Water Repellants

One part water repellent impregnation for absorbent cementitious substrates. It penetrates well into the open pores of the substrate, providing durable water repellency, while still allowing water vapour diffusion in both directions. Complies with the requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class I).

ADVANTAGES

• Reduces efflorescence
• Does not act as a vapour barrier
• Reduces capillary water absorption
• Reduces chloride ion ingress and movement
• Does usually not change the appearance of the substrate
• Can be overcoated with solvent based and dispersion coating
• Reduces dirt penetration into the poresImproves thermal insulation
• Higher durability and resistance than conventional silicone based treatments
