My boss has a "Home Made" above ground concrete pool. When he made the pool, to finish the inside he troweled on the walls and floor some mortar or stucco stuff. This stuff was put on in two applications and was lifting and cracking in spots to where it was coming off the bottom of the pool. We have drained the pool and are in the midst of removing this stuff. My question is , this stuff isnt coming up very easy and I was wondering is there anyway to remove it easier? Someone had told my boss to get some muriatic acid and pour it on it and that would lift it up. If this is not the way to go about doing it does anyone have any suggestions ?
If the acid is the way to go can we walk in this stuff to scrap the bottom of the pool ?
