Hello I work for a manufacturer of a resilant vinyl flooring system. Our product is adheared with a two part epoxy over a sound substrate. We have a customer that is looking to use our floor in a warehouse that was used as a paintball facility. The paint is off the floor but everytime they clean the floor within 4 days oil from the cleaning solution they used comes back up through it and leaves little puddles of oil the size of rain drops. I know this would pose as a problem for our epoxy. I need to know what there is out there to actually draw the oil out of the concrete and how long it may take. Please e-mail me at firstname.lastname@example.org or call at 800.544.9538 ask for Mike Michaud or fax information to 800.548.7678. Thank you for your prompt return.
