I see many have said they use a paint brush to apply the Sta-Flo in a 1-1 solution. Is it to thick to use in a sprayer at that dilution?
It may depend on your sprayer. I think this dilution would be too heavy for me to use in a hand sprayer (my hand would get tired), but I see others use it in a sprayer. When I use the brush, I give the fabric a couple of minutes to absorb the starch solution. Seems to me a heavy solution like this might lie on top of the fabric longer (especially if fabric has not already been prewashed), making it slower to use at the ironing board.
