Worked Extremely Well!

Deborah LewisNovember 25, 2023✓ Verified purchase

I was looking for something to adhere small glass bowls (to hold candy) to plastic for some Halloween decorations. I had to make about 20 of them and I needed something that 1, wouldn't come undone if the plastic and/or glass became cool due only to normal conditions, and 2, didn't have the strong, horrible odor. This was the miracle adhesive! I am a DIYer and have been using another popular adhesive for a very long time. No longer. Don't get me wrong, the other product works great and frankly is cheaper. But the DAP 688 did everything I needed and had no lingering odor. It is advertised to repair aquarium glass so it must be safe for fish. Plus, if it could hold glass together in water, I figured it would hold glass to plastic! And it worked great!!! If you are looking for something you can use inside, try this. Great product.

Works decent, but would pay double for a cap for the nozzle...

C. MoellerAugust 4, 2019✓ Verified purchase

It comes with a nozzle you can clip to dispense the product- but no way to cap it, or clean it. So plan on it being one time use, unless you don't need to use the nozzle. Pros: * Turns into clear silicone * Didn't blow out the back from pressure, like some other reviews Cons: * No cap for the nozzle (so one time use if using nozzle) * Very sharp/ acetic acid smelling when applying * Didn't stick to 1/2" black rainbird tubing I was trying to use it to create a water tight gasket around a tube for hydroponics. I waited 24hrs, and the tube pulled right out, but the silicone stayed in place. So I'm going to try sand papering the tube some and try again, and hope it sticks to it (it's the 1/2 black outside irrigation tubing). I'm going to also try rubber grommets instead, but this would be cheaper and more versatile if I can get it to work. Read more

Food Grade Safe

Food Grade worked great to cover rusted dishwasher rack. Read more

Coats dishwasher rack repairs very well.

D. HesselbarthJuly 15, 2025✓ Verified purchase

The food grade rating allowed me to use this to coat repairs to my dishwasher rack. I've used the special vinyl coatings sold to repair rusting areas of a dishwasher rack, but I've never found them to last very long. After removing rust and coating the affected area with a rust inhibiting paint, I liberally coated the repair area with this material. It has held up well in the very harsh environment of the dishwasher. Read more

this really worked

VeeGeeBeeJune 5, 2014✓ Verified purchase

I have a plastic birdbath that got a crack in the bowl, and as birdbaths are so pricey (to replace this exact one would be about $50), I tried to fix it myself. Used an entire can of that spray on sealer, sprayed the bottom as I didn't want to hurt the birds, well, that stuff didn't work at all, still leaked. Then I saw this, read the reviews, saw it was fish safe at least, so, got it. I cleaned out the bowl part of the bath, let it dry and then opened up the tube. I did not use the little plastic nozzle that came with it as I felt it was too large for the hairline crack that ran across the bowl. Instead, I improvised and used one of those little plastic identification tags that are placed inside the potted plants we buy. Decided the pointed end of it would be what I needed to "trowel" the adhesive into the crack. It worked really well, I was able to use my new "tool" to spread the DAP product into the crack and slightly on either side of the crack, and level it out. I did not notice any smell from this product, which was good as I have gotten sick from glue smells before. Took me about 10 minutes to get it the way I wanted, and I let the birdbath sit in the sun for 2 days before trying to put water in it, when I did--NO LEAKS!! I let it cure one more day and then filled it with water and put it back under the butterfly bush, where the birds have been using it since! Nice to have the birdbath back again, and I hope it really doesn't hurt critters as they advertise! Read more

Excellent for fixing a broken dish, food safe

Sarah LApril 20, 2023✓ Verified purchase

It was very easy to work with this product. I liked that the drying time was slightly delayed, as repairing a broken dish requires patience and precision. It was very important to me to use a product that is verifiable and absolutely food safe per ANSI/NSF and/or FDA standards. *There are many products out there that claim to be food safe, but you have to actually look for that information to be stated on the product or the product’s manufacturing site. Also, if a chemical product is not made in the United States, don’t buy it, as this information is almost always impossible to find and intentionally omitted. I visited dap.com and verified the safety information on the MSDS (material safety data sheet) as well. I made sure that I had plenty of ventilation, but honestly, there wasn’t much of an odor. Make sure that the opening that you create at the tip is large enough! A safety pin is not wide enough for the viscosity of this product, fyi. Read more
