Rich1972 Posted February 19, 2010 Share Posted February 19, 2010 OK, one fireplace at the far end of the house has not been used for years and the slim firebricks against which the fire was built are in a very bad condition i.e. bits missing, crumbling, cracked, to a depth of about two inches in some places. They are badly eroded and need replacing before I have a woodburning stove and flue fitted. I think I can get hold of some reclaimed firebricks easily enough but is it a relatively trouble-free job to ease out the most damaged ones and replace them with the reclaimed ones? The area I want to repair/replace is about two feet wide by 18 inches high. I'm unsure which mortar I should use. The original mason used what appears to be a very hard, red sand, totally unlike the clay/lime mortar that was used in the walls. Has anyone done this before?Rich [:)] Link to comment Share on other sites More sharing options...
Bugsy Posted February 19, 2010 Share Posted February 19, 2010 Advice as it was given to me.Mortar mix: 3 parts brick layers sand, 1 part hydrated lime, 1 part fireclay and 1 part portland cement.Joints as thin as possible, and certainly no more than 1/4".Hope this helps.

Théière Posted February 19, 2010 Share Posted February 19, 2010 Hi Rich1972, it needs to be repaired with a fire cement, I use Pyruma in the UK but you should be able to refractory cement in some of the shops near you Link to comment Share on other sites More sharing options...
powerdesal Posted February 20, 2010 Share Posted February 20, 2010 Maybe a silly question, but...........If you are having a woodburning stove fitted why exactly are you wanting to replace with specific firebricks? Link to comment Share on other sites More sharing options...
