DRYPACK, A lot of people, contractors designers still don't know how, when and where to use drypack.
It has been used for hundred of years and it's a dying trade.The young generation tile installers and contractors are not seeing this application because they are not working with the big companies.
Companies that work on big building, swimming pools etc, All over the world this is being used, Everybody in USA and Canada see the cheap mesh and scratch coat method and think that's is a goodway. No way! Builders don't care how long your tiles last, as you see when you buy a new house and live there a bit, tiles start to crack, why because they use cheap floormix just to save money, yes it' all about making money not giving you the write professional method of installation.
