How to Repair Stained Concrete Flooring

Stained concrete flooring is not an attractive look. Concrete flooring is used by a lot of homeowners, because of its durability and low maintenance. However, concrete flooring can collect stains from oil, to dirt and grease. These can ruin the look of concrete, and lessen its value. No matter what surrounds the concrete, if it’s stained very badly, everything else around it loses value too.

Concrete flooring stains are not that hard to remove, if you have all of the right tools and resources. Most concrete stains can be removed with just a few household items that you may already have on hand. How you repair the stain will depend on the type of stain. It is not advisable to use any type of ammonia or vinegar on concrete flooring. These cleansers are extremely harsh on the flooring, and may cause the finish to run. Use caution, such as safety goggles or gloves when handling toxic chemicals. The items and steps to repair stained concrete flooring are listed below.

Tools Needed for the Job

  • Power Washer
  • An Old Mop
  • Citric Acid Cleanser Mix
  • Old Towels
  • Clear-Coat Concrete Protectant
  • Broom
  • Dust Pan

Step 1 – Washing the Stained Area

Use a power washer and some soap, to wash the stained area thoroughly. Try to get the stained surface as clean as you possibly can, in order to uncover the stain completely.

Step 2 – Removing Debris

Remove any debris or objects that may be blocking any access to the stained surface. You may do this by sweeping them away with a broom.

Step 3 – Applying the Cleanser

Mop over the stained area with the citric acid cleanser. The stained surface will need to be completely covered with the citric acid cleanser. All the mixture has to be soaked into the stain for about 1/2 an hour, or up to an hour at most. This will allow the cleanser to soak into the concrete floor stain completely. This citrus based cleaner is also recommended to repair paint stains on the concrete flooring.

Step 4 – Mopping the Cleanser

Use old or disposable towels to mop the cleanser up. The acid in the cleanser should be able to lift up the stains from the concrete flooring. Use this method to mop the concrete floor surface, until it is just about to be completely dry. If the stain does not appear to be coming up quickly, the acid may need more time to soak into it. 

Step 5 – Applying the Concrete Flooring Protectant

When the flooring surface has completely dried, apply some clear coat concrete flooring protectant to the entire floor. This protectant will block any other stains from occurring. It will also give your concrete flooring a new look and last for years.
