Supaflo TS-20

• The screed is designed to be installed as either a bonded or unbonded screed.
• Refurbishment of uneven floors.
• Remediation or correction of out of level concrete slabs.
• As a levelling screed over floors with restricted ceiling heights.
• Overlay for poorly installed/ levelled screeds.
• As an alternative to light weight screeds, where loading is restricted.
• As an overlay to an electric underfloor heating system.
• Can be installed to a minimum thickness of 20 mm which improves drying times compared to traditional screeds and enables the finished flooring to be installed sooner.
• Suitable for projects where available height and or permitted loading are extremely restricted.

For bonded applications the subfloor should be appropriately treated, this may include mechanical abrasion e.g. Shot blasting, and the complete removal of arising detritus (preferably using a vacuum cleaner) and the application of an organic polymer bonding agent (epoxy resin or polymer dispersion) prior to installation.

For unbounded applications Supaflo TS-20 should be installed on unfolded polythene sheeting of ideally 500 gauge (approximately 110 μm thick). Thick folded sheeting has the potential to induce cracks in the screed.

Supaflo TS-20 should only be used if the building envelope is complete; doors and windows should be in place and must be closed for the first 24 to 48 hours after installation.

The manufacturer recommends bay sizes should be restricted to 750 m² for areas of approximately equal dimension. For long thin sections the maximum manufacturer recommended aspect ratio is 1:5.
