Features & Benefits

• Supplied as a ready to use blend of dry powders which requires only the site addition of clean water to produce a highly consistent repair mortar
• Based on Portland cements, graded aggregates, and chemical additives providing a mortar with good handling characteristics while minimising water demand
• Low water requirement ensures good strength gain and long-term durability
• Alkaline in nature and will protect embedded steel reinforcement
• Long open time - applicable to large bay areas
• High strength, abrasion and weather resistance
• One component, pre-bagged to overcome site-batched variations
• Excellent bond to the concrete substrate
• Shrinkage compensated
• Contains no chloride admixtures
• Designed for horizontal use

Application Notes

• To prime reinforcing steel, apply one full coat of Nitoprime Zincrich Plus and allow to dry before continuing
• Prime concrete using Nitobond EP, scrubbed into the surface with a suitable stiff nylon-type brush
• A forced-action mixer is essential. Mixing in a suitably sized drum using an approved Renderoc Mixing Paddle (MR4) with a slow speed (400/500 rpm) heavy-duty drill is acceptable for the occasional one-bag mix
• While the Nitobond EP is still tacky, apply the mixed Paveroc evenly by trowel and tamp in place with a wood float
• May be applied at thicknesses 12mm - 100mm. Thicker sections can be built up in layers
• In cold conditions down to 5°C, the use of warm mixing water (up to 30°C) is advisable to accelerate strength development. At ambient temperatures above 35°C, the material should be stored in the shade and cool water used for mixing
• In common with all cementitious materials, it must be cured immediately after finishing in accordance with good concrete practice. The use of Concure WB, sprayed on to the surface of the finished mortar in a continuous film, is recommended
• Nitoflor FC products may be applied over the repair area after prior removal of the curing membrane generally after 3 days
• Paveroc should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically
• Coverage and yield: Approximately 11.5 litres / 25 kg bag (approximately 0.9 m² at 12 mm thickness)

Limitations

• Where a rapid return to service is required when patching small areas (>4m2 ) of concrete pavements and floors, the use of Patchroc GP is suggested instead of Paveroc
• Should not be used when the temperature is below 5°C and falling
• Should not be exposed to moving water during application. Exposure to heavy rainfall prior to the final set may result in surface scour
• Free-fall mixers must not be used. Mixing of part bags should never be attempted
• As with other ‘one pack’ repair mortars, the product may exhibit satisfactory handling characteristics even though inadequately mixed. This will result in a significantly lower level of performance or possible failure. It is therefore essential that mixing instructions are strictly adhered to with particular emphasis on the quantity of water used and the time of the mixing operation
