Epoxy Coating Over An Oil Stained Floor

Epoxy Coating Over An Oil Stained Floor

If your floor is full of oil stains you need to be very careful on how you prep it before applying any epoxy coating to it. Oil stains are at best difficult to get out and in most cases can be downright impossible to remove. If you have light oil stains you can use our Oil & Grease Remover or similar quality product. You can use Liquid Tide scrubbed in with some Muratic Acid. If either or both those methods fail then you need to use our proprietary Oil Stain Primer . It is specially engineered to actually bond with oil on the molecular level. It is the only way you will get epoxy to stick to your floor. Also if you have stains all over the place we recommend that you prime the whole floor so that you don’t get different color shading in the epoxy since the primer is very dark in color.

Epoxy Coating

As you can see above even grinding will sometimes not even remove oil stains. Here the grinder is just spreading the oil all over the place. Lots of times the oil is so deeply embedded into the concrete  no matter what you do,  you will never get it all out. This is when you clean it up as best you can and then prime the floor with our patented epoxy oil primer and then epoxy paint over that.

If you think you were able to clean the floor of all the oil but are not sure cause the concrete may be a little darker where the stain was. Simply sprinkle some water on the spot and see if it beads up or turns a rainbow bluish color. If it doesn’t do either than you’re good to go. If it does either or both you can try cleaning again or go with the primer to be safe.
