Floor Levelling and Self Levelling Screed in Merton

A pour of self levelling compound is how we flatten bumpy concrete floors and screeds in Merton before LVT, vinyl, large tiles or engineered wood go on top. Merton mixes old houses with busy town centres: shop and office refits in Wimbledon, the largest, and in Mitcham and Morden, while extensions on older homes leave joins between old and new floors that need blending.

Refits in Wimbledon, Mitcham and Morden town centres

A shop or office changing hands usually needs a new floor finish, and the base under the old one is rarely ready for it. Old adhesive, patched areas, cable channels and small changes in level where counters or partitions stood all have to be dealt with. In Merton that work is spread across the three town centres, with Wimbledon the largest and Mitcham and Morden the other two.

New space is coming as well. The Clarion estate programme includes about 9,000 square metres of commercial and community space, and new units like those often need levelling between the shell and the tenant's finish.

The yardstick is BS 8204, which uses a 2m straightedge and looks at the largest gap underneath. For SR1 that gap can be 3mm at most; SR2 allows 5mm, SR3 10mm. For thin sheet vinyl in a shop or office, SR1 is often what the maker asks for. A layer of compound, normally from 2mm to around 10mm thick, gets the floor inside those limits, and fast drying products keep a shop refit to its dates.

Preparation comes first. The floor is cleaned back to sound material through our floor preparation service, sometimes with grinding or shot blasting. Priming follows, with a product matched to the base, since old tiles, calcium sulphate, sand and cement and bare concrete do not all take the same primer. For a whole new floor on a larger unit, our commercial screeding service in Merton covers it.

Blending old and new floors in Merton houses

Where a Victorian terrace or inter-war house has been extended, the new floor and the old one rarely meet perfectly. A small step or slope at the opening shows up under LVT or large tiles. Levelling compound can blend the two, as long as the difference is within the compound's range.

Solid floors in older homes are another candidate. About 11% of the borough's homes date from 1945 to 1972, and floors of that period are commonly sound but uneven after years of patching. Levelling brings them flat enough for modern finishes without the drying time of a new screed.

Knowing when not to use compound matters just as much. If a floor really needs replacing, compound will not save it, and a pour that is too thick may crack and lift. If a floor is badly out, hollow or breaking up, relaying it is the honest answer, and our sand and cement screed page for Merton covers that.

Compound only stays down on a clean, primed base, so we check the substrate before quoting. If the job is in Kingston upon Thames, see levelling floors in Kingston.

FAQs

Floor Levelling in Merton: your questions

What does SR1 mean for a new LVT floor?

BS 8204 grades floor surfaces by regularity, and SR1 is the class where a 2m straightedge shows a gap of 3mm or less. Many LVT and thin sheet vinyl makers require it, because any dip or ridge shows through the finish. We check the floor and level it with compound to meet that class.

Can levelling compound fix a step between an extension and the old floor?

Often, if the step is within a compound's range, usually up to around 10mm. It is feathered across the join to leave one flat surface. A larger difference usually needs a screed on the lower side instead, so we measure before recommending an approach.

How soon can flooring go down after levelling a Wimbledon shop?

It depends on the compound, the depth and the covering. Fast drying products are designed to keep a shop refit on programme, so we pick one to suit the opening date and confirm in writing how long the floor needs before the flooring contractor starts.
