Setting Times
NATCEM 35 is designed to commence setting at 35 minutes and finish setting at 40 mins at 20°c. In winter NATCEM 35 can be used down to 0°c. The set will be slower but can be accelerated by using warm water. In very hot temperatures the set will be faster and can be slowed by using cold water.
Yield
Generally 1 x 25kg bag of NATCEM 35 mixed with 3.6 litres of water will produce 10 litres of finished mortar.
