## Questions & Answers

**Q: Can this be applied outdoors when the surface is not completely dry?**
A: Better to use when surface is dry and temps outside are not below 40 degrees or above 80 degrees.

**Q: Will this work on cracked and chipped linoleum?**
A: I don't recommend it. I would recommend clear epoxy cement and then use a fine sandpaper once the cement is fully dry.

**Q: Is this really white after it dries? Bought another brand that was supposed to be white, but it was clear, which doesn’t fit my purpose.**
A: It dries white.

**Q: Can this be used to caulk around a tub and shower?**
A: I probably would't attempt to use as the humidity in a closed bathroom is different than the humidity outside.
