Remove Oil And Paint Residue Before Sealing Your Concrete Garage Floor

Your concrete garage floor takes a beating from all kinds of elements.  Over time, the surface of your floor can become caked with oil, grease and paint splatters.  If you want to reseal your garage floor, you need to thoroughly clean the floor and remove any residue.  Here is how to remove oil and paint residue from your concrete garage floor quickly and easily.

How to remove oil residue

New sealant will not properly adhere to the concrete if you have oil residue on the surface.  Sometimes it's hard to tell whether it's an oil residue or something else.  If you sprinkle water on the area, and it just sits on top of the concrete without soaking in, then there is oil residue there. 

  • Wet the floor first to make sure that the oil doesn't travel to adjacent concrete and create new stains.  Then, mix laundry detergent with warm water and scrub away with a stiff nylon brush.  Don't use a metal brush as it will damage the floor surface.
  • If the residue is overly thick, apply laundry detergent straight out of the bottle to the affected area, let it sit for a few minutes, and then, repeat the scrubbing process. Rinse with water and let the area dry. 
  • Now, test the surface with water to see whether it beads up or soaks in.  If there is still some oil residue, use a heavy duty concrete degreaser and apply it full strength to the stain.  After a few minutes pass, rinse it with a pressure washer or a garden hose with a sprayer.  Don't worry about discoloration of concrete as it won't interfere with the application of new sealant.

How to remove paint residue

Before resealing the concrete, you need to strip the floor of any old paint residue.  Otherwise, the new paint may peel or crack after a short period of time. 

  • First, wash the surface with some soap and water.  Because you will be using a chemical cleaner, it's important to wear gloves and a respirator or dust mask to protect yourself from injury.
  • Apply a layer of chemical paint stripper and leave it on for the length of time specified on the product packaging.  To deal with the fumes from the stripper, leave the garage door open and avoid the area until it's time to clean.  After sufficient time has passed, wash the area with a pressure washer. 
  • If you want to avoid the use of chemicals, you can rent a floor grinder or buffer from your local hardware store.  It will take a little more elbow grease, and generate more dust, but it's an environmentally friendly and effective method.

It's important to prepare a clean and residue free surface before sealing a concrete garage floor.  Follow the steps above to remove oil and paint residue and enjoy a fresh, primed surface ready for the new sealant, bought from a location like LSC Construction Services, Inc.
