Sika Sikagard 740W is a one part low viscosity, reactive impregnation for concrete and cementitious substrates based on concentrated Silane emulsion.
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 sea water
- Ready to use
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 surface, use flooding technique but avoid excessive ponding on the surface.

The manufacturers data sheets are available for download from this website. It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
Customer further agrees that Promain have no liability for any errors or omissions contained within the Product Data Sheets and are not liable for failure due to misapplication or inadequate substrate cleaning and preparation. For more information please refer to our Terms & Conditions.
