Does water damaged plaster need replacing?

Older lath and plaster ceilings stand up to water damage reasonably well and even a crack up to 1/4 inch can be repaired. If your plaster or drywall ceiling is crumbling, swollen or bulging even after drying or shows signs of mold growth, the material should be replaced by a professional.

Can plaster be left unpainted?

Left unpainted, like clay plaster, it takes in moisture and releases it—and unlike clay plaster can be used in kitchens and baths (but shouldn't be exposed directly to water). (These days a moisture-absorbing board known as blue board has replaced lath.)

How do you dry out a damp room?

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.

Why does wet plaster crack?

Drying shrinkage cracks are the result of moisture loss after the plaster has hardened. Plaster applied in layers that are too thick will also tend to crack in this way. These cracks are normally stable and can be filled with a proprietary filler and painted over.

Is musty smell dangerous?

A musty smell is dangerous because it indicates the presence of mold or mildew. We mostly associate mold with old houses, but it can become a problem even in your new apartment or house. Mold only needs a surface to thrive on, mold spores, moisture, warmth, and oxygen.

Does musty smell always mean mold?

As we have seen, the most common reason for a musty smell in your home is the presence of mold or mildew. And because the microbial volatile organic compounds (MVOCs) emitted from mold and mildew have a low odor threshold, a musty smell does not necessarily mean that there is a lot of it.
