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.

Surface Preparation

Do not use on frozen or over heated substrates (Outside the range of 0°c – 30°c). Prepare the surface in advance to provide an adequate key. On glazed brickwork the joints should be raked out and the surface bush hammered to form a key. The surface to which the NATCEM 35 is applied should be clean, free from dust and thoroughly dampened. Where necessary steel or aluminium mesh can be used. Ensure that a 10 mm minimum thickness of material is obtained.

Mixing and Application

Please refer to the product datasheet for details.
