What material do you use for the roof of a masonry firebox?


Any advice much appreciated. What material do you use for the roof of a masonry firebox?

The discussion and comments here: http://www.livingstonemasons.com/ins...door-fireplace seem to indicate that you can just use cement for the firebox roof.

If regular cement is used for the roof, not refractory cement, should the cement be painted with high-temperature paint such as Rutland or AW Perkins?

I am referring to the ceiling (the gray, curved, top of the firebox) of the firebox, and I have attached a picture. Any help appreciated!


p.s. The bottom and sides of the firebox would be fire brick with refractory mortar. It is the roof of the firebox that I am concerned with.

The link didn't work 404. It looks like the roof was done a few times already. I don't know what happened to it. You want to add another coat of refractory mortar. Make sure that you chop any loose pieces first. I wouldn't paint it.


There is an interesting product ^
