You will probably get many different opinions on this topic. Some people use
silica sand so they can flip the shelves over from firing to firing. Other
people kiln wash only one side of the shelf.

If your shelves do not warp, I would apply kiln wash to only one side of the
shelf and not flip it from firing to firing. Reapply kiln wash only when it
begins to flake or crack. You don't need to follow a set schedule for
reapplying kiln wash. If you are not sure about the condition of the
kiln-washed surface, shine a light across the shelf. A side light will
reveal all the surface imperfections.

If you apply kiln wash to both sides of the shelf, you run the risk of kiln
wash flaking off and falling onto the pieces below.

Wipe off excess kiln wash from the edges of shelves. Clumps of kiln wash can
fall off onto the pieces below or even into an element groove, burning out
an element.
