Flatwork Demo Pics

I did a demo for a local store on one of their pumps and the results are decent from what I feel. Any opinions or advice on how to get the stains to clear up a little more. I DS caustic ;) (hot mix, 1gallon water, 5 cups of caustic), hot water, dwell time of about 10 min due to traffic at this store. I also went back over the area again with a wand in bad areas to brighten them up even more. Suggestions also the last pic is a different pump but just as dirty as the one before I cleaned it

I think it looks pretty good. I think a longer dwell time would have helped, maybe.
Compared to them having one of the employees do it with a cold water machine and a 0 deg. tip......it looks great.
 
I actually took my mix of caustic after i went over it with the surface cleaner and then poured the mixture on top of the bad areas and let it set for a few then hit the spots with a wand to take as much out as possible

What do you call a cup? I usually only put 12 oz/gal if I x-jet it on. That mix sounds really hot. Just curious how may ounces per gallon that is.

A couple of tricks to get the spots up... ( Cat Liter , Clean it with Purple Power and then etch it with a little Muratic Acid.. , Get you some 5 degree tips to get that Bubble Gum Up.. 15 Degree Tips on the surface cleaner and walk really really slow..
 
I took these pictures just before removing that last couple of gum spots, I thought about kitty litter and decided that for a demo that would not be a good idea to leave it sitting there after im gone.


Russ Call me , 601-383-1034 i have left a message on the 888 number but realize that your not at the office.


1 cup (8 oz) normal kitchen measuring device, LOL just busting your chops, the term cup could be taken several ways, meaning a Wendys Large Cup or a Sonic Rt.44 cup so yes the need to clarify was there. I also DS this on so my final ratio is a little different than the x jet but yes it was a hot mix.
 
Suggestion – When doing a demo do not do complete areas. The 2nd picture shows the contrast with the expansion joint of the slab in-between.

When you demo do incomplete areas (not joint to joint) the demo shows with no doubt the difference made.

Years ago I tested the side of a bank building. We cleaned a strip all the way up the side (3 story building). You could see the stripe a block away! I remember afterward thinking that somebody is going to clean that building even if just to get rid of the stripe! By the way I got the job. :)

That looks like a good product but it seems like you use alot for the amount of stain it treats. It doesn't appear to be cost effective for everyday oil stains like drive thrus.



It does look like a lot of product use Greg, but that looked like about 1/4 to 1/2 quart of oil in the concrete initially, they may have used less if they had hot water wash first and then apply there product to the dried surface.


The removal of deep absorbed hydrocarbons form concrete is interesting.

From early days to now .......water, to pressurized water, to heated water/steam (some say 200 others 300 degrees), add detergents ??????

what???? non-butyl, butyl, natural cleaners {orange etc}, caustics or combination of each.

But what does that lead too, partial removal?,........ ok good removal??, but the hydrocarbon is still in it physical form with mechanical agitation, when cleaning chemicals (detergent) are used the hydrocarbons are locked or partially locked chemically with the detergent, it is not really denatured. My POTW has small issue with this for fuel pad cleaning.


But Microbes, enzymes, bacteria,................ interesting stuff. (Remediation)

Then what about flocc/polymers????? (is this the ultimate lock?????? for the hydrocarbon and detergent)

Overthinking.....again...lol
