I like e my dungeon with 8' high ceiling ( can go to 9.5' for an industrial look) . Tiles had been there for a while, still can't find efflorescence. I wouldn't change it now. Workmanship is remarkable. Pattern makes it is non - dungeon-y, grout is intact, looks like tiles were installed yesterday . I don't even bother to use spinner for cleaning, hardwood floor machine does the magic.Unfortunately you’re right and leads to a major case of efflorescence.
We like to make general statements about anything and everything, but is there a slight possibility that heated ( non-heated) tiles&grout floor in full walk-out basement might be an exception to the rule?
As far as engineered crap goes, we ( consumer) are taking hit, since manufacturers are cutting ( almost seem like skipping) trial period and sending product straight to our houses) Definitely seems that way, I've seen case where splash proof laminate buckled up from a few drops of water( yes, water got in between seems of the planks and for sure there was no ongoing issue with moisture perspiring from subfloor. Unfortunately, this is no coincidence, this occurrence is more common than we like to think. We can argue ( sorry, discuss) the topic, but there are millions of customers who are living the nightmare. Rather than coming with excuses
( efflorescence and such) let's talk about craftsmanship
( workmanship ) instead .
