LIQUID SCREED CONTRACTORS

Nationwide Supply & Install

Complete Range of Liquid Floor Screeds for Residential, Commercial & Industrial Projects

Interior Screed Group Ltd provides professional liquid screed supply and installation services throughout the UK, supporting housebuilders, developers, main contractors, commercial construction companies and private clients.

With over 15 years of trading experience and more than one million square metres of floor screeding installed since commencement of trading, Interior Screed has extensive experience across traditional sand and cement screeds, specialist fast-drying screeds and liquid screed systems.

Our liquid screed services cover residential housing developments, apartment blocks, commercial buildings, healthcare facilities, educational premises, retail developments and industrial projects.

We work with a broad range of liquid floor screed specifications, including calcium sulphate liquid screeds, anhydrite flowing screeds, cement-based liquid screeds and specialist flowing screed products.

Our approach is straightforward: specify the correct floor screed for the project, rather than recommending liquid screed where traditional sand and cement would provide a more appropriate solution.

What Is Liquid Screed?

Liquid screed, also known as flowing screed or self-compacting screed, is a pump-applied floor screeding material used to form a screeded surface over suitable substrates, insulation systems and underfloor heating installations.

Liquid screed is generally divided into two principal categories:

  • Calcium Sulphate Liquid Screed: Anhydrite or gypsum-based flowing screed commonly used in residential and commercial floor construction.
  • Cement-Based Liquid Screed: Cementitious flowing screed systems suited to a range of construction applications, including certain moisture-exposed environments where permitted by the product specification.

Liquid screed can offer practical installation benefits on suitable projects, particularly where large floor areas require pump application.

However, liquid screed is not automatically the correct choice for every installation. Drying times, moisture sensitivity, surface preparation, final floor coverings and the overall construction programme must all be considered.

CEMEX Supaflo liquid screed is designed for pump application, providing a flowing screed solution for appropriate bonded, unbonded and floating floor constructions.

The CEMEX liquid screed range can be considered for projects incorporating underfloor heating, new-build housing, apartment developments and commercial floor areas.

As with other calcium sulphate systems, CEMEX liquid screed installations require appropriate consideration of moisture levels, drying conditions, floor-covering requirements and any necessary laitance removal.

Flowcrete Liquid Screed – Isocrete Flowing K

Flowcrete provides specialist screed systems through its established Isocrete product range.

Flowcrete Isocrete Flowing K is a cementitious, self-compacting liquid screed incorporating graded aggregates and proprietary additives.

This Flowcrete liquid screed system is suitable for various bonded, unbonded and floating screed applications, subject to the relevant technical specification.

Flowcrete liquid screed products can be considered where a cementitious flowing screed is required for a particular floor construction, with drying, strength and final floor-finishing requirements assessed during specification.

ANHYDRITEC Liquid Screed – Gyvlon

ANHYDRITEC manufactures Gyvlon, a recognised range of calcium sulphate flowing screeds. ANHYDRITEC Gyvlon liquid screed systems are developed for residential, commercial and specialist flooring applications. The ANHYDRITEC range includes products intended for applications such as underfloor heating, acoustic floor systems, thin-section construction and other specialist installations. When considering ANHYDRITEC liquid screed, the choice of Gyvlon product should reflect the building specification, floor-loading requirements, heating installation and intended floor covering.

LKAB Minerals Liquid Screed – Gypsol

The LKAB Minerals liquid screed range covers general floor construction, underfloor heating, specialist thickness requirements, heavy-duty applications and other construction needs.

When specifying LKAB Minerals Gypsol liquid screed, particular attention should be paid to product-specific drying instructions, surface preparation and floor-covering compatibility.

McGraths Liquid Screed – Cemfloor

McGraths develops and supplies the Cemfloor cement-based liquid screed system.

McGraths Cemfloor liquid screed is a cementitious flowing screed designed for appropriate residential, commercial and specialist floor constructions.

The McGraths Cemfloor range includes products for standard floors, underfloor heating, specialist levelling and fast-track applications.

When specifying McGraths liquid screed products, it is important to consider the relevant Cemfloor technical data sheet, floor construction, moisture requirements and preparation necessary before installing floor coverings.

Important: Liquid Screed Laitance Removal and Surface Preparation

Laitance removal and correct surface preparation are critical considerations when specifying liquid screed, including low-laitance products.

Calcium sulphate liquid screeds can develop surface laitance or a weak surface layer during curing. Where present, laitance must be removed in accordance with the manufacturer’s requirements before subsequent floor finishes are installed.

Products described as low-laitance liquid screed should not automatically be assumed to require no sanding, abrasion or surface preparation.

The surface preparation requirements for every liquid screed installation should be established from the current manufacturer’s technical guidance and the requirements of the flooring system.

Some proprietary liquid screed products are formulated to eliminate laitance and do not require routine sanding for laitance removal. Nevertheless, those surfaces must still be properly inspected, cleaned and prepared for the chosen finish.

Potential additional operations include:

  • Mechanical sanding or abrasion where specified
  • Removal of surface laitance or weak material
  • Removal of dust and construction contamination
  • Surface cleaning and vacuuming
  • Moisture testing before floor coverings
  • Application of suitable primers where necessary
  • Verification of adhesive and flooring compatibility

These additional preparation requirements should be considered when comparing the complete installed cost of liquid screed with traditional sand and cement screed.

Failing to allow for necessary surface preparation can introduce additional labour, dust, programme delays and flooring installation costs.

Liquid Screed for Underfloor Heating

Liquid screed is regularly specified for underfloor heating installations in residential and commercial developments.

The flowing consistency allows liquid screed to surround suitably secured underfloor heating pipework, providing contact between the heating system and the surrounding screed.

Suitable products may include specialist liquid screed systems from Tarmac, CEMEX, ANHYDRITEC, LKAB Minerals, Flowcrete and McGraths.

However, liquid screed is not the only appropriate material for underfloor heating.

Traditional sand and cement screeds, including suitable modified and fast-drying systems, are also widely used in underfloor heating constructions.

Correct performance depends on the complete floor build-up, pipe layout, insulation, screed thickness, installation quality and heating commissioning procedure.

Liquid Screed vs Traditional Sand & Cement Screed

Interior Screed installs both liquid screed and traditional sand and cement screed systems.

Traditional sand and cement remains a highly established, durable and versatile screeding method, suitable for a broad range of residential, commercial and industrial applications.

Liquid screed may be considered where its flowing characteristics, placement method or particular product specification suit the project.

However, traditional sand and cement can offer practical advantages, particularly where the project requires a semi-dry material, falls, specific surface characteristics or a screed system without the laitance-removal considerations associated with flowing screeds.

Our objective is to identify the most suitable floor screed system for each project, not to promote one material at the expense of another.

Frequently Asked Questions About Liquid Screed

Is liquid screed better than traditional sand and cement?

Not necessarily. Liquid screed and traditional sand and cement have different installation characteristics and technical considerations. The correct choice depends on the floor construction, expected loading, drying requirements, floor finishes and site conditions.

Many calcium sulphate liquid screeds require laitance removal or surface sanding. Low-laitance products may still require preparation. Some proprietary cement-based and zero-laitance products do not require routine sanding to remove laitance. Always follow the manufacturer’s technical instructions and the floor-covering specification.

Yes. Many liquid screed systems are suitable for underfloor heating. The required screed thickness, pipe cover, drying period and commissioning procedure depend on the particular product.

Liquid screed drying times vary considerably between products and depend on thickness, temperature, humidity, ventilation and heating conditions. Fast-drying liquid screed systems may offer different programme requirements from standard calcium sulphate screeds.

We can discuss product suitability and local availability for liquid screed systems associated with Tarmac, CEMEX, Flowcrete, ANHYDRITEC, LKAB Minerals and McGraths, including Topflow, Supaflo, Isocrete Flowing K, Gyvlon, Gypsol and Cemfloor.
