Where to Use

Sikagard-740 W is used as water-repellent penetrating sealer (hydrophobic treatment) for absorbent substrates such as

  • Walkways and ramps
  • Industrial floors
  • Exposed aggregate
  • Pre-cast or pre-placed concrete
  • Masonry
  • Parking decks
  • Stadiums
  • Bridge Decks

Advantages

  • Good penetration
  • Economic and easy to use
  • Independent test data available
  • 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. chlorides)
  • Not a vapor barrier
  • Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
  • Water based emulsion, Low VOC
  • Resistant to sea water
  • Ready and easy to use

Coverage

  • Coverage is entirely dependent on the porosity of the substrate. Extremely non-porous substrates may only require 1 coat. To ensure proper penetration depth, a field mock up is recommended: ~ 240-380sq.ft/gal

Packaging

  • 5 gallon pail, 55 gallon drum
