Hi,
I had my pool replastered. The new coat went on top of two existing coats. The contractor cut under tiles and pipe fittings, applied bond coat and then new plaster on top. He said he checked all existing plaster and it was in good shape (no delimitation/hollow).
I read conflicting opinions, some say that two existing layers is too much, and full chip out would significantly increase the cost and potentially a risk of damaging gunnite
