Full House Re-Skim Including Hallway & Stairwell – Plasterer Bromley

This project was carried out on a Victorian terraced house in South London, with the SEO focus serving homeowners in Bromley BR1 and surrounding areas. The property featured a narrow hallway and steep stairwell — a combination that is common in period terraced homes of this style and era. The original plaster had deteriorated significantly throughout the ground floor circulation areas, and the owner was undertaking a broader renovation that required all walls to be brought back to a sound, freshly skimmed finish before decoration could begin.

When our team arrived on site, the hallway walls had already been stripped back to bare brick and timber lath in several sections, with remnants of old painted plaster still adhering in patches. The upper stairwell wall showed a mixed substrate — part bare brick, part remaining old render — with visible score marks and residue from where plaster had been hacked off. Floor protection was already in place with green hard floor covering sheeting laid across the stairs and landing. The existing plaster was beyond re-skimming in its stripped state; it required a full bonding coat application before any finish skim could be applied.

The scope of work covered the full re-plaster of the hallway and stairwell walls from ground floor to upper landing. This included: - Applying a bonding coat across all stripped bare-brick wall surfaces in the hallway and stairwell to build up a stable key for the finish skim - Installing plastic angle beads to all exposed external corners, including the stairwell angle and door reveal edges, to create straight, durable arrises - Allowing the bonding coat to firm up fully before applying two coats of multi-finish — a tight scratch coat followed by a trowelled finish coat — across all walls - Skimming the ceiling area within the stairwell void where it met the upper hallway - Working around the existing staircase without removing it, requiring precise trowel work along the stringer and balustrade line - Tidying all transitions between the new skim and existing door architraves and skirting boards - Leaving all surfaces flat, scratch-free and ready for mist coat and decoration

Before any plaster was applied, all loose and delaminated old plaster was removed from the walls. The bare brick and block surfaces were brushed down to remove dust and debris, then given a diluted PVA bonding wash — one part PVA to four parts water — to stabilise the porous masonry and improve adhesion. Plastic corner beads were fixed to all external angles using bonding plaster before the main bonding coat was applied. Floor protection sheeting was kept in place throughout and extended with dust sheets at the base of the staircase. Electrical socket backs were checked and taped off ahead of plastering.

Once the PVA tack coat had gone tacky, a full bonding coat of Thistle BondingCoat was applied across all bare-brick wall sections using a hawk and steel float. This was scratched back with a comb scratcher to provide a mechanical key for the finish coat and left to firm to the correct consistency. With the bonding coat set, the finish skim was applied in two passes using British Gypsum Thistle Multi-Finish. The first coat — the scratch coat — was laid on at approximately 2–3mm and ruled off with a feather edge to level the surface across each wall. The second finish coat was applied before the first had fully set, allowing the two coats to be worked together and trowelled smooth. A clean water brush was used to open up the surface at the right stage, enabling a final tight trowel pass to close the face of the plaster. The stairwell angle — where the ceiling soffit meets the upper wall — was cut in carefully by hand using a trowel and angle tool to produce a clean, straight internal angle without cracking. The transition between the new skim and the existing architrave timberwork was kept tight and clean throughout.

The main challenge on this project was working within a narrow Victorian stairwell with a steep staircase already in place. Reaching the upper sections of the stairwell wall required working from a combination of hop-up platforms and a stairwell plastering stilts setup, while ensuring no plaster splatter or damage occurred to the newly fitted timber stair treads below. Additionally, the substrate varied considerably — some sections were bare red brick, others retained patches of old sand-and-cement render — meaning the bonding coat thickness had to be adjusted wall by wall to bring all surfaces level before skimming.

To manage the varied substrate, our plasterer assessed each wall section individually before applying bonding. Where old render patches remained slightly proud, these were feathered into the bonding coat rather than hacked off unnecessarily, avoiding further disruption to the surrounding masonry. Temporary hop-up boards were positioned across the stair treads at different heights to allow safe access to all areas of the stairwell without leaning across the banister. All stair treads were double-sheeted with hard floor protection and dust sheets throughout the entire plastering process to prevent any contamination from splashed plaster or trowel water.

The finished walls across the hallway and stairwell show a flat, consistent skim coat with clean, sharp external angles at all corners and reveals. The before-and-after photographs in the collage clearly show the transformation from stripped bare brick with patchy old plaster to smooth grey fresh skim coats throughout. The internal stairwell angle between ceiling and wall is tight and uncracked, and the transitions against door architraves and skirting boards are neat. All surfaces were left ready for a mist coat of diluted emulsion before the client's decorator continued with the full redecoration of the hallway.

The client was midway through a full house renovation when we completed this phase of work. Having the hallway and stairwell walls freshly skimmed and ready for decoration removed a significant bottleneck from their programme — the decorator was able to start mist coating within three days of us completing. The client commented that the stairwell, which had looked like a building site for weeks, finally looked like a home again. They have since been in touch regarding re-skimming two of the upstairs bedrooms as the renovation continues.

Re-skimming a hallway and stairwell is one of the more technically demanding domestic plastering jobs. The angles are numerous, the access is awkward, and the substrate in period properties is rarely consistent. Applying finish skim directly onto unstabilised bare brick without the correct bonding preparation will result in the plaster pulling away from the wall within months. Getting the bonding coat thickness right across a mixed substrate — and then timing the two-coat finish skim correctly — requires experience that comes from repeated hands-on work on similar Victorian terraced properties across South London.
