Liquid Floor Screed 2017-03-06T10:58:04+00:00


Liquid floor screed is a pump applied, synthetic anhydrite. Ideal for sub floor levelling, they provide a smooth, flat surface for the application of all floor finishes. Suitable for most commercial and domestic buildings as a levelling layer, liquid floor screed offers complete versatility of use: with thermal and acoustic insulation, electrical services and under-floor heating systems.



There are many benefits to using a liquid floor screed rather than a traditional floor screed.

Traditional sand and cement screeds can be particularly labour intensive and this service strongly depends on the quality of installation.

Liquid floor screed on the other hand, is perfect for sub floor levelling and are known to provide a smooth, flat surface for the application of all floor coverings. Application is a much quicker process, and dependant on supply, up to to 1000m2 a day can be laid.

Anhydrite screeds will not crack or curl at the day joints unlike traditional screeds. There is minimal shrinkage and cracking with anhydrite liquid floor screed.

Drying Times

The average drying time of anhydrite liquid floor screed is of course dependent on the conditions of the site however; 65mm of screed would take 36 days to dry. A traditional screed on the other hand would take 65 days to try for the same thickness.

There’s no reinforcement with an anhydrite liquid floor screed, whereas traditional floor screeds require steel reinforcement or Polypropylene fibres.

Environmentally Friendly

Anhydrite Screeds leave no waste left behind. Traditional screed pallets must be returned and cement bags/polythene covers have to be disposed of. Anhydrite screed is a very environmentally friendly product.

Anhydrite screeds are far less manually intensive in comparison to traditional cement screeds, resulting in less of a risk of repetitive strain and muscular skeletal injuries for the contractors. Traditional screeds are installed by operatives kneeling down in wet cement, issuing a risk of dermatitis or cement burns.


Traditional screed mixes are usually batched by hand, leading to a poor quality mix and inconsistent quality.

Liquid Floor Screed

Why use a liquid floor screed rather than a traditional screed?

Liquid floor screeds are self-levelling, synthetic anhydrite, which are pump-applied in order to provide a smooth and consistent floor surface. Using anhydrite in the screed as opposed to cement is often preferred, as there are many benefits to anhydrite that completely outweigh traditional screed methods.

Liquid Floor Screed

Why are liquid anhydrite floor screeds more beneficial?

The finished surface of a traditional screed relies heavily on the flooring contractor and can be extremely labour intensive, whereas self-levelling, synthetic anhydrite screeds are known to provide a smooth and flat surface.

Anhydrite screed allows foot traffic (people walking on the floor) within 1 or 2 days with no need to cure. Traditional floor screeds on the other hand won’t allow foot traffic for up to 3 days.

Margden Heating Ltd
Liquid screed is delivered in m3, so basically we have to work out how many cubic metres a customer needs for a job. The calculation for this is : M2 (the size of the area to be covered) x 0.05/0.06 (the depth of the screed to be laid, normally 50mm/60mm or 0.05/0.06 metres)
From a standing position our installers can hand tamp the screed using an up and down motion to consolidate liquid screed. A small fast action ensures any air voids rise up so the slab or base will be stronger and evenly spread.
Our team of installers will ensure the screed is levelled off to an even depth by using a laser level for accuracy.

Under Floor Heating works very well with liquid screed, due to the chemical make up (ie anyhydrite). The heat transmission utilizing liquid screed is far better than sand and cement screed.

Depending on the drying conditions for a property, the floor can be walked upon following a 24/48 hour period. This is project dependent however, as it depends on the individual drying conditions for that property
