I have had this happen. My best guess is that my surface cleaner uses pressure to remove dirt and mold on the concrete but there is a fine line between removing what you want and taking a smal bit of the concrete top surface at the same time. The streaks are caused by the fact that your overlap is an area where the top surface of the concrete has been blasted twice. Take a look at it with a magnifying glass and will see that a slight bit more of the concrete has been removed in the overlap areas and leads to a streaked appearance. I have a 4.8 GPM machine driving my WW Classic. It came standard with 2520 nozzles. I changed to 2525 nozzles and the streaking was diminished but on some "softer" concrete it reappears. Was thinking of going to 2530 nozzles to see if I can reduce the streaking even more yet still get the mold, dirt and mildew up. Doesn't happen on all driveways. just the "soft" (for lack of a better term) ones.

Sorry, I don't have any newsletters to share with you but was looking at your website which is very nice. Can you tell me what you use for the wax you apply and how you apply it? In order not to threadjack you can PM me if you like.

I have great results on stucco be it real or Dryvit using a 50/50 mix of Sunbrite citrus and 12.5% SH (bleach, chlorine, pool shock, its all the same). If it is really nasty I will up the percentage of SH to close to 2:1 with the Citrus cleaner. Let it dwell for about 10 minutes and a low pressure rinse off will have the crap just flooding down the sides of the house. Just don't let it dry. That all being said I would listen to Ken as he is a seasoned pro and I am just in my first real year. Good luck. PS Sunbrite Citrus contains Sodium Metasilicate

Well, I guess I was once before with my little machine but I went to x-jetting for awhile to get more chem on and when I got my new big rig it didn't have it plumbed in. With some help from Bob I plumbed in an injector and had a 15 foot piece of hose with a screen on the end that I would put in buckets. My rig came with a 225 gallon fresh water tank and a 35 gallon chemical tank that was plumbed to a sureflo as the guy I bought it from used to do roofs in Florida. I played around with it for awhile and decided that roofs were not going to be a service I offered until I had employees so I started filling the chem tank with housewash and dropping the downstream injector hose into the top of it which was kinda a pain. I always forgot to rinse my injector out after finishing and 15 foot of hose with housewash on it was slippery and required rubber gloves to hang back up. Today I decided to replumb the rig and change the chem tank outlet from feeding the shurflo to feeding the DS injector. The surflo now has a 6 foot section that I can drop into a bucket of oxalic, which is what I use it for anyways, and now have a tidy solution with the injector. Turn the yellow handle one way and the injector gets house wash. Turn it the other way and it flushes with fresh water from the 225 gallon tank. No more buckets of housewash and no more injector hose wrangling at the end of the job. You pros probably already have it set up like this but I am happy to finally make the switch to this. Will save time and effort and the injector should last longer with a nice fresh rinse after every job. Here is a pic......

Thanks gang. I just need to give the rig a wash now. Getting a little dirtly with me tromping all over it making changes. Love this business. Can't wait to get to the next job.

Actually most illegal aliens use Social Security numbers obtained fraudulently and do pay taxes. The employers just don't check on em because it is better to not ask questions and get the cheap labor. It is estimated that the taxes illegal aliens pay are in the several billions of dollars and they will never be able to reap the benfits of Soc Sec and other programs. And you wonder why many politicians don't persue the "get em out of here now" mentality? Read the above as they realize that those billions would all dissapear. Just the facts.

hey Jeff that is great, both my sons (age 4 and 5) take Karate and they love it, My oldest practices his kata at home and is very good in class. My youngest gets distracted but is really starting to learn now. Great exercise and the instructor is good on the discipline stuff. Congrats on your future black belt! Keth

Interesting. The average consumer may actually like the look of that picture where they apparently took a turbo nozzle to a fence but when they get a close look at the fur that is thicker than a Brown Bear they will wonder what happened. Yikes!

Ohhhhhh. Ahhhhhh. Great hand job! :lgsideway

Thanks to all. Found it in the Auto section at Wal-Mart for $4.67 gallon. I have a friend who is trying to sell a vacant house and has some serious oil stains in the driveway. Gonna run some tests on Friday. Thursday is booked solid. Cheers.

John, Those boxes are a piece of cake for any competent welder. Just find a local welder and they can put one on and weld it to the tounge as well. Very secure.

Between 5 and 8 cents a square foot. If it hasn't been done in awhile try charging 10 cents for the first clean and then between 5-7 for the monthly. Around here there are guys that quote stuff that is around 3 cents. I do the easy ones for 5 and the tough ones for 8. Can't get anymore than that.

Thanks Christopher. I will pick some up. Have to wash the truck tonight because the logos go on tomorrow. Cheers.

I always hear about this Purple Power stuff but have no clue what it looks like in the store. Where would I find it at Wal-Mart?

Jeff, I agree with you 100%. Six years of horror and the right-wing is still blaming the Democrats. Even that **** sissy Anne Coulter can't stop talking about Monica Lewinsky. Get over it. The Repubs have been in charge for six years and the world is worse off because of it. Had enough? Vote for change.

Truly tragic. I constantly remind my kids that the garage is off limits and that they are never to go in there without an adult. Luckily they listen and I have all of the bad stuff on a high shelf and the 55ers have the bungs replaced each time. Could never imagine the pain of one of my kids dying before me. I feel for the family. Keth

I would try one side of the house again making sure to apply chem from the bottom up. I had a real hot wall streak a little due to it being a dark color and a tall wall. Was able to get the streaks out with another application. On walls that are getting beat by the sun I now rinse them with fresh water first to get the heat out of it so that this won't happen. Good luck.

Looks great. Since none of the things in your, or my, housewash is particularly viscous you can't expect it to cling like glue. It is a thin liquid and it will run down the wall. As long as it is wet and stays wet for the whole dwell you are fine. I had one today that I didn't make my mix strong enough. Had to apply twice to a lot of mildewed fascia. Pain in the ass. Forgot my "booster bottle" to kick it up a notch. Won't do that again.

This from the PressureTek site...... X-Jet or M-Jet: 2 Gallons 12.5% chlorine, 3 gallons water & 10oz of Simple Cherry.

And from someone who posted recently that he has been doing exterior staining for "six months". Needs to learn a bit of diplomacy in my opinion.

I am using the Sunbrite Citrus and have done two stucco with it. Actually one stucco and one drvit and had good results. Mixed 50/50 with 12% SH and downstreamed around 15% and the dirt just falls out of all the nooks and crannys.

Great job Ken! Was the big streak down the chimmney from something other than algae? Looks more like the stuff you get on gutters from asphalt shingles. If a strong SH solution took that all off I am very impressed.

I think the recommendation was to use Tide in conjunction with a Vseal product but please let us know how it works! The few tough oil stains I have had in concrete I have always told the owner there will be a shadow that will fade over time but not to expect miracles. Once the really nasty stuff is gone they seem happy enough once their expectations have been tempered. The next really tough one I get I will try what Vseal suggests and see what happens.

I have a chemist friend who jokes.... "The solution to pollution is dilution!"

I Couldn't Have Said It Any Better Meself. Listen To Ken.
