Introduction
Floor screed is an essential layer in modern construction, providing a smooth and level surface for final flooring finishes. Whether you are renovating a home or working on a large commercial project, floor screed plays a vital role in achieving durability and precision.
What is Floor Screed
A thin layer of material, typically a mix of cement and sand or a liquid alternative, applied over a structural base. Its purpose is to create a flat, smooth surface that supports tiles, wood, vinyl, or carpet. Unlike structural concrete, which carries loads, screed’s role is finishing.
Floor Screed Thickness
The thickness of the screed depends on the project. Standard sand and cement screeds are usually 65–75mm thick, while liquid and flowing screeds can be as thin as 35–40mm, making them ideal for underfloor heating.
Types of Floor Screed
Several screed options are available to suit different applications.
Traditional Sand and Cement Screed
This is the classic choice, durable and reliable. It is hand-applied and takes longer to dry, but remains popular for both residential and commercial projects.
Liquid or Flow Screed
Flow screed, also known as self-levelling or liquid screed, is faster to apply, dries more quickly, and offers excellent surface smoothness. It is widely used with underfloor heating systems due to its thermal conductivity.
Fibre-Reinforced Screed
By adding fibres, this type of screed becomes more resistant to cracking, making it suitable for heavy-use areas.
Gyvlon Screed
A specialist anhydrite screed, Gyvlon provides a flowing consistency and is particularly effective for large-scale projects.
Key Benefits of Floor Screed
Choosing the right screed provides several long-lasting benefits.
Strength and Durability
This screed type ensures the final flooring lasts longer by providing a solid and even base.
Compatibility with Underfloor Heating
Liquid and flow screeds work seamlessly with underfloor heating, maximising energy efficiency.
Smooth Finish
A properly laid screed floor delivers a perfectly level surface, ensuring tiles, timber, or vinyl flooring perform as expected.
Efficiency in Application
Flow screeds can be applied quickly, reducing labour and project timelines.
When to Use Floor Screed
It is suitable for:
-
Residential renovations and new builds
-
Commercial and industrial floors
-
Projects requiring underfloor heating integration
-
Areas needing a polished and durable finish
