I have built a fountain with a concrete slab base and cement block sides. So that is is completely water tight I have fiberglassed the interior. I would now like to attach some natural stone on the interior (1-2in in diameter) using thin set then overlay the entire fiberglass bottom with a 1/2 stucco layer.
My questions are these:
How does stucco perform being submerged in water.
Will the stucco and thin set adhere to the fiberglass well enough.
Thanks, Wayne Gregori
