## Questions & Answers

**Q: can you paint over this caulk?**
A: I found it worked perfectly to prep small wall cracks prior to painting.  Quick drying time.  Also - just a thin smear along the edge of masking tape (baseboards) made for nice sharp sharp lines.  Recommend!!

**Q: Can this be used to seal the edge of a linoleum floor?**
A: I don’t think caulk is for sealing. Search for a sealant instead

**Q: Is this good for kitchen counters?**
A: Don’t believe so

**Q: can you use this for outdoor porch lights**
A: It does say for exterior use. So I would guess the answer would be yes.
