Step 1

Remove ALL dust and debris from the floor surface.




Step 2

Place insulation, ensuring ALL high/low points are removed from the sub-base so that the boards are laid flat.



Step 3

A polythene separating membrane is required with all liquid screeds. Lay the polythene and make sure that it is free from punctures and creases. Overlap the joints, then seal with duct tape to avoid leakages. Allow the polythene to continue up the walls to the full depth of the screed. Make sure that the polythene fits tightly into the corners, securing with additional tape if required.



Step 4

Place a 5/10mm expansion foam around the perimeter in all rooms using tape to secure it to polythene. The floor is now ready to pour liquid floor screed which will be able to secure the underfloor heating system and attach within the floor. Prepare the system with the highest standards possible to ensure that there are no issues down the line and to ensure that your system will require little to no maintenance in the future.



Step 5 For underfloor heating with clipped pipes.

Please skip this step if you are using a Tray System. 

All pipes to be clipped securely, piercing the insulation. The clips are self-sealing, so will not leak when EasyFlow liquid floor screed is poured. Water systems should be filled prior to the application of EasyFlow liquid floor screed.  The purpose of this is to reduce the risk of the pipes floating when the screed is poured.



Step 6 For underfloor heating with a tray system.

Please go back to Step 5 if you are using a clipped pipe system. Plumbers merchants will usually supply a polystyrene-backed cardboard expansion strip with the trays. It is recommended that polythene separating membrane is still used using this method of installation to ensure that a proper tanking of the area is provided.

As discussed, once your underfloor heating system is installed – you are able to enjoy even heating at the touch of a button on your thermostat. Underfloor heating is a much more effective alternative to traditional heating due to even heat distribution.
