1 I emailed them today and got the same response that they are still transitioning the SLP program to the Fischler college so it will take more time to send acceptance letters. 2  I wanted to start Fall 2015, but I have no idea when I can start now.
Second, Ditra is a decoupler, meaning (in this case) there's no chemical bond between the tile and the subfloor. With cementboard, the tile is mortared to the cementboard and the cementboard is mortared to the substrate, so there's a chemical bond. proprietary product created by Schluter Systems, Ditra is a polyethylene decoupling membrane designed to manage movement in wood and many other types of floor systems to prevent cracking and other problems with tile installations.
Don't use Ditra-overkill on basement floor-fracture guard can be laid on your mastic. Thinset can be laid on the fracture guard (I have used this product but no affiliation with company) and then you tile (don't do ceramic).
