Not done a D&D before, always done S&C and skim for the last 25 yrs, but have a job where this isn't practicle. Do I need to unibond the wall first, it's old hand made bricks that suck for ever and worried it will dry the adhesive out. Tried looking online, some say yes, BG don't mention it, other than damp the substrate if dusty/porus.
Any tips, advice appreciate.
