Hi,
I have a 1930's semi and one of the internal walls runs all the way up into the attic across which a main timber roof beam rest and a timber strut stands vertical on top of the wall supporting a pitched roof. The wall is single brick but the mortar joints are all coming apart.
What type of mortar do i use to point this wall up in the attic - its about a meter high in the attic.
Will the lefarge ready mix mortar do or will it be too hard for the bricks. Need to know whats the right type of mortar to use on old bricks. Note its an internal wall so wont be exposed to rain and frost as external walls. Is the type N mix adequate or too strong for such old bricks. Is there any way to identify what the old mortar mix was?
Any advice appreciated.
