I used calcium hypochlorite successfully to treat lichen a while ago but the dreaded black spots are now back. In between, I've had the cement mortar replaced with "sweep in" resin. Using the Paving Expert method, is it safe to use the same stuff or will it damage the resin mortar?

Never had a problem with resin mortars & the hypo mix.
