If you're going to remove the paint by hand, you'll first need to wash the wall with soap and water. You can then apply a sanding block, an electric sander, or a wire brush to the wall to weaken the paint. Once you've weakened the paint, apply a scraper to remove sections with scales or bubbles. Apply a protective cloth to protect the floor from the stripper.
Dip a brush into a can of stripping gel. Use gel instead of liquid stripper because they won't drip onto the floor. Choose a stripper that works for acrylic or latex paint. Don't try to sand the paint on the walls if you suspect that the paint is old and that it might be lead-based.
Lead-based paint was used before 1978 and can be toxic if sanded. Try to remove scaly, peeling paint from the wall with a solitary scraper. Put a dust mask on your face before removing the paint and drag the blade with moderate to firm pressure in all directions under the paint until the wall is bare. If the scraper didn't work or you'd like to reduce the processing time, use a liquid paint softener stripper.
Put on sturdy rubber gloves and follow the instructions. Heat Try a heat gun, torch, or iron if you prefer not to use harsh chemicals. Wear a respiratory mask to avoid inhaling vapors when removing paint, and be sure to ventilate rooms with exhaust fans. With one hand, apply heat to a section of the wall from a few inches away, shaking the heater back and forth.
When it starts to bubble, use your other hand to scrape off the paint with the scraper. Sand techniques, such as scraping and peeling, require a lot of patience and a bit of muscle. Let a power tool do the work for you. Buy or rent an electric orbital sander with 40-grit sandpaper.
Place a cloth or canvas over any nearby appliance or furniture and open a window to ventilate, as the sander creates a lot of dust. Put on a mask and goggles, and sand the wall section by section. Alternatively, if you want to remove paint from plaster walls, coat the paint with a full coat of chemical stripper. It is painted with a brush, laminated paper is applied, and then the paint and paper are removed with a plastic spatula.
If you want to repaint the wall, follow the instructions on the stripper to neutralize the wall and not damage the new paint. If you don't want to use professional stripping products, you can create your own homemade stripper; this will take a little longer, but if you have all the ingredients anyway, it will save you a trip to the store. Scrape off the paint with a paint scraper or an oscillating tool with a scraping attachment and discard it. This is fine if the wall doesn't already have a lot of paint and if the old paint layer is in good condition.
If you want to remove the paint completely, instead of painting on it, you can use a paint scraper to remove any remaining paint. If the paint hasn't loosened on its own over time, you have no choice but to use chemical strippers to loosen the paint. If you find any evidence of irregularities or flaws in the paint, the best thing to do is to remove the peeling paint from the walls by scraping it and removing anything that is loose. If you decide to remove peeling paint from your walls with a remover or stripper, a good option is the Dumond Smart Strip advanced paint remover.
Use painter's tape, washcloths, and any other painting tools you need to paint a room without making a mess. To remove paint from drywall, start by cleaning the wall with hot, soapy water to remove dirt or paint marks.
