Liquid Floor Screed Vs Sand And Cement

Liquid floor screed is being specified more and more both for new builds and renovations. Traditionally, a sand and cement screed in Shropshire has been used to level a floor surface so that the final flooring can be laid. It has to be said that sand and cement screed is still used quite extensively, but it is rapidly being overtaken by liquid screed. It is estimated that today between 20% and 25% of all screeds laid are now liquid screeds.

Liquid screed has several advantages over sand and cement screed, not the least of which is the speed of laying. Sand and cement screed has to be laid and levelled by a labourer by hand and this is painstaking work. It is also often mixed on site in a cement mixer and this can lead to variations in the consistency of the screed, although on larger sites the screed is now being delivered ready mixed, more often than not.

A liquid screed on the other hand is delivered to site ready mixed and is simply pumped into position by a pump. This is far faster than laying sand and cement screed, and contractors such as ourselves can lay as much as 2,000 square metres in a single day. In fact, it is reckoned that we can lay screed at around 20 times faster than sand and cement.

The Benefits of Anhydrite Screeds

Liquid Anhydrite screed has become incredibly popular today. This flooring option offers many benefits on top of the general benefits that come with using screed to offer a consistent and smooth floor finishing.

Price

While pumped Anhydrite Screed (liquid calcium sulphate) is slightly more expensive than other options, such as sand and cement screed, the margin is not that considerable when considering the benefits that are achieved. Additionally, you can also make savings on the labour and installation cost because the process of pouring out the mixture is far quicker with faster drying times.

Underfloor heating

Are you looking for underfloor heating Peterborough solutions? With underfloor heating you typically need 30mm cover above UFH pipes. Anhydrite screed is effective at creating floor measurements of this depth and offers superior heat distribution and energy regulation compared to many other screed options.

Easily installed

Pumped liquid screeds – due to their consistency – are effectively self-levelling. This means that even though you must hire experts who are experienced with handling this material, the effect will almost always be perfect, with surface smoothness consistent across the entire floor area.

How to Prepare Your Floor for Liquid Screed

One of the main reasons screeds are used today is that they are incredibly effective at levelling a floor surface so that it is completely smooth and achieving a certain finish. Screeds are also a perfect partner for underfloor heating systems, allowing heat to be evenly regulated and distributed.

If you are thinking about commissioning your own floor screed installation as part of your home renovation or commercial property build, you’ll need to consider how the floor is prepared so that the desired effect is achieved. Here’s what you need to know about preparing your floor for liquid screed.

Preparing the Floor

With liquid screeds of all types, it’s essential that the floor is prepared correctly so that the desired effect is achieved and there are no inconsistencies that could lead to cracking later.

The floor will typically consist of thick layers of insulation that the screed will lay on top of and its crucial that this whole structure is stable and strong before any screeding work is carried out. If any of the insulation boards are wobbly or uneven, this can massively impact the surface of your eventual floor and potentially the structural integrity of any kitchen fittings.
