How Liquid Floor Screed Is Installed — Step by Step

Liquid screed is pumped, not laid by hand. This is what actually happens on site, from the truck arriving to a floor you can walk on — filmed on one of our own pours.

A day on site with our own team and pump — arrival, setup, pour, dappling and finished floor.

How is liquid floor screed installed?

Substrate preparation. The base must be clean, dry, and structurally sound. Edge insulation strips are fixed around the perimeter. UFH pipes are pressure-tested before pour.

Pump setup. Our truck-mounted pump is positioned outside the building. Hoses are routed to the pour area — access through a window or door is sufficient.

Pour. The screed mix is pumped continuously into the area. Our installer guides the hose and rakes where necessary to ensure even distribution.

Dappling. A roller is passed over the surface to release any trapped air bubbles and ensure a consistent finish.

Curing. Doors and windows are closed for 24–48 hours to protect from draughts. The screed is covered with polythene in hot weather.

Drying. Drying times depend on depth and environment. See our drying times guide → for full guidance on ventilation and moisture content testing.

What we need from you on the day

Clear access from the road to the pour area, a water supply, and the property empty of trades while we work. If the pump needs a parking suspension we will tell you at quotation stage, because those take a few working days to arrange.

Underfloor heating pipes must be pressure-tested and holding before we arrive. We will not pour over an untested system — a leak found after the screed has gone down is a floor coming back up.

After the pour

Keep doors and windows shut for the first 24–48 hours so the surface does not dry too fast and craze. After that, ventilation is what drives drying. See the drying times guide → for depth-by-depth timings and how to test moisture content before floor coverings go down.
