## Questions & Answers

**Q: If the concrete slabs are 1 inch apart, will this work? I could not find any 1" being sold... Should the rope seal be the same width or smaller width?**
A: You want to fit the gap. If the backer rod was too small I put in two rods of different sizes to fill the gap. Took some work to make it fit ok and look ok but once I put in the self leveling chalking it looked good. If there is a gap around the rods the chalk will seep down between. Not good. 
Could use a different chalk type but I liked the look of the self leveling after it dried.

**Q: Where is this product manufactured?**
A: Made in USA.

**Q: Will this work between the tub and tile in the bathroom?**
A: Hello. Sika Backer Rod can be used in this application if the sealant installation to follow calls for a closed-cell backer rod. Thank you for considering Sika!

**Q: Can this be used to seal between facia boards and brick wall to keep bats out?**
A: We used this to fill big cracks in our driveway and then used concrete sealer over that.  I suppose you can use it for your purpose.
