1. Desired finish

    Establish whether the work concerns interior walls, ceilings or an exterior façade and agree the intended result.

  2. Survey the substrate

    Have existing layers, adhesion, moisture marks and cracks assessed.

  3. System and finish level

    Choose appropriate materials, texture and finish, distinguishing between preparation for wallpaper and for paint.

  4. Quote and access

    Specify the areas, repairs, work at height, profiles and connections.

  5. Protect and repair

    Clear the work area, protect surrounding elements and address the agreed defects.

  6. Preparation

    Prepare the substrate for the selected material system.

  7. Apply the plaster or render

    Apply the agreed layers and finish, paying attention to corners and connections.

  8. Drying and conditions

    Follow the product requirements for drying and working conditions, including the weather for exterior work.

  9. Assess the finish

    Compare flatness, texture and transitions with the agreed standard.

  10. Handover to the decorator

    Agree when wallpapering or painting can begin and retain details of the materials used.

What should you prepare for the site visit?

Provide dimensions, existing finishes and the desired result for each room or facade area. Mention damp marks or cracks. Choose the final wallpaper or paint finish early enough to agree the plasterer's handover standard.

Which documents should you keep?

Record treated surfaces, materials and any work remaining for the next trade. Have the substrate assessed for readiness before the next layer is applied. Agree how colour, texture and junctions will be reviewed.

Frequently asked questions

Can painting start immediately after plastering?

The substrate must be suitable for the chosen finish. Have moisture, drying and product requirements assessed; do not set a fixed waiting period without that information.
