Power Washing and Roof Cleaning Forum

Nick, is that a house wash mix?
On a standard asphalt roof we use 30% SH.
If it is for a roof. What type of roof is it?
1% ammonyx should be sufficient. It wont really get thicker using more.
You might need to apply less juice and just keep all areas wet but not so
Much that you have a Lot of run off.

For roofs, alot of guys are going to disagree... 4 cap fulls of roof snot per 5 gallons.

For houses we use power house from sunbrite. We dont use as much as they recommend either!

I am looking for some assistance with getting my mix right.

 

I am using 10% SH and adding a masking agent which is lemon scented. I am also using a Ammonyx Lo as a base surfactant but feel the mix is still too liquid as I am seeing a lot of run off when applying to roofs. Ideally I would like it to be a bit thicker and sit and stick a bit more.

 

I am adding 2% by volume but think I might need a bit more.

 

Any advice greatly appreciated. Can anyone give me an indication by % as to what they are adding.

 

Thanks

2% should be more than adequate.  Practice with different application techniques and give your mix time to creep down the roof.  Perhaps try coating the bottom portion of the roof first, minimizing run off.  Then treat at the ridge over and over, allowing it to run only to where the top of the first application was.  Our foreman insists that he saves a lot more roof mix by doing it that way.  You'll find out what works for you, but it sounds like you're using PLENTY of surfactant.  Keep us posted on what works best and good luck!

Pssst - ensure that you put than run off to good use somewhere too.

 

Nick, as you can see surfactant use is all over the place. I don't think there is a "one size fits all" ratio for it.

On greenwash we use 64 OZ per 100 gallon for house mix, 64 per 50 Gallon for roof. Everything else is "cut to fit". Trial and error is the best thing i can recommend.

Thanks for the feedback. I get that its a feel thing and that every situation requires its own consideration.

In saying that the average seems to be about 1% for roof and .5% for House wash. If I have my numbers right.

We do use metric here so there are conversions that are required .

Can anyone advise how much solution would be applied to a 21 Degree pitch cement tile roof that is 2000 sq feet. Obviously there are many factors to consider and variables but just looking for a rule of thumb so I can gauge what I am doing.

Thanks again.
