When it comes to constructing or renovating a building, one essential aspect that often goes unnoticed is the choice of flooring material. A smooth and level floor is crucial for both residential and commercial spaces. In recent years, liquid floor screed has emerged as a popular choice due to its numerous advantages and ease of installation. In this article, we will explore the world of liquid floor screed, its benefits, installation process, and much more.
Liquid screeds or floor screed, also known as flow screed or flowing screeds or self-leveling screed, is a unique flooring material made of a mixture of high-quality cement, sand, and water, with added polymers to enhance its flow properties. Unlike traditional floor screeds, liquid screeds or floor screed is self-leveling, allowing it to flow and settle evenly across the surface, ensuring a smooth and flawless finish.
Liquid floor screed offers a myriad of benefits that make it an attractive choice for modern construction projects. Some of its key advantages include:
Liquid floor screed can be quickly poured and leveled by skilled professionals, significantly reducing installation time compared to traditional methods.
Due to its high-quality composition, liquid floor screed offers excellent strength and durability, making it suitable for heavy traffic areas.
The composition of liquid floor screed allows it to be an excellent conductor of heat, making it an ideal choice for underfloor heating systems.
The self-leveling, floating nature of liquid floor screed ensures a smooth, seamless surface with minimal joints, reducing the risk of cracks and other damages.
The installation and drying process of liquid floor screed involves several steps to ensure the floor finishes a flawless finish. Here’s a step-by-step guide:
The surface should be thoroughly cleaned and free from any debris or dust. Proper preparation ensures better adhesion and longevity of the sand screed.
The liquid floor screed is poured evenly across the precise floor covering the surface and self-levels to the floor finishes create a smooth and level finish.
The drying time of liquid floor screed is relatively shorter than the drying times of traditional liquid floor screeds, allowing for faster construction progress.
Choosing the right liquid floor screed is crucial for a successful flooring project. Consider the following factors:
Check the composition of the screed, ensuring it meets the required standards and includes necessary additives for better performance.
Opt for a liquid floor screed from a reputable manufacturer known for producing high-quality products.
If you plan to install underfloor heating, ensure the screed is compatible with the system.
Despite its popularity, several misconceptions surround liquid floor screed. Let’s debunk some of the common liquid screed myths:
Contrary to belief, liquid floor screed is an excellent choice for underfloor heating systems due to its superior thermal conductivity.
Liquid floor screed is actually easier and quicker to install compared to traditional liquid floor screeds, making it a convenient choice.

To ensure the longevity of liquid floor screed, follow these maintenance tips:
Sweep or vacuum the floor regularly to remove dirt and debris that may cause scratches.
Use mild cleaning agents to avoid damaging the screed’s surface.
Yes, liquid floor screed is an ideal choice for underfloor heating systems due to its efficient heat-conducting properties and even distribution under floor heating well.
Liquid floor screed is gaining popularity in commercial spaces due to its rapid installation and durability. It is suitable for the floors of various establishments such as hospitals, offices, and schools.
When choosing a reliable brand for liquid floor screed, consider these top options:
Known for its high-performance liquid concrete floor screed suitable for residential and commercial applications.
Offers a premium range of liquid floor screed with excellent thermal conductivity.
A: Yes, liquid floor screed offers numerous advantages over traditional screed methods, including faster installation and improved durability.
A: It is recommended to hire a professional for the best results, as proper installation is crucial for the screed’s performance.
A: The drying time varies depending on factors like thickness and environmental conditions but typically the drying process ranges from 24 to 48 hours.
A: While liquid floor screed is primarily used indoors, certain weather-resistant variants can be used for outdoor applications.
A: Liquid floor screed is generally considered eco-friendly, as it reduces waste and is energy-efficient.
Liquid screed, also known as anhydrite screed, uses a binding agent called calcium sulfate instead of cement. Once water has been added, a reaction occurs, which creates gypsum until the calcium sulfate substrate has been depleted. This makes for a highly durable, self-leveling subfloor, compatible with all floor types. This form of screed offers a low environmental impact and a range of benefits over traditional screeds. They are pumped, free ﬂowing and can be installed in bays of up to 1000m2 before any expansion joints to reduce movement are required. They hold twice the thermal conductivity of traditional screeds, making them ideal for underﬂoor heating applications.
Anhydrite liquid screed is a specialized type of self-leveling flooring material made from anhydrite binder, fine aggregates, and water. Unlike traditional cement-based liquid screeds, anhydrite screed does not contain cement but rather utilizes anhydrous calcium sulfate as the binder. This gives it several distinct properties that set it apart from conventional screeds.
Choosing anhydrite liquid screed for your flooring project offers a range of benefits that make it a superior choice:
Anhydrite liquid screed can be quickly and easily poured, spread, and leveled by skilled professionals, reducing installation time compared to cement-based screeds.
Due to its unique composition, anhydrite screed levels itself without the need for excessive manual intervention, ensuring a smooth and even surface.
Anhydrite liquid screed is an excellent conductor of heat, making it ideal for underfloor heating systems, which will efficiently distribute warmth throughout the depths of the space.
Thanks to its low shrinkage properties, anhydrite screed significantly minimizes the risk of cracks and other damages, providing a durable and long-lasting flooring solution.
The variety of screed you use will depend on the type of concrete base, your expectations for the surface, and the standard of your foundations
There are three standard categories of screed available on the market: bonded, unbonded and floating screed flows all of which can be applied through both liquid and traditional screed methods.
Bonded: This is directly connected to the concrete and voids subfloor (substrate) with an adhesive. The surface of the concrete must be roughened, and a bonding agent thoroughly applied for application to be successful. This thinner application typically lies between 25-40mm
Unbonded: Laid on a PVC/damp-proof membrane, separating it from the concrete substrate makes this surface an excellent choice in buildings where dampness presents a severe problem. This type of screed is ideal for thicknesses exceeding 50mm.
Floating screed: These unbonded surfaces are often used to reinforce an acoustic or thermal layer. In order to remain effective and long-lasting floating screed requires a minimum thickness of 65mm.
Liquid floor screed has revolutionized the world of flooring with its self-leveling properties, rapid installation, and durability. Whether for residential or commercial spaces, this modern flooring solution provides a seamless and smooth finish that enhances the aesthetics and functionality of any building. Consider liquid floor screed for your next flooring project, and experience the benefits firsthand.
