Some of the most severe and difficult stains in concrete can be solved. Acid leaked from an overcharged or faulty battery on a forklift or electric pallet jack can leave unsighlty white and red damage to your concrete. Essentially, the acid will both stain and etch your concrete if it is unsealed, sealed with a silicate hardener, or if the sealer you have is worn or old. This exposed concrete can then deteriorate quicker, as you have softened the surface paste with acid and created a rougher more porous finish. By treating the acid with a neutralizer immediately following the spill, an inexpensive purchase from companies such as Bonded Chemical, www.bondedchemical.com , damage to your slab can be minimized. Once the spill has occurred, the resultant stain can generally be removed from the surface with a combination of polishing and sealing steps. You will note in the photos before and after that the otline of the stain remains, however, polishing has minimized the appearance and removed the white color variation to the point that the client is satisfied with how the finish was repaired. Moral of the story, don't give up hope when you spill battery acid, neutralize it, then turn to a professional to help you restore your floor!
