Roughcasting over painted stone work(advise)

[frankie porter]

Hi lads I am roughcasting over stone work that is painted shortly and am fixing metal lath to the structure before applying materials . my plan was to fix lath directly onto painted stone work and then apply base coat etc. But my mind says I should prime the walls first then fix lath to structure . Any body on here dealt with rendering this kind of building before ? Would it be fine without a coat of primer ? Any advise appreciated thanks in advance

Going to prime it any way kills any suction and will give it an extra bit of adhesion !

Why can't you use a Parex printer as a tight base coat with alkaline mesh, then a top coat of pre bagged render.that way you don't need to bother with the time and expense of fixing stainless steel eml.
