The Best Way to Get Rid of Mold from Your Floors

Wood floors can be a homeowner’s pride and joy when it comes to his house. These are beautiful and age wonderfully well. There are instances when blemishes do occur in the form of mold. Despite the practice of sealing the floors with a protective coating, there are times when a mold infestation can break through. Before you call an expert to deal with the problem, it may be within your capabilities to deal with the blemish yourself.

What You Need

There are some materials and tools that are useful for cleaning up mold from wood floors. These include the following:

  • Fine sandpaper (100 and 200)
  • Microfiber rug
  • Vacuum (optional)
  • Polyurethane finish
  • Small paintbrush
  • Bleach (optional)


Before anything else, your safety is the priority. Mold can be potentially dangerous and precautions should be in place in order to successfully repair the blemished flooring. Open any doors and windows in the room or area where you will be cleaning up. Good ventilation is important.


The first thing to do, after opening windows and doors, is to assess the entire floor for any other spots that may have molds. This is so there is only one concerted effort to remove the mold from the floor instead of repetitive efforts when you discover more spots. Once you have established the mold infestations, mark these or clear the area so you will not forget.

Clean Up

If the mold is only on the polyurethane coating, you will just need to wipe it clean from the coating. If the mold has permeated below the coating, you need to pry off the coating or sand off the coating with the mold. It is preferable that you wear a mask since you will be working up close to the mold and sanding can send it airborne.

If you were lucky enough and the mold was just in the coating, just wipe the area to remove the dust. Your rag should be a microfiber one or if it is just an ordinary rag, dampen it so the dust will not fly around. Be careful doing this.

Sometimes, mold will penetrate the polyurethane coating and enter the wood grain. If this is the case, some sanding is necessary on the wood itself. Use the 100 sandpaper first and then follow up with the 200. Your sanding motion should be gentle in order not to make any more damage to the wood.

To prevent any mold from spreading, you might want to spray some bleach on the area. Do this with care since bleach might whiten the wood that you are working on. It might also compromise the integrity of the protective coating. If you are wary of doing this, then do not. This is just an additional precaution.

When you are satisfied with the results of your labor, wipe the entire area and some of its surroundings with the microfiber cloth or a rag that has been dampened with white vinegar o the bleach solution. Let the area dry fully before applying the polyurethane coating.

After several hours, or maybe the next day, brush a thin coating of polyurethane over the sanded area and its surroundings. Make sure the initial coating is thin enough that it does not look watery when dry. Add more coatings as you see fit. Leave it alone to dry for several hours.

Getting rid of molds from a wooden floor should be easy enough but there are times when there may be too much mold and you will need the help of an expert or a professional. Make sure you have assessed the problem properly according to your capabilities and do not take on the task if you have doubts. Remember, your safety is the first priority.
