I remember a guy 15 years ago made a video of that

I know it sounded like a noobie question, and really I knew how to remove gum... But I guess I was really trying to find out if it was reversable if we ever bid a previously etched job... and give the absolute no-no's in my training manual.
I learned about the variable pressure wands when I first started, and it has been the best thing since sliced bread!!
Sorry for the redundance in noobie questions. It has greatly helped me to systematically train my employee's. Without PWI, what would life even be? lol

I would screw stuff up if I didn't have my variable pressure wand. I've used them since the 1st day I went into business lol.
Another thing to remember is that if the concrete is already etched before you start the work make sure you take before pictures and have the PM sign a holds harmless agreement.
Sell on routine maintenance. I tell customers that there are chemicals that will take the shadowing out after the gum is removed but routine maintenance and sunlight works best.
Remember the actual gum doesn't cause the shadowing or stain after the gum is removed it's the acid in your mouth after you spit the gum or drop the gum that actually creates it.

try lowering your pressure

Okay, going to show my ignorance once again...
How does the variable pressure wand work? Does it simply reduce/increase water flow? If so, I would think that it would have a negative impact of cleaning power?
I thought the variable pressure wand was a gimmik. If not, and you guys seriously recommend it, I will look into getting one.

Dave, no gimmick! That is all we use mainly. We have others but you definitely need a variable wand. Lowering pressure is needed in many circumstances and gum removal is one of them. Also for rinsing sometimes, house washing, etc...
Get a variable wand for sure! I'll let the tech gurus explain the science behind how it works.

Dave I copied and pasted this from another thread that I posted in about this subject earlier this year.. hope it helps. Here is the link to the thread too. http://www.propowerwash.com/board/u...788-Dual-Lance-Wand&highlight=adjustable+wand
Dual Lance
I'll speak from how we use it for house washing and sidewalk cleaning as:
First off, a dual lance is designed to draw your chemical from a bucket (or Chem tank) when you are downstreaming. When you turn the grip down it lowers the pressure so that the chemical injector can draw the chemical from your bucket. This saves a little time in not having to change tips.
We never use the the dual lance for down streaming, we use it for edging out concrete areas like driveways, sidewalks. When we do this we do not have a chemical injector hooked up. So when we lower the pressure using the grip, we are able to "control" our pressure and lower it, which allows us to get closer to the surface and clean, with out blowing mud, mulch, rocks, etc all over the place.
We also do this for brick surfaces, stone, block, and others, that are badly stained and have not been cleaned in a long time. With a higher volume (gpm) machine you can get closer to the brick and "flush" the stains out as opposed to using "pressure" to clean and risk blowing the mortar joints out or damaging the brick It's just another great way to Soft Wash brick and other hard porous surfaces. (note: I never recommend using any pressure on Stucco or EIFS,) A Dual Lance is also great for removing graffiti as you can control the amount of pressure you are using.
You can also achieve the above without a dual lance and use a ball valve, and turn the ball valve down, but you really need experience doing it this way so you don't choke your machine and cause damage to it.
We also use them for removing gum from concrete as, once, again, we can control the pressure right from the gun and being able to control the pressure almost immediately, helps in preventing damage.
They are also great for removing dirt daubers from brick as again, you can cut the pressure down, and get right up to the surface and "flush" all the stain out.
Toni, I know your a visual person, so here are a couple pics. One is showing one of the guy's that attended my school edging out a driveway,(notice he stands in the grass to do it) couple more of me using the dual lance around window sills and inside the patio are that a lot of dirt daubers. Another is of me showing another student how to clean brick. In that one we are using a low pressure tip and using the ball valve to control pressure.
There lot's of great uses for these dual lances, once you start using one you'll love it.
Hope this helps.

1) Yes sometimes. Mainly it's just another tool in the tool bag, and comes in handy for so many different application.
2) I get mine locally here, it's the MTM brand i think. You can get the Suttners from Russ or Paul. A lot of guys use those.
