We've used 40sk several times and know about the milky white residue... so far it hasn't been a problem. Glad to hear you solved your problem.
When we test Stain Proof we are getting surface wetting and coffee, and oil stains. How it it testing for you?

Stainproof has been alcohol based for some time now as the Marble Porcelain sealer changed to acetone base. I have never had a call of failure yet in 5 yrs.
I have resolved the problem of the darkening effects from Stainproof by bleaching twice and using Methylene Chloride in some areas.
The area 960 sq. ft. of exterior limestone in which I applied 2 1/2 gal of Stainproof to.
I returned the remaining of the 12 gal. and have tested another batch lot with no ill effects.
Drytreat has offered to send me two cases free of charge.
I hope other applicators don't have a major problem as I did. Very fruststating!
So far Drytreat has not admitted any fault of the product yet, just replacement and free sealer.

I hope you Know about SK 40 and it's problem turning surfaces white if applied in the sun where cloud covered or not?

If you have any questions, you can call me. 479-903-1412.

I have a major problem with Drytreat Stainproof that thought you might be aware of. The last batch of 12 gallons purchased 3 weeks ago have caused all stone and grout that I tested to darken. I found this out last week after applying to 1,000 sq ft of exterior limestone. I am work to resolve the color enhancing effects of this application.
Have you experianced this? If so, have you remedied this? Would you like to keep you posted?
I have a couple of chemicals that I tested this weekend that I will be trying tomorrow.
I've all ready passed communications to Stuart Anderson of Drytreat with me to blame for excessive application.
Even polished granite will darken, as well as any absorbant stone.
Please let me know your thoughts on this matter as my customer and architect are thinking of not letting me finish the remaining 5,000 sq ft pending the out come.
