Watco Concrex Flex Repair Mortar
CONCREX FLEX REPAIR MORTAR
CONCREX FLEX REPAIR MORTAR
Concrex Flex has been specially developed with a new blend of resins, to enable expansion joints, ramps, guide rail surroundings and any other areas commonly subject to vibration and movement to be repaired.
Areas like these may have been badly affected by cracking and spalling in the past, but Concrex Flex will provide a permanent repair where a rigid mortar might fail.

CURING TIME (HOURS)
Normally 3-6 hours depending on temperature. Curing times will be very slow at temperatures below 50°F.
POT LIFE
30 minutes to one hour, depending on the temperature. If Concrex Flex® is used past its working life, trowelling will become difficult and adhesion will be reduced.
SHELF LIFE
2 years
FLASHPOINT
>200ºF (94ºC)
CONCREX STANDARD
It has all the strength and abrasion resistance associated with Concrex Standard but offers sufficient flexibility to resist cracking due to movement of the substrate.
TEMPERATURE
Watco Concrex Flex cures in 6 hours depending on temperature. Curing time will be extended by low temperatures. Curing will be very slow or even arrested by temperatures at 50°F and below.
HOW TO APPLY
SURFACE PREPARATION
Surfaces should be clean, dry and free of all loose material. Wire brushing or sweeping is generally sufficient. Watco Bio-D degreaser can be used to remove grease and oil.
MIXING AND APPLICATION
Each Watco Concrex Flex® pack contains a granular resinous compound and separate containers of curing agent. The components are mixed by trowel according to the simple instructions in the pack until a smooth grey mortar is obtained.
The more thorough the mixing, the wetter, smoother and more manageable the mix becomes. This can be achieved quite quickly by wearing disposable gloves and kneading the mixture by hand. This is troweled firmly against the surface to be repaired, and finished with a trowel or float. To prevent drag on the trowel, a rag moistened with mineral spirits may be wiped across the face of the tool.
