## Questions & Answers

**Q: Is this the product to seal the expansion joints on a sloped driveway?**
A: This is what I would use. It's thicker so it stays put pretty good. Use rubbing alcohol on your finger to smooth it. It won't stick to your finger.

**Q: My concrete deck is more of a red sandstone color.  do you have self leveling for that?**
A: I would suggest that you order the limestone color and purchase some brick colored concrete tint powder to mix with it prior to application.

**Q: Is this paintable**
A: I don't think so

**Q: Did you have brown?**
A: We do not have the Sikaflex 1A in brown.

Thank you.

Excellent product .

### ⭐⭐⭐⭐⭐ Best stuff ever!
*by G***A on July 3, 2025*

I’m giving a five star because the batch I received has a 8 month shelf life and the previous two batches also had a long shelf life, which seems to be rare when it comes to Sikaflex. Sikaflex 1a is the best stuff you can get. It works on everything.. Don’t use it on something you plan on taking apart later lol it’s permanent stuff. If you’ve never tried it, you must get some because every contractor and handyman should have this product in their arsenal. It works great on concrete, wood, roofs, and almost everything else.
