Has water damaged your plaster ceiling? Not sure of what to do? We can help, keep scrolling to find out. 

In older, historic buildings, the inevitable and often visible cracks will appear in your plaster ceiling. And not only in older buildings but any house that has a plaster ceiling. Further, cracks or damages can occur due to many factors and can prove costly and difficult to rectify.

As a homeowner, you would always cringe when you see cracks appearing in your ceiling. That said, if the cracks are already there, your best chance to salvage your ceiling and to avoid the continuous brown, scratch, and white coats falling from your roof is to repair the plaster with a setting-type joint compound. And keep away from the ordinary ready-mixed mixture; they aren’t suitable for this type of job, at best they will hold out for a short while, but once the compound begins to dry, the cracks will appear again. 

Nevertheless, once you have the right compound, you can replace and restore your ceiling to its original state, providing you have the level of skills and experience in plaster ceiling repairs. Otherwise, leave it alone and contact a professional plaster ceiling repair company to take care of it for you.

What Causes Plaster Ceilings to Damage?

If you have a plaster ceiling in your house, know that you have a very durable and strong material that can outlive you, and even last for centuries to come. You won’t need to do costly repairs and replacements with a plaster ceiling in your house. However, there are odd occasions when accidents and unforeseen things happen. Things like:

  • Dried out base layer
  • Compound that is not suited for longevity
  • Leaking roof
  • Humid climate
  • Flood from the floor above
  • Renovations elsewhere in the building
  • Lath movement
  • Overloading
  • Settlement/vibrations

Otherwise, you can repair and replace your plaster ceiling by yourself using a combination of standard materials with classical technique. 

The first thing you want to do before you attempt to repair your walls or ceilings is to identify the cause of the damages. This might be difficult to do in most cases, that’s why we recommend contacting a professional company. However, if it’s a case of water damage, you must locate the source of the leak and stop it; unless you want to do more repairs soon.

Now, remove the damaged portion of the plaster ceiling using a putty knife. After all the peeling paint, degrading lath, bubbling and crumbling plaster coats has been removed, be sure to sand down all surfaces to remove any remaining material from the edges.

Seal the Water Damage

Using a stiff nylon brush, go over the damaged area to remove any remaining particles. Then get a sponge, dip it in clean water and wipe off the surface to get rid of any residual lime deposits. Using a quick-dry primer or oil-based sealer, coat the area. Now, wait until the area is thoroughly dried; usually, the quick-dry primer will dry within an hour, but the oil paint will take as long as 24 hours to dry.

Repair the Plaster

Using mud, fill in the missing plaster and level out the wall. To do this, you will need to apply several thin coats of joint compound to the shallow surface damage. Also, be mindful not to allow the mud to go higher than the other surrounding surface areas. 

Once you have applied the compound on the area, allow it to harden. Then use the joint knife to level it out until all ridges are gone from the surface. And then finally, you complete this phase by using sandpaper to smooth out the surface, a brush to remove particles that the sandpaper may have left behind, a damp sponge to clean the surface thoroughly, and finally, coat again with mud.

Apply a Second Coat of Mud

Just as before, apply a second coat of joint compound—only this time in a smaller amount. The primary focus of this second coating is to fill those deep areas that you may have missed from the first round of coating. 

Sand and Touch Up Paint

Once the previous coat is completely dried, you must now sand, brush and wipe off the surface, but make sure you sand with 120 sandpaper. Using a primer-sealer, prime the new area and surrounding areas. At this point, you are finished, but allow the primer to dry before you apply your favorite paint to the wall.
