If so, how thick and thin can the layers be applied?..** A: I used CleanBurn over a ceramic fiber blanket that I used to cover the sheet metal firebox and flue in my outdoor fireplace. I covered the blanket with chicken wire and patted the mortar into it. Then I coated with another thin coat of mortar. It set up really hard in 24 hours. Total thickness 3/4" to 1”. I finally coated the whole box with coloring and some regular mortar. It looks like stucco now... Pretty nice. Inside a foundry you'll need the chicken wire to hold the blanket up and give the Cleanburn something to stick to. - Mikee **Q: What are the drying procedures for this product? Can it be used in a forge?** A: Hello, For drying time, the cement will set between 9 & 10 hours. Heat can be applied 24 hours after the mix has been set. This product can also be used in forges. Thank you, **Q: Is this suitable and safe for the cooking surface of an outdoor pizza oven?** A: I used this to repair a chiminea. I would not use it as an actual cooking surface without researching all the materials in it. You could cover the surface with a good quality clay. That would work. Nice product. Easy to work with. **Q: How thick does the cement have to be for the floor of a fire box in a coal fired furnace? The fire box is 24" in diameter. How many pails will I need?** A: Depends on a couple things like what type of base your pouring it on and if it has insulation or not; example; if the base is a sturdy steel plate, then that will help hold the form better and the less refractory needed.. But if the base is unstable or flexes, then you will need a thicker layer of refractory.. Also the insulation factor is relatively low with this refractory cement, so the thicker the layer the better the insulation.. but one pail should give you a decent layer on a 24” diameter fire box.. and I’d say a 1”+ layer should be okay. ## Frequently Bought Together - Cleanburn 25 lb.
