Testing the Mix and Application

Guest

Way to go! Practicing will be the best way for you to learn what and what not to do when cleaning a roof. Now go get you a 12V pump to help speed up the process.

Did a little testing today. This was my first attempt as roof cleaning. I don't have my equipment yet so I used a garden pump sprayer and also the SH was labeled 10%, so maybe a little weaker than the 12.5% label. I tested 65/35 (H20/SH), 60/40, 55/45 & 50/50 in 1 gallon and 1/2 gallon batches. I also added 0.30 OZ Am Lo. Quite a learning experience! It seems that it's a combo of coverage and mix %. I also did a little rinsing, but I learned VERY quickly that rinsing will be time consuming and a hassle. Dead algae streaks were prevalent on the areas that I spread the mix too thin. The roof was a 19 year ELK Prestique I Weathered Wood 8/12 pitch that I'm reroofing next week, so it was a great test roof. I offered to clean the roof instead of replacing it, but the homeowner opted for replacement.

I started out trying a pump up garden sprayer back in 1990.

It is just not enough flow to saturate an area and keep it wet long enough.

You need a 12 volt pump etc like we use.

Then you can practice with SH strengths and Ammonyx Lo and get your ratios adjusted.

If your SH is fairly fresh, you shouldn't need over 35% on shingles.

That is what I figured. I've read on this forum to leave the garden pump sprayer at home, but I just wanted to give it a try because it was a perfect roof to test due to its replacement this week. I'm going with a 3/8" All Flo, air system. I should have all of the stuff next week. Received shipment of the Eaton 6 1/2 hp 14 cfm compressor today, got the cargo trailer last week and PWP is shipping the pump/hoses/reel later this week. Talked to a bulk SH company today. They are Poolsure They have offices in Texas and Florida. Has anyone done business with them?

Awesome pictures and way to test using the scientific principal!
