As an Ardex mitigation installer I am interested to know the particulars of the proposed installation.
I also sense the hesitation regarding MC Rapid.
It has been my experience that all MC systems work 100% of the time when the concrete is properly prepared and installation is properly done.
I have seen failures with MC Ultra due to installation errors and improper preparation. MC Ultra requires many more steps to install, and each step has to be perfectly executed to perform properly.
What I am saying is the gambling isn't happening when you choose the system to be used....
The real gamble is choosing the installer!
And yes, I have seen Level Master Elite failures too many times to count.
The product is sound but proper installation is the key to performance.
