Full House Re-Skim by a Plasterer in Southwark – Hallway & Throughout

This project was carried out at a Victorian terraced house in the Lambeth and Southwark border area of South London. The property had recently undergone significant renovation work, including the installation of a new composite front door and a narrow side window fitted into the door reveal. The hallway, which serves as the first impression of the home, had been stripped back to bare plasterboard in preparation for a full re-skim throughout the property. Recessed downlights had already been fitted into the ceiling prior to our team starting on site.

When our plasterers arrived, the hallway walls had been taken back to bare plasterboard following internal works. The ceiling showed visible signs of damage — old plaster had blown and partially detached in several areas around the recessed light fittings, leaving the ceiling surface uneven and patchy. The door reveal and window surround had been newly boarded with fresh plasterboard as part of the door replacement, leaving raw exposed board requiring skimming. The existing ceiling plasterboard showed taped joints that had not yet been skimmed, and the overall wall surfaces were porous and unprimed, requiring a PVA bonding wash before any skim coat could be applied.

The scope of work covered a full house re-skim, with this image capturing the entrance hallway as part of the wider project. Specific work included: re-skimming all walls throughout the hallway from floor to ceiling using British Gypsum multi-finish plaster; skimming the newly installed door reveal and window reveal to the side of the composite front door; re-skimming the hallway ceiling around the existing recessed downlights, working carefully around the fittings to maintain flush, level surfaces; applying two coats of multi-finish — a scratch coat to build depth and a finishing coat to bring the surface to a smooth, paint-ready finish; and treating all bare plasterboard surfaces with a diluted PVA solution prior to skimming to reduce suction and prevent the skim coat from drying too rapidly. The wider project extended this same re-skim process to all rooms throughout the property, including bedrooms, reception rooms and landings, making it a comprehensive full house re-skim rather than isolated room work.

Before any plaster was mixed, all bare plasterboard walls and ceilings were treated with a PVA bonding agent diluted at approximately 1:4 ratio and allowed to become tacky before the first coat was applied. This step was essential given the highly porous nature of new plasterboard. The recessed downlights in the ceiling were masked off and protected to prevent plaster contamination of the fittings. The new door reveal and window reveal plasterboard edges were checked for level and any gaps at the board joints were filled and taped before skimming commenced. The floor was sheeted down with dust sheets to protect the newly laid marble-effect floor tiles visible at the base of the hallway.

The hallway walls were skimmed in two coats of British Gypsum multi-finish plaster. The first scratch coat was applied at approximately 2–3mm thickness using a steel trowel, working from the top of the wall downward to avoid marking freshly plastered lower sections. Once the scratch coat had firmed up sufficiently, the finishing coat was applied and worked back using a clean, dampened trowel to consolidate the surface and close the finish. The door reveal and window reveal received the same two-coat process, with particular care taken at the internal angles to keep edges crisp and square using an angle bead trowel. The ceiling was worked around the recessed downlight housings, with the plaster feathered neatly up to each fitting without undercutting or ridging. Once the finishing coat reached the correct stage of firmness, the walls were polished back with a wetted trowel to produce a flat, smooth surface ready to accept mist coat and emulsion paint.

The main challenge on this project was working around the newly installed composite door and its side window panel within a narrow hallway. The door reveal itself had been boarded at an angle to accommodate the glazed side panel, creating an irregular internal corner that required careful setting out before skimming. Additionally, the ceiling around the recessed downlights had areas of blown and detached original plaster sitting alongside intact sections, meaning the transition between old and new plaster needed to be managed carefully to avoid visible ridges or steps in the finished ceiling surface.

To address the irregular door reveal geometry, the angles were first checked with a spirit level and any misaligned board edges were packed out before skimming began. The internal corners of the reveal were formed using a small angle trowel to keep the reveals straight and uniform. On the ceiling, the areas of blown plaster were carefully removed back to a sound edge, and the resulting recess was built up with bonding coat before the overall skim was applied across the full ceiling, blending the repaired sections flush with the surrounding surface. This approach eliminated any stepping or ridging around the downlights.

The hallway walls emerged from the re-skim process with flat, even surfaces across all faces, including the door reveal and window surround which now read as clean, sharp-edged reveals. The ceiling, despite the challenges around the downlights, finished level with no visible ridging or step between repaired and original sections. The warm tone visible in the photograph is the natural fresh multi-finish plaster colour — indicating the skim coat had been applied evenly and was drying uniformly across all wall surfaces, a sign of consistent coat thickness and correct suction control through the PVA preparation.

The client, who was refurbishing the property prior to letting it, was able to proceed directly to the mist coat and decoration stage within 72 hours of the plastering being completed. The full house re-skim across all rooms was completed within the agreed programme, allowing the decorators to follow immediately behind our team. The hallway in particular — being the first space a tenant sees — presented cleanly with no visible defects, patching or unevenness across the walls or ceiling.

A full house re-skim across a property with newly installed joinery, recessed electrics and irregular reveals is not a straightforward job. Applying skim plaster directly to unprepared bare board without PVA treatment causes the coat to dry too fast, resulting in cracking and delamination within months. Working around recessed downlights without proper masking risks damaging the fittings and creates ragged edges that are impossible to paint out neatly. Correctly forming internal angles on door reveals requires the right tools and enough experience to keep reveals straight without the aid of rigid beads on every edge.
