Full House Re-skim by a Plasterer in Barking and Dagenham — Bay Window Living Room & Ceiling Overboarding

This project was carried out at a Victorian terraced house in Barking and Dagenham, RM8. The property features a distinctive bay window in the front reception room — typical of the terraced housing stock found throughout this part of East London. The house had not been replastered in many years and required a full internal re-skim across multiple rooms. The bay window recess added complexity to the ceiling geometry, requiring careful boarding and skim work around the angled soffits and returns above the window bay.

The existing plaster across the walls and ceilings had deteriorated significantly. The ceiling in the front bay window room showed clear signs of age — the original surface was uneven and no longer suitable for direct re-skimming without overboarding first. In the before photos, the ceiling can be seen with new plasterboard sheets fixed in a grid pattern, with visible board joints and jointing tape running across the surface. The walls, stripped back to bare substrate in places, showed old painted plaster and uneven sections. The bay window recess walls and angled ceiling soffits were particularly irregular, requiring extra preparation before any skim coat could be applied.

The scope of work at this Barking and Dagenham terraced house covered the front bay window reception room as the primary focus, with additional plastering work carried out throughout the rest of the property as part of the full house re-skim. In the main reception room, the ceiling was overboarded with 12.5mm plasterboard sheets fixed to the existing ceiling joists above. The boards were cut to fit neatly around the bay window geometry, with joints taped and jointed before skimming. The angled soffits above the bay window were also boarded and skimmed to provide a flat, consistent surface across the entire ceiling plane. The walls in the reception room were re-skimmed, with the plaster applied in two stages — a scratch coat to build up any low spots, followed by a finishing coat of multi-finish plaster. The bay window return walls were also skimmed to match. Throughout the rest of the house, walls and ceilings received a full re-skim using Thistle multi-finish plaster, with surfaces prepared using a diluted PVA bonding solution prior to application to ensure proper adhesion across the porous, aged substrate.

Before any plaster was applied, all loose and flaking material was removed from the walls throughout the property. The ceiling in the front room was overboarded, with the new plasterboard sheets screwed firmly into the joists above and all board joints reinforced with jointing tape bedded into a skim of bonding compound. The bay window ceiling returns were carefully measured and cut to follow the angles of the bay. All surfaces to be re-skimmed — including the bare plaster walls — were treated with a PVA bonding solution applied by brush and allowed to become tacky before the first coat of multi-finish plaster was applied.

Once all preparation was complete, the plastering began with the ceiling in the front reception room. The newly overboarded ceiling received its first coat of Thistle multi-finish plaster, worked across the full span of the boards and pressed firmly into the joints. The angled bay soffits were skimmed separately to ensure the plaster was properly worked into the corners where the angled returns met the main ceiling. After the first coat had begun to firm up, a second finishing coat was applied across the ceiling, trowelled tight and polished to a smooth, flat surface ready for decoration. The walls in the bay window room were then skimmed using the same two-coat approach — scratch coat first to level any irregularities in the substrate, followed by a finishing coat worked to a smooth, paint-ready surface. The bay return walls were skimmed to match. Throughout the rest of the property, each room received the same two-coat process using Thistle multi-finish plaster. The plasterer kept a gas heater running throughout the project to maintain ambient temperature and assist drying between coats — essential during cooler months to prevent the plaster from taking too long to firm up or from drying too quickly and cracking.

The main challenge on this project was the bay window ceiling geometry. Victorian terraced houses in Barking and Dagenham frequently feature these angled bay windows, and the soffits above the bay create a series of short, angled ceiling returns that must be overboarded and skimmed individually. Getting neat, straight arrises — the sharp edges where two plastered surfaces meet at an angle — on these returns requires careful board cutting and confident trowel work. Any deviation at these junctions would be immediately visible once the room is painted and lit from the side. The additional challenge of working across a full house meant managing drying times room by room to avoid returning to a surface that had already set.

To address the bay window geometry, each angled soffit section was templated individually and the plasterboard cut to fit precisely before fixing. Metal angle bead was applied to all exposed external corners on the bay returns to protect the edges and provide a straight guide for the trowel during skimming. This ensured the arrises came out sharp and true. Across the rest of the house, the team worked room by room in sequence, allowing each plastered surface to reach the correct firmness before returning to trowel off. The gas heater was used strategically to control drying conditions throughout.

The finished ceiling in the front bay window room is fully flat and consistent across both the main ceiling and the angled bay soffits, with sharp arrises at each junction. The walls throughout the reception room and the rest of the property have been brought back to a smooth, flat surface ready for paint or wallpaper. The overboarded ceiling, visible in the before photos as a grid of plasterboard joints, is now completely concealed beneath a trowelled, polished two-coat skim. The bay window returns sit flush with the main ceiling plane, giving the room a clean and well-proportioned appearance that does justice to the period character of the property.

The client — a homeowner in RM8 preparing the property for redecoration — was able to move forward with painting and decorating within a week of the plastering being completed. The overboarded and re-skimmed ceiling in the front room made the biggest visual difference, transforming what had been a tired and uneven surface into a flat, consistent plane. With all rooms re-skimmed in sequence across the project duration, the property was ready for its full redecoration and the client avoided the disruption of returning to individual rooms piecemeal.

Re-skimming an entire Victorian terraced house — particularly one with a bay window — is not a single-trade job. The ceiling overboarding must be done correctly before any plaster is applied, or the skim coat will fail along the joints. Getting the angles right on the bay soffits requires accurate templating and cutting, and the arrises must be properly beaded to stay sharp after drying. An inexperienced plasterer working on a full house re-skim may rush between rooms without allowing adequate drying time, leading to surface cracking or delamination.
