Full House Wall Re-Skim by a Plasterer in Croydon – Lambeth South London

This project was carried out at a Victorian terraced house in Lambeth, South London — a short distance from the CR0 postcode area we regularly cover in Croydon. The property featured the typical characteristics of its era: tall walls, ceiling roses, and timber-framed door surrounds. Several rooms across the house were in need of replastering, with the walls showing widespread failure of the original textured plaster coating. The rooms had been partially stripped out and furniture wrapped or removed ahead of our visit, indicating the client was mid-way through a broader home renovation.

The first image shows a wall surface covered in heavy textured plaster — a coarse, stippled finish consistent with a sand-and-cement or perlite-based spray texture commonly applied in the 1970s and 1980s. A large section of this textured coating had already partially delaminated and peeled away from the substrate, exposing the smoother plaster beneath and leaving a ragged, uneven edge running vertically down the wall. A spotlight fitting had been removed, leaving an open recess in the wall. Protective dust sheeting was taped across the doorway and window areas, and cardboard was laid at the base of the walls. The second image shows a completed ceiling skim — trowelled flat with a light sheen still visible indicating the plaster had recently been applied and was in the process of drying.

The scope of work covered a full wall re-skim across multiple rooms within this Victorian terraced property in Lambeth. The existing textured wall surfaces — a coarse, pitted coating that had been applied over the original plaster — were either mechanically removed or prepared as a substrate for re-skimming, depending on the condition of the underlying plaster in each room. Where sections had already delaminated and peeled, the loose material was cut back to a firm edge before any skimming began. Electrical recesses left by removed spotlight fittings were made good with bonding plaster and allowed to set prior to the main skim coat being applied. The ceilings were also addressed as part of the wider re-skim programme — the second image clearly shows a freshly skimmed ceiling, still wet, surrounded by white-painted plaster coving typical of a period property. Walls were skimmed with two coats of multi-finish plaster — a scratch coat to build out the surface and fill texture, followed by a tightened finishing coat worked to a flat, even plane. Dust sheets were used throughout to protect flooring and adjacent surfaces, with green masking tape applied to door frames and window boards to protect the timber.

Before any plaster was applied, the delaminated textured coating was cut back and removed from the affected areas. The exposed substrate was checked for suction and stability. A diluted PVA bonding solution was brushed across the bare plaster sections to control suction and prevent the finish coat from drying too rapidly. Open electrical recesses left by the removed spotlight fittings were packed and filled with bonding plaster, then scored and allowed to firm up. Green masking tape was run along all door frames, window boards, and coving edges to achieve clean lines. Dust sheets were laid across all floor areas and furniture was either removed or wrapped in protective polythene sheeting.

Once the preparation was complete and the PVA tack had reached the correct stage — tacky but not fully dry — the first coat of British Gypsum multi-finish plaster was applied across the wall surfaces using a wide plastering trowel. This scratch coat was worked into the textured surface to fill the coarse profile left by the existing stipple finish, building the wall out to a consistent depth. The plaster was ruled off with a feather edge to establish a flat plane before the surface began to stiffen. As the scratch coat reached the right firmness, the finishing coat was applied and trowelled out in broad, overlapping passes to close the surface. The trowel was kept clean and dampened between passes to avoid drag marks. On the ceiling — visible in the second image — the same two-coat multi-finish process was used. The wet plaster is clearly visible with the characteristic dark, wet sheen of freshly applied multi-finish still showing across the ceiling plane. The coving surrounding the ceiling was masked and left intact, preserving the period character of the room. Once the final coat reached the correct stage of set, the surface was polished tight with a clean, damp trowel to close any remaining pin holes and produce a flat, paint-ready wall surface.

The principal challenge on this project was the failing textured wall coating. The stipple or spray texture that had been applied over the original plaster had lost adhesion in several areas, with one large section already peeling away from the substrate in a vertical strip. Simply skimming over the remaining texture risked trapping hollow sections beneath the new plaster — areas that would eventually crack or blow. The removed spotlight fitting also left a recess in the wall that needed to be built back flush before skimming could proceed across the full wall face without an indentation showing through the finish.

All loose and delaminated textured plaster was cut back to a firm edge using a bolster chisel, ensuring nothing hollow remained beneath the new skim. The boundary between the stripped area and the remaining texture was feathered back to avoid a hard ridge telegraphing through the finish. The spotlight recess was packed with bonding plaster and built out flush with the surrounding wall, then keyed and left to firm before the multi-finish was applied over the top. By treating the wall in a methodical sequence — cutting back, bonding, filling, then skimming — the finished surface was brought to a consistent flat plane with no visible signs of the underlying repairs.

The second image shows the ceiling of one of the rooms immediately after the skim coat was completed — the plaster is still wet and darkened, with the flat, even surface clearly visible across the full ceiling span. The coving border around the perimeter has been kept clean and sharp, with the masking tape protecting the painted edge. The wall surfaces across the property were brought back to a flat, even plane, free from the coarse texture that had dominated the rooms previously. The plaster was left to cure fully before the client proceeded with decoration.

The client was mid-renovation on this Lambeth terraced house and needed the walls and ceilings brought to a paint-ready condition before decorators could move in. By completing the full wall re-skim across the property in a single mobilisation, the project kept the renovation on schedule. The rooms were left with flat, stable plaster surfaces ready for mist coat and paint. The client confirmed they were happy with the pace of the work and the standard of the finished plaster, and asked for a quote to cover additional rooms at the rear of the property.

Skimming over a failing textured surface without first cutting back the delaminated sections is one of the most common causes of plaster failure within two to three years of a replastering job. A plasterer who understands substrate assessment will identify hollow sections by sound — tapping the wall to find areas where the existing plaster has lost its key — and cut these back before any new material is applied. Attempting to skim directly over loose or blown texture simply relocates the problem beneath a new coat of plaster. The same principle applies to open electrical recesses: packing these flush with bonding before skimming prevents indentations and cracking around the edges of the repair.
