Before painting, it is best to use sandpaper to polish the surface of the anti-theft door, first, to remove part of the background color, and secondly, the smoother the surface, the easier it is to paint; Don't worry about rust prevention, it's a big deal to spray twice to increase the thickness of the paint film. 2. Try to choose the anti-theft door sprayed during the day, the light will attract small insects at night, and the paint that has just been sprayed is easy to stick to insects. 3. Protective work should be done well, hats, masks, gloves, and work clothes should not be missing; And it's better to let someone with glasses squirt; We're still in a tight position - the shoes are covered with a lot of white paint.

4. Be sure to strictly follow the instructions for use, use a small number of times, spray a thin layer every three or five minutes, if the paint area is about two square meters like my anti-theft door, a bottle of 400ml can be sprayed about three times, the effect is much better than a one-time full spray. Don't listen to the business, a small bottle (400ml) can indeed spray more than one square of the security door, but this can not cover the background color of the security door, especially the light cover dark case, basically each square needs about 1 liter to achieve a satisfactory effect.

In strict accordance with the instruction manual, a small number of times, according to the frequency should generally be 3 5 minutes to spray once, pay attention not to spray too thick, if the anti-theft door is almost two square, then such a painting area is calculated, a bottle of 400ml can be sprayed about three times, so that the intermittent painting method is much better than the one-time spraying effect;

On the one hand, the paint can be dried quickly and naturally, on the other hand, if it is sprayed at night, the light will attract some small insects, which are easy to stick to the paint surface, affecting the aesthetics and effect;

Although 400ml can indeed spray about a square, but it is still necessary to consider what material to spray on, because according to this, it is impossible to cover the original color of the anti-theft door, especially when the background color of the anti-theft door is relatively dark, if you want to spray light-colored paint, you basically need to spray 1 liter on 1 square to achieve a good effect;

Before painting, the door should be sanded with sandpaper, the smooth surface is easier to paint, and the dark color of the anti-theft door can be removed from part of the background color, if you are worried about the rust of the anti-theft door, you can spray it several times to increase the thickness.

The outfit should be prepared: hat, gloves, overalls, and gloves, and don't forget to bring your eyes when spraying to prevent splashing, and wear shoes that you don't usually wear or old shoes.

Certain protective measures should also be taken for the door, pay attention to protect the hinge, door lock and other hardware accessories, if necessary, you can also remove the door, and take off the hinge and door lock in the painting, so as to ensure that the accessories are not covered by spray paint, to avoid affecting the aesthetics.

The security door can be repainted, there are no special requirements for the painter's technique, but a special spray gun is required, and the specific operation steps are as follows:

1. Prepare the security door and hang the two corners of the security door.

2. Use a spray gun to start spraying, starting from one side to the other.

3. Spray paint one side of the security door.

4. Turn the security door over.

5. The anti-theft door is reversed to the other side and ready to be painted.

6. The same method starts painting from one side to the other.

Hello, dear, is it better to paint the entrance door independently or brush, and it is better to spray paint independently, for the following reasons: 1. The brush is the first of the cluster to use the brush for construction, which is a plane effect, but the brush will leave brush marks. Spraying is a simple stove method using a spray gun, with a smooth surface, excellent hand feel, and good fullness, which can be said to be the best plane effect.

2. Painting: The painting machine is more expensive, and the general painter is not equipped. The advantages of spray painting are:

The construction is fast, the flatness is good, and there is no poor texture. The disadvantages of spraying paint are: large paint loss, post-maintenance trouble, because in the later maintenance, workers can no longer pull the painted machine to repair, can only use a brush to brush, brushed out and sprayed out of the texture is definitely different.

3. Painting: The construction is relatively slow. However, the paint surface has a rolling texture and pattern, which is easy to maintain.

The disadvantages of painting are: the effect of large-surface roller coating is different from the whiskering in the yin corner and the lamp trough, and there is a difference in texture. The loss of lacquer is relatively large, and it is not particularly affordable.

4. The coating surface of the spray paint is smooth, the hardness is high, the cleanliness is good, it is easy to clean, and it has the feeling of a color board room. The advantages of brushing paint are matte, soft color, good air permeability of the coating, and low cost.

Just spray the paint directly on the security door.

No matter what kind of paint is sprayed, it is recommended to work in the paint room. On the one hand, it is environmentally friendly, and on the other hand, it is to reduce dust and achieve the best paint effect.

The so-called metallic paint is added with a certain amount of aluminum powder and pigments, and the size and arrangement direction of the aluminum powder particles determine the appearance of the reflective effect. Because the car is sprayed electrostatically in the factory, the aluminum powder particles are arranged consistently.

When the metallic paint is repaired by hand in the future, if the technology is not up to standard, it is easy to appear flowering.

"Metallic paint" because the paint is mixed with metal powder, which can not only make the surface of the painted car look more shiny, but also at different angles, due to the refraction of light, the car color and even the outline will change, which is why "metallic paint" will be more and more commonly used.

Metallic paint has a metal component, so the hardness of the paint increases, and the paint surface hardens, so it is not easy to be scratched.

Plain paint is a paint that does not add metal powder, and the hardness of the paint surface is relatively soft, so it is easy for the paint surface to peel off when it is hit by flying stones on the road surface when driving at high speed. When cleaning the car with plain paint, you must not wipe it directly with a dry cloth or a damp cloth, and you must definitely use a lot of water to wash off the dust on the surface of the car paint, so that the hard gray sand will not scratch the car paint as soon as the rag touches the car body.

Generally, the anti-theft door baking paint category is divided into indoor paint and outdoor paint.

There are too many small categories, and the general wood grain uses red thermocoagulable powder, which is then baked at high temperature and then converted to a printing type. Then there are metallic paints, anti-copper (anti-copper and red copper, bronze (bronze), etc.) these are all colors.

Plain colors include black, gray, white, blue, green, coffee, etc!!

If it is the kind of paint that uses the car, the price will be more than 100 more expensive for a door!!

Generally, outdoor paint is only slower than indoor paint, and the color change and aging rate are slower, while car paint can almost be said to be rainproof and sunproof!!

The security door can be re-painted for the painter.

There are no special requirements for the technology, but a special spray gun is required, and the specific operation steps are as follows:

1. Prepare the security door and hang the two corners of the security door.

2. Use a spray gun to start spraying, starting from one side to the other.

3. Spray paint one side of the security door.

4. Turn the security door over.

5. The anti-theft door is reversed to the other side and ready to be painted.

6. The same method starts painting from one side to the other.

7. Both sides of the anti-theft door are sprayed with paint.

It can be repainted, first sanded with coarse sandpaper and then cleaned, supplemented with putty and then polished, sprayed primer polishing spray topcoat water grinding and then spraying topcoat is perfect. The painter's skills are required, and the paint job is the fine grinding ......

If you don't think it's ugly to spray, then you can spray it, and the automatic painting effect of any brand can't be compared with the car paint in the middle. One is that the brightness cannot be reached, the second is that the hardness cannot be reached, and the third is that it is not wear-resistant.

It is recommended that it is best not to respray the paint, if you really want to spray, you need to scrape off the original paint, and you can't scratch it.

The anti-theft door can be repainted, but it will definitely not be bright, and it is easy to peel off the paint.

If you spray, there is no technology, clean up the low-level old paint, and grind it smooth, and then rinse the anti-rust paint at the bottom of the layer, I hope to spray it on the surface, spray it freely!

Hello Kiss Your question, here is the answer to your question: it is recommended to use fluorocarbon paint, not easy to drop, the price is not expensive, as for the color, the anti-theft door should be brushed with a darker color, which appears more stable, that is, dark red or other colors. If it is repainted, you should first use a metal shovel to shovel off the rust on the door, and then use sandpaper to polish the door until it is smooth, and then brush a layer of anti-rust paint with a paint brush after polishing, and then brush the paint after drying.
