When an installation problem arises, fingers start pointing in all directions! This is what happens if you use one manufacturer’s thin-set and another manufacturer’s membrane and another manufacturer’s grout – everyone will point at the other as the problem’s source, or they may all point at you as the cause!
You can avoid being in that predicament by using single-source installation products; then there’s only one phone call to make if something goes wrong. Installation product manufacturers know that there’s less chance for problems to develop when their products are used together as a “system,” per their directions. Makes sense – manufacturers design their products to be compatible! That’s why they typically offer special extended warranties when their products are used together on jobs.
