Diatomaceous Earth and Portland Cement

[One Tough Pressure]

Awhile back I read an article online regarding using diatomaceous earth and portland cement mixed together to eliminate oil stains on concrete. I have not yet tried it, but can envision that it work well.
I would not be surprised if that is what is in these dry clean up products that have come on the market in recent years.

Anyone have any experience with the Portland and DE?

Interesting........Let us know if you give it a whirl and have good results.

These products are used as part of a poultise to draw out the stain.

I Have Talked To A Friend That Used Straight Portland To Do The Same He Said It Worked Well You Will Have To Let It Sit For About 24hrs Or So. If It Is Humid In Your Area Dont Do It Because Well You Know What Happens With Cement And Water.

I have some of the D.E. but do not want to try it with the Cement. As soon as I get a job or a place that it will be able to sit for a few days I will do some experiments. I cannot find the D.E. at a cheap price. A 25 pound bag was 35 dollars. Hope I can find it cheaper. I was told to make a poultice with different chems and change it out every few days and it might work depending on how old the stain is.
