## Questions & Answers

**Q: Is this a good product to repair  hairline cracks in stucco?**
A: Yes. I used it on a foundation and it worked great!

**Q: Is this good for sloped concrete pads?**
A: Depends on how severe the slope is but it should work otherwise.

**Q: Can you use it to reset a loose fireplace hearth stone?**
A: For that I would use a construction adhesive, not a caulk.

A: I've used this product on inside concrete cinder block walls with no problem. I like its textured consistency. Know that this product will break down over time when exposed to direct sunlight like a west or south facing concrete outside wall.
