  • practically invisible
  • negligible volatility
  • solvent-free
  • good alkali resistance
  • highly water-repellent effect
  • very high level of penetration
  • can be applied to fresh jointing
  • reduces salt efflorescence, frost damage, mortar leaching, moulds, moss and algae growth and erosion, etc
  • can be applied to relatively moist and warm surfaces 

Recommended Uses 

For making brick, concrete, asbestos cement, sandlime brick, joint mortars, aerated concrete etc. water-repellent.


Theoretical: 0.1 - 0.4kg/m2
