Paint Scratch
If you've ever gotten a scratch on your nicely painted wall, then you know what an eyesore it can be. Instead of painting the entire wall for one small scratch, try using some touch-up paint techniques. Using the right techniques, no one will ever know you scratched it in the first place.
Preparation
Before you apply touch-up paint to the wall, prepare the wall so that the paint will blend in. If the scratch is deep, you should fill it with spackle. Use a spatula to press the spackle into the scratch and smooth it out. Allow it to dry and then sand it lightly so that the spackled area is level with the rest of the wall. If it is only a surface scratch, you can sand down the edges of the scratch so that it's completely smooth.
Paint
Before you apply the paint to the wall, be sure that you have the right color. That's why it's always a good idea to keep cans of paint from remodeling, so that you always have touch up paint on hand. If you don't have your original paint can and can't remember the name of the color, bring a small sample of the paint that has flaked off to the hardware store where you purchased it. Employees there should be able to match the color with their computers so that you get a seamless touch up.
Application
When you have the right color and the area has been sanded down, apply the touch-up pain. Begin directly on the scratched area, and use a broad paintbrush that can force the color right onto the affected area. Then, use a small, textured roller to feather the edges of the new paint into the old paint, blending one into the other. The paint on the textured roller will fade the farther from the patch you go, making it almost impossible to detect. Add a topcoat if necessary.
