![]() | 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:
The manufacturer recommends cleaning with water immediately after use. Hardened / cured material can only be mechanically removed. | |
![]() | 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: 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. | |
