I've noticed in recent times that some of the grouts I use seem to suddenly have a tendency to dry patchy or suffer from efflorescence. I try not to use Granfix on anything in a dark colour but now it seems to be happening with Mapei.
I use a washboy but it didn't cause any problems in the past.
Has anybody else noticed this 'trend' or should I not use the washboy anymore.
Could anybody recommend an alternative brand where this doesn't happen.
