When I am applying the grout to the tile walls, most of the grout just falls off the wall and the float while I am trying to apply it. I am using a pre-mix grout, so the consistency is right. What am I doing wrong?

The grout should be a creamy peanut butter, so you may need to mix in like 2 tablespoons of water to a full or new gallon bucket. These can sit around for years before you get it & can dry out somewhat. You want your squeegee trowel to be mostly flat against the wall to smear the grout on, instead of possibly trying to just stuff the joints.

    I agree with @Iggy about adding a bit more water. Let the grout slake for 10 minutes then see if more water is needed. You should stuff the joints; pack them full with the edge of your float, then finish with the float held at a 45° angle for uniform grout depth. Sometimes it helps to mist the joints damp with a spray bottle prior to grout application. Commented Mar 24, 2016 at 2:06
