To dry out small spots, place a fan in front of the damp area and turn it on high. For larger spots, install a heavy-duty dehumidifier in the room to suck the water vapor out. If you need to dry out a wall in an enclosed area, place moisture absorbent materials like dehumidifier packs near the damp spots.
Yes, damp drywall can dry out, but the process and effectiveness depend on several factors: Extent of Moisture: If the drywall is only slightly damp, it may dry out on its own over time. Heavily saturated drywall, however, may take longer and might not dry completely.
The plaster will need a minimum of 3-5 days to achieve full dryness, but for some jobs, it may take up to 4 weeks. Once it's dried, the plaster will appear pale pink, and any previous brown patches will have disappeared. Not allowing the plaster to dry sufficiently can also harm the quality of the finished job overall.
Sometimes, damp plaster may take several weeks or even months to fully dry. However, it's important to note that more than simply waiting for the plaster to dry on its own may be needed to address the underlying cause of the dampness, which could lead to further problems in the future.
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.
Some damp is caused by condensation. Condensation is perhaps the most common form of dampness that can appear in your property. It can cause wallpaper to peel, damp patches to appear on walls and a build up of moisture on your windows. This can lead to a growth in mould that appears as a cloud of little black dots.
Increase airflow
Good airflow will help to encourage your plaster to dry more quickly. If it's not too cold, it can help to keep windows and doors open. Similarly, a fan can help as long as you keep it on a low setting so that it doesn't cool down the room too much.
Another factor that will affect the drying time for your plastering work is the room temperature and ventilation. It can be tempting to turn the heating right up to speed up the drying process but this is not recommended. Excessive heat will cause the plaster to dry too quickly which may result in cracking or hazing.
Common signs of penetrating damp include things such as:
Damp patches (often looks like a brown stain) suddenly appearing on an interior wall, ceiling or near a chimney breast. Wet and crumbling plaster. Large bubbles appearing under plaster (can often lead to holes in the ceiling if left untreated).
The short answer is no - painting over damp is a short term fix at best. At worst, it can end up making the problem a bigger and ultimately a nightmare.

No mold doesn't always grow after a leak. If the temperature isn't right or if the leak is properly dealt with quickly, there's a chance that mold spores won't be able to take root or grow.
To recap, this is how to repair water damaged drywall:
Cut them with a utility knife. Further dry the water damaged walls using fans and dehumidifiers. Sanitize and deodorize the area to eliminate musty smells and bacteria. Replace the cut-out portions of the drywall.
Place one or more fans in front of the damp spot and turn them to their highest setting. This helps dry the wall and also gets moisture out of the air. If the fan has an oscillation feature, you can use this to clear more than one damp spot that is within its reach.
Plaster generally takes around three to five days to dry fully. It will turn from a brown colour to pale pink. Then, you can apply your mist coat of paint or wallpaper. How long the plaster takes to fully dry can depend on how thick it is, and the conditions of your home.
Damp plaster is, unfortunately, often beyond saving. This means that in the event your property has succumbed to a form of damp that has affected your plaster that more often than not, your plaster will need to be removed (otherwise known as 'hacked off') and reapplied.
If you need to dry your plaster faster, there are a few things you can do. For instance, you could use a hairdryer on a low setting, but this should only be done in small areas.
Heating helps to dry out any existing dampness in walls, floors, and ceilings, and can also help to reduce the risk of mould and mildew.
How to speed up the drying process. The drying out of the new plaster is enhanced significantly by increasing ventilation to the area. Opening windows and doors, and the introduction of a dehumidifier, will remove moisture in the atmosphere. The introduction of heat must be considered with caution.
Random round wet patches are often the result of condensation. Condensation forms because warm, moist air meets cold walls and ceilings.
Rain penetration leaves signs like other damp that are spotted by property owners, which warn them of the damp issues. The main sign is the damp patches on the walls or ceilings that increase in size and become darker after it has rained heavily. It is due to the amount of water that has penetrated the house.
