What was your exact mix? What was the pitch of the roof?

Fill out your signature please so we know who you are and where you are from.

I promise if you're buying from Univar by Hobby its not very hot Sh. You'll need to bump your mix up. Ive been buying from them for 3 years. On a 12/12 2500sqft house here in Houston 80gl isnt un-heard of.

You were saying both houses combined were 5500 sqft right? with practice you could use less im sure. And that mix you posted is only for 40 gallons. Do you just have a small tank and have to mix multiple times?

You're a little heavy on the alcohol and light on the dawn.

Did you use regular Ultra concentrated dawn?

For a 40 gallon mix I'd use no more than 64 oz. IPA

Double your dawn for a 12/12 pitch.

Try the new myristamine oxide.

myristamine oxide. How is that working for you? So you use about two quarts to 40 gallons of mix?

Personally, I can do two average homes on 100gal with enough left over to clean flat work as well. (adding a lil more water)

Thanks, I'll take some pics soon. I've never learned so much from one website. This is a great place, thanks again to everyone's contributions
