Final 1-2 coats recommended thin compressive coats applied with Muddskip mixed into a lightweight joint compound for best results.

Midweight and Muddskip works well for all coats as a general application.
All purpose is recommended no further than the bed, block, or fill coat.

We don’t recommend sanding with anything less than 150 on a power sander for best results higher grit (example 220 to 320).
