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
