AREA OF USES
APPLICATION AND INSTALLATION
Concrete substrate must be clean and free from oil, grease, dust, particles, mould oil, curing compound. Concrete substrate must be at least 28 days old and include compressive strength of 25Mpa. Shape concrete by grinder machine to receive thicken layer (approximate 10mm thick). All edge must be shape until receive smooth and sound concrete substrate. Soak water until concrete saturated. Bonding agent should be applied to increase bonding strength.
