Prepare and adjust Spray gun

Spray guns and related equipment should be clean and in normal working order prior to spray application. Check that the spray gun produces the desired spray pattern. The ideal spray shape should be symmetrical with uniform spray particle size distribution and sharp edges with only a small amount of paint mist outside the edge of the spray shape. Low atomization pressure helps produce a correct and uniform spray pattern, reducing bounce and overspray.

Hold Gun correctly

Properly sprayed tracks are perpendicular to the work piece surface. Spraying according to be coated surface angle, the distance between the spray gun and the spray surface is generally 15 ~ 30cm. To get wetter, darker-colored and thicker coatings closer to each other; to get drier, lighter and thinner coatings, the distance can be further.

Walk the gun

Guns include the spray gun on the surface being coated and the speed of the gun. Spray gun should be kept at right angles to the surface being coated, parallel operation. Gun speed is generally 30 ~ 60cm / s between the adjustment, and requires constant. If the spray gun is inclined and arc-shaped operation or changing speed, you can not get a uniform thickness of the film, and easy to produce stripes and marks; spray gun operating speed is too slow (30cm / s below), then easy to produce sagging . Adjacent spraying trip should have a lap, that coincidence rate, coincidence rate should reach 50% -60%. Too fast or lap when not easy to get a smooth film. When the uniformity of paint thickness requirements, should be used the cross-spray method, then do horizontal spraying.

New car hand, the most vulnerable is the paint. Careless car wash, paint will be injured. In fact, there is damage to the paint even when it is loaded on the production line. Small general abrasions, paint surface scars, scars whiten. That is the surface of the paint was shaved. There is no need to paint Light, beat with sand wax or wax several times. Heavy, polished it.

Seriously, you can see the color of the primer (often, the primer is dark). Well, please take a look at the wounds. In general, the bumper, rearview mirrors and some car wheel eyebrow these parts are plastic or stainless. Ugly is not a big problem. It does not matter to fill up the paint down. Others, it is necessary to fill the paint, otherwise, even if it is a small damage, the steel will begin to rust, you can grind the rust with a grinder, then epoxy primer (rust), and then scraping Tu putty
