when bricklaying - what is bag rubbing?
Answers:
Bag rubbing! flush point the brickwork, then when semi dry rub it with a piece of hessian or similar until all surplus mortar has been removed, great for old brickwork as not only does it fill the joints it also cleans the bricks if done correctly. good luck.

Bag rubbing is a technique where the pointing of masonry is conducted in a manner closer to rendering, that does not extinguish the 'character' of the wall.
The joints of the masonry are prepared the same as for pointing, being cleaned out to an average depth of 25mm to form a key. This depth will vary according to the nature of the stonework, but should not be less than 20mm.
The joints should be thoroughly cleaned and washed out by use of a hose (fine spray nozzle only) or suitable pump up sprayer. This is best done the day before application and again, immediately before application.
