One precaution: You can't paint with it in cold weather. The chemical reaction that transforms the water solution into a durable finish will not take place if the temperature is below 50°. (Conventional oil paints don't stick well in cold weather, either.)
It's funny, but many of the colors that a paint company puts in its line would never look good painted on any wall. The colors are 100% used to grab your attention when you are perusing paint displays. People are helplessly attracted to bright colors; they are much more eye-catching and far more interesting to our brains.
Cement-water paints are best suited for application to basement walls which are damp as a result of leakage or condensation. To apply these paints, the same procedure should be followed as is described here for painting exterior masonry walls.
Usually on exposed air ducts of galvanized metal a primer coat of zinc dust-zinc oxide paint is used, before the finish coat is applied.
If one has a bleaching or highlighting services done to their hair. The hair will be dryer from the use of bleach, or other lightening products with the addition of developer.

Select the right product. There is a dedicated paint for practically every surface, including tiles and appliances, such as fridges. For high-traffic areas consider scuff-resistant multi-surface paints that can be used on both wood and walls. Kitchens and bathrooms benefit from specialist formulas designed to cope with humidity without flaking.
There are many different kinds of textures, a smooth wall -which is really a "non-texture," will only need to be sanded and the outside edges sponged before painting over it. Hand texture which is easily reproduced by applying drywall compound with a drywall knife and troweling the compound on the patched area to simulate the existing wall texture. A rolled on texture is applied by rolling on some thinned down drywall compound or dry mix that water is added to -the thickness of the compound or dry mix will determine the heaviness of the texture. Some variations of roll on textures have a rough sand granule appearance and both dry mix types can be purchased at most local hardware stores, large hardware depots or at local paint stores, where you will also be able to find spray cans of orange peel or knock down texture. Always make sure to shake the can for a couple of minutes, then test out the spray pattern on a piece of cardboard or scrap sheet of drywall before trying to simulate it on the wall. Orange peel is just sprayed on and left to dry, you will need to experiment so you can adjust the spray nozzle to simulate the texture as close as possible to the size/pattern of the existing wall.
