Easy to use, good quality

7 months ago
Used this to caulk between my backsplash and countertop after removing a granite bar. It’s a temporary fix while we wait to replace the backsplash but it worked well! It was easy to use with the adjustable nozzle and easy to guide the product where it needs to go without a caulk gun. Would be nice if the tube was larger but this one was large enough to complete the small project I needed. So far it does not appear to have any shrinkage and dried without any issues or peeling. I would buy this for another small project for sure! So much easier than getting out the caulk gun unless you have an entire bathroom or kitchen to do.

This caulk sealed the area great with no sagging at all. It was quick and easy to apply. The tube revealed easily when the job was done. The caulk adhered great and looks amazing.

Best Caulk Sealer

7 months ago
This has to be the easiest Caulk that I have ever used in my life! I didn't need an attachment; it is built in. You simply turn the top, and pop the handle to allow for the caulk to squirt out. It doesn't have an odor, and it doesn't shrink over time. It's very sticky, but also extremely durable. The finished product after applying it to the surface looks so professional.
