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? You can use a primer to completely cover the old color and then apply 1 or 2 coats of new paint.

For a more accurate color representation, view a color sample or paint color sample in the space you want to paint. The normal green version works great, but if you've recently painted the ceiling or the molding, opt for the delicate yellow version. If the wall is in good condition and the paints are chemically the same (both latex, for example), you have a few options when the new paint has the opposite shade of the old paint. This painting tips article will look at some common situations and provide simple solutions to help you paint your walls, even if they were previously painted in a dark color.

Matt is a professional painter who owns and operates his own painting business, specializing in interior and exterior painting of houses. Oil paint and enamel are too hard, shiny, and latex paint cannot penetrate the drywall underneath. 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. The only way to prevent these stains from seeping through the paint is to first use an oil-based primer.

I recommend cleaning walls first with a damp cloth, but it's a lot of work and I've never done it against a wall that wasn't obviously dirty.
