How to Make Painted Concrete Floors Shine

A concrete floor can add simple sophistication to any indoor space, often providing rich color with an inviting sheen. After applying paint to a concrete surface, you may wish to make painted concrete floors shine with a glossy finish. Achieve the luster you desire in your concrete floor surface by applying a topcoat over the paint. Not only will the topcoat make the concrete exude a gleaming polish, but the top layer will also protect the paint layer from wear and tear.

Vacuum cleaner (with brush attachment)
Urethane sealer
Paint tray
Angled brush (3 inches wide)
Paint roller (with extension handle)

Instructions

- 1
  Vacuum the concrete surface with the vacuum cleaner and the brush attachment. Use the attachment to remove dust and dirt from all corners.
- 2
  Pour the urethane sealer into the paint tray. You will require approximately 1 gallon of urethane for every 275 to 300 square feet of concrete flooring.
- 3
  Cut in the outer perimeter of the concrete floor, applying the urethane to the perimeter of the floor with the angled brush.
- 4
  Attach the extension handle to the paint roller to enable easier application. Dip the roller into the urethane in the paint tray to coat the roller evenly.
- 5
  Brush the roller onto the concrete floor in the corner farthest from the exit door. Apply the urethane in a thin and even layer over the floor. Apply the urethane to the entire floor surface as quickly as possible before it begins to dry.
- 6
  Allow the urethane to dry completely for the time recommended on the product label.
- 7
  Apply a second coat of urethane to the concrete floor, using the same method you used to apply the first coat.
