Prep your cement slab right
A shot blaster is a self-contained portable piece of equipment that shoots metal BBs onto the floor, roughening it and removing about 1/16 inch of concrete. The shot is collected in a rebound chamber and recirculated, while the concrete dust is sucked up by a vacuum connection.
Most garage floors require a full day for prep and patching. The epoxy coating can be applied with brushes or rollers. A durable floor will require at least two coats of epoxy, which must cure overnight between coats. Once the final coat is down, it’s best to wait at least three days before allowing a vehicle into the garage; full curing can take up to two weeks.
