Self levelling screed
Self levelling screed, also known as flow screed or liquid floor screed, is a type of floor screeding material that offers several advantages over traditional sand and cement screed. It is a cementitious or anhydrite-based product that is mixed with water and poured onto a surface, where it self-levels to create a smooth and level finish. Liquid flooring screed is commonly used in construction and building projects, particularly for underfloor heating systems and as a base for various types of flooring.
Here are some key characteristics and advantages of liquid flooring screed:
Self-Leveling: As the name suggests, liquid flooring screed is self-leveling. This means it can spread out and settle into a smooth, level surface without the need for extensive manual leveling. This results in a highly uniform and flat base, making it ideal for various types of flooring.
Rapid Installation: Liquid screed can be installed more quickly than traditional screed, saving time and labor costs. It can be poured and leveled by a skilled installer, significantly reducing installation time.
Thinner Application: Liquid screed can be applied in thinner layers compared to traditional screed, which means it is lighter and requires less material. This can be advantageous in terms of load-bearing capacity and weight considerations in construction.
Enhanced Heat Conductivity: Liquid flooring screed is often used in conjunction with underfloor heating systems. Its self-leveling properties ensure that the heating pipes or cables are fully encased and in close contact with the screed, maximizing heat transfer efficiency.
Reduced Risk of Cracking: The smooth and level surface created by liquid screed reduces the risk of cracking in the final floor finish, such as tiles or vinyl. This results in a more durable and aesthetically pleasing floor.
Minimized Disruption: The speed of installation and self-leveling nature of liquid screed can help minimize construction and renovation disruption, making it suitable for various projects.
There are two common types of liquid flooring screed:
Cement-Based Liquid Screed: This type of liquid screed is made from a cementitious mixture. It is suitable for most flooring applications and is often used with underfloor heating systems.
Anhydrite-Based Liquid Screed: Anhydrite screed is a type of liquid screed that uses calcium sulfate as a binder. It is known for its smooth finish and is a good conductor of heat, making it a popular choice for underfloor heating systems.The choice between cement-based and anhydrite-based liquid screed depends on factors like project requirements, floor finish, and local regulations.Liquid flooring screed is a versatile and efficient solution for creating a smooth, level, and thermally efficient base for various flooring applications. It has gained popularity in the construction industry due to its many advantages and time-saving properties.The choice between cement-based and anhydrite-based liquid screed depends on factors like project requirements, floor finish, and local regulations.Liquid flooring screed is a versatile and efficient solution for creating a smooth, level, and thermally efficient base for various flooring applications.
