What happens when water gets into plaster?
Saturation. While water can cause damage by softening the plaster itself, the problem may be even worse inside the walls. If the wall is saturated with water, the wooden lath behind the plaster will absorb water and begin to expand. As it expands, it pushes outward and can cause the wall to crack and weaken.
What does water damaged plaster look like?
Paint and water are insoluble and an easy way to identify if plaster is water damaged is looking for flaking paint or air bubbles that burst and flake. Unlike flaking plaster, paint will flake with minimal exposure to water, while plaster often needs to get wet and re-dry before flaking occurs.

Can you paint over water damaged plaster?
If the damaged bit of plaster is only a water stain and there’s no underlying leak that will recur, use a stain-blocking primer such as a Kilz sealant. Once that’s dried, you can proceed to paint the area. You also need to choose the right kind of paint for the project.
Do ice dams always cause leaks?
Last but Not Least…Ice Dams
While not always the case, ice dam causing leaks are usually plainly visible from the ground (See Ice Dam Company Case Study #20). The steeper your roof pitch, the more ice it takes to create interior leaking (See Ice Dam Case Study #09).
Is ice damming the roofers fault?
True: Ice dams are not caused by faulty installation or bad roofing components. Ice dams are caused when cold air around the soffit meets warm air inside the shingles right above the soffit.
Do ice dams always cause damage?
Ice dams can cause damage even when they are very small and thin. The slope of your roof matters here: a steep roof will generally be ok with a thin ice dam, while a lower-pitched roof can incur significant damage from even a 1-inch thin ice dam.
How long can moisture stay in walls?

When should I be concerned about plaster cracks?
New Cracks Can Signal Foundation Problems
If your home is older and you see new cracks in the plaster, it might be a sign of a foundation issue rather than a cosmetic one. Check the basement or crawl space below for cracks. If you see them there, you might have a foundation issue that needs addressing.
How do you determine if the cracks in walls are serious?
Large, jagged, or diagonal cracks could indicate a structural problem. Jagged or diagonal cracks indicate that the foundation may have shifted or sunk, or another problem has occurred, such as the deterioration and collapse of supporting wood members due to termite damage.
How can you tell if a crack is structural?
As the name suggests, structural cracks occur because of poor construction sites, overloading or poor soil bearing.
Telltale signs of structural cracks in your foundation are:
- Stair-step cracks.
- Cracks on foundation slabs or beams.
- Vertical cracks that are wide at the bottom or top.
- Cracks measuring 1/8″ in width.
What’s worse vertical or horizontal cracks?
Horizontal cracks
They usually occur because of excessive outside pressure, such as shifting soil, water pressure, or other sheer forces to the foundation. Horizontal cracks are much more dangerous than vertical cracks because they can quickly lead to total foundation failure.
What do settlement cracks look like?
Settlement cracks in walls can be vertical, horizontal or diagonal and in floors they aren’t necessarily straight. They can vary in width but, if crack widths are less than 2mm wide, they are unlikely to affect the structural stability of your home.
What causes cracks in plaster walls?
A: Old lath and plaster walls are prone to cracking. Over time the plaster separates from the lath, creating structural cracks. Plaster is also prone to thinner spider-web cracks, which occur when the topcoat of the plaster degrades. It’s common to have both kinds of cracking — and both types can be repaired.
