With a drywall scale meter, accurately measuring moisture is as easy as pushing the pins of the meter into the drywall and taking a reading. The meter will provide an exact measurement that you can use to determine the moisture content of the drywall.
One of the most obvious signs of water-related problems in any structure is the appearance of dark patches in walls, ceilings, and other surfaces. As water seeps into building materials, it tends to cause the materials to visibly darken.
Generally speaking, for drywall, a safe moisture content (%MC) would be less than 1% MC. Anything above 1% MC in drywall would indicate a level of moisture that could compromise the integrity of the gypsum board.
Even a reading of up to 17% means that the drywall is salvageable, but any moisture level above 17% tells us that the drywall has been compromised and will need to be replaced, or cannot be used.
Mold inside walls often stays within the walls. But when it does migrate to the drywall paper, wallpaper, paint, or baseboards, it appears in patchy clusters of small spots. Mold can be black, white, gray-green, or gray-brown.
When it comes to water damage on your walls, look for the following signs: Softened drywall, discoloration (often appearing in the form of streaks that can be short or quite long, running down the wall in affected areas), water rings (usually a light brown color), cracked, bubbling, or flaking paint, musty smells.
A guide on how to dry damp walls:
– Find and fix any water leaks near your walls.
– Drain away any water standing in the walls.
– Remove damaged areas of a wall so there are no long-term issues.
– Grab a room fan to dry small damp spots.
– Buy a dehumidifier for large damp patches.
– Use desiccants to absorb moisture.
Three signs of too much moisture in a home include: condensation on windows during the winter, excessive mildew in the bathroom, mold growing on interior surfaces (corner of a closet, kitchen or bathroom), peeling, cracking, or blistering paint on exterior or interior finishes, dust allergies (caused by dust mites).
A big question homeowners often ask is “does wet drywall always need to be replaced” and the answer is almost always yes. Water stains, discoloration, bubbling, peeling paint, and softened areas are all signs of water damage and are not nice to look at.
Use fans to move air around the damp walls. Also use dehumidifiers, which can help remove moisture from the air and walls. Professionals use tools like moisture meters, infrared imaging devices, dehumidifiers, and heavy-duty fans. That ensures the walls are truly dry before further repair, painting, or refinishing.
Mildew and mold will develop within 24-48 hours of water exposure. Even worse, it will continue to spread until steps are taken to eliminate the source of moisture, and effectively deal with the problem.
