Concrete Stain Removal

Hi everyone! I have a two part question for all of you.

First: I have a major job to do in San Francisco, Ca. The total concrete measure for the job was over 38,000 square feet. The concrete is only one year old and it has some gum and a little bit of oil where they keep their trash receptacles. Could someone please tell me what type of acid cleaner I can use to get rid of most of the stain after removing the gum and the oil from the grounds. These is a primary concern to the property manager, so I really want to do a good job. They basically want me do clean all of the bad spots on the complex grounds.

Second: Most of the concrete is pretty much clean already, besides the gum and oil of the premises. Would someone have some sort of idea of to how much I should charge for this type of job. This job will bring me lots of other referrals as well.


Thank you,

Keith Richardson

you are allready looking at e-spec wash units, why not try there MR. MUSCLE for the cement work?
You should have hot water and im pretty sure in CA you MUST have water reclaim to use any chem.
You need to talk to JON and pick his brain.
 
Thanks for reply

Thanks for the reply! I have a unit and method to reclaim the water but my primary concern was the stain after removing the gum and oil.:)

Thanks,

Coastal, why did'nt i think of that? oh yea i did. lol what, you dont like to read my posts?
 
I have tried DR-60 from Delco on concerete and it works pertty good and gets rid of the stains fast...but...BIG BUT...... at $99 for a 5 gal pail (plus tax and shipping), you will need to factor that into your pricing, however, you will have one very happy customer..:)
 
Ditto what memo said...plus add shipping to the $99. Two things about DR60...1) scrape as much gunk from the surface first 2) DR60 must be applied to a DRY surface, so if it needs to be re-done, you'll have to wait or come back...the BIG downside.
