What is the difference between liquid screed and concrete?


Whilst both concrete and liquid screed do contain some of the same properties, there are tangible differences between them and how they are used.

Concrete is used for a wide range of projects such as the construction of buildings, laying house foundations, path and driveways, flooring (both commercial, residential and industrial) and more. Concrete is a relatively cheap material and is incredibly durable with few maintenance requirements. 

Screed is used as a final layer for flooring, it is laid to prepare the installation of a floor covering such as carpet, timber or tiling. There are typically five distinct types of screed flooring but at Wright MiniMix, we have developed our own version of liquid screed – our Wrightflow Screed. Liquid screed is fast becoming an industry standard in floor screeding. Some people refer to liquid screed as ‘self-levelling screed’ too.

Thanks to our extensive knowledge and experience within the concreting and liquid screed industry, we developed our liquid screed after an in-depth development and vigorous testing process. Our aim was to ensure that it met the specific needs of our customers and to produce a high-quality product.

Our liquid screed is self-compacting and removes the need to have the floor sealed prior to laying. The liquid screed is installed over underfloor heating pipes and insulation and the screed actively conducts the heat evenly across the entire floor surface. One of the main benefits of liquid screed is that it helps retain the heat for longer. Our Wrightflow liquid screed covers the pipework completely and eliminates any potential gaps of air that could prevent the heat from rising. 

It is important to ensure that you allow a sufficient drying time when laying liquid screed, otherwise cracking may occur.

Similarly to concrete, our liquid screed contains blended cement, water, sand, limestone, dust as well as more unique materials such as anti-crack fibres, super plasticiser and an anti-shrink agent.

The installation of liquid screed can be less labour intensive over other screed flooring solutions and by using our own liquid screed can increase the thermal efficiency of your building which will be more efficient both in terms of money and energy consumption too.

Liquid screed doesn’t require the same depth as other mixes of floor screed and this means that you have a significant reduction in both weight and drying time too!

Aesthetically, you can usually tell the difference between concrete and liquid screed by how it looks. Concrete has a rougher texture and liquid screed has more of a smoother finish. Liquid screed is traditionally only used as a finishing layer on internal floors whereas concrete can be used for both internal and external flooring.
