Hi David,
I purchased several cases of Stain Proof late last year and have been phasing it out of our projects. I don't know if the formulation changed or not, but ever since they switched to the new Acetone based product (which caused the problems you are describing) and then going back to the so called "original" formula I haven't been thrilled with the performance. We have had much better luck with STT SB and FE. We also have some of our own formulations that our perform (stain protection wise), I'm just unsure how long the protection lasts. Do you know if the 12 gallons you purchased were the acetone based (voc exempt) or the original alcohol based formula? We over apply stain proof on every job... it's part of their recommended application rate on the label. We have never darkened any stone with the formulation that we have used. The label recommends one quart per 20 to 250 sq ft depending on surface absorption. How many sq ft per gallon did you use? They recommend that you generously saturate the surface with Stain Proof. Did you wipe off the excess before it dried? The label does say it can lighten or darken some surfaces, but we really have never experienced it, only hear about it.
Keep me posted on what comes of this. I heard a blow torch is needed to remove it.
