I have just cut out a space in a dissused chimeny breast in my flat, i intend to use the space as a computer cupboard. i want to expose the brickwork on the outside of the cavity, the interior will have to be rendered as its in dire states.
Now to the point. The morter between the brick is basically just a yellow colour dust! what sort of morter should i use when re pointing and replacing bricks?
also wht shoud i use to seal up the exposed brick after i've repaired it all?
thank for your advice.
