This product is WAY easier than caulk in a gun. Not even the fact it does so much more for way less. 10/10

The caulk did not come out well. Really had to mess with it and it was incredibly sticky. Hopefully it will last a long time.

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.

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.

I recently tried the MOLD ARMOR 100% Silicone Mold Free Caulk & Sealant (White), 5.5 Oz, and while it did the job adequately, there are some notable aspects to consider.Firstly, in terms of performance, the caulk and sealant worked okay. It effectively sealed the intended areas and helped prevent mold growth, which is crucial for maintaining a clean environment.However, the notable downside is the strong smell associated with this product. Initially, the odor can be quite overwhelming during application, but thankfully, it gradually fades away after the caulk dries. While the smell is a temporary inconvenience, it's something to be aware of, especially if you're sensitive to strong odors.Overall, while the MOLD ARMOR Silicone Mold Free Caulk & Sealant gets the job done and effectively eliminates mold concerns, the initial smell can be off-putting. If you can tolerate the temporary odor during application, it's a decent option for mold prevention and sealing needs.
