How to Finish Basement Floors


Part of a basement remodeling project is finishing the basement floor. No matter where you live there is always the possibility that a basement will flood, so when deciding on how to finish your basement floor you should take into consideration the damage that can be done to carpeting and tile by exposure to water. If your basement gets damp consistently when it is raining or snowing outside, then you may want to have a professional contractor seal it from the outside before finishing your basement floor. Given the potential for water damage in a basement, painting a basement floor is the best finishing option.

Things You'll Need

  • Stiff broom
  • Dustpan
  • Basement Floor Sealant
  • Squeegee
  • Weatherproof Paint Primer
  • Basement Floor Paint
  • Paint Roller with Telescoping Arm
  • Paint Brush
  • Throw Rug
  • Remove all items from the basement that sit on the floor and sweep the basement floor thoroughly. Pick up the remains in a dustpan for removal. You will be applying sealant and paint to the floor, so getting all of the dust and debris up off the floor before you start is extremely important. Any dirt or debris left on the floor could prevent your sealant and paint from drying properly.

  • Apply a generous amount of basement floor sealant using a squeegee. The directions for applying the sealant can be found on the container. If it is a dry day outside open the windows to the basement. This will help to air out any fumes from the sealant, and it will also help the sealant to dry faster. Wait until the sealant is completely dry before moving on to the next step.

  • Apply a coat of white exterior primer to the floor using the squeegee. The exterior primer will help to give a solid base to whatever paint color you decide to paint your basement. Allow the primer to dry before moving on to the next step.

  • Apply a base coat of basement floor paint to the concrete floor using a paint roller on a telescoping arm and allow it to dry. If you are doing a complete remodeling of your basement then be sure the color of the floor matches the rest of your remodeling project.

  • Use a paint brush and different colors of basement floor paint to paint any designs you may want on your floor. Only use basement floor paint. Allow the paint to dry before putting anything on the floor.

  • Measure for a throw rug and then place the throw rug on the floor. A concrete basement floor can get cold, and a throw rug will allow you to walk on the basement floor in comfort. If the throw rug does not already have a non-slip backing to it, then be sure to put a rug-gripping pad under the throw rug to hold the rug in place.

Tips & Warnings

  • Keep the windows open in the basement while painting to allow the fumes to escape.
