Liquid flow screed is the industry standard in floor screeds. This type of flooring is made from inert fillers like sand added with a binding agent such as cement but normally calcium sulphate.
It is also known as self levelling screed or a calcium sulphate screed.
Simple in its preparation this new form of flowing screed is suitable for light domestic use in under 24-48 hours after installation. It only need to be 40mm thick and 50mm over underfoor heating.
It is pumped in at such a rate that 100 meters can be layed in approximately 40 minutes, cutting down on labour costs.
Good to go!
The screed is then pumped directly onto the floor and heating pipes. Once fully pumped the surface is levelled with a dapple bar.
On average, a drying time of 4-6 hours should be left before any foot traffic is allowed onto the floor screed. We recommend underfloor heating shouldn’t be switched on for at least 14 days after application. After this time, it should be turned on to a maximum of 15°C, and then gradually turn it up by no more than 5°C each day to reach desired temperature. This is to avoid thermal shock to your screed.
The final phase
Depending on your choice of the final floor covering, we may need to add a finishing layer prior to the application of the floor covering. This is normally if PVC or linoleum is your chosen covering.
Finally, 7 to 10 days later, the screed is sanded to remove any laitance that is left on the surface. This is in preparation to having your floor tiled or whatever option you choose to go for.
How do we lay your screed?
Before applying your screed, we ensure the surface is dry and free from contamination and other impurities. All dust and debris is vacuumed from the surface.
Surfaces that contain small holes or other irregularities and differences in height are pre-levelled before installation of your screed.
A damp proof membrane (DPM) is then laid on top of the concrete base.
All heating pipes (If chosen) are firmly clipped down and stress relief joints are placed around all walls, pillars and other uprights.
