Features & Benefits

• Consists of powder and polymer components - a blend of cements, graded aggregates and chemical additives, with a maximum grain sizes of 0.5 mm
• The consistency of the product may be adjusted as required for application by trowel, brush or roller, in thicknesses from 0-5mm in a single layer
• The liquid component, based on modified acrylic polymers, gives a creamy consistency with extremely good application and barrier characteristics
• Exhibits excellent thermal compatibility with concrete and is fully compatible with other Renderoc mortars and Dekguard coatings
• Easy to mix and apply
• Can be applied vertically, horizontally and overhead
• Excellent bond to concrete without priming
• Abrasion resistant, can be subjected to traffic
• Carbonation barrier
• Chloride barrier
• High frost resistance
• High compressive strength
• Please refer to the Product Data Sheet for full details of:
  • Properties

  • Coverage rates / mixing ratios
  • Standards Compliance
  • Storage
  • Health and Safety

Uses

• 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
• 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 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
• Provides excellent wear resistance, it can therefore be used in areas subject to traffic such as balconies and walkways
• 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
• 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, and WRAS approved when cured for 21 days at 7°C

Application Notes

• On floors or walls, small areas greater than 5mm depth should be filled with Renderoc Patch prior to application. On floors, larger areas >12mm depth may also be filled with Patchroc GP
• Under normal circumstances priming is not required. However, very porous substrates may require sealing with Nitobond AR
• Should be mixed in a forced action mixer of adequate capacity. Mixing in a suitable sized drum using an MR3 mixing paddle with a slow speed (500 rpm) heavy-duty drill is acceptable
• Can be applied by brush, roller or trowel depending on consistency and application
• Formulated for application to clean, sound substrates, however application over existing acrylic based coatings or paints may be possible in certain circumstances where filling or smoothing over undulations in the substrate is required before overcoating
• In common with all cementitious materials, it must be cured immediately after finishing in accordance with good concrete practice. The use of Nitobond AR, sprayed on to the surface of the finished mortar in a continuous film, is recommended
• Large areas should be cured as trowelling progresses (0.5 m2 at a time) without waiting for completion of the entire area
• Can be subjected to foot traffic after 12 hours at 20°C
• Formulated for application to clean, sound substrates, however application over existing acrylic based coatings or paints may be possible in certain circumstances where filling or smoothing over undulations in the substrate is required before overcoating
• Dekguard products may be applied over the repair area without prior removal of the Nitobond AR curing membrane. Other curing membranes must be removed prior to the application of Dekguard products
• Should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically
• Supplied in 20kg bags of powder and 5.0 litres of liquid, yielding approximately 12 litres per pack depending on mix ratio - coverage dependant on usage. See the product data sheet for coverage rates

Limitations

• Should not be applied when the substrate and/or air temperature is below 5°C and falling
• Application at high humidity and/or on a falling thermometer may result in a white surface discolouration. This will not affect product performance and should decrease with time
• Potable water tanks are for use on consumer premises only. This product is not DWI listed
• Not suitable for heavily trafficked floors
• Exposure to rainfall prior to the final set may result in water uptake and severe reduction in the performance of the hardened product. Exposure to mist or high humidity prior to sufficient hardening may result in discolouration of the surfaces. These white discolourations will decrease with time
• Should not be applied over elastomeric coatings, epoxy, polyurethane, polyurea, polyaspartic or MMA based coatings, or over any coating subject to traffic. In such circumstances the existing coating should be removed
• When applied over existing coatings or paints, the performance characteristics and bond of  the product may be impaired and its fire rating invalidated
