best mortar for repointing a chimney
what is the best mortar to repoint a brick chimney with? can i use FSB fiberglass bonding cement? ive heard if you use the wrong stuff the bricks can crack because of expansion/ contraction. any reccomendations would be helpful, thanks. also i have raked joints on the exterior but theyre not falling apart yet. only a few small holes and gaps. can i just put the mortar right over the old stuff or do i have to scrape it out first?
