Whilst, you can simply paint over it with a coat of fresh paint, that isn't a guarantee the cracking won't return. Even if the cracking doesn't return, painting directly over cracked paint can leave unsightly texture, which may draw more attention to the area.
If it's cracked badly enough that pieces have come off, use a tiny brush to dab on some brush-on primer and just re-paint the area. As long as you make sure there's enough new paint on there to be level with the thickness of the old paint, the edges should blend close enough to be invisible.
Elastomeric paint - This type of paint is designed to be flexible and can stretch to cover minor cracks and fill in small imperfections. The elasticity helps prevent the cracks from reappearing.
Replying to @Ella 🌊💕 Yes! You can paint over crackle paste after it's dry! I think if you want subtle texture, choose light colors. If not, go with dark colors like I did here!
If the peeling is due to poor adhesion or surface preparation issues, it is generally possible to paint over it. However, if the peeling is caused by moisture, mold, or other structural issues, addressing the root cause is essential before applying new paint.
If the wall is in good condition and the paints are chemically the same (both latex, for instance), you have a few options when the new paint is the opposite shade of the old paint. You can use a primer to thoroughly cover the old color, then apply 1 or 2 coats of the new paint.
Consolidation of cracked painting surfaces may include heat application or small injections of a solution beneath lifting paint. They will also retouch missing areas with an extremely sensitive approach, as well as re-adhering any flakes in order to maintain as much historic and artistic integrity as possible.
Follow this 3-step process to fix cracking or flaking paint: Remove all of the cracked and/or flaked paint in the damaged areas, using paint-sanders*, scrapers, or heat guns. Use the appropriate primer to pre-coat and seal the prepped surfaces. Apply fresh coats of quality exterior latex paints to primed surfaces.
The big mistake that most people make when these cracks appear is to just fill them as they are with a general all-purpose filler and then paint over the top. If you do this, the crack will resurface almost instantly.
Small Patches of Cracked Paint
Use a scraper to scrape off the paint in that area. From there, sand down any remaining loose paint, especially along the wall edges. Apply a layer of patching material. Allow this to dry completely, using a heat gun to speed up the process if you're under time constraints.

Before applying a wrap, the surface must be clean, smooth, and free of imperfections. In cases where lacquer is peeling or there are other paint issues, achieving an adequately smooth surface becomes challenging. Wrapping over such damaged areas can lead to air bubbles, unevenness, and ultimately a subpar finish.
You can, but as with any water staining or damage, you need to identify the cause of the condensation issue in the first place. If in doubt, hire a professional painter and decorator to help you find the source of the problem and advise on the best way of dealing with it before you start painting.
Paint cracking on walls, ceilings, and exterior surfaces happens due to a variety of causes, one of the most common being poor preparation of a surface prior to painting. Painting over cracked paint is a bad idea; it is important to remove any flakes from the surface before repainting.
Simply enlarge the cracks slightly using a scraper (fillers don't work well in hairline cracks), dust off and fill with a suitable product such as Polycell Trade Interior filler. Dampen the hole or crack with water - this will help the filler to bond.
Cracking paint is most often due to the paint system having inadequate adhesion and flexibility, both are common problems with lower quality paints. High quality paint systems are engineered for certain conditions and will include the necessary flexibility and adhesion properties to avoid cracking and eventual flaking.
Whilst, you can simply paint over it with a coat of fresh paint, that isn't a guarantee the cracking won't return.
For surfaces with hairline cracks, when the wall is repaired, choose the flexible primer system that can cover up hairline cracks to make the wall smooth.
But besides being a visually unappealing, cracking, flaking paint can sometimes be dangerous or an indicator of something more serious happening inside your walls. If your building was built before 1978, there's a chance that you could be dealing with paint that has lead in it.
Poor application of paint
Over thinning your paint and applying too thin of a layer can cause the paint to split and crack. Conversely, using a heavy hand to apply paint that may be too thick can lead to what is known as 'mud cracks'.
If you have to remove paint, try gently rubbing the surface around the cracking with a non abrasive sponge under a running tap or soften the paint by floating a small amount of water on top leave for ten minutes and scratch off gently with a pallet knife. Leave the canvas to dry thoroughly before use.
