Sikagard 705 L is a silane based reactive water repellent penetrating sealer


Product Data Sheet


Sikagard 705 L is a one part low viscosity, solvent free, reactive impregnation for concrete and cementitious substrates based on silane technology with 99% active ingredient. Complies with the highest requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class II & resistance to freeze-thaw cycles and chloride ion penetration).

Where to Use

Sikagard 705 L is used as water-repellent penetrating sealer (hydrophobic treatment) for absorbent substrates such as:

  • Parking decks
  • Bridge decks
  • Concrete highway surfaces
  • Ramps and Barriers
  • Cooling Towers
  • Stadiums
  • Natural stone substrates
  • Many other traffic bearing/reinforced concrete substrates and structures


  • Excellent penetration (~100% active content)
  • Economic and easy to use
  • Reduces capillary water absorption, protection against driving rain and splashing on vertical areas.
  • Reduction of absorption of aggressive or deleterious agents dissolved in water (i.e. de-icing salts or chloride from marine environment)
  • Non vapor barrier
  • Long term efficiency, deep penetration
  • Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
  • Low VOC content
  • Resistant to sea water
  • Ready and easy to use 


  • Dependent on absorbency of the substrate as well as the required penetration depth: 240-360 sq.ft./gal per coat

Cure Mechanism

  • Sikagard 705 L does not require any special curing but must be protected from rain for at least 3 hours at +68°F.
