Do you want to know how to fix peeling paint on ceiling? The paint on your ceiling cracked first and is peeling off now? Or is it peeling and falling apart? Find out where this common problem comes from, and which renovation work you should consider to solve it.
How to Fix Peeling Paint on Ceiling
Like all matt paints, ceiling paints are the most prone to flaking. Application conditions, humidity, or mechanical stress may be among the causes.
The classic causes, observed on all types of surfaces, are as follows:
Poorly adapted, poor quality paint applied to a chalky surface, incompatible superimposed products, and a dirty, greasy, or poorly dusted surface to be painted. These causes can lead to poor paint adhesion, which results in the formation of flakes.
When renovating, to ensure that the new paint will hold, you must carefully prepare your surface: clean, repair, coat if necessary, sand, and dust perfectly. Eventually, you will have to stabilize it by applying a fixative if it flours.
You will have to choose quality coatings, undercoat and paint products, that are compatible. Also make sure you eliminate all sources of moisture on the surface. Finally, work in the humidity and temperature conditions that the paint manufacturer recommends.
To paint a ceiling, or even a wall, coated with an old glycerol paint, with an acrylic paint, a specific primer is essential. Indeed, a layer of water-based paint will adhere very badly on old oil-based paints, which are too smooth.
Causes of Flaking Specific to Ceilings
Water infiltration from a dwelling on the upper floor or from the roof of a house often degrades ceilings. Before any renovation, the source of the moisture must be found, treated, and allowed to dry out thoroughly.
Mechanical stress is another common problem. Indeed, a ceiling is either on the underside of a floor, or suspended from a frame. When structures are working, cracking and peeling of the paint can occur over time.
Renovating a Chipped Ceiling – How to Do It
If the paint on a ceiling is flaking, the parts that no longer adhere should be scraped off. Ideally, you should use a hand sander equipped with a sandpaper sanding disc and a dust extraction system. Make sure you have protective goggles, a mask, work gloves, and protect your furniture.
Then ensure that the surface is flourless. Rub your hand on it: if it leaves dust, vacuum it well and repeat your test. If your hand is still dusty, then a background regulator will be necessary to restore consistency to the whole. Otherwise, as it dries, the undercoat will peel off.
If the flaking was extensive and you have peeled off a lot of paint, you may have lost the flatness of the surface. In this case, apply a smoothing compound. Once it is completely dry, sand it. You can then apply a suitable primer and then the finishing coats of paint.
