hello there , was wondering if anyone could advise me on mix ratio for lime render and what sand . ie leighton or sharp, with nhl 3.5, worried about shrinkage as it on soft brick with lime motar . thanks
We don't use Hydraulic lime for external render, we used putty based mortar with porcelain clay (argical)as a pozzolan just get it ready mixed in crates and put the pozzy in yourself 8:1
The windows getting tight for external lime work now tbh.
