Parge coat over brick

[Mike Lamb]

How long should a good parge coat over brick last? Is it best to attach metal lath? Is there a recommended authoritative source for this application?

Just noticed this question,

That's a nice looking parge job!

IMHO, if the surface was properly prepared (cleaned and sufficiently damp almost but not quite to saturation) and the work was properly cured (kept damp for about three or four days), the parging should last for a very long time. Lath should not be needed when applied directly on masonry unless the surface the parging is applied to is not porous enough (tile, painted, etc.). The raked joints of the brickwork should permit the parging to key into the brickwork nicely.
