Looking to refresh the color on your home's walls? A lot of people are asking if it's OK to paint over dirty walls. The answer is that you have to thoroughly clean your walls before painting. Follow this 4-step process to prepare your walls for painting and make their color last over time: Use a sponge, light washing liquid and warm water. For kitchen walls exposed to oil or grime, wash the walls with dish soap poured in water and after that follow up with just clean water. Lastly, wipe the walls with a damp cloth and wait till they dry out. Wear your gloves and safety glasses and wash any spots covered by mildew. Scrub the damaged area with a sponge, 3/4 of water and 1/4 of bleach. Wait for a few minutes and rinse the wall with clean water. Sand the wall's surface to smooth it before painting. Utilize sandpaper to dull any uneven surfaces and after that clean away dust and debris with a small cloth. Allow it to dry before you start painting. Use a primer for an uniform coating!
