What should I prepare to change the red gate of pig liver into the color of high-grade ash?

The most direct way to change the door is to change the door. There are many kinds of security doors on the market, and there are also many excellent products in appearance design. Of course, we can choose not only "dark red". You can solve the problem from the root by directly choosing your favorite shape and color. But before changing doors, we need to consider three questions:

1. Ask if the property is allowed to change doors. Some houses have ceramic tiles in the corridor, which may be refused by the property owner to change the door privately on the grounds that the corridor wall cannot be damaged.

2. Look at the security level of the security door. There is a sign inside the door frame. You can see it when you open the door.

This level can be divided into four levels: "A, B, C and D", and the security decreases in turn. If the door of our house is already Grade A, it is recommended not to replace it, which is a bit wasteful-local tyrants are free.

3. When replacing the security door, the construction must be carried out before the hydropower transformation is completed. In the process of changing the door, it will definitely cause damage to the wall, so that these damages can be repaired in the future decoration.

Felt The most popular security door decoration at present is felt, and the effect of sticking it out is probably like this ▼

Felt has two advantages. First, it can enhance the sound insulation effect of the security door. Second, it can enhance the heat insulation ability of the security door. However, the felt door is tight:

1. After all, the surface of the door should be as flat as possible, and there may be several concave shapes, but there must be no convex shapes. No matter what shape it is, it will flatten after being stuck with felt.

2. The edge of the door lock must be as square as possible and can have a relatively small arc. But don't have too many complete edges, which will make you collapse in the process of sticking the felt.

The felt with rough surface of textured paper is very easy to accumulate dust during use, which is difficult to take care of. If you want to keep the door panel smooth, you can choose textured paper. After pasting masking paper, the original shape of the door can be maintained, but the color and pattern are changed. In the process of pasting masking paper, there are also precautions (if it is not pasted well, it will become like the following figure):

1. The construction of textured paper is rather troublesome. You need to stick the textured paper on the door first, and then heat it against the textured paper (just blow it against the blower). After heating, the textured paper will become soft and perfectly match the concave-convex shape on the security door.

2. The replacement of textured paper is quite complicated. First, it is not easy to tear off. Secondly, even if it is torn off, a layer of glue will stick on the door.

3. Why do you want to tear off the textured paper? Because the textured paper is not strong, after bumping, the surface of the textured paper will be damaged, leaving small pits.

Direct painting can also change the color of the security door. It's just that this structure is professional, and it may be difficult for users to operate it themselves:

1. When selecting paint, look for paint. Latex paint is commonly used in our decoration, which has poor adhesion and cannot be painted on smooth metal doors. If you want to buy paint, it is the kind of paint in automotive sheet metal-paint is not environmentally friendly. Try to choose paint with high environmental protection level.

2. Polish the security door before painting. Polished until the surface becomes rough, just shake hands a little. In the process of grinding, we must keep the surface smooth, and we can't grind it higher than one.

3. Paint can be sprayed or brushed. Spraying requires professional tools, and the effect is that the surface is grainy. Brush tool is cheaper, and the effect is flat and smooth.

4. No matter what kind of construction method, you need to brush (spray) at least three layers. Between each painting, the interval should be at least 12 hours (the picture below shows the effect after the first painting) ▼
