Before you apply coating to a kiln lid, does the old coating have to be sanded off? And how long does the new lid coating last?
If the old coating is loose, then it must be sanded off before applying the new coating. Loose coating looks like the network of cracks in a dried mud puddle. These cracks form when the coating is too thick. The lid coating lasts for several years.
