Heated Floor Screed for Healthcare & Care Homes
Application is extremely fast – applied at 500m² per day and walk on in 6 hours – no delays for follow-on trades
Südanit 280 Alpha Hemihydrate Screed’s advanced composition means that it reacts quickly with water, providing consistent, reliable drying characteristics and considerably faster drying times, enabling follow-on trades to proceed without delay. This has the advantage of ensuring your project completes in a timely manner, offering your architect or designer flexibility. For your builder/contractor and floor covering specialist, it offers ease of installation on site.
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 Anhydrites.
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)
Fast Floor Screed’s flowing 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 should be observed when preparing the floor:
1) INSULATION
Suitable insulation is placed onto a 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.
2) PLASTIC MEMBRANE (P.U. MEMBRANE)
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.
3) UNDERFLOOR HEATING PIPES
Underfloor 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.
4) FLOOR SCREED PLACEMENT
Before screed placement commences, we set adjustable tripod depth gauges set by laser level to 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.
5) FINISHED FLOOR
Smooth and level. Foot traffic can commence in as little as 6-8 hours under normal drying conditions
RESULT – Provides a perfectly flat floor – ready for your floor covering when fully dry.
