Unfortunately this human resource policy injustice isn't limited to just SW. It's the cold hard reality of capitalism. That's why I have a bachelor's degree in business. So I can knock off some over paid lifer at SW someday. If I'm lucky I might get the high stress job of sales rep. Who knows.
It's also why I started my own business. But again, why should I help them?
FYI the data sheets for all of the Kem Aqua products can be looked up online and downloaded. That would give you a good starting point. But it will take a lot of trial and error without having someone who has used it or a sales rep who has seen it used and has input from his customers on using it to give you an accurate answer. Unfortunately again, those people are usually ousted from SW because the make too much money.
If you call the OEM coatings division 1-800 number you can get a tech who knows the product. They don't have a prompt for this at that number.
I think I pressed the option for sales and the first person to answer i explained i called the resdiential technical # first but they couldnt help me. You need the SW product number off the tds for them to help.
The guy I was transfered to was short and obviously must not deal with customers on the regular but he seemed to know the chemistry of the product and did answer my question. Granted the answer I was given was "off the record" regarding the ka+ pigmented surfacer.
But to me there is the official tds recommendations printed for liability and warranty and then there are the off the record recommendations that aren't sanctioned but won't necessarily break the product but may be needed to make the product work.
