What do I need to do to prepare my wall for painting?

Before painting over a wall that has existing paint and patches of skim coat, you'll need to prepare the surface properly to ensure the new paint adheres well and gives a smooth and even finish. Here are some steps you can follow: Clean the wall: Use a sponge or cloth to wipe down the wall and remove any dirt, dust, or debris. Fill any gaps: If there are any gaps or holes in the wall, fill them with spackling compound or joint compound. Use a putty knife to apply the compound and smooth it out evenly. Wait for the compound to dry completely before proceeding. Sand the wall: Use sandpaper to smooth out any rough patches or bumps on the wall. Sand until the surface is even and smooth. Wipe away any dust with a damp cloth. Prime the wall: Apply a coat of primer to the wall to help the new paint adhere better and give a more even finish. Let the primer dry completely before painting. Paint the wall: Apply the new coat of paint to the wall using a roller or brush, starting from the top and working your way down. Apply a second coat if necessary. If the paint on the wall is in good condition and not peeling or flaking, you may be able to skip the step of sanding the wall. However, if the surface is uneven, it's important to sand and prime the wall to achieve a smooth and even finish.

Remove and start all over again it’s never going be be the same if not

You need to thoroughly wash off any wall paper glue residue then if all flaking paint has been removed, you could paint on filler coat to iron out imperfections. Any deep impressions need an interior wall filler. To get a smooth finish use a calking trowel.

A few tips: - Ensure the wall paper adhesive is all gone - wash it off with a strong Sugar Soap solution. - Then, use some 120grit sand paper and ensure all the flaky stuff is really gone. - With your patches of skim coat, I would prime these with a diluted coat (mist coat) of your chosen paint. - Give the wall a final dust and wipe down with a damp cloth. The more preparation you do, the better your finish will be.

Hi this is Michael , Airless HVLP specialised on MDF unit spray painting skill, It's great that you have removed the wallpaper and peeled off the flaky bits of paint from the wall. However, before applying a fresh coat of paint, there are a few additional steps you should take to ensure that the surface is properly prepared. 1. Clean the surface: Use a damp cloth or sponge to clean the wall of any dust, dirt, or debris that may have accumulated. 2. Fill any holes or cracks: Use a suitable filler to fill any holes, cracks, or imperfections in the wall. This will help to create a smooth and even surface for painting. 3. Sand the surface: Use sandpaper to smooth out any rough or uneven areas on the wall. This will help the paint to adhere better and create a more even finish. 4. Prime the surface: Apply a coat of primer to the wall before painting. This will help to seal the surface and provide a good base for the paint to adhere to. If the existing paint is in good condition and is well-adhered to the wall, you may be able to paint directly over it without removing all of the existing paint. However, if the paint is flaking or peeling in larger areas, it's best to remove it completely to avoid any issues with the new paint adhering properly. In summary, to prepare your wall for painting, you should clean the surface, fill any holes or cracks, sand the surface, and prime the surface before applying a fresh coat of paint. If the existing paint is in good condition, you may be able to paint over it, but if it's flaking or peeling, it's best to remove it completely.
