User questions & answers

Question:	Is disapproved by LA county
Answer:	Water resistant? Kind of but not submersible.
Question:	will this fix Crack in firebox
Answer:	You can't say one glue is better than another without knowing the application. This is great stuff though and now my general go-to adhesive. I'd still use E6000 for things that were porous, required more gap filling, or flexibility.
Question:	Can this be used to install wood stove door gaskets
Answer:	I have used it on glass that is for outside decorations. It worked great. Just allow 24-48 hours to set.
Question:	I'm looking to attach some tin tiles to sheetrock. Think this will work
Answer:	Yes, I believe it would be. It depends on surface... raw wood is good application for it. painted surface or plastic surface would not stick as well

User questions & answers

Question:	Is this product suitable for adhering graphite impregnated fiberglass rope gasket on a pellet-stove door
Answer:	Google "Curie Temperature" before using magnets on any type of homemade smoker,grill or stove repair. Because you chose this high heat sealant, I assume you'll be cooking or at least burning something. The sealant may hold the magnet to the desired object, but at a certain temperature, the magnet itself will fail.
Question:	Is this a non Petroleum based silicone? If so will it work with a cast iron boiler
Answer:	Hi, yes you can. It will cure within 1 day. There will be a slight vinegar type odor while applying that will dissipate. Thanks!
Question:	Can I use this to install stacked stone inside a metal firebox
Answer:	Hi, yes, it will then work, I just wanted to make sure it was not being used in a car engine. Thanks!
Question:	Any idea on how many 10.3oz tubes I should use for a chimney insert and top plate? Would 1 tube suffice
Answer:	It doesn’t say so on the tube but I believe that it is 100% silicone. I used it to caulk around a new fireplace chimney cap due to the high heat from the fireplace smoke when it’s burning. It should be great since it’s exposed outdoors year round

User questions & answers

Question:	Is this product paintable
Answer:	Not sure. It does work good as high temp adhesive though in my opinion.
Question:	Can this product be used on cement
Answer:	I purchased two and I based my decision on my experience of caulking tubs. Our fireplace is hand quarried stone so it isn't as uniform as modern built fireplaces. Also, Lee in mind, that I was using the caulk for fireplace glass doors and not an insert.
Question:	Is this product food safe
Answer:	No. Wires need to be conductive. Silicone rubber is a very efficient electrical insulator.
Question:	will I be able to seal a thermometer with this and dip it in oil that is no more than 400degrees
Answer:	This would not work. Car radiators hold water under pressure as it heats up. Radiator caps generally are rated at 15 pound per square inch before they realese pressure.
Question:	What color is it when it dries
Answer:	I believe it probably would, not sure you would need 500 degree temperatures though. you can buy a regular black silicone at the auto parts store. regular black silicone should work great on a wooden boat.

User questions & answers

Question:	Can you remove it if needed
Answer:	Believe the instructions are on the back side of the package. You can use acetone or paint thinner to remove.Its great stuff. Works well.
Question:	Can I use it to glue shower mirror to tile in my shower
Answer:	You can but it will probably leach through the mirror coating and appear as mold. Buy mirror mastic.
Question:	Would this be a good product for sealing a crack in a dishwasher liner
Answer:	Yes- I did this, along with filling in a gap on the dishwasher door gasket (which was ultimately replaced). Worked great! Be sure to clean the surface and rough it up a little (a bit of sandpaper, then clean the sandpaper dust off before application of the RTV). Used it a few years ago- is still sealed; all is well.
Question:	My portable convection oven (heats to 500 degrees) glass door fell out of the metal bracket. Would this work to glue it back in
Answer:	Be careful of sealant giving off toxic fumes the first few times you use it. Try heating up the oven 2-3 times before actually placing food inside that could absorb the toxic off-gasses.

User questions & answers

Question:	can this product be used on small exhaust leak
Answer:	I mostly use it for hot water applications. Used it successfully as a gasket on motorcycle by spreading thinly on both surfaces, letting mostly cure, and reassembling. Has held for over a year.
Question:	Could this be used to fill a small crack on a wood furnace firebox
Answer:	No
Question:	Could this be used safely on my Camp Chef smoker, between the pit and the lid
Answer:	Yes and no. you need to bring the repair area temp up slowly to a sustained 500° temp. Please see the helpful video. Do not use a torch or heat gun. This will bring temp up to quickly and damage your repair. Watch video. But since you have a gas fireplace this might not work for you.
Question:	outdoor weatherproof
Answer:	TDS: functional range reads (-75 degrees Fahrenheit to +500 degrees Fahrenheit) www.surebond.com
Question:	Is this paintable
Answer:	No, it is not food grade and should not be used where it can come in contact with food.

Question:	once cured does this smell

User questions & answers

Question:	If im using on my liner and insert stove, how long before i can have a fire
Answer:	Depends on how much movement (and expansion/contraction) your afraid will disturb your final product. - I'd give it at least 12hrs if not 24hrs.. to at least get it mostly dried, adhered and set.. It's a water soluble sand impregnated caulk.. (Hence, it won't go up in flames off-gassing) It will only dry out more with heat..
Question:	would this work to fix a crack in a panel of the refractory in my fireplace
Answer:	Yes this worked great for our fireplace panels. We had multiple cracks and applied this product with a caulking gun and then used a putty knife to smooth it out and pushed it into the cracks. It says on it that it IS NOT to be used on cracks larger than 1/4 ". It is rated for 2000 degree heat. Liked the price and 2 day shipping.
Question:	Can this be used to repair hairline cracks in a Kamodo ceramic firebix
Answer:	It’s all purpose fire place mortar so unless manufacture prohibits I would say yes
Question:	is this product water clean-up
Answer:	Yes it is.
