KoEster, with an extra E? We specified Koester “VAP I pH System” for remedial vapor control treatment on a concrete floor, and it worked well. I have had no other experience with the company, but will tell you that Koester was recommended by a high performance coatings rep in whom I place much trust, for what that is worth. ---

I’ll echo George’s comments. I’ve specified their “VAP I 2000” with good results. However, I don’t believe they offer a waterproofing material. ---

Thanks George & Ron, your input is most appreciated, the product is the VAP I 2000. ---

I’ll add a bit of advice that was given to me about using the product, or any similar product for vapor control: Apply it before the interior walls are constructed. It keeps the labor costs down by not having to work around the interior walls with the shot/sand blast preparation process, and it ensures a complete seal of the concrete surface. ---

Ron, the room to receive the product is existing trash room that is being converted to a refrigerated storage room, the primary walls are existing. ---
