Modified vs Unmodified Thinsets
What is the difference between modified
thinsets? When should you use a modified
thinset? Is a modified
thinset for all floors and substrates? Does a modified
thinset already have the additive added to the mix already? Does a unmodified
thinset need additive and how much? Can it be half and half? And what about Superflex is that modified
and does it really flex like the name implies? Or Versa Bond is that good for just about everything?
