Flat floors for Sunbury-on-Thames offices and research buildings
Offices and research space set tighter flatness targets than most homes. Under BS 8204, the class is set by the biggest gap beneath a 2m straightedge: 3mm or less makes SR1, 5mm SR2 and 10mm SR3. SR1 is the class many thin sheet finishes and lab floor coverings demand, and raised access floors sit well on a base that is flat and sound.
A refit on Sunbury Common, where offices, shops and hotels cluster near Sunbury Cross, usually starts with the old covering lifted and adhesive left behind. That residue has to come off before any compound goes down, and on a hard slab concrete floor grinding is the usual way to do it. Primer comes next, picked for what lies beneath, since concrete, calcium sulphate and sand and cement are each primed differently.
Compound normally runs 2mm at its thinnest to about 10mm, and some products can be poured thicker. Fast drying products keep a refit moving, which matters when a business is working around the job. Splitting an office floor near Sunbury Cross into zones keeps part of the building working while we level the rest.
Larger commercial projects sometimes need more than a skim. Some floors are simply too far gone, past what compound can fix or crumbling underneath, and those need fresh screed through our commercial screeding work.
Smoothing Sunbury Common flats and extension joins
Terraced houses make up 24% of homes in Sunbury-on-Thames, and with the flats and high-rise conversions on Sunbury Common these homes are where levelling before new flooring tends to come up. When a flat is refitted, the old screed often has dips, ridges or patched areas that would show through LVT or crack a large tile. A levelling coat fixes that in a few millimetres without raising the floor much.
In Lower Sunbury the problem is usually the line where a new extension meets the original house. Even when both are close to level, a small lip at the join will telegraph through a long run of engineered wood. Feathering compound across the join and the old floor gives one continuous surface.
There is a limit. Pile compound onto a floor that ought to be rescreeded and sooner or later it cracks and lets go of the base. Where a Sunbury floor is out by over roughly 10mm, or loose under the surface, we tell you straight and quote for new screed. A thinner product such as latex screed suits floors that only need a few millimetres. Nearby, our floor levelling page for Hounslow covers the same work.
