The paint door generally refers to the wooden door on the surface of the paint. I don't like to call the 'painted' door, because this is a hype word. The door factory that really uses 'painting' is no more than 1%, basically it can't be bought. . Of course, this does not hinder the beauty and strength of the 'paint' door; because the paint used on the wooden door is mostly PU polyurethane paint, it is chemically cured, but it does not need to be 'baked', but it only sounds stronger when it is roasted. abuse. Here is the first clarification.
If you have the same bottle of good wine, time will not take away the wine. A good paint door can preserve and add value with the house, which is the biggest advantage.
Paint has two functions: First, it provides a protective layer to protect the wood underneath. Now the PU paint is tough, scratch-resistant and waterproof. The second is decoration. The simpler is the transparent effect, which reflects the natural wood grain underneath, because the surface of the wood is actually uneven, and the transparent paint layer can reflect the 'quality' of the wood. From different angles, the wood grain will be presented. Different effects will be 'live', which is not a substitute for printed flat grain paper. Other decorative effects are more complicated, with an open leaking wood grain effect and a mix of colors.
The disadvantage of paint doors or 'painted' doors is that the price is higher, especially good wood doors are more expensive. Ordinary composite paint doors are not cheap. But the thing on the facade is still the flower. Another shortcoming that will be mentioned is that it is easily deformed, but it has nothing to do with the paint. The key is to keep the room ventilated and the bathroom and toilet as dry as possible (see the post "How to prevent wooden door deformation?").
Another disadvantage is that the delivery time is long, because it has to be painted, polished, and painted. ,. The composite door usually takes one month, and the original wooden door may take two months. It is not suitable for some owners who are rushing to 'schedule'.
The paint-free door generally refers to the PVC door and melamine door on the market. The biggest advantage is that it is cheaper than the paint door. Just like beer is suitable for the public taste, of course, you have never heard of the 'Beer 1981 beer bar'. The PVC mask is relatively soft, not very scratch-resistant. If it is scratched, it will not be repaired. The surface of the melamine panel is very scratch-resistant. Similar to the laminate flooring, it is an upgraded version of the PVC door. The surface of these doors is very 'waterproof', but The side of the door always has a gap, which is the easiest to crack around, so you can't abuse the 'waterproof' function.
Because it is a batch molding type, the wood grain is often in one direction, and the pattern is also less and cannot be customized. Of course, the paint-free door is mostly for second- and third-tier cities and middle and low-end projects, and the price is a killer. If there is propaganda that the paint-free door is formaldehyde-free, it is nonsense. Although there is no paint and there is little glue, the wood-based panels (density board, plywood) inside contain absolutely formaldehyde, and the content is not low. In general, the selling point of the paint-free door is low price and short delivery time.
