Soaking with vinegar and water: One of the best ways to remove old paint from walls is with vinegar and warm water. Spray the walls with a vinegar solution and wait for 10 to 15 minutes. Then gently scrape away the paint with a metal painters tool or scraper.
So then I point out that stripping is faster, and in the case of paint could even be safer than sanding. It's almost always better to strip than to sand. To begin with, except in cases where the old finish is flaking off, it's a lot more work to sand than to strip using a paint-and-varnish remover.
Use a heat gun. Wear heat-resistant gloves and blow hot air into the paint. The heat will soften the paint, so you can scrape it off with a plastic scraper. Try using steam. A wallpaper steamer can be used to blow hot steam directly onto the wall to loosen old paint. Again, slowly, soften after scraping.
Peeling paint must be removed prior to applying a fresh coat of paint to ensure proper adhesion. For Best Results: Refer to the how-to for guidelines on removing peeling paint. Using a scraper or 100-grit sandpaper, remove any loose, cracked, or peeling paint from the damaged area.
For every decorating problem, Zinsser has the solution. Peel Stop is a clear, flexible bridging sealer for surfaces where peeling, flaking, dusting or chalking is a problem. It tightly bonds to old paint and problem areas forming a sound surface for new paint.
Peeling Paint
It's not an uncommon problem to encounter paint that will begin peeling again shortly after you've thoroughly scraped the loose edges. And in the past this often meant having to strip some or all of the coatings down to bare wood. Well, an alternative to this drastic action is using a binding primer.
Chemical Strippers
These include caustic pastes and semi-paste solvents: Caustics usually contain lye and work by breaking down organic molecules in the paint responsible for its adhesion properties.
White vinegar solution and detergent solutions work especially well for walls with oil-based finishes. But if the wall is texture-painted, then you might require a bit more deep cleaning.
Paint strippers are solvents that soften the old finish for easy removal. They're available as a liquid, gel or paste and are effective at removing paint from wood on large projects, curved shapes and fine details. Using paint stripper on rounded surfaces and tight areas is often easier and more effective than sanding.
Dimethyl sulfoxide (DMSO) has become more popular since it has a low level of toxicity, making it a safe replacement for methylene chloride and NMP. Opting for a safe active ingredient like DMSO or a manual paint stripping method will be far safer than risking NMP or methylene chloride.
Removing Paint Without Sanding
Chemical-Free Strippers: Opt for citrus-based paint removers or soy gels, which are eco-friendly alternatives to traditional chemical strippers. These products break down the paint without harsh chemicals and are less irritating to the skin and respiratory system.
Ultimately, whenever you have multiple layers of old paint on your walls you should use paint stripper before attempting to redecorate. If you don't remove the paint that is currently on the wall then the finished look of your decorating project won't be professional.
Scraping paint is done with a combination of tools: a wire brush, a flat metal paint scraper, and a heat gun.

Condition of the Paint
If the paint is in good condition and not in need of any maintenance, it is perfectly fine to skim over it with plaster. However, if the paint is old, flaking, or damaged, it is recommended to remove it before plastering.
Sanding and Scraping: A primary mechanical method, involving the use of sandpaper or an electric sander to weaken the paint's adhesion to the wall. This process is complemented by scraping, using tools like a scraper or a wire brush to remove flaked or bubbling paint sections.
Or anything overly abrasive for that matter. Magic erasers are particularly rough on painted walls because they are chemically abrasive. Even the most durable finishes will come off if you scrub them with a magic eraser. A sponge or damp cloth is more than sufficient for cleaning painted walls.
To use this method, heat 1/4 cup of white vinegar with 1 gallon of water, then soak or saturate the items with the vinegar solution for 15 to 30 minutes. Scrub the paint off gently, then rinse to remove all traces of the vinegar solution and stop the chemical reaction before you repaint.
Pressure washing is one way to remove paint from wood, metal, concrete, and other exterior surfaces. Because of the high pressure levels, it can be very efficient and can drastically cut the time to complete this task.

Sanding. Sanding is one of the most popular methods. It is usually used to help smooth out old paint, remove dry streaks and uneven paint buildup, and ensure that new paint adheres well. In order to remove the paint from wall you can use sandpaper, a sanding block, or a power sander.
Over time, fluctuating temperatures and humidity levels can make paint peel. For spaces where this is normal like kitchens, using KILZ 3® Premium Primer (known for its exceptional adhesion and durability) before you paint can help ensure your paint job lasts longer.
The ability to paint over peeling paint largely depends on the underlying cause of the peeling. If the peeling is due to poor adhesion or surface preparation issues, it is generally possible to paint over it.
