- 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
Please Note: This Product is made to order subject to an extended lead time of approximately 35 working days

Maurice Langdon on 2020-12-13 23:42:50 | Question:
Have a situation where Sika 740W has spilled over onto powder coated surfaces. Intermittant spot stains showing - how do these get cleaned off without affecting the powder coating |
Answer from Rawlins’ Technical Team:
The manufacturer recommends cleaning with water immediately after use. Hardened / cured material can only be mechanically removed. | |
William Ferdinandsen on 2017-02-27 17:07:42 | Question: In general, how long does the product last on a new bridge in a marine environment? In other words, how long before the product should be re-applied?
Thank you,
Bill |
Answer from Rawlins’ Technical Team: Sika do not offer design lives for these types of products, but it is fairly common place for hydrophobic impregnations to be re-applied every 2-3 years. However that is if the product is used singularly instead of as a full part of a concrete repair system. | |
