Wall Skimming & Full Plasterboarding by a Plasterer in Enfield – Southwark Case Study

This project was carried out on a Victorian terraced house in Southwark, south London — a property type commonly found across London boroughs including Enfield. The house had undergone a full strip-out prior to our arrival, with all existing plaster hacked off the walls and ceilings removed. Exposed bare brick walls and original floorboards were visible throughout the rooms, indicating the property had been taken back to its shell as part of a larger renovation programme before plastering could begin.

When the team arrived, multiple rooms were in a completely stripped-back state. Image one shows a bedroom with all old plaster removed, leaving bare concrete block walls fully exposed. Chunks of demolished plaster and debris were scattered across the original floorboards. A second room, visible in image five, revealed exposed London stock brickwork on every wall surface, with the ceiling lath and plaster completely stripped away, leaving timber joists exposed overhead. Electrical cables were routed along the walls, and the doorframe surrounds showed fresh timber studwork had been positioned ready for boarding. No surface in any room was in a condition suitable for direct skimming — every wall required a full plasterboard dry-lining installation before any finish coat could be applied.

The scope covered the full plasterboarding and skim coating of at least two rooms within this Victorian terraced property. The work included: fixing plasterboard sheets directly to all bare brick and concrete block walls across both rooms; plasterboarding the ceilings where the old lath and plaster had been stripped; taping all plasterboard joints with scrim tape before applying a bonding or base coat where required; applying a full two-coat skim of multi-finish plaster to all walls and ceilings throughout; ensuring all electrical back boxes were set flush and accommodated within the board thickness prior to skimming; protecting all existing floorboards with dust sheets throughout the works; and preparing all surfaces to a paint-ready standard. Images three and four clearly show the completed plasterboarding stage across walls and ceiling of one bedroom, with all boards fixed, joints taped with orange scrim tape, and the room fully sheeted on the floor in advance of the skim coat. Bags of British Gypsum Multi-Finish plaster are visible on site alongside a plastering hawk, mixing bucket and gauging tools, confirming the materials staged ready for the finishing phase.

Before any plasterboard could be fixed, the rooms were cleared of all rubble and debris left over from the strip-out. Dust sheets were laid across the original floorboards in each room to protect them during the boarding and plastering stages. On the bare brick and block walls, a PVA bonding agent was applied to stabilise the porous masonry and improve adhesion where mechanical fixing alone was insufficient. Plasterboard sheets were then cut to size and fixed directly to the brick and block substrate across all wall elevations. On the ceiling, boards were fixed directly to the exposed joists. All board joints were reinforced with orange fibreglass scrim tape ahead of the skim coat, clearly visible across joints in images three and four.

With all plasterboard fixed and scrim-taped, the walls and ceilings were ready to receive the finish skim coat. British Gypsum Multi-Finish plaster was mixed to a smooth, lump-free consistency using a paddle mixer and applied directly to the plasterboard surfaces. The first coat — the scratch coat — was spread across the entire surface using a steel trowel, forcing the plaster into the recessed joints and building up an even base layer across each board. This coat was allowed to firm up slightly before the second finishing coat was applied and trowelled flat. As the plaster began to set, the surface was worked back with a damp trowel to close the face and consolidate the finish. The before-and-after comparison in image one clearly shows the transformation in the bedroom — from bare, rubble-strewn concrete block walls to smooth, freshly skimmed plaster walls and a flat ceiling, ready for painting. Image two captures a mid-skim stage in another room, where two walls have been freshly skimmed while the new plasterboard is still visible and awaiting its skim on the remaining elevations.

The primary challenge on this project was the sheer scale of the substrate preparation required before any plastering could take place. With every room stripped back to bare brick or concrete block, there was no existing surface to skim over — each wall had to be dry-lined from scratch. The exposed brick in the second room shown in image five was particularly uneven, with protruding mortar joints and varying brick faces that would have been impossible to skim directly without first establishing a flat plasterboard substrate. Routing existing electrical cables behind boards without damaging them or losing socket positions also required careful coordination during the boarding stage.

Plasterboard was fixed directly to the bare brick and block walls across all elevations, creating a consistent, flat substrate ready for skimming. Where the brickwork was particularly uneven, boards were shimmed or packed at fixing points to maintain a true, plumb face across the full wall height. All electrical back boxes were set to the correct depth within the board so that sockets and switches sat flush with the finished plaster face. Once the boarding was complete and all joints scrim-taped, the skim coat went on cleanly across every surface. The completed bedroom visible in image one confirms the approach worked — the walls and ceiling are flat, uniform and ready to paint without further remedial work.

The finished rooms show a complete transformation from stripped-out, debris-filled spaces to smooth, paint-ready interiors. The bedroom captured in image one demonstrates the end result clearly: flat, evenly skimmed walls and a flush ceiling with no visible board joints, ridges or hollows. The room went from bare concrete block — strewn with demolition debris — to a fully plastered space ready for decoration. Sockets are set flush, the ceiling is level, and the walls are plumb. The same standard was delivered across all rooms included in the project scope.

The client — a property owner undertaking a full renovation of this Victorian terraced house — was able to hand the rooms over to decorators immediately after completion. All walls and ceilings across the plastered rooms were flat, stable and fully cured within the agreed timeframe. The project was completed without damage to the original floorboards and with all debris cleared from site at the end of each working day. The client confirmed the plastered rooms matched the standard required by their decorator to proceed straight to mist coat and paint.

Plasterboarding directly onto bare brick and block is not simply a case of screwing sheets to a wall. Brickwork is rarely plumb or flat, and boards fixed without proper packing and alignment will telegraph those irregularities straight through to the finished skim face. Mixing plaster to the correct consistency, applying it at the right thickness and working it back at exactly the right point in the set cycle are skills that take years to develop. Rushing any stage — from boarding to taping to skimming — results in cracking joints, uneven faces or a finish that needs redoing before a room can be decorated.
