I on occasion did spray cement just to see how much was covered if I did total coverage. Tried to copy the pattern.. are you saying to perhaps make the mix more concentrate?A 5 hp skid sprayer might put down 2 gallons per 1000 sqft.
A back pack would probably apply closer to a half gallon per thousand sqft. Try it with water on concrete to find the correct gallons per thousand output. Then mix according to the area covered, not gallons in sprayer.

That's good. Thanks.Vikings
No what Riggles is trying to tell you is CALIBRATE your sprayer. First measure a section on cement that is at least 1,000 sq ft. Then spray that section with straight water like you would a Lawn. Now measure to see how much water water is left and subtract that from your starting amount. The difference is how much water you applied to the 1000 sq ft of cement. Use that rate to mix the herbicide and spray a lawn. To be extra safe you might want to use the lowest rate on the label to start with.
Very cool here at night, even had frost a couple nights ago.And make sure you use this same spray density when even spot spraying. It is easy to be tempted to "soak" areas down to "make sure" you got them.
As far as the die down, I don't know if I would be too concerned yet or not. I don't know what kind of temps you've been having up there, but these will definitely affect the time of curl and burn down. Here, it has been rather cool. We've had daytime temps in the 60's, 70's and a only couple of days in the 80's. Our night time temps have been in the 50' and 60's, and even as low as into the 40's. Our kill time is extremely slow right now. we are keeping a close eye on them, and they ARE dying, but they are slow to go. So, on that basis, don't be too discouraged yet...especially only a day after. If we were seing consistent temps in the 80's, it would be a different story.
