Downsteam 12% or Oxalic acid?

[reflectionspw]

Which one do you guys prefer to use on freshly cleaned concrete? I've been using 12%, but read somewhere how some like using oxalic instead. How much oxalic do you mix in a 5er? Thanks!

 

[Doug Rucker]

I personally never use oxalic.

 

[Russ Spence]

neither? Whats the point if its cleaned?

I dont like to use oxalic anyway unless I am neutralizing with it

i use it on some concrete when overlap streaks tend to show up more.

Slow down with the surface cleaner!!!!

We use 12% when needed too.

I am not knocking anyone for doing it but I just dont like the whole idea of spraying any chem and leaving it somewhere?

 

[Paul Kassander]

I will use it for rust stains and thats about it. Whenever I use it I always neutralize and rinse when done though. I don't like leaving any chems behind especially those that are not neutralized.

:yeah: Same here. We do however on most all Concrete Cleanings DS a coat of Housewash mix onto the Concrete just to be sure that we have killed all the mold spores. It also brightens it up a bit once dried.

Thanks, but we really aren't going too fast. I've just noticed in on some of the rougher textured concrete were the overlapping occurs. I haven't had any complaints about it, but I'm one of those OCD type people and they drive me nuts.

I figured you weren't....I was just kidding. Nothing worse than stripes on concrete.
