Food Grade NSF FDA RTV Silicone Sealant Adhesive Red High Temp 10.3oz (Standard Version) (Standard Version)

Great stuff, will buy again. Use a wire nut to seal back after opening, works better than a screw

Used to seal chest used to create mist for creeping fog at Halloween. Does a good job at sealing it up.

Easy to apply. I like that the tube was molded closed and you cut the plastic away to open the nozzle. This is much better than the caulk tubes that are sealed with foil. Doesn't smell, I used it indoors without issue. Adheres very well on vertical surfaces. You get about 10 minutes of working time if you need to tool it around to get the right coverage or thickness then it skins over. Bottle says it fully cures in 24 hours.

I used this for my offset smoker and it worked adequately. Some of the higher temp areas deteriorated, but that's to be expected.

The bottom of my oven developed a couple of small holes from crinkling from thermal shock, so it was not holding its temperature very well. But this sealed up the holes easily and my oven holds its temperature once again! I originally bought this a couple of years ago and simply reapply it every six months. It lasts a long time! As for someone mentioning that its food safety is questionable because they only saw it on a sheet of paper, it has the NSF logo right on the bottle.

Used for a bbq pit. Workes like a charm

I use this for high heat, and food contact places. I grow micro greens in a hydroponic system and use this to seal edges for custom hydroponic NFT tables for automated watering. I also use it on high heat application in my mushroom grow facility where I cook sawdust for 24 hours at a time. Works great, really good bond, never fouls after opening if you seal it properly, and I always keep an extra tube on hand.

This is the BEST sealant I've ever used. It's the super glue of sealants. It's FOOD SAFE. You don't need much to adhere smooth surfaces, even to smooth concrete. It's got a STRONG vinegar smell which goes away in a day or so It ain't cheap but it's the moral high ground if working around water, sinks, kids, anyone concerned about chemical safety and should ensure no call backs. If using in finished area you'll need to hold back and cover over once cured with something more decorative than it's screaming orange red color. I say hold back rather than just paint over, as any peeled paint will leave a GLARING problem and call back.
