What is open paint and what is the difference between it and general paint?

Open lacquer is a kind of wood coating process relative to closed lacquer, which is a popular process in high-end furniture in Europe in recent years. Open paint is divided into full open and semi-open. Also known as water whitewashing.

Fully open paint: its main component is polyurethane, the concentration is relatively small and the wood hole is obvious, the texture is clearly visible, the paint coating amount is small, and it can also be repaired twice. In fact, open paint has nothing to do with paint in general, open paint refers to a process, and paint is a physical thing.

First of all, let's talk about the sealing paint; As the name suggests, closed lacquer means closed with lacquer; The sealing primer plays the role of sealing the pores of the substrate and the fiber catheter, which is film-forming and gelatinous, and it is difficult to sand. Rare points of general tone. The viscosity is still high.

The second primer is generally thicker, which is easy to polish and smooth, so the consistency point is generally adjusted. The transparency of good polishing is almost good, and the polishing of good transparency is slower. Therefore, the two-penny paint is divided into two categories: solid wood bottom (easy to sand) and sticker bottom (good transparency) According to the different production processes of manufacturers, the number of times of painting will be different.

Therefore, sealing paint is a painting process in which the brown hole of the wood surface texture is completely closed by the paint, which is manifested as the paint film on the surface of the wood substrate is plump, thick, bright and smooth, and the sealing paint can be suitable for all wood substrates. Next, let's talk about open paint; For an explanation of the noun, please refer to the sealing paint above; Open lacquer refers to the ability to see the natural characteristics of the wood grain, just to change the color, which is a common finishing method in European and American countries, that is, the wood is colored with a water-based color paste on the treated substrate, and then sanded, primed, and then applied with a transparent topcoat. The basic process flow is as follows:

Sanding--Primer--Sanding--Bottom Coloring--Second Primer--Sanding--Face Finishing--Top Coating However, open paint is overly dependent on the texture of the original wood matrix, so it is relatively strict and harsh in terms of material selection. Therefore, open paint is a kind of spray painting process that completely exposes the brown holes of the wood surface texture, which is manifested as obvious wood holes, clear texture and strong sense of nature, but its cost is high and the spraying technology is high. Generally speaking, to make open lacquer, the brown holes of the wood must be deep and obvious, such as oak, ash, etc.

Sum up; The main difference between closed and open is the substrate of the wood. In the case of the same substrate, the opening and closure of the wood conduit is mainly the construction amount and solid content of the paint, generally speaking, nitro is the best effect when used to open the wood matrix, PU needs to be diluted, and it is difficult for PE to be used to open the wood matrix. On the contrary, the effect of enclosed furniture is the best, the effect of PU needs more than 3 times of primer, and the effect of nitro is very poor, it is difficult to fully enclose, at most semi-enclosed.

Open lacquer is divided into full open and semi-open. Also known as water whitewashing. The principle is to preserve the pores of the natural wood and highlight the sense of mechanism.

If the pores are completely covered, it is an ordinary sealing process. If the wood is soft, you can also use a hand brush, such as fir wood. If the wood is hard, it must be painted.

Not all woods are suitable for open lacquer, such as woods with inconspicuous pores and wood grains. 7F surface open paint is a popular process in European high-end furniture in recent years, which is manifested as: obvious wood holes, clear texture, less paint coating, matte, natural, strong texture, and three-dimensional touch.

The surface open paint effect process is difficult, and the use of modern machinery can not fully reflect its effect, so Xinweisi adopts the bottom rubbing process. The bottom wiping process does not use modern mechanical spraying, but uses manual wiping to treat the furniture with color paste and paint. The process can ensure that the color paste is firmly attached to the surface of the veneer, and can be synchronized with the wood when the temperature changes, and the wood can be synchronized with the thermal expansion and contraction, and the second can make the wood grain bright color, outstanding texture and natural, and at the same time, the color paste and paint directly penetrate into the wood eye, which is not easy to fade and not choose the color.

Open paint is essentially not much related to lacquer, mainly the problem of construction, and the problem of the board, only the board with a deeper texture can do open paint, there is a transparent color, there is a transparent color, there is an opaque white or color, but these paints are ordinary paint or polyester paint, can do open paint of the board is generally more ash willow, in the autumn wood, the wood is also OK, but the texture is clear. Because you can't fill the texture, you have an open effect. However, it is easier to make open paint than to close it.

Many people will hear the term open paint when decorating, and today PCHOUSE will introduce to you what is open paint.

Paint retains the pore structure of natural wood grain and is able to accentuate its texture, which is a coating process. There are two classifications of open paint, which are open and semi-open.

The main ingredient of open paint is PU, and its coating effect has a clear texture, obvious wood holes, and a matte texture. Visually, the open paint retains the natural pores of the wood, making it more natural and can be held for secondary repairs. However, the disadvantage of open paint is its higher cost and higher spraying process requirements, it is difficult to form at one time, and it needs to be sprayed about ten times in many cases.

Semi-prudential source open paint has also become popular in recent years. It combines the advantages of open paint and closed paint, which not only retains the original natural wood feeling, but also reduces costs and environmental pollution.

Open paint and semi-open paint are not all wood filial piety can be used, the specific should be decided according to the structure of the wood, such as the delicate texture of the wood, like maple wood is only suitable for closed paint, otherwise it is suitable for open paint. Only woods with large internal holes, such as oak, ash, oak, etc., can be applied to open lacquer.
