Features & Benefits

• Supplied as a ready to use blend of specially selected dry powders, which requires only the addition of drinking quality water to produce a highly consistent repair mortar
• No independent primer required – a slurry coat of Renderoc Patch is sufficient
• Single component – mixed with fresh water
• Low slump
• Easily applied by hand or trowel

Application Notes

• Can be applied overhead from featheredge to 20mm maximum and vertically from featheredge up to 30mm maximum without slump deformation
• Prime with a slurry worked into the saturated surface dry substrate by a gloved hand or trowel, ensuring all voids are filled
• Once the substrate has been primed immediately apply the Renderoc Patch ‘wet on wet’ to the primer
• Mix the material by hand or machine until a stiff / no slump consistency is achieved, ensuring the colour is uniform and all particles are well wetted
• To better match the base concrete, the mortar colour can be altered with Renderoc Patch Lightener/Darkener
• Allow the material to stiffen slightly before reprofiling with a trowel to the required dimensions
• In cold conditions below 10°C, the use of warm water (up to 30°C) is advisable to accelerate strength development. At ambient temperatures above 30°C, the material should be stored in the shade and cool water used for mixing
• In common with all cementitious materials, the product 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
• Should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically
• Yield: 13 litres mixed material per 25KG bag

Precautions

• Only mix enough material to apply within a 20 minute period
• Never add extra water to regain workability once set
• Do not over work the finished surface
• Cool temperatures retard setting times
• Warm temperatures accelerate setting times

Limitations

• Should not be used when the temperature is below 3°C and falling
• Exposure to heavy rainfall prior to the final set may result in surface scour
• Should not be exposed to moving water during application or totally immersed in water for the first 24 hours after application
• For overhead repairs exceeding 20mm depth use one of the Renderoc HB range of products. For larger floor repairs in excess of 0.25m2 use Paveroc or Patchroc GP
