Mold Armor100% Silicone Mold Free Caulk & Sealant (White), 5.5 Oz.

It's sealant ,what can you say. Goes on easy , clean up with mineral spirits before it skins over. A little stinky , but VERY mild resistant . I've used this item before and recommend it highly.

I've been a contractor for over 30 years, and this is the best product I've found. It lasts the longest, finishes nicely, provides enough working time, and blends well for touch-ups.

Works well for it's purpose!

Easy to use.no need for the gun .i just just wish it has more color options. Last long not easily removed if applied correctly.alow time for drying

Works great. It's been on my tub for about 3 months. Still no mold or mildew

Some reviews indicate that white caulk was ordered and that clear caulk was received. I had white and clear in the same tube (see photos). The first inch of caulk out of the tube was clear and had a lower viscosity than the following white. My guess is that the clear material had a lower viscosity and slumped due to the absence of titanium dioxide pigment, but it could be something more problematic. If this was epoxy I could stress test an assembly, but this is caulk and only time will tell. The information in the third photo might help the seller correct the problem.

This caulking was easy to apply and looks good. It was quite smelly during the curing period, but the odor quickly dissipated afterward. Two-thirds of a tube was enough to surround our tub, and it seems to make a good seal. I can't comment yet on its mold resistance as it has been in place less than two weeks, but I really hope it works--the former caulking in that crack was black with mold and I don't want to have to scrape it out again anytime soon. Here's hoping! I may update this review later to report on that.

Excellent caulk for the bathtub!! It went on smoothly, dries quickly and looks great.
