I purchased an A-25 airless foam wand from Lafferty Systems. It works okay with my FatBoy Bandit. Not sure how it would be with the SWS skid, probably better. For my system I may need to add Roof Snot in addition to GW to get a foam that would hang good on vinyl fencing or a 12/12 pitch.

The A-25 airless foam wand is designed for low pressure systems.  I had them put a 1/4 in male QC on it so I can use it interchangeably with my 4-Banger.

I have been specking out the best way to create foam over the past year.

We use a CAFS system in the fire service to create foam. Compressed Air

Foam System. I have found the ideal components to build a small CAFS system.

I just need to spend time on prototype.

To create a "Good" foam you need the following:

* A foam concentrate

* An inductor/injector

* Mechanical agitation (air)

The problem with an induction type system is the inducor needs to match the 

nozzle and it will create a foam good enough for roof cleaning, but it will not

spray a thick foam high enough to wash the walls of a two story home.

I have been looking because I want to pull up to a house wash, foam it "great

attention grabber" and rinse. A foam blanket will help keep the chems on the wall

longer in the hot sun as well.

Gotta run, there is a deer in the woods with my name on it.

Here is a video foaming a vertical surface.

I am not recommending the company in the video, just showing 

the concept for foaming vertical surfaces. Now imagine foaming

an entire house for a house wash. You would get EVERYONES attention

in the neighborhood.

AC, is there any problem adding Roof Snot ( ammonyx lo or ammonyx M) to the greenwash mix to try to generate more foaming action with my A-25?  Don't want to cause some sort of cynergism!!

 I cant speak specifically to the chemestry or toxic of mixing the two....though NO issues have been had. However I can not make Green Wash FOAM much because of keeping it biodegradable in nature. If you need the FOAM and cling I would bless Russ with the business.

1. Because he is a GOOD guy.
2. Because the reviews of Roof Snot of other reputable people has been very good.

I ordered some from the good man yesterday.  I'd like to try it on brick walls to really get some "hang-time" and eat away at the black GC.  

Just so you know, I do get a bit more foam generation with the A-25 using just the Green Wash.

Hello,

Could you let me know how long the Roof Snot "foam" actually remains visible on the roof once applied?  I am thinking of adding to my augmented CH/ SH/GW  mix and trying Roof Snot to minimize run off.

Will this work using a SWS setup or do you need a airless foamer?

Thanks in advance

 Jeff,

As we are teaching proper spraying techniques around the US we are seeing many pros applying TOO MUCH chemical to the roofs. If you are using correct application techniques there should be little or no run-off from the roof. A foaming surfactant should not be needed.

AC & Tim, Thanks for the replies and helpful info. It was more of a "what else can I add to the tool bag" question and gleaming from the experts after reading previous posts. I am always honing the techniques as learned and applying them the best I can.

No major run off issues yet "knock on wood".

Again thanks to all !!
