Cleanliness
The substrate needs to be clean and free of foreign matter: dirt, oil, grease, dust, moisture. These create a layer between the substrate and the membrane that prevent complete adhesion.

Thickness
For the membrane to be effective, it must be installed to the thickness specified by the manufacturer. To achieve these thicknesses oftentimes requires 3 to 4 coats. One layer is usually insufficient.
Good rule of thumb: If the substrate can be seen through the membrane, the membrane is too thin. Better yet, buy a tester and measure the membrane thickness to verify the minimum thickness has been achieved.
Traffic
The membrane must be cleaned of dirt, dust and debris that collects on top of it. Thinsets and mortars will not adhere to a dirty membrane.
When in doubt - READ THE INSTRUCTIONS!
