- If you decide not to use mechanical surface treatment, and use a special washing, then proceed with extreme caution not to poison yourself, since its pairs are very toxic. This phase of work is very important, because if you miss it, then later the paint under the influence of precipitation and temperature changes will begin to flake off, and you need to repaint garage door.
- To maximize coupling with the surface, it needs to be sanded with fine sandpaper.
- Degreasing the surface. After cleaning the surface from the old paint, you should degrease it. During processing, it is important to capture the entire surface, including hard for reaching areas. The final result depends on how well you do this.
- Primer application. The next step is applying on the gate three thin coats of primer, intended for metal surfaces. After application of each layer, wait for a while to allow it to dry. Due to this action, the coupling of surface with paint will be much better. The primer is necessary not to tone the surface, but to make better the paint adhere to the metal. Thanks to primer, the enamel layer becomes smooth and even acquires a finished look.

- Roller. It provides paint distribution and makes strokes invisible, but many places for roller are unavailable. Often the method is practiced, in which both brush and roller are used. In this case, the painting turns out better.
- Spray gun. This method is good for those who know how to use it. It is very important to choose the viscosity of paint, necessary air pressure and to be familiar with the gun control, as well as apply paint without sagging. So if you have absolutely no skills of such work, just use a brush or roller.

- Pay special attention to hard for reaching places, corners and edges, for their staining use a contour brush.
Important: perform all these processes only at temperatures from +50 to +68 F degrees. Failure to comply with temperature control may bring problems with the paint dry:
- uneven color.
