Ceiling Replacement & Full Wall Re-Skim in a Victorian Terrace in Newham

This project took place in a Victorian terraced house in Newham, E6. The property is typical of the area — a period terrace likely built in the late 1800s, featuring original wide floorboards, a distinctive curved bay window with an arched surround, and solid brick walls. The room worked on appears to be the front reception room, which had been stripped back completely as part of a wider refurbishment. All original plaster had been removed, leaving bare brick walls and exposed ceiling joists throughout.

The before photograph tells a clear story. All existing plaster had been hacked off the walls, leaving exposed red brick across every surface. The ceiling had been fully stripped back to bare timber joists — no plasterboard, no lath, nothing remaining overhead. The curved bay window recess presented additional complexity, as the arched surround required careful plastering around a non-standard shape. Debris covered the original floorboards and dust sheets were laid down in preparation. The room was essentially a shell, requiring a complete plastering solution from the ceiling joists downward before any decorating could begin.

The scope of work for this front reception room was extensive, covering both ceiling and all four walls from scratch. Starting from the top, new 12.5mm plasterboard was to be fixed directly to the exposed ceiling joists to create a flat, level substrate ready for skimming. Once the ceiling was boarded and skimmed, attention turned to the walls. With all plaster removed down to bare brick, each wall required a full sand and cement scratch coat or bonding coat to build up the base layer before a finishing skim could be applied. The curved bay window alcove needed individual treatment — the arched plaster surround was carefully profiled and the inset walls skimmed to follow the curve cleanly. The arched reveal between the main room and bay also required plastering to maintain a consistent line with the surrounding walls. Working around the existing radiator and skirting board positions was factored into the plan from the outset. The full scope included: new plasterboard ceiling fixed to joists, full ceiling skim, bonding coat to all bare brick walls, finishing skim coat to all walls, and plastering of the bay window reveal and arched surround. The project required a minimum of two plasterers working across two to three days to maintain a workable schedule.

Before any plaster was mixed, the room was thoroughly prepared. Dust sheets were laid across the original floorboards and all electrical sockets were isolated and masked. The exposed ceiling joists were checked for level and any protruding nails were punched back flush. New 12.5mm plasterboard sheets were cut to size and fixed to the joists using drywall screws, with joins staggered to reduce the risk of cracking. All bare brick walls were brushed down to remove loose dust and debris, then treated with a diluted PVA bonding solution to reduce suction and improve adhesion before the bonding coat was applied.

With the ceiling plasterboard fixed securely to the joists, the plasterer applied a neat skim coat of multi-finish plaster across the full ceiling. The skim was worked in sections — laying on from one end and then cross-trowelling back to achieve a flat, even surface. The trowel was kept damp throughout to allow the plaster to be polished off cleanly as it stiffened. On the walls, a bonding coat was applied across the bare brick surfaces in sections, building the base layer up to a consistent depth of approximately 8–10mm to account for the uneven brick face. This was left to partially set and then scratched with a devilling float to provide a key for the finishing coat. Once the bonding coat had firmed up overnight, the finishing skim was applied — two coats of multi-finish, a scratch coat followed by a tightening coat, worked together using a steel trowel and feathered back to a flat finish. The arched bay window surround was formed carefully using a small trowel and edging tool to follow the curve, with the plaster built up in layers to achieve a clean, consistent profile. The reveal inside the bay was skimmed last, trowelling into the corner from both the bay and the main room to maintain a straight, sharp internal angle. Throughout the process, site lights were used to rake across the walls and ceiling to identify any low spots or trowel marks before the plaster fully set.

The primary challenge on this project was the curved bay window and its arched plaster surround. Victorian bay windows with arch details are notoriously difficult to plaster neatly — the curved profile demands that plaster is built up gradually in thin layers rather than applied in a single coat, as thicker applications tend to sag or crack on curved surfaces before they can be supported. The second challenge was the variance in the brick wall suction. In some areas, particularly toward the base of the walls where old damp may have been present, the brick absorbed the bonding coat at a different rate to the upper sections, requiring careful monitoring to ensure even adhesion across the full wall height.

To address the arched bay surround, the plaster was applied in two thin build-up coats rather than one heavier application, allowing each layer to partially firm before the next was added. This prevented sagging and allowed the curve to be refined gradually with a small gauging trowel. For the variable suction on the brick walls, a second wash of diluted PVA was applied specifically to the lower sections of the wall before the bonding coat was laid on, equalising the absorption rate across the surface. The bonding coat was then applied in a consistent layer and monitored during the set to ensure no areas were pulling away from the brick face before the finishing skim was applied.

The second photograph shows the room mid-way through the plastering process, with the fresh multi-finish skim clearly visible across the ceiling and the upper sections of the walls already receiving their finishing coat. The warm amber tone of the freshly applied plaster contrasts with the remaining bare bonding coat on the right-hand wall, showing the sequence of work progressing across the room. By completion, every surface — ceiling, walls, bay reveal and arched surround — had been skimmed to a smooth, flat finish and left ready for mist coat and decoration. The bay window arch was restored to a clean, defined profile consistent with the original character of the Victorian property.

The client, who was refurbishing the property before letting it, now has a front reception room that is fully plastered from joists to floor — ready for mist coat, painting and finishing. The ceiling is flat and solid with no visible board joins. The walls are evenly skimmed with no hollow spots or bonding coat showing through. The bay window arch, which had been a concern from the outset, was returned to a clean curved profile that sits in keeping with the period character of the house. The room is now ready to move forward with the wider refurbishment programme.

In a stripped-back Victorian property like this one in Newham, the plastering demands go well beyond a standard re-skim. Bare brick walls have inconsistent suction, which means a plasterer needs to manage the bonding coat carefully to avoid delamination. Ceiling joists must be checked for level before plasterboard is fixed, or the finished ceiling will reflect every dip and rise. The curved bay window surround requires experience with profiling plaster around non-standard shapes — rushing this will result in cracking as the plaster cures. London Plastering Service has over a decade of experience working on period refurbishments across East London, and this type of full-strip project is handled routinely and methodically.
