Apply an Epoxy Coating to the Floor
To protect floor, apply a tough epoxy coating that resists oil, dirt and hot tire pickup.
Make sure concrete is sound without cracks or divots,
Use heavy duty degreaser to remove dirt and oil stains.
Working in 4x4-foot sections, apply concrete etch. Use a stiff bristle brush and plastic watering can to apply etch.
Rinse each 4x4-foot section after it has been etched, then rinse entire floor twice.
Cut in epoxy around edges with good quality, synthetic brush, then roll epoxy onto floor beginning in the back corner. Work in 4- by 4-foot sections, spreading decorative chips over wet surface.
Don't walk on floor for 12 to 16 hours. Keep heavy items off for 24 to 48 hours; wait three days before driving vehicle onto floor.
