How do you prepare a previously painted wall for painting?

Use sandpaper or a sanding block to dull any uneven surface, wipe the dust off with a damp cloth and allow it to dry completely. It is necessary to smooth the walls before painting the previously painted surfaces with glossy or high-gloss paint. For pre-painted water-based paints, sand with fine-grained sandpaper. The first thing to do when preparing walls before painting is to patch and fill any holes or gaps with putty.

If you have a large hole, you may need to use a drywall patch and joint compound. I have used patches in the past and they worked very well. For nail holes and so on, I only use putty that turns pink and dries clear, so I know when it's ready to paint or prime. Use an extension pole and sanding head equipped with 80 to 100 grit sandpaper to gently sand walls and get paint.

Using a sanding head on a stick is much easier than sanding with just a sponge in your hand. Sand the walls from top to bottom to smooth the surface. Washing walls and moldings will remove dirt, cobwebs, dust and stains that can prevent paint from sticking. How can I paint on painted walls?

When painting red on white walls, it is best to use a gray-tinted primer, tinted in a shade similar to the red that is used. The best patching material for repairing holes in drywall is the Easy Sand compound (in powder form) that comes in a bag.

Larger holes in drywall anchors generally require two to three layers of compound to mix the patch with the wall.
