Overview
KingRep EPBMS is a three component solvent-free lightweight epoxy mortar, designed principally for use with maximum chemical and abrasion resistance for protection of concrete and other substrate in sewage tanks and manholes. The lightweight graded filler system along with thixotropic additives, allows lining for high build applications particularly in vertical and overhead situations.
When used in conjunction with KingRep Primer EPBM the product provides excellent adhesion to concrete materials. When finished correctly, KingRep EPBMS provides an impermeable layer with good resistance to abrasion, weathering and chemical attack.
KingRep EPBMS has a strength that exceeds normal concrete strength, the cured layer is tough, resilient and gives excellent resurfacing and repair system. KingRep EPBMS is supplied in a grey colour to match existing concrete substrates.
KingRep EPBMS application areas include, lining and benching manholes, sewage tanks, and all similar structures which require impervious mortar or lining to achieve maximum chemical resistance.

Taking care to ensure that the bottom and sides are thoroughly scraped, transfer the entire contents of the hardener container into the RESIN container. Using a mixer attached to a slow speed electric drill, mix for approximately 2 minutes until a uniform consistency is obtained. The resin mixture should then be transferred to a separate container or forced action mixer such as a creteangle type mixer, and the filler gradually added and mixed for a further 2 minutes or until the filler has thoroughly wetted out and a uniform consistency obtained.
How to use
Surface preparation
The surface must be structurally sound, free from oil, grease and other forms of contamination. Concrete should be surface dry and suitably prepared either by scabbling or grit blasting to remove any surface laitance. Steel surfaces should be grit blasted to remove all rust and scale. (Consult the KingKrete Technical Department for further details).
Priming
Substrates should be primed with KingRep Primer EPBM. The primer should be applied so that the surface is thoroughly wet, ensuring there is a continuous film of resin over the surface. The KingRep EPBMS should be applied whilst the primer is still tacky.
Mixing
KingRep EPBMS comprises three components, a resin base, hardener and filler which are supplied preweighed in the correct proportions. Under no circumstances should part mixing be carried out.
Application
The KingRep EPBMS should be applied and well compacted, by steel trowel. The lightweight mortar should be applied in successive layers, each layer being well compacted before each application of subsequent material. If the mortar has been allowed to harden, the surface should be abraded and a further coat of KingRep Primer EPBM applied.
Where necessary, the mortar is shaped to the required profile e.g. to form a cove and trowelled to a smooth finish. This operation will be aided by lightly wiping the trowel with KingKrete solvent.
WORKING TIME
KingRep EPBMS has a working time of approximately 60 minutes at 20°C. Mixed material should not be left standing for any length of time prior to application as this will considerably reduce its working time.
WORKING CONDITIONS
- KingRep EPBMS should not be applied at temperatures below 5°C.
- It is recommended that material temperature is not exceeding 35°C, and substrate temperature is not exceeding 55°C.
Curing
KingRep EPBMS should be allowed to cure for 24 hours at 20°C. At the same temperature, full mechanical and chemical properties are achieved after 7 days (please consult our Technical Department for details of curing times at other temperatures).
Cleaning
Clean uncured material with KingKrete solvent. Cured material can only be removed mechanically.
