Plastering service
Full re-plastering, backing coats and finish plaster for renovations, extensions, new builds and commercial interiors — applied to a consistent, decoration-ready standard.

Quick answer
Plastering covers preparing the background, applying a backing coat where the wall needs building out or levelling, and applying a finish coat that is trowelled smooth for decoration. Brellon carries out plastering on brick, block, plasterboard and previously plastered surfaces in homes and commercial buildings across London and the South East.
Most plastering problems start behind the finish coat. Before we plaster we assess what the wall or ceiling is made of, how absorbent it is, whether it is sound, and how far out of line it runs. That decides whether a surface needs bonding, PVA or a proprietary primer, beading on corners and openings, or a full backing coat before the finish goes on.
On older buildings we check for hollow, blown or salt-damaged plaster and remove it back to a sound edge rather than plastering over it. On new blockwork and brickwork we set out beads and grounds so that reveals, corners and ceiling lines finish straight and square.
Where walls are uneven, stripped back to masonry or need building out, we apply a backing coat such as a gypsum browning, bonding coat or a sand and cement scratch coat, depending on the background and where the wall is in the building. Once it has taken up correctly it is keyed and finished with a multi-finish or board-finish plaster.
Finish coats are applied in two passes and trowelled up as the plaster sets, leaving a flat, closed surface that can be mist-coated and decorated once it has dried.
In homes, plastering is usually part of a wider renovation, extension or loft conversion, so we coordinate with builders, electricians and plumbers around first and second fix. On commercial projects we work to the main contractor’s programme and specification, with RAMS, supervision and floor-by-floor sign-off.
Our process
We inspect the backgrounds, measure the areas and confirm the finish you need.
Floors, windows, joinery and fixed items are sheeted and taped before work starts.
Loose material is removed, beads are fixed and surfaces are primed or bonded.
Backing coats and finish coats are applied and trowelled to a smooth, flat finish.
We clean down, remove waste and give drying and decorating guidance.
Areas
Plastering for residential and commercial clients throughout London, Essex, Hertfordshire, Cambridge, Cambridgeshire, Surrey and surrounding areas.
A finish coat on plasterboard typically dries in two to four days. Finish over a backing coat usually takes one to two weeks, depending on thickness, ventilation and time of year. Plaster is dry when it has turned an even, light colour with no dark patches.
Yes, if the existing plaster is sound and well bonded. We check for hollow or blown areas first. Sound surfaces can be prepared and skimmed; failing areas are cut out and patched or the wall is re-plastered.
Please clear rooms where possible. Anything that cannot be moved is covered and protected, and floors are protected throughout.
