Description

Ronafix Prepacked Underfloor Heating Screed 40mm Plus

Ronafix Prepacked Underfloor Heating Screed 40mm Plus. Ronafix Prepacked Underfloor Heating Screed is a pre-packed, ready-to-use mortar for laying floor screeds on underfloor heating systems. It includes a bag of dry components and a bottle of polymer gauging liquid.

• Conforms to BS EN 13813
• For use with underfloor heating systems
• Due to its high early strength and quick drying properties, earlier commissioning of heating systems can be achieved.
• 40mm minimum thickness with 16mm diameter heating pipes
• Requires only 20mm cover over heating pipes
• Ready for foot traffic after 24 hours
• Floor coverings such as vinyl, tiles and carpet after 10 days @ 50mm thick
• Excellent resistance to the passage of water and water vapour

Mixing Advice

Ronafix Pre-packed Underfloor Heating Screed should always be mixed by a forced-action mixer such as a Baron or CreteAngle mixer. Free-fall mixers must not be used. Mix for approximately 3 minutes. Overmixing will entrain air, which may reduce performance.

Placing

As soon as the mortar is mixed, without delay, it should be placed onto the substrate, compacted, ruled, and closed with a float or trowel without delay. Avoid overworking the surface; this will increase the mortar’s tackiness. Wash the float regularly to prevent the buildup of polymer/cement paste.

Apply Thinner screeds in two layers, wet or wet, to aid compaction.

The layers should be approximately equal in thickness.

The base layer should be raked after compaction.

To ensure satisfactory adhesion

Accordingly, if an intermediate layer begins to harden, it is essential to realise that the lower area must be realised to provide a key for the next layer.
