## Questions & Answers

**Q: If Backer-on screws are good for wet conditions such as shower enclosures, why aren't they approved for exterior use?**
A: I’ve used backer on screws for the exterior. If you look under epoxy coated screws they are very corrosive resistant and recommended for exterior although I will say that ceramic coated I believe her better.
