WaterShield needs a porous surface in order to work. As most bonded stone is non-porous that feels like a "no" - but you could test to see if your statue is porous enough to take on this treatment.EXT Exterior Polyureseal Clear *might* work if the stone has enough grit for this topical coat to grab onto. In either case, we and the manufacturer VERY STRONGLY advise you to test with a sample of the product to make sure it adheres well and you like the final appearance. You are in uncharted territory here, good luck.EXT and WaterShield should not be used together, you should choose one or the other. EXT gives a topical layer finish (like plastic) and the WaterShield will not change the sheen at all.
