Liquid screed for Ferndown extensions and garden rooms
The floors that suit liquid screed are new, insulated and open. In Ferndown, rear extensions and garden rooms added to post war homes fit that description, and so do the newer houses: 11% of the town's homes were built between 2000 and 2014, and 7% since 2015.
A floating liquid screed goes down from about 35mm over insulation in a home, and needs at least 25mm over heating pipes, for a total of roughly 45 to 50mm. Sand and cement would need more depth, so the slimmer liquid floor makes it easier to match the existing floor where the extension opens into the house. It also dries sooner, at roughly a day per millimetre for the first 40mm, so a thinner floor reaches the flooring stage earlier.
It is also flat. Because it levels itself, SR1 or SR2 surface regularity is readily achievable, which suits the tiles, LVT and engineered wood that tend to go into open-plan kitchens. It hardly shrinks, which is why a big open floor can get by with a fraction of the joints a traditional screed would need. On an L-shaped kitchen extension, that can mean one continuous surface from the garden doors to the hall.
Two types are available. Calcium sulphate liquid screeds are common over heating in dry rooms, and cement based versions go where moisture is a concern. The calcium sulphate grades and aftercare are on the anhydrite flow screed page for Ferndown. Weighing up the two? Pumped versus traditional screed compares them point by point.
Pump access and drying in Ferndown homes
The mixer and pump need a standing place within hose reach of the room. At a detached house there is usually space at the front, and the hose can run down the side path to a rear extension. A garden room at the end of a long garden may need a longer hose run, so mention the distance when you ask for a price. Our pumping page shows what happens on the day; it is a laying service, so pumps and machines are not available to hire.
We go round the edge strip, membrane and insulation before anything is poured. A runny mix will seep through the smallest opening, so every gap in that build-up must be closed up. See insulation and membranes if you need them supplied as well.
Expect around a day per millimetre for the first 40mm of drying, with the pace dropping off beyond that; keep the room warm and aired to help it along. Walking across a Ferndown garden room a day or two after the pour is one thing and putting a finish on it is another, which is why we test the floor first. For heated floors, see our Ferndown underfloor heating screed page.
