Rockmax TOP (OH) is one part lightweight polymer modified fiber reinforced cementitious repair mortar. The material is suitable to use with vertical and overhead repair areas. Its provide high strength concrete with and include high bonding strength to the existing substrate.
AREA OF USES
Rockmax TOP (OH) is designed for repair damaged concrete for both vertical and overhead applications.
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.
Mixer must use low speed drill mixer (500 rpm) with and including good quality steel paddle. Make sure all tools and equipments are in good conditions and clean. Measure 5.25litre for 25kg bag of Rockmax TOP (OH) . Add material slowly into water while mixing. Mix continuous for approximate 3 minute until homogeneous. Adjust water if the mortar is not workability.
For overhead application, Use steel trowel patch repair mortar to prepared substrate. Working wet on wet with bonding agent (epoxy bonding agent is required). Apply only 10-15mm per layer. Build up next layer if required. Finishing by steel trowel on top of surface. Do not mix with Portland cement.
