Take care not to entrain air.

DURAFLOR SL 2 should not be applied onto surfaces known to suffer from rising damp conditions or having a relative humidity of greater than 75% as measure in accordance with BS 8203 Appendix A or by a Vaisala thermo hygrometer type HMI 31. If such an occurrence should happen it is recommended to apply DURAFLOR NWB 21 as a moisture barrier. Further information available upon request. If movement or cracking of the substrate takes place after application then reflective cracking of the topping may occur. All know expansion joints should be maintained in the topping.

DURAFLOR SL 2 should not be applied to the following substrate: Asphalt, unmodified sand cement screeds, PVC tiles or tiles.

DURAFLOR SL 2 should not be applied at material or floor temperature s below 10ºC. Temperature should not fall below 5ºC in the 24 hrs after application.

Concrete slabs exposed to low temperatures act as a heat sink. Heating with hot air gas blowers for 24 hrs can take the air temperature from 4ºC to 20ºC but the concrete slab may only be raised up to 6ºC.

All moving joints must be carried through the DURAFLOR SL 2 and properl y sealed. Construction joints and cracks may be covered but if substrate movement occurs, the DURAFLOR SL 2 will reflect the cracks.
