Floors in battery charging areas see a considerable amount of heavy mechanical wear, impact and chemical attack from the sulfuric acid (about 20-30% concentration). Hence, a thin film coating cannot be expected to provide more than a stopgap solution.
For far superior long term performance, we have had excellent success with our resin-rich, ICO Floor 51 troweled system applied at a minimum thickness of one quarter inch. It resists up to 50% sulfuric acid for seven days and is a flexibilized system that will better resist impact than conventional, more brittle epoxies. And because it is a resin-rich material it does not rely on a thin “sealer” coat for protecting against liquid infiltration, thus enabling this floor to far outperform conventional dry, top coated floors.
There are a few other concerns, however, that should be addressed. One is the staining issue. Sulfuric acid will stain resinous floors, usually turning a gray floor pink. While this does not mean there is chemical attack, if this unsightliness is objectionable to the customer, then we suggest adding a top coat of our Ure Guard 100 which does have better stain resistance. Note, however, that especially with an added urethane top coat it is important to regularly wash down the floor if there is battery acid spillage, as if left exposed for too long, water evaporates, resulting in the 20-30% acid turning into a more concentrated, aggressive version, thereby resulting in a potential chemical attack on the urethane, but not the epoxy floor underneath it.
