Product is intended for exterior and interior use. Use with adequate ventilation when using indoors. DAP caulk and sealants provide durable performance for a variety of projects. Review: Good grip, but give it time to dry. - 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.

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.
