How to renovate the exterior brick wall?

Question

my house's exterior wall looks very old. Bricks are still in good condition. Only the mortar between the bricks is not good. someone is missing.

How can I renovate the brick wall? Can I just fill mortar in it? or something else?

Answer 1

Tuck-pointing is a very tedious job and usually left to the experts....
depending on the required joint finish it can take months to do a single average dwelling....for one person...
mortar is prepared by removing all loose and cracked bulk, pressure cleaning with a high pressure water blaster is also recommended so as to remove any lichen and or fungi growth etc. ...acid cleaning with a mid strength HCL acid solution is also helpful if pressure blaster is not available....
If you are inexperienced with using mortar and in tuck-pointing then I suggest that you try an inconspicuous area to practise/try out first as if you stuff it up it can be quite an eye-sore.....
mortar is 4 fine brickies sand, 1 cement, 1 fire clay, bi col or other plasticiser to water at recommended rate, add coloured oxide at trialed strength to each mix exactly the same quantity & brand throughout the entire job or the color will differ.....
Practice getting the mix right before starting the job for real....
the mix must be " plastic " or you will have it falling out on you...
a grouting gun can be used but the old method was to use a angled straight-edge to slide the mortar into the joint with a pointing trowel.....
when you get sick of it .... call a pro....

Alternately you could " Bag " or render the walls with a coloured render..... more materials... less time and expertise ...

Chisel or grind the degraded mortar back. Use the equivalent of a pastry bag to squeeze some into large gaps. Re point the edges between bricks with a narrow trowel. Adding colour to the mortar is as simple as mixing in some pigments (see any good building centre).

Answer 3

Repairing the mortar is called tuckpointing. There are colored dyes that can be added to the mortar to get different colors. Good luck.
