Full House Re-skim & Media Wall Plastering by a Plasterer in Ealing

This project took place in a period property in Ealing, West London, W5. The living room was undergoing a full renovation, with the owners transforming the main reception room into a contemporary open-plan space. A custom-built media wall had been constructed by a joiner, complete with a wide linear electric fireplace, a central TV recess, and multiple built-in display alcoves on either side. The room featured a large sash window typical of older London properties, and the original ceiling required patching before the full skim could be completed.

At the point of our visit, the living room was mid-renovation. The walls had been stripped back and the new plasterboard media wall was freshly boarded but entirely unfinished, with all surfaces showing bare plasterboard and exposed timber frames within the alcove recesses. The ceiling had already received a base skim coat across the majority of its surface, but a row of recessed downlighter cut-outs were clearly visible as unfinished square patches running diagonally across the ceiling — each one at a different stage of patching with bonding coat applied but not yet brought flush. The concrete floor was bare and covered in plaster splatter, indicating active work throughout. The room was clearly stripped and ready for the final skim stage.

The full scope of work on this project centred on the living room of a period property in Ealing and covered three main areas of plastering. First, the ceiling required patching around a series of recessed downlighter apertures — approximately six to eight square cut-outs that had been left proud or recessed after the lighting contractor completed their work. Each patch needed to be brought flush with the surrounding ceiling surface before a final skim coat could be applied across the entire ceiling plane. Second, the newly constructed media wall required a full skim across all its plasterboard faces. This included the flat face of the media wall itself, the interior faces of each display alcove recess — left side stack of three alcoves, right side stack of three alcoves, and the large central TV recess — as well as the reveals and returns on each opening. The fireplace recess surround also required plastering to the inner reveals. Third, the adjacent walls in the living room that had been re-lined or patched as part of the wider renovation needed re-skimming to match the new media wall. The overall scope required careful sequencing so that the ceiling patches were completed and tightened before the ceiling final skim, and the media wall skim was timed to allow adequate drying time on the bonding coat beneath.

Before any skim coat was applied, all plasterboard joints on the media wall were taped with scrim tape to prevent cracking at the board joints once the plaster dried. The alcove recesses were checked for square and any gaps between boards and the existing walls were filled. The ceiling cut-outs from the downlighter installation were first filled with off-cuts of plasterboard cut to size and fixed flush with the surrounding ceiling board, then bonding coat was applied to bring each patch level with the ceiling surface. A PVA dilution wash was applied to the porous plasterboard surfaces across the media wall and ceiling patches and left to reach a tacky state before the skim coat was started.

The plastering was carried out in a logical sequence starting with the ceiling. Once the bonding coat patches around the downlighter apertures had dried sufficiently and been checked for flatness, a full skim coat of Thistle Multi-Finish was applied across the entire ceiling. The skim was applied in two passes — the first coat was laid on and spread to an even thickness, then while still green, a second tightening coat was applied and worked to a flat, consistent surface using a feathered action to blend the patched areas seamlessly into the wider ceiling plane. Attention then moved to the media wall. The flat face of the main wall received two coats of Multi-Finish, with the first coat applied vertically and the second coat cross-worked to eliminate any trowel lines. Each alcove recess was then skimmed individually — the back panel first, followed by the side returns and top and bottom reveals. The fireplace recess surround was worked carefully around the installed linear electric fire unit to avoid contact with the unit itself. The trowel was cleaned regularly between passes to prevent dry plaster contamination. Each section was finished with a clean water trowel pass to close the surface and achieve a consistent matt finish ready for paint. The floor was protected throughout with dust sheets, and the electric fireplace unit was masked off prior to any plastering beginning on the surrounding structure.

The primary challenge on this project was the ceiling. The downlighter apertures had been cut at varying depths by the electrician, meaning that each patch sat at a slightly different level relative to the surrounding ceiling board. Simply skimming over them would have created visible lumps or hollows in the finished ceiling. Additionally, the media wall contained multiple internal alcove recesses of different depths and widths, all requiring crisp, square arrises at the corners of each opening. Maintaining flat, plumb returns inside narrow recesses while also keeping clean external corners on the alcove faces required careful trowel control and multiple passes on each reveal.

To resolve the ceiling level discrepancies, each downlighter cut-out was individually assessed. Where the gap was shallow, bonding coat was built up in layers and feathered out to the surrounding surface before drying. Where the cut-out left a deeper void, a piece of plasterboard was cut and fixed flush before bonding coat was applied over the top. This staged approach ensured every patch was at the correct level before the full ceiling skim began. For the alcove recesses on the media wall, angle bead was fitted to all external corners to give clean, consistent arrises on every opening edge, and the internal corners of each recess were ruled off using a short feather-edge to achieve flat, square reveals throughout.

The finished living room showed a consistent, flat skim across the entire ceiling with no visible trace of the downlighter patches — each cut-out fully absorbed into the surrounding surface. The media wall presented a uniform pink-toned freshly skimmed face with crisp, well-defined corners on every alcove opening. The internal alcove surfaces were flat and ready for decoration, and the fireplace recess surround was neatly finished tight to the linear fire unit. All wall and ceiling surfaces were left in a ready-to-paint condition with a clean, closed plaster face throughout the room.

The client was mid-renovation on their Ealing period property and needed the plastering completed to allow decorators to follow immediately behind. With the ceiling patches resolved and the media wall fully skimmed, the room was handed back in a paint-ready condition within the agreed timeframe. The built-in alcoves and fireplace surround were finished to a standard that allowed the decorators to apply a single mist coat and then final finish coats without any additional remedial work. The client confirmed the timeline worked well with the wider renovation programme.

Skimming around a custom-built media wall with multiple recesses and a ceiling full of downlighter patches is not straightforward repair work. Each element requires a different approach — patching, beading, bonding, and final skim — and getting the sequence wrong leads to cracked joints or uneven surfaces that show through paint. An experienced plasterer in Ealing with knowledge of period properties understands how older buildings move and how to prepare mixed substrates correctly. Using the right bonding agent on each surface type and applying Multi-Finish at the correct consistency prevents common problems such as hollows, cracks at board joints, or a powdery finish that won't hold paint.
