Ultraflo® is a unique hemihydrate calcium sulphate liquid floor screed designed to be used with underfloor heating. The product guarantees minimal shrinkage and cracking, improved heat responsiveness with underfloor heating, reduced heat lag delay, reduced energy costs and is eco-friendly.

Due to its hemihydrate formulation, Ultraflo® self-levelling liquid floor screed does not suffer from surface laitance (a scum/dust of material adhering to the top of the screed during the curing process) unlike other liquid floor screeds on the market. This unique advantage means Ultraflo® requires no buffing/grinding to the floor surface prior to the application of floor finishes.

Under good drying conditions of 20°C and 65% relative humidity, Ultraflo® hemihydrate liquid floor screed laid at 40mm will dry in 40 days. It will dry at 1mm per day for first 40mm then 1/2mm per day for each mm of additional depth. For example 50mm screed will dry in 60 days.With the use of under floor heating, a 50mm Ultraflo® hemihydrate liquid floor screed can be force dried in less than a month.

Whether your project is a conversion, renovation, extension or a new self-build, we aim to make the process simple. Right from design to the finished floor. Full Technical and Site Support is available at all stages of the screeding process and RTU provides a Supply and Fit service using only approved layers.

USE WITH ULTRABEAD
RTU supplies and installs Ultrabead, which is used as an alternative, or in conjunction with insulation boards for commercial and domestic applications. We offer the full package of supply, install, insulation and screed.

How Ultrabead Works
Ultrabead is an insulating layer that is installed in situ creating a continuous solid insulating layer with no gaps, leaving a level surface for the finished screed to be applied to.

• No need to store bulky insulation on site Our experienced team complete supply and install
• Poured in situ insulation with no wastage of insulation off cuts
• Continuous insulation layer with no gaps causing cold bridges
• Replaces or used in conjunction with EPS and PIR boards
  

Ultrabead: Perfect with Liquid Floor Screeds
Thin screeds enable a thicker layer of insulation that helps to achieve the required U-values. The delivery of a more consistent screed thickness also provides a more even floor temperature when used with UFH. For more information contact our sales team.

• Not subject to surface laitance (a scum/dust of material adhering to the top of the screed during the curing process.) This unique benefit means Ultraflo® requires no buffing/grinding to the floor surface prior to application of floor finishes unlike other liquid floor screeds.
• Minimal drying shrinkage or curling, meaning substantial reduction of movement joints compared to sand:cement screed.
• Fast heat response times resulting in greater thermal efficiency when used with underfloor heating.
• Speed of installation, up to 2000m2 per day, and is virtually self-levelling.
• Reduced laying depths, weights and drying times (as little as 30mm required).
• Allows light traffic in 24 hours.
• Less labour-intensive installation.
• Economical alternative to traditional sand:cement screed.
• Quality controlled mix for consistency.
• Eco-friendly credentials, being formulated from a by-product of flue gas desulphurisation.
