A closer look at a finishing plaster used on interior walls and ceilings, and how the background affects application.
Where MultiFinish fits
British Gypsum Thistle MultiFinish is a finishing plaster used on suitable interior wall and ceiling backgrounds. It is intended to create a smooth surface for subsequent decoration.
Coverage is not the whole specification
The number of bags depends on area, thickness, waste and the surface. Follow current manufacturer data for coverage and suitability, and assess the background before ordering.
What the material is for
Materials are selected for a particular background and purpose. A finishing coat, a backing plaster, a render and a waterproofing system do different jobs. Check compatibility with the substrate rather than treating them as interchangeable.
Preparation and application
The surface must be assessed and prepared in line with the chosen system. Thickness, mixing, timing and environmental conditions can affect the result. Follow the manufacturer’s current instructions and seek professional assessment where moisture or structural movement is involved.
What happens afterwards
Allow the applied system to cure or dry as specified before adding paint or other finishes. Check whether additional primers, protective coats or maintenance are required.
Materials and background compatibility
A finishing plaster can create a smooth surface only when the substrate has been prepared to suit it. Different backgrounds may need different suction control, bonding or reinforcement, following the current product instructions.
Before ordering material, record the surfaces and approximate areas, then allow for openings and wastage in a quote. Coverage figures are estimates; background, application thickness and site conditions influence actual use.
Before you book
How do I request a quote?
Send your postcode, photographs of the whole area and close-ups of any damage. Explain what finish you want and whether other work is planned.
Can MultiFinish fix loose existing plaster?
No. An unstable background needs repair or removal before a finishing coat. The product is not a substitute for sound preparation.
