What’s the Best Way to Repaint Already Painted Walls?

What’s the Best Way to Repaint Already Painted Walls?Its the best way to repaint walls and rooms First you wash the wall by Shampo. it color is water color or oil paint.
Fill any holes and cracks with suitable filler, perhaps using flexible filler for cracks.
Sand and prime the filled areas—priming will seal the filler and keep it in place. You might want to sand and re prime the whole wall to avoid a patchy look.
Repaint the wall with at least two coats of your new color. If you’re painting over a dark color with a lighter one, you might need more than two coats to stop the previous color from showing through. If that’s the case, using a primer or basic white matte emulsion for the first coat (or two if it’s really dark) is a more cost-effective option than using the more expensive colored paint for all the coats. Unfortunately, you don’t always discover that in time.
Finally, paint in full daylight—especially for the final coat—so you can see where you’ve been.Repaint walls and Rooms. this is best way to repaint walls and rooms.

Priming is best. If you have to do two coats of paint to cover the old color, why not use a good primer or primer/sealer and one coat of a good paint? Most people will say otherwise, but primer will stick to old paint a lot better than new paint will. I recommend wiping the walls down with a damp cloth first, but it’s a lot of work, and I’ve never done it to a wall that wasnt’t obviously filthy. Use one coat of primer and one coat of paint. Never ask a paint to do a primer’s job!Priming is best. If you have to do two coats of paint to cover the old color, why not use a good primer or primer/sealer and one coat of a good paint?
