Renderoc ST 05 is a polymer modified cementitious material for application to concrete, masonry, brick/blockwork and mild steel. Renderoc ST 05 can be applied to floors, walls and ceilings, both indoors and outdoors.
It can be used as a thin-section repair mortar for discrete patch repairs, for filling of blowholes and other imperfections and as a reprofiling mortar / fairing coat over large areas. After curing the material can either be left as a self-finish or overcoated. Renderoc ST 05 acts as a chloride and carbonation barrier, it can therefore be used to increase or restore effective cover to steel reinforcement at substantially lower application thickness than normal concrete.
As a moisture barrier it provides both active and passive water pressure resistance as well as resistance to aggressive ground water, certain chemicals and mild acids. Typical applications include basement wall lining, construction joint over-banding, swimming pools (prior to application of tiles), marine structures and potable water tanks. (See Limitations)
Renderoc ST 05 provides excellent wear resistance, it can therefore be used in areas subject to traffic such as balconies and walkways.
Renderoc ST 05 can be applied to properly prepared steelwork as a barrier coating. Typical applications include onto cut ends of reinforcement bars in core holes and service penetrations, as well as where protection and repair to concrete encased steel beams and girders are required (in conjunction with a thick section Renderoc repair mortar).
Renderoc ST 05 is suitable for repair methods:
1.3, 2.2, 5.1, 6.1 and 8.2 as defined by BS EN 1504-2:3.1, 7.1 and 7.2 as defined by BS EN 1504-3
WRAS approved when cured for 21 days at 7oC.
