Topflow Screed C

Designed to provide a smooth level surface in both commercial and domestic buildings prior to the application of floor finishes, It can be unbonded or floating. Also suitable for use with underfloor heating.

Features and benefits:

• It is a more conductive medium than sand cement screed and is self-curing and self-compacting.
• It can be laid thinner than competing sand cement systems without detriment to its performance, so any underfloor heating pipes are closer to the surface (nominal cover to pipes 30 mm).
• No need for force drying as the product is ready to receive floor coverings within 14–21 days dependent on environment.
• It can be laid as a floating construction over most types of rigid insulation board or acoustic matting at a minimum thickness of 40 mm.
• It offers significant programme benefits, as areas of up to 120 m² can easily be installed and finished per hour.
• It's very low shrinkage values mean you require less construction joints than cement based screeds.
• The screed can receive foot traffic 48 hours after placement.
• The product can remain fluid for two hours.
