Application instructions

Substrate pre-treatment:
  • Chip out damaged mortar with a utility chisel
  • All surfaces to be coated should be free from dirt, dust and loose material.
  • Any cracks in the surface must be repaired and the surface pre-wetted before work commences.
  • Any free surface water must be removed immediately before application of NCL Proplast repair mortar.
  • Care should be taken to ensure that NCL Proplast repair mortar is thoroughly mixed. It can be handed in small amounts of up to 2.5-3 kg. Without difficulty.
  • Add the powder to the water and mix with a spatula or trowel until a smooth workable consistency is achieved.
  • Mixing ratio: 1-1.25 lit of water to 5 kg material.
  • Fill horizontal joints first then vertical joints
  • Apply by trowel in 1 or 2 coats. The time intervals between coats should be 2 to 3 hours.
Curing treatment NCL Proplast repair mortar cures with minimal shrinkage. If exposed to rapid drying  conditions keep the surface wet to prevent premature drying. If wall temperature is more than 35 degrees centigrade, give at-least two curings.
