Hello,

I know this isn't a pottery issue but I thought someone here might
know how/if crackle glaze -- in its application as a way to paint
walls -- can be painted over with regular latex house paint. I don't
want the latter to crack, i.e., I'd like the walls henceforth to just
look like normal flat painted walls.

I'm thinking this won't be possible, that to get what I want I'll have
to sand all the crackle glaze off, which is not my dream come true.

Internal or external walls?
