What depth and when to pour?

Deciding screed thickness

With underfloor heating
We recommend pouring between 35mm and 50mm of Easy Screed. This depth includes the diameter of the pipe. Deciding the final thickness will be defined by a number of factors including the size and diameter of the underfloor heating pipe, how the pipe will be installed (clipping or track system) and the choice of insulation. Our minimum requirement is 20mm coverage over the highest point. Please discuss your plans further with our team.

As a finishing screed with no underfloor heating
We suggest that you install a 35mm screed, if there is no underfloor heating being installed. From a strength point of view there is no need to install any deeper. 35mm of Easy Screed can be installed over up to 200mm of insulation.

As a levelling screed
Easy Screed can be poured from 5mm at the lowest point as a levelling screed. A site inspection is required prior to installation of the levelling screed, to determine the type of preparation the sub-floor requires.

Below is a reference list of the most common screed applications

Ground Floor	New Build	Concrete	Up to 250mm	Combination of white polystyrene & high density insulation	Yes Clipped into insulation	35 – 50mm	Ground Floor Standard / Ground Floor A-Rated
Ground Floor	Retro-fit	Concrete	10mm	Triso-Sols or similar	Yes Cable-tied to A142 Mesh	35mm	Ground Floor Triso Insulation
First Floor	New Build	Joist & Ply	8mm	Ethafaom Soundproofing Mat	Yes	35mm	First Floor Ethafoam Sound Proofing
First Floor	New Build	Joist & Ply	10mm	Enkasonic Acoustic Mat	Yes Cable-tied to A142 Mesh	35mm	First Floor Enkasonic Soundproofing
First Floor	New Build	Concrete Slab	As required by client	High density Polyurethane Insulation or similar	Yes	35mm – 50mm

When to install?

In all builds, we recommend that Easy Screed is installed once the building is fully sealed and ideally with the internal plastering complete. Because of the simple installation process for Easy Screed, it allows for the full construction of the house before installation of underfloor heating pipes, minimising any potential damage to the heating system.
