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.
Question: Sanding To Remove Mold
Denis said:I had a roof leak that allowed water into the attic affecting the an area of insulation, roof rafters along with a 12×18 bedroom ceiling.
My question is, does sanding the affected roof rafters and removing all of the attic insulation the correct process? Why sand? Why not wipe down the affected wood structures.Thanks,

There is no requirement for sanding to remove mold you can scrub or wipe off moldy surfaces with cleaning products but you will probably want to treat the dried surfaces with a fungicidal sealant as well. In fact the cost of sanding for mold remediation is rather questionable except where it is needed for cosmetic reasons such as perhaps leaving an exposed beam in a living space.

How Long Does It Take To Replace A Subfloor
Replacing a subfloor is an easy and fast job for a professional. It can take him about three hours to do it. However, replacing the entire subfloor takes longer, and it can take a professional up to 24 hours, depending on the size of your floor. This is because the professional has to remove the entire floor before replacing it.
Five: Dry The Cleaned Subfloor
Drying the cleaned and sanitized subfloor is absolutely critical and needs to be done before you even consider installing the new hardwood flooring. This might call for turning up the heat, placing a drying fan, or leaving a high-capacity dehumidifier running in the room for two to three days.
Once the floor is dry, you should consider applying a mold inhibitor to the subfloor. This ensures that any lingering traces of mold that might have escaped your cleaning attempts, wonât be able to spawn a new active colony.

If you are not familiar with wood sanding or refinishing, ask questions at a home improvement store about the right sandpaper grit to use for your situation.

Preventing Mold On Hardwood Floors
The two best ways to prevent mold are to clean regularly and to keep moisture from getting to the wood in your house.
Wood floors should be mopped with a light cleaning solution designed for hardwood. This can help to remove the first mold cells before they grow and eat into the hardwood floor.
Make sure to wring the mop out so you do not put too much water on the wood. Its a good idea to dry the floor with a microfiber mop afterward.
Mopping every few weeks will go a long way to prevent mold growth.
There are several things you can do to keep moisture low on your hardwood floors:
- Always dry up spills or excess mop water right away
- Inspect plumbing occasionally and fix any leaks
- Also inspect windows and doors and repair leaky seals
- Control splashing in common areas with rugs, a shower curtain, etc.
- Seal crawl spaces and sump pump basins that can humidify your house
Any large amount of water can cause mold. Even small amounts of moisture can let mold grow if the area is frequently wet. You can buy a wood moisture sensor if you are concerned about humidity affecting the wood in your house. This machine will give you a percentage of moisture content for the wood to show whether you are in danger of growing mold.

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.

Guide To Cleaning Mold From Smooth Wood Surfaces
Perfectly adequate moldy-wood-surface cleaning may be accomplished by wiping or power-washing or media blasting.
Where wiping a moldy surface, take care not to spread moldy debris from a moldy surface onto a previously uncontaminated surface by making the mistake of re-using the same moldy rag over and over on all surfaces. Professionals use “steri-wiping” which takes care to avoid spreading moldy debris by always folding and using a clean side of the wipe when moving to a new spot.
Where the framing lumber is indoors or otherwise in a location where water spillage is a concern, wipe theareas of heaviest mold to remove any loose mold from the surface of the lumber.
Unless professional area-containment has been set up , do not use violent cleaning methods such as power-washing or sandblasting indoors, as you will spread moldy debris throughout the building and you’ll increase the ultimate project cleanup cost.
Wherethe framing lumber is outdoors where water spillage and the creation of aerosolized mold spores is not an issue, pressurewash the infected lumber to remove surface mold.
“Cleaning” in this case can be simply wiping with a sponge wet with water or detergent.
The object of cleaning is to remove most of the loose moldy particles.
A professional uses sterile wipes and folds to a clean side of the wipefor each wiping stroke. For a small homeowner non-critical project this may be overkill but think about and avoidspreading moldy debris by your cleaning procedure.
