## Description

Sikaflex 1A is a premium grade, high performance, moisture cured, 1 component, non-sag elastomeric polyurethane sealant for forming permanent, water and weather resistant seals in exterior gaps and joints. Sikaflex 1A is excellent for small joints and fillets, windows, door frames, reglets, flashing, roofing detail applications, and many construction adhesive projects. Sikaflex 1A can be used in both vertical and horizontal joints where the maximum depth of sealant is 1/2 in or less.

Review: Great stuff!! - I used this to fill the expansion joints in my driveway. They were all old and failing, peeling out. When I blew several out with my leaf blower I realized they need to be replaced. I chose this from recommendations of others I have talked to. Works fantastic!!
Review: Great for my pool - We put this under the pool coping and after a hot dinner showed minimal cracking and had not peeled off at all. Should last another year or two before we may add another coat. Pretty easy to work with. Pleased with it.

## 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.
