FOR IT'S REAL PURPOSE: Used it to redo a stretch of the kitchen counter. Worked great!!! FOR UNUSUAL USE: Diluted it with mineral spirits, colored it with acrylic paint, and made some rock molds for plaster casting. Worked great in both applications!!! WOULD RECOMMEND!!

Easy to use, worked perfectly for the project that I needed it for. I used a caulking gun and it was really simple to apply it and spread it, and it dried and cured well. Very satisfied with the product.

As recommended I use this to secure things in my turtle take and to keep it water tight. This is the exact brand used by most aquarium builders.

Love the smell. Lol they asked me about scent for this review. But if you need this you probably don't need a review? Good brand though

-effective -dries in less than 10 hours -scentless when dry -dries as a light/cloudy white...not a bright white or bathroom-tile white. I used this to caulk in between the gap of my door molding and floor by the front door. It is effective in limiting bug access into my house, which is the reason behind the caulking in the first place. This definitely has a STRONG smell when wet, but is scentless when dry. The "color" is a cloudy white color...almost like a "foggy clear" color. CAUTION to new users: After you "snip" the lid of the bottle, you must stick a long, thin rod down the nose of the tube to pop the can so the caulk can come out. Also, this must be used with a caulking gun..can't be used on it's own as a tube of glue. I know that is standard for caulking, but as a first-time caulker those are things I had to research myself. haha

I make silicone molds for resin casting used in my artistic projects or prototyping (poor man's 3d printer). With the expense of "mold-making" silicone reaching the stratosphere, I have experimented with construction-grade silicone and find most construction brands to work equally well as the expensive silicone. This product is the lowest priced, 100% silicone I could find on Amazon and creates a superior quality mold. In order to make it workable like clay (instead of the sticky mess it comes as) get a large mixing bowl and add about a quarter cup of unscented dish soap to about a gallon of water, then one full tube of this caulk. Start kneading the mixture and the dish soap will rapidly cure the silicone in just a few minutes. Pull it out when it's at the cure-state you are looking for, and push whatever object you're trying to clone into the semi-cured silicone. Then air dry the rest of the way until fully cured. You can use some inert filler if you're trying to stretch the batch by curing the silicone a little less in the soap-water and mixing in something like corn starch. This obviously affects the temperature tolerance of the mold and tampers other physics properties of the silicone, but that may be ok for your purposes (e.g. you're casting glass tiles, wall outlet covers, or something that doesn't generate massive heat). I've added corn starch a couple times and wound up with a mold that still worked well. Great stuff on the cheap!

I always have a tube of Silicone 1 in my caulking gun, mainly for aquarium projects, but it will adhere to just about anything. You can't beat the price, especially compared to "aquarium silicone". I like to let it dry for at least 48 hours before putting anything in the tank. Great for gluing rocks together in formations, and years in the water doesn't affect it at all.

Not much you can say about a tube of silicone caulking compound. At least it is sold by a American company. I cannot attest to where this product is actually made but I hope at least some of the profits go to Thomas Edison’s company. If you study history you know that Thomas Edison‘s standard electric turned into today’s general electric.

It's 100% silicone, this type of silicone is aquarium safe. I've been using it to re-seal old aquariums to be used again and it's worked perfectly.

I used this in my aquarium and it worked perfect!
