At 5°C static temperature or at 5°C and rising, the application may proceed. High temperature working At ambient temperatures above 35°C, the material should not be used as this may cause premature setting. Curing SewperCoat® Dry Spray is a cement-based repair mortar. In common with all cementitious materials, SewperCoat® Dry Spray must be cured immediately after finishing in accordance with good concrete practice. The use of Concure A99, sprayed on to the surface of the finished SewperCoat® Dry Spray 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. In fast drying conditions, supplementary curing with polythene sheeting taped down at the edges must be used. In cold conditions, the finished repair must be protected from freezing. Estimating Supply SewperCoat® Dry Spray is supplied in 20KG Bag. Coverage and yield Approx 2.4 Tonnes per m³ (Approx 8.3L/20KG bag) Limitations SewperCoat® Dry Spray is a protective mortar lining system, care should be taken when considering for use in structural applications. Please contact Parchem Construction Supplies for further information. Do not mix part bags. The product should not be exposed to moving water during application. Exposure to heavy rainfall prior to the final set may result in surface scour. If any doubts arise concerning temperature or substrate conditions, consult your local Parchem sales office. The degree of rebound with any spray applied cementitious product is heavily influenced by the skill and experience of the spray nozzle operator. Overhead applications will produce higher rebound results. Storage As with all hydraulic binders, SewperCoat® Dry Spray must be stored in dry conditions, off the ground. In this case, it will retain its properties for at least 6 months. In many instances, experience has demonstrated that properties are retained for more than one year. SewperCoat® Dry Spray
