Oily contaminated concrete is very difficult to bond to, but it can be done with special care and Epoxy.com Product #201 Oil Stop Primer. Plant floors, warehouse floors, commercial, and residential garage floors can all have this problem. Here is a typical question that I get about oil contaminated floors:
“We were looking at your product because we have a floor in a maintenance garage that is pretty well soaked with oil. A new tenant is going into that space so we know that there needs to be something to allow the new floor to stick and to stop the odors.”
Here is my typical response:
Is the oil saturation petroleum oil? If so you need to:
- Degrease the floor
- Mechanically clean the floor – www.epoxy.com/surfaceprep.aspx.
- Apply 1 coat of Epoxy.com Product #201 – www.epoxy.com/201.aspx – at a rate of 200-320 SF per gallon.
- Inspect for bond the next day. If bond fails remove the loose #201 and go back to step one.
- If bond is good check for oil on top of the primer. If there is oil on top of the #201 and it is well bonded remove the oil with xylene or other effective degreaser.
- Coat with 2 coats of Epoxy.com Product #2 – www.epoxy.com/2.aspx.
I like the Product #2 for these applications because it is very resistant to petroleum oils. Depending on your specific application the material you use over the #201 can be a number of different flooring, coating systems or chemical resistant epoxy floor systems.
