Reader Question: Is It Ok To Apply A Sealer Or Wood Preservative Over Black Stains On Plywood Roof Sheathing
Last September I had a new garage roof fitted and within 7 months the plywood used inside developed black mould spots. The company that fitted the roof said it was caused by condensation. Having wiped the roof with a mild detergent I was left with black stains on the plywood. I would like to know if it would be ok to put a wood preservative on it despite the stains – don’t want it to come back.
Would appreciate your advise? –
Reply:
Yes you can apply a wood preservative, leaving cosmetic black stains under the preservative.
But if you do not find and fix the cause of condensation I’d still expect future trouble. You may find stains or mold appearing on other wood or mold-friendly surfaces in the same area if indoor moisture levels are high, or if there is building insulation present that may become mold contaminated.

How Long Does It Take Subfloor To Dry Out
Different factors will have an effect on how long it takes your subfloor to dry out, including what type of subflooring and how much moisture theyve absorbed.
Things like having multiple fans and dehumidifiers can speed up the process, but generally, youre looking at anywhere from 24 to 96 hours for your subfloor to dry out completely.
You wont want to rush this process, because the goal is to remove all of the moisture so that it cant cause any further damage.
Ideally, youll only have to dry them out, but theyll need to be fully dried before you can work on repairing or replacing them anyways. So its best practice to create optimal conditions, and give them the time they need.
What Is The Best Subfloor For Wet Areas
Most commonly, plywood is the material of choice among contractors and the like when installing subfloor in a bathroom. Exterior grade plywood, to be specific, as it has typically been treated against water, and has a high resistance to moisture and humidity.
Other materials like OBS can be more cost effective, but as stated before is less water resistant and is more susceptible to water damage.
Compared to plywood, OBS is also more likely to need replacing if damaged by water, so while the savings may be greater initially, it could wind up costing you more in the long run.
In some instances, such as basement bathrooms, you may not have a choice in the matter, as concrete may be your only option.
If thats the case, and the decision has already been made for you, then there isnt much else to consider. But in any instance where youre given the choice of which subflooring to use, exterior grade plywood really is the best option.

Is Wood Mold Dangerous
All mold has the potential to be dangerous. In the case of wood mold, not only can it cause health issues for the occupants of the building but it can also reduce the structural integrity of the wood it is growing on. Wood mold can be particularly dangerous since it is so difficult to see and may go undetected for very long periods of time.
Drying Out Concrete Subfloor
When water soaks in to concrete subfloor, it can take much longer to dry out due to the environment its in. Concrete subfloor is most common in basements, where humidity can slow the drying process. It is crucial you ensure any source of moisture getting in is tended to before attempting to dry concrete floors out.
That being said, the common theme here continues dehumidifiers running constantly and powerful air circulation are a must. Open the windows if you have any to allow humid air to escape and help dry out the room.
If there was serious flooding or there was a major leak such as a pipe bursting, make sure your electrical wiring has been inspected and cleared by a professional electrician before plugging in anything, even the aforementioned dehumidifier and fans.

Kill Mold With Bleach
Bleach has a powerful sanitizing ability and can kill mold in just a few minutes. However, it has some dangers:
Because of these risks, you might want to avoid using bleach on your floor. It depends on the finish you have on your floor and how deep the mold appears to be growing. You can test an inconspicuous spot to see if it hurts your floors finish.
If you decide to use bleach, water it down in a spray bottle. Use only 1 part bleach to 10 parts water .
Spray the bleach to completely cover the mold. It will start killing the mold on contact, so you do not need to let it sit for long.
Leave the bleach on the mold for no more than 5 minutes . Swipe it up with a rag and throw it away.
Note: You may have read that white vinegar can also kill mold. Some people prefer vinegar because it is natural but vinegar is bad for hardwood floors. Vinegar takes 60 minutes to kill mold, which is way too long to leave liquid sitting on hardwood floors. It can damage the finish and seep into the wood, causing bigger problems. Skip the vinegar for your hardwood floor and use a bleach solution that kills mold faster.
Remove From Wood Floors
As with hardwood, you may notice warping or staining from the affected areas. It can also seep through the wood, causing it to be deeper than it first seems.
You can then add an 8:1 ratio of diluted bleach and water. Spray on the area and allow it to sit for several minutes. Bleach will prevent further spreading and kill existing mold.
If it seems to have penetrated the wood, you can use a scraping tool or brush to match the depth of growth.

If the mold is ONLY the cosmetic black mold that we describe
at BLACK COSMETIC MOLD then it really is only cosmetic and could be left in place.
There are two difficulties with this:
- First you may have trouble recognizing the cosmetic mold I describe in that article, though sometimes the growth patterns make it clear. To address this you could spend roughly $50. to send a representative tape sample of the mold to a mold test lab for confirmation.
- Second, while the black mold I describe is indeed harmless on framing lumber and virtually always came in on the lumber from the lumber yard, also one wants toWatch out: in some cases, particularly on lumber that has been wet, or on treated lumber, my own field and lab tests have found Aspergillus sp. and Penicillium sp. growing among the harmless black mold.
So we might want to clean the lumber.

Drying Out Plywood Subfloor
As stated above, first you want to make sure the source of the water leaking in has been dealt with, otherwise the plywood subfloor will never dry. From there, youll want to block off any passageways and isolate the area to decrease how long it takes to remove the moisture.
Make sure any surface water has been wiped away from the plywood subfloor, then get a dehumidifier set up and turn it up to the highest setting.
Placing as many fans as possible in the room to keep air circulating in the area is also important. Moving air will help remove moisture from the wood, and aid in the drying process. If you can, point them at the wet areas of the plywood directly.
As with the humidifier, set them to their highest setting, and leave them running until the floor is completely dry.
