Office and shop fit outs in Mayfair and Soho
Mayfair and St James's are home to the headquarters of global companies, while shops and restaurants fill Soho and the streets around Oxford Street. When an office, shop or restaurant in these areas is refitted, the new floor finish is laid over whatever the last tenant left: adhesive residue, patched trenches, uneven tile beds and changes in level between rooms.
The work starts with preparation. Old adhesive and weak surface material are removed, often by concrete floor grinding, until the base is clean and sound. Then we prime, matching the product to the base, as concrete, sand and cement and calcium sulphate each want a different one. Only then does the compound go down. Skipping the primer, or using one meant for a different base, is a common reason for compound lifting or pinholing on the surface.
The target flatness is set by the finish. LVT and many thin sheet floors in a West End shop or office need SR1: run a 2m straightedge across and the biggest gap should be 3mm. SR2 allows 5mm, and the flooring maker's sheet says which class a finish needs.
Timing is usually tight. Fast drying compounds let the flooring contractor follow on quickly, and the pour can be planned in sections around the fit out programme. Where a space needs a full new screed, our commercial screeding service covers the larger job.
Uneven concrete in Churchill Gardens and mansion blocks
Flats in mansion blocks and post-war estates such as Churchill Gardens often need a levelling compound over uneven concrete before new flooring. 15% of Westminster's homes were built between 1945 and 1972, and floors of that age often fall short of the flatness a modern LVT or large tile demands.
Churchill Gardens itself was laid out between 1946 and 1962 by Powell and Moya. Where a flat on an estate like it is refurbished, the concrete floor is usually sound but has gentle rises and dips. A coat of compound between roughly 2mm and 10mm thick evens that out. Flats in mansion blocks are treated the same way: the concrete is checked for soundness, cleaned, primed and then levelled before the new floor goes down.
There is a limit. Piling on thick compound to rescue a floor that should be rescreeded tends to end in cracks and loss of bond. If a floor is broken, hollow or dips well beyond 10mm, a new sand and cement screed where the base has failed is the better answer, and we will say so before pricing compound. And if a solid floor just wants a skim, a few millimetres of latex smoothing screed could be all it takes.
