Liquid Floor Screed

What is Floor Screeding?

Screed is a thin layer of solid material that smooths over a solid subfloor, like concrete. This is done to help even out a pitted or uneven floor and provide a better surface to walk or build upon.

Liquid screed is designed to provide a smooth, level surface prior to the application of floor finishes. It’s ideal for both commercial and domestic buildings and can be bonded to the subfloor, unbonded with damp proofing, or floating over floor insulation and heating pipes.

Traditional vs Liquid

Traditional solid screeds use cement that is compacted and levelled, but liquid screeds are pumped over the area. These are more preferable, as a self compacting and self levelling screed is quick to pour and smooth to a perfect finish, producing a level surface in a fraction of the time.

As liquid floor screed is installed using a pump, access to the property can be a concern you have. But this is not a problem for EasyFlow. We can pump screeds from around 100 metres away from the property.

Ideal for Water Based Underfloor Heating

Liquid screed is an ideal partner for water underfloor heating, as the screed flows around the pipes, forming a void-free finish. This means greater conductivity – allowing the heat to diffuse evenly into the floor.

If you're looking for a liquid screed to perfectly compliment your water underfloor heating system, then an anhydrite liquid screed is the place to start. As a thermal mass for underfloor heating, Easyflow can provide an ultra-efficient liquid screed that will give up to a 30% increase of the thermal emission value. We have various other options available to give extra strength for shallower applications or to offer guaranteed improved thermal performance.

Types of Liquid Screed

There are two main types, cement-based (flowing concrete) and anhydrite (calcium sulphate). Anhydrite flowing screeds from suppliers like Gyvlon are a blend of a binder, special additives, and aggregates. These mix with water to produce a self levelling screed, perfect for water underfloor heating solutions.

If time constraints are the biggest concern on your build, then fast drying, cement-based liquid floor screeds excel in this area. These fully dry out in roughly half the time of other screeds, without sacrificing durability or longevity.

When dealing with floor depths in excess of 75mm, or for structural floors, cement-based self levelling screeds will be perfect for the job. These can be laser levelled for a precise floor finish and eliminate the need to power float the concrete, dependent on project specification.
