What Customers Are Saying

Customers overwhelmingly praise this caulk for matching grout colors with remarkable accuracy and enhancing tile appearance. Many highlight its ease of application, smooth workability, and suitability for touch-ups without messy mixing. Reviewers appreciate the wide color range and clean lines achievable with painter's tape. However, some report concerns with slow curing times and cracking after drying, while others mention it remains tacky or isn't paintable. A few find it overpriced compared to alternatives. Despite these drawbacks, most customers consider the color-matching results and convenience worthwhile.

Best Caulk on the Market

Absolutely the best caulk I have ever applied. Seals and defined edges make it a great finish/sealer for any application. Perfect for showers and sinks

I purchased this to seal the bathtub where there were crack in the grout along the tub. It worked much better than I expected. It has only been there a month but I am pleased with the results so far.

Match black grout well

 Would Recommend

Color matches well. It’s hard to find a black caulk for showers and this one is readily available in store. Cures pretty fast

I love that this is available in different colors!! Very easy to use . Looks like grout but is 100%. And waterproof!! I have purchased different colors of these for projects in my house (kitchen and bathroom) because they are waterproof. I can say I would definitely purchase again!!

Perfect for the cracking grout in my shower. Good color match for the grout already there. Quick application, good consistency, right amount of curing time. Too soon to tell if it will solve all the issues I am having with the shower.

Reduce repairs.

Bought this product to fix grout that had cracked because of imperfection in floor level. It has blended perfectly with existing grout and provides the flexibility to work without completely removing tile a re-setting.

Wrong product for the job

 Would Not Recommend

This was recommended by an associate to fix my shower stall floor. I didn’t realize it had silicone in it until I was squeezing it out. Totally the wrong product for the job , so now have to replace the whole floor. More training needed
