Features & Benefits


  • Supplied as aready to use blend of dry powders which is formulated for application using the dry spray process
  • Based on Portland cements, graded aggregates, silica fume, chemical additives and polymer modifiers, providing a spray mortar with low rebound and good handling characteristics
  • Low water requirement ensures good strength gain and long term durability
  • Low rebound
  • Can be applied at 3°C and above
  • Rapid early strength gain
  • High resistance to carbon dioxide
  • Excellent bond to concrete
  • Available in 25KG bags
  • Single application up to 200mm vertically and 140mm overhead can be achieved. Thicker sections can be applied in multiple layers



Application Notes


  • Extra protection to the reinforcing steel can be achieved by application of one full coat of Nitoprime Zincrich Plus prior to application
  • Exposed steel reinforcing bars should be firmly secured to avoid movement during the application process as this will affect mortar compaction, build and bond. Additional reinforcement can be fixed using a suitable Lokfix product
  • The product should be emptied from the bags directly into the hopper of the dry spray process machine
  • Wooden, steel or plastic floats, or damp sponges may be used to achieve the desired surface texture
  • Should not be applied at an air / substrate temperature of 3°C and falling. At a static 3°C, or 3°C and rising, application may proceed
  • At ambient temperatures above 35°C, the material should be stored in the shade
  • In common with all cementitious materials, Renderoc DSR must be cured immediately after finishing in accordance with good concrete practice, i.e. using Concure WB, Fosroc Cure B, wet hessian or polythene. 
  • If the finished surface is to be overcoated then Nitobond AR should be used in lieu of Concure WB and Cure B
  • Renderoc DS should be removed from tools, equipment and mixers with clean water immediately after use. Cured material can only be removed mechanically
  • Approx. 12.5 litres / 25 kg bag (approx. 80 bags/m³)

Note: The actual yield per bag will depend on the water addition during application. The coverage figures are theoretical — due to wastage factors and the variety and nature of possible substrates, practical coverage figures will be reduced.



Limitations


  • Should not be used when the temperature is 3°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
  • Non-flammable
