Together with the correct manifold locations and balancing and pressure testing of your system prior to screed is extremely important. Costs that are cut in the preparation and installation of underfloor heating will be costly in the future, you only put your floors in once and you wouldn’t want to have to dig them back up.

Easyflow Liquid Floor Screed

Q. What depths are recommended?
A. Fully Bonded 25mm, contact with substrate/unbounded 30mm, over insulation/acoustic matting 35mm domestic and 40mm commercial. Over Underfloor Heating 30mm covering over top of the pipes.


Q. Are joints necessary?
A. Up to 400sqm can be laid without an expansion joint, though it is advisable to have a bay joint with compressible material in weak spots such as doorways.

Q. How long before I can walk on the floor?
A. The screed can be walked on 24 to 48 hrs after the installation dependant on site conditions.


Q. How long before I can tile?
A. Under like for like conditions easyflow screed dries at the same rate as traditional sand and cement screed approx. 1mm/day up to 40mm of thickness. This increases for screeds thicker than 40mm and in poor drying conditions. When the screed is dry the you can tile, but it is important to have all the moisture out of the screed as the tiles will not bond with the adhesive.


Q. Is it true that I have to prime the screed?
A. Yes, if any adhesive is used for your selected choice of flooring, it is recommended to use an epoxy primer to create a barrier between any cement based adhesive and the gypsum based screed. Before this is applied it is vital that the floor is lightly sanded or scraped to key in the primer.

Q – What depth do I need to allow for liquid screed over UFH?

A. Ideally you need to leave a minimum depth of 50mm, we can also supply a thermally guaranteed screed called Thermio+ that can be laid at 40mm.


Q – How long does liquid screed take to dry?

A. In good site conditions you will be able to walk on the floor within 24 to 48 hours. You can load the floor with stairs, kitchens, partition walls etc. after 7 days.

The screed must be completely dry before installing your final floor finishes, the product will dry naturally at a rate of 1mm per day up to 40mm, any depth above this will dry at a rate of 0.5mm per day. So for example, if your liquid screed was laid at 50mm it will be naturally dry in 60 days.

If your liquid screed is laid over underfloor heating then you can start to force dry the screed 7 days following placement, we would then recommend a 3 week heating and cooling  cycle of your UFH system.

It is vital that you test the floors’ moisture content before applying your final floor finishes.


Q – Do you just supply the liquid screed or do you lay it as well?

A. As this is a specialist product you must be an approved installer before you can buy the product. Our service is to supply, pump and install the liquid screed. We will also carry out a separate site survey before the pour to check access, floor preparation and levels required.


 Q – Do you have per square metre for liquid screed?

A. We always price on a project by project basis, this is because the rate we buy the screed at changes depending on how close your project is to the nearest plant, we also price for the right amount of labour and how long you will need the pump for.

For a no-obligation quote, all we require is the floor area and proposed depth of the liquid screed and the location of the project.
