A Good All-Purpose Silicone Sealant & Caulk
I caulked the space between my deck and the house wall to keep water from collecting there. This silicone caulk fills gaps and sticks tenaciously to standard building materials. My tube came without the removable tip. I emailed Amazon that day and had a replacement tube - with tip - two days later. I returned the original tube to Amazon through their Kohls product return program. No wrapping or posting. Very simple.

It's messy!!
Update.. Even though my review was correct. I changed the stars to 5 stars because as a company these people are very respectful of their customers and they issued me a refund andI wasn't even asking for one.. Order from them with convenience because they are a good company..... black doesn't have the texture of regular clear silicone. It was a bit thinner than normal silicone. I had bought a black Alan & Roth kitchen sink from Lowe's and I wanted to use black instead of clear. This wasn't a bright idea on my part. Good idea considering my sink was black but bad idea. This stuff was so nasty looking and messy. I spent almost an hour using alcohol to get it back off. I tried wiping it back off with just some paper towels and then an old rag and it just wasn't coming back off it was staining my hands and counter. If it wasn't for me having some rubbing alcohol on hand I don't know what I would have done. Will never buy black silicone ever again from anyone.

It's good caulk
I had to modify a caulking gun because I have 3 and it didn't fit any of them. It's because the screw-on tip is a larger diameter than normal. It is made in Turkey so maybe their system is different. The caulk itself worked well though and I was happy with it so overall I was satisfied.

Great grade of viscosity with shiny finishing !
I used this on my kitchen’s countertop and sink I loved the way you can handle this sealant, is not as messy as other thicker ones and the tip applicator makes your DIY tasks easier. When is dry the finishing is shiny. So far is free of mold and looking impeccable.Great product!

Great Product
The adhesion is great- I also liked the grey color, it was very similar to the concrete in my driveway.

It's messy and the tip comes with too big of a hole in it from the factory.
This review is for the product only; I cannot speak as to the company selling it. I am quite experienced in residential construction and have become quite adept at caulking over the years.With that said, I purchased this because it had overnight delivery for a next day project that I didn't have the time to go to the store for. I have two dislikes about this product. First, it is very messy and second, the tip of the applicator comes from the factory with a sizeable hole already in it, which made it impossible to cut the small size I needed to lay a thin bead. This only added to the messiness. Next time I will just go to the lumber yard or hardware store so I can see what I am getting. It would have been quicker than cleaning up the mess. Definitely steer clear if you are looking for an easy to control product and are needing to lay a thin bead.
