"Can’t recommend this company any higher! Philip was a dream to deal with, no questions too silly and was always available for us. He made the whole process so simple. We were recommended Philip by a very good family friend, they said they are the best in the business and Philip is the best and they were so right. As a self build things such as floors can be so daunting. Well done Philip and crew, keep up the absolute great work. Will be recommending these guys on to everyone. Thanks"

Thanks a million! Especially to Philip".

Fast Floor Screed lays smoothly and provides a superb perfectly flat floor – ready for your floor covering

Our Alpha Hemihydrate Screed’s easy workability means that it mixes and flows smoothly, with none of the inconsistencies that are inherent in synthetic Anhydrite Screeds. Südanit 280 Alpha Hemihydrate Screed is stable and does not segregate, so there is no surface skin formation as there is with Anhydrite.

It means less finishing and fewer joints

Consistent drying and smooth laying mean no finishing before final floor coverings are laid and there’s no need for additional smoothing compounds.

The perfect Screed for use with Underfloor Heating (UFH)

Alpha Hemihydrate Screed can be installed in a heated floating-floor screed construction, uniquely, with the commissioned underfloor heating system up and running @ 25°C!

Fast Floor Screed’s Alpha Hemihydrate screed is particularly suitable for applications over Under Floor Heating (UFH) and cavity floors.  Südanit 280 Alpha Hemihydrate Screed is a liquid self-compacting, self-flowing, self-levelling Screed which flows to fully encapsulate underfloor pipes or wires and reduces the potential for air bubbles/pockets which can have an adverse effect on heat transfer. 


Floor preparation for Screed application over Under Floor Heating – UFH

The correct preparation is essential to achieve the best performance from your UFH system and the final floor finish.  The following is a demonstration of how the floor should be prepared when Screeding with UFH:
Suitable insulation is placed onto the structural floor along with edge insulation, against the perimeter of the walls and columns.

RESULT – This avoids cold bridging and allows the floating floor to expand.

Before placing the underfloor heating pipes, a plastic membrane is installed directly onto the insulation boards and returned up the walls.

RESULT – This ensures no leakage of the screed and allows the screed to dry consistently throughout.

Under floor heating pipes are placed and fixed to the insulation boards using clips and/or rails. Fixings need to be no more than 500mm apart and extra fixings are required for bends/returns.

RESULT – Ensures pipes do not float during screed application.

Before screed placement commences, we set adjustable tripod depth gauges set by laser level to the agreed datum, which is usually calculated from your door threshold.  There is no requirement for datum lines on walls.

RESULT – A perfectly flat floor evenly throughout the building.

Smooth and level. Foot traffic can commence after 6-8 hours under normal drying conditions.

RESULT – Provides a perfectly flat floor – ready for your floor covering when fully dry.
