Can I add thin veneer to a painted foundation?

Can I add thin veneer to a painted foundation?

A customer writes:

“I’m hearing various answers from masons as to whether this product (Laticrete Hi-Bond) can be applied to a foundation that is painted.”

The answer directly from Laticrete:

The short answer is no it cannot. The paint would be acting as bond breaker. We only recommend installing stone with any of our adhesives to clean, free of paint, sealers and form release agents, sound concrete. In order for the adhesive to reach its intended strength it needs the open pores in the concrete to mechanically “lock” in.

If the wall is painted, the pores are clogged and the adhesive will not be able to bond to wall as it is designed to, and the installation may result in a failure.
