Hi All,
I have built my first pizza oven and the dome construction is complete. I'm about to insulate and build the chimney.
I aim to build the chimney from the remaining firebrick as is the front arch. All of this firebrick will not be insulated and left to the elements. My worry is that with the firebricks being porous then these will constantly be absorbing water and causing issues considering these should be dry.
How can I resolve this? Should they be covered? I have seen that people have left the firebrick open to the elements on the dome front but should I cover the sides and chimney?
Is it possible to seal with sealant? I have made polished concrete worktops so these will be sealed also. Can I get away with using the same?
Any help is appreciated? |

Any help is appreciated? Hi, I spent a while debating this myself (see my profile pic, the brick arch door, made from firebrick is exposed). I did use ronseal brick sealant and it seems to have worked (I cannot apply a second layer, the aqueous based sealant just runs off). My thinking is (and my oven is in a relatively covered area under a thick tree) that it'll be OK for the summer but will tarp it for the winter. Take the above with a pinch of salt- I only finished mine a few weeks ago, so little practical experience. |

I was hoping sealing them would do the trick as I don't want to keep mixing the brick. I welcome any other thoughts on this |
