What is Floor Screeding?

Floor screeding is when a well-blended mix of cement and graded aggregates, plus water all come together, to act as a floor base. It can be a sturdy subfloor that is capable of taking on a final floor finish and also be a final wearing surface.

Floor screeding is an important step in flooring and can greatly affect the quality and finish of the flooring, as well as its durability. There are many points to understand about the process, so let’s explore the 3 types of screed:

3 Main Types of Screed 

Bonded Screed

This screed is bonded onto the substrate by slurring bonding to the concrete substrate. Bonded screed is ideal for thinner applications where heavy loading is expected.

Unbonded screed

Unbonded screeds are not bonded directly to a base but instead applied to polythene or a damp proof membrane that is laid on top of the concrete base.  

Floating Screed

Floating screed is usually laid on a layer of insulation with a membrane over it to separate the insulation from the screed. Due to the general aim to gain an A1 rating in modern dwellings, the use of insulation in a floor build-up is becoming a normal practice, which is why floating screed is popular right now.

Types of Cement

To create the screed mix, different types of cement are used. A cement service can supply the required amounts of any of the types of cement you require for your project.

Ready Mix Screeds

A good choice that works for sites where there is limited space for the storage of multiple materials. It can, however, be hard to get the screed out on time where heavy traffic is an issue.

Traditional Screed

This is the standard mix of cement and is used for creating a defined layer for installing a final floor finish. For example for wood, linoleum, and vinyl areas.

Free Flowing Screeds

This screed type has the big advantage of easy placement and provides reliable results. However, if an area is likely to become wet, this is not an ideal solution.

Floor Leveling Compounds

This is generally a more expensive type of screed. It would usually be used for warehouses and other areas that require a very high level of surface regularity or flatness.

Structural Screeds

This type of screed is suitable for installation on precast floor surfaces. Remember, it’s crucial to seek accurate specifications and calculations from a structural engineer before the installation goes ahead.

Fast Drying Floor Screeds/Accelerated Screeds

This is a fast-drying screed alternative. Installation of a final floor finish can take place as early as 3 days after the application of this screeding type making it ideal for projects on a strict time limit.
