Anthony,
 
Just saw the pics and did not realize it was an outdoor stone. In a nut shell I would not use an impregnator on an exterior stone for several reasons
 
First it is very difficult to get it dry
second you may block moisture from escaping from behind the stone
 
there are exceptions to this rule and there are sealers that are designed for exterior stone

If the sealer is turning white it sounds like a reaction with the polymer and moisture. This is quite common with many sealers. You are going to be hard pressed to get them to tell you that something is wrong with their product.  I would ask the following questions
 
1. Does your sealer contain any polymers or resins that are moisture sensitive during applications
 
2. What is the Vapor emission rate with your sealer
 
Ask to talk to George O Regan over there..he is a good friend and stright shooter.

I have a situation where an enhancer has turned completely white on the surface of the stone.  Does anyone know if the Stone tech Enhancer pro truly allows the stone to breath once sealed? Seems to me that it might not.  Dr, what are the correct terms I need to use to ask Stone Tech Dupont to find out about its breathability.  Unfortunately I am in a legal battle now with them and I need to word everything perfectly.
