Grouting Porcelain Tile Walls
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 &amp; 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.
