Planitop Smooth & Repair R4is a structural R4-class, rapid-setting, shrinkage-compensated, thixotropic, fibre-reinforced cementitious mortar for structural repairs and smoothing over internal and external horizontal and vertical concrete surfaces; suitable for repairing structures exposed to the open air and in contact with water. It can be applied in a single layer from 3 to 40 mm thick.
Characteristics
Impermeable to water
Hardens without shrinking
High resistance to carbonation
Thermally compatible with freeze/thaw cycles
Good workability
Very low emission level of volatile organic compounds (VOC)
Excellent adhesion to concrete
High dimensional stability to reduce the risk of crazing and cracking
Where to use
Structural repairs and smoothing over internal and external, horizontal and vertical concrete surfaces; suitable for repairing structures exposed to the open air and in permanent contact with water.
Quick repairs to deteriorated parts in concrete on beams, pillars and structural members where the use of high-strength (R4-class) mortar is specified. It may also be used to repair non-structural members such as buffer walls, cornices and the front edges of balconies as long as the base concrete is in good condition.
Quickly smoothing over surface defects in cast concrete, such as deep gravel clusters, spacer holes, construction joints, etc., before painting the surface.
Repairs and structural strengthening of concrete by integrating with mortar.
Repairs to prefabricated concrete members and elements.
Repairs to concrete damaged by rusty rebar due to carbonation and/or chloride penetration.
