Epoxy paint is a popular garage floor coatings because it is incredibly resilient under intense pressure. Unfortunately, this same quality makes it almost impossible to eliminate friction by using alone. If you want to remove an epoxy layer from your garage floor, you will have to apply one or more acidic washes to the surface. However, before starting, it is necessary to know the appropriate application and safety measures to use.
Open the garage door to provide ventilation. Use acid-resistant glasses, overalls, gloves, boots and a respirator with acid-grade filters. Moisten the garage floor only lightly with a water hose. Dry the water pooling the use of towels. Add one gallon of water to the 5 gallon bucket. Gradually mix in 12 ounces of acid using a long-handled brush. Do not add acid to the 5-gallon bucket before adding water as this can lead to acid splashes from the container.
Apply the acid solution to the epoxy coating using the long-handled brush. Do not pour the acid directly on the surface. Let the acid stand for ten minutes. Neutralize the acid by generously spraying sodium bicarbonate on the surface. Let the soda sit for five minutes and then rinse the surface with a water hose. Remove any remaining epoxy, focusing high water pressure on it using the pressure washer. Repeat steps four, five, six and seven until all of the epoxide has been removed. Add one gallon of water to the 5 gallon bucket of acid. Add the baking soda until the contents stop effervescence. Arrange of the neutralized acid excess in a toilet or storm drain.
