How to Clean OSB Mold?
The oriented strand board (OSB) is one of the most commonly used items for building roofs, walls and floors. It is also the material used to support the weight of your house. OSB is very good material, but if you get it wet you will have to deal with mold growth which could get expensive. Here are a few tips to avoid the problem and clean infested areas.
Repair all leaks and fix high humidity. Dry wet areas as these are breeding places of molds. You can also use an electronic air cleaner and spray fungicide. If you are moving to a new house, do not take contaminated items with you.
When you find mold in your house, locate other areas where it might also be growing. If your house smells moldy, and if you know that there have been some water leaks, your house may be infested. Usual problem areas are:
- Top of ceiling tiles
- Under carpets
- Back side of wall
- Heating/cooling ducts
Scrape particles into a do-it-yourself mold test kit which you can buy at hardware stores. Do the test at least five feet from the porch or roof so that you can compare the results with an indoor test.
Painting over problem areas is not advisable as this would only cause more molds to grow. Use 6-millimeter thick plastic sheeting to contain infested areas. This should cover all walls and ceilings. Dry your work area afterwards with an industrial-sized dehumidifier. Remember to wear protective gear such as a biohazard suit, goggles and gloves.
Replace infested equipment, especially heating and cooling ducts, if you have the money. If not, schedule mold fogging or spraying regularly for 30 minutes to one hour per session. Fogging is generally more effective than spraying. You can also use chlorine and oxygen bleach for cleaning.
As you can see, cleaning OSB can take up your time. If you were sold a house with OSB mold without your knowledge contact an attorney. Also, avoid this problem by having the home inspected before buying it.
You may choose any of the types of bleach to remove molds, but nothing beats good workmanship for a life-long protection.
