I have a full room height vertical crack in a conc. block inner leaf that I may stitch with helical rods, it has a sand/cement render & skim.
What width mesh (expamet) would I put over the crack before new render (and skim)?
Presumably this wouldn't need to be stainless mesh as it's not external?
Would I use a scratch coat then another render coat and skim?
What mix render?
Neat or dilute pva? Before each layer? Wait until tacky, then apply?
