Sika Sikagard 740W is a one part low viscosity, reactive impregnation for concrete and cementitious substrates based on concentrated Silane emulsion.

Best Uses

Sikagard®-740 W is used as water-repellent impregnation (hydrophobic treatment) for absorbent substrates such as concrete in civil engineering or building concrete structures in both vertical and horizontal traffic area.

Sikagard® 740 W complies with the requirements of EN 1504-2 for hydrophobic Impregnation (penetration depth class I & resistance to freeze and thaw salt stresses) Sikagard®-740 W is classified as sealer Type 1b to the ALBERTA infrastructure and transportation specifications.

Sika Sikagard 740W is suitable for protection against ingress (Principle 1, method 1.1 of EN 1504-9), suitable for moisture control (Principle 2, method 2.1 of EN 1504-9) and suitable for increasing the resistivity (Principle 8, method 8.1 of EN 1504-9).

Good penetration
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. chlorides)
No change in water vapour permeability
Increases the resistance of concrete to freeze and thaw cycles and de-icing salts
Water based emulsion, Low VOC
Resistant to seawater
Ready to use

Application

Ensure the substrate is free of dust, dirt, oil, efflorescence and existing paint coatings. Cracks in concrete more than 300 microns must be repaired first prior to carry out the hydrophobic treatment.

Sikagard® 740 W is applied using a low-pressure spray, airless spray, brush or roller, in a single pass from bottom up taking care not to let the product run. Apply subsequent pass “wet on wet” until the required consumption is achieved. On horizontal surfaces, use flooding technique but avoid excessive ponding on the surface.

Sikagard® 740 W is part of the extensive range of Sika Products available from Promain.
