Mud Bed Repair
Hi all, I have a large mud bed I have put down for a sauna tile floor. This is the first time I've done a mud bed, and I went with Laticrete 209 Floor Mud, mixed to the recommended ratio (plus a little more water). I had to use screed boards to help with keeping consistency of the slope to the drain in the middle, but I am seeing that there's some crumbling/divots where I filled mud in after removing the boards (even though everything was still wet), so I am using a 20-grit stone to grind down high spots, but I need to know what to do with the dips/divots where mud had crumbled and I vacuumed out. What would be the best way to go about evening out these imperfections to create a good bonding surface for Hydro Ban Liquid Membrane?


The bathroom is an upstairs, stick framed track home with 3/4" plywood subflooring.
