## Questions & Answers

**Q: How do you clean up the caulking gun?**
A: remove caulking tube....throw away....If, the remaining gun is a mess...throw it away...

**Q: The heading says "White" the picture says "Concrete" and the specs say "Black".  What is the color of this caulk?**
A: The color for the tube of caulk is at the top-which says "white"; "concrete" refers to its application, but be assured, the application is way more than to just concrete. Don''t know why the description says black; probably a goof up. The color is white.

**Q: Would this work well on black asphalt, adhesion and flexibility?
Karl**
A: Karl, I talked to DAP tech service. They said it would work for a asphalt application. If you look at there web site it says will withstand vehicle traffic.

**Q: How many linear feet does a tube cover?**
A: i guess it depends on how thick you lay it in.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good grip, but give it time to dry.
*by R***Y on 22 February 2019*

Used this on an unusual application on nylon felt. Good grip strength. Bonds to glass really well too - by accident. It would be nice to have this come with a wire to rupture the membrane at the base of the nozzle - or a shorter nozzle - it is too long for any commonly available nail to reach.
