M10 CEMENT BASED LEVELLING/ WEARING SCREEDS

110 BONDED CEMENT:SAND LEVELLING SCREEDS:

CEMEX Readymix - Readyscreed Original

A ready to use, high performance, retarded screeding mortar, it is suitable for all conventional screed applications:

Monolithic - 12 to 15mm thick
Bonded - 25mm minimum, design thickness 40mm
Unbonded construction - 50mm minimum, design thickness 70mm
Floating screed - 65mm minimum, design thickness 90mm for domestic applications
75mm minimum, design thickness 110mm for commercial applications

The surface preparation is similar to traditional floor screeds, requiring a structurally sound surface, free from dust, laitence, dirt and contaminants such as oil and grease. For bonded construction, a bonding coat of cement/water or cement polymer should be brushed onto the base and the screed applied when the bonding coat is wet.

Consult CEMEX UK technical literature for details. CEMEX Readymix can also provide a technical and advisory service and it is recommended that they be consulted early in the design process, for more information contact us on 0800 667 827.
