## Questions & Answers

**Q: How do I know how much sealant I need for a project?  Is there a usage quantity calculation?**
A: 15 LF of 3/8" bead per cartridge appx.

**Q: Will this work with abs plastic?**
A: If you are asking will Sikaflex bond to abs plastic, I think it will if you clean the abs with alcohol.

**Q: Is this the best product to seal/bind the edges of a rubber/turf (gym) floor to a basement concrete floor?**
A: I think it'd be a great product.  Super strong, durable slightly flexable. I've been using it to glue metal roof's down for the past 10 years and no issues.

**Q: Can this be used to seal inside of a rim on a spoke wheel?**
A: This should work very well for sealing rim of a spoked wheel.
I plan on using this product when I get around to doing mine.
