Bricklaying & Repointing

Pointing internal wall

Anonymous user 03/03/2024 - 3.04 PM

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. Any advice appreciated.

Are you a tradesperson and able to answer this question?

Alex from ADR is right, it will be lime mortar. You can buy it from most builders merchants now but may have to order it. Do not get hydrated lime, only natural hydraulic. It comes in bags like cement or in tubs in a putty form that is more expensive (used for fine work like axed arches etc). Mix it up at 3 parts washed sand and 1 part lime. Brush all the lose out and moist the joints with a plant sprayer. Good luck Paul
