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 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 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.
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.
This type of screed is suitable for installation on precast
floor surfaces. Remember, itâs 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.
