how do you apply this cement to line the inside of a fire pit / bbq. How thick and apply with what? Instead of using fire brick? Thanks !!

The castable cement is supposed to withstand temperatures of up to 2200 degrees. It is to be used with firebrick having the same heat characteristics. It is used in making high heat forges. I didn't know any better and used it to make an outdoor Pizza / Bread oven. Pizza is range 550 -600 deg. Bread is 360+ / - degree range. Later found out - and used- 1 part portland cement - 1 Part Fire Clay and 3 parts sand to coat the outside of the oven. this mixture is rated for 700 degrees. I doubt your fire pit will get near this level of heat. All that considered, It is an excellent material and it is expensive.

This is a self leveling product. It thins during the curing process and becomes runny so a border would be needed to contain it. I haven't used it at a thickness greater than 1/8th inch so don't know how it would respond thicker than that.

Hello Irtafa, The type of foam you should use and recommended thickness will depend upon what you're spraying to. What type of area do you need to spray? It may be easiest for me to help over the phone. If you get a chance, please give us a call at 800-516-0949 so we can help you get your project underway. Thanks! Linda Foam It Green

This product should be able to be used on the exterior of a fireplace, so long as it is Concrete, Block, Brick, Stucco, Stone, or Wood. Since it is a waterproofing agent, it should be able to be used "on top of" a fireplace also, since heat should hot affect its performance. Reapplication is dependent on many variables (density of material, horizontal/vertical surface, number of coats applied, temperature at application, exposure, wear factors, etc) so only time will tell. When the product is no longer preforming, it is time to reapply. Under the best of circumstances they warrant it for 10 years (see conditions) but I'm only hoping to get 2-3 in my application.

As great as Mortite is, it is NOT intended for high temp applications!! I can't tell you the actual melting point but I can tell you that you can set it on fire with an open flame. Do not use it around your fireplace, please.

Small open flame is good , all depends on the application.Keep the flame low and even then apply solder. good luck

Wood burning fire pits put out a LOT of heat below. The safety will depend on the distance from the fire pit to the deck. You might be ok if you also add in some kind of a heat brick between the pad and your fire pit. Your best bet would be if you could get a 2'x2' patio brick and then elevate it an inch or two under the corners. That should absorb most of the heat from the fire pit. Truthfully though, I personally still wouldn't risk it. I'm in a similar situation, and I'm looking at propane fire pits. Pricey, but a lot safer for decks. I know my township will not issue a burn permit for a wood firepit on any deck. Wood burning fire pits put out a LOT of heat below.

Sorry, John B's reply is WRONG! Do not put this over paint. That is practically akin to spraying water over the paint. No kidding! No chemical reaction with the cement means NO barrier and a complete waste of money.

Brutus could handle thick cement. It's got a good amount of torque. We mixed both stucco and lime plaster. They're both thick. And Brutus did a great job mixing them.

Above paint? I'm not sure. Altho I sealed up my chimney and red paver patio with it, seemed to the trick. Will know more come spring &#128522;. It does defiantly give the stone a darker more complex look overall. So far satisfied.

I probably should have answered "I don't know". I used this product to install crawl space vents in brick veneer openings. I'm not competent to install them with mortar. It worked well as long as you can leave it undisturbed until it somewhat "cures".

I think flashing cement might be a bit to viscous but it might work. Keep in mind you will have a pretty wide pattern.As far as mortar mix, it would shoot it, but I think it would need to be very wet in order to flow into the gun. The opening at the top of the gun is around an inch in diameter but then the material has to flow into a much smaller opening , say 3/8 inch or so, into the air mixing chamber.You might also need to bore out the largest nozzle a bit to handle the sand.My advice would be to rent one first. Handling a gallon of anything is heavy and a bit tiring so not sure a gravity feed gun is the answer for those products. I think flashing cement might be a bit to viscous but it might work.

I used Herculiner to apply over metal & wooden decking of my fishing boat. It is great to apply to those materials as it sticks like it's welded to the materials. One thing about applying is to use it up quickly using the supplied application rollers. After using the two they sent with the Herculiner I never found anything that would work well. Herculiner needs to supply more than two rollers. I do not know about adhering to brick.

This seal works very well on the cooking/smoke chamber, but degrades very quickly on the firebox. Its rated up to @ 600 deg F. For a larger smoker I'd go with the small oven type of metallic or pyrosil fiberglass seals like on a wood stove. Its more expensive but worth the investment. You can find it on Amazon, I think Garland is the brand name.

Hi I've always had good luck with duct tape, just make sure it is stuck well along the crack so it doesn't leak when the epoxy heats up/kicks. Are you using a filler or just straight liquid epoxy? You probably already know this, but it's best to thicken it with one of the thickening agents, like colloidal silica. Cheers Brian

You can use white glue. I have heard that hot glue also works. Personally, I'd go for good old rubber cement. The main thing is to avoid any glue containing sulfer.

It will form a solid patch, but as you suspect the color would be off (for me it dried a dark gray). I do not know if you can mix it with brick dust to match the coloring. I suspect that mixing it would change the consistency and then you'd have to mix in water or another liquid to maintain it. It could prove complicated, messy, and may alter the performance of the product.An alternative could be to use the patch to partially fill in the hole, and then find another product with the appropriate coloring to top the hole off with.
