What are the paints for brushing wood, and what kind of paint is better for brushing wood

Wood oil, alkyd blending paint, alkyd enamel, polyurethane paint, PU, UV and other paints.

1. Clear oil. Clear oil is also known as cooked oil and paint oil. It is a light yellow to brownish yellow viscous liquid made of refined flax oil and other soft dry oils plus some semi-dry vegetable oils, refined and added with an appropriate amount of driers. It is generally used to modulate thick paint and anti-rust paint, and can also be used alone.

On the basis of changing the color of the wood, the original pattern of the wood can be maintained, and the decoration style is natural, simple and elegant, but the construction period is long. It is mainly used as a primer for wooden furniture, and is one of the basic paints for decorating doors and windows, wall skirts, heating covers, and supporting furniture in home decoration. Oil cleaning is more labor-intensive, and at the same time, for projects with high technical requirements, the construction period varies according to the painting area, the complexity of the finish, the type of oil cleaning and the quality requirements.

2. Varnish. Varnish, commonly known as van lishui, is a transparent paint that does not contain pigments. It uses resin as the main film-forming substance, and is divided into two categories: oil-based varnish and resin varnish.

Oil-based varnishes contain dry oils; The resin varnish does not contain drying oils. There are many types of varnishes commonly used, which are generally used for wood furniture, decorative modeling, doors, windows, handrails, etc.

3. Thick lacquer. Thick lacquer, also known as lead oil, is made of slow grinding of pigment and dry oil, with a viscous appearance, and needs to be stirred with clear oil solvent before use. This kind of paint has strong covering power and good adhesion to the topcoat, and is widely used as a primer before painting the topcoat, and can also be used as a surface coat alone, but the paint film is soft and the hardness is poor, and it is suitable for buildings and wooden primers with low requirements.

Thick paint is characterized by self-drying at room temperature, easy to paint and scrape, and convenient construction; The paint film has certain adhesion and mechanical properties; Easy to polish, with a certain back cover, filling performance; However, the paint film is soft, slow to dry, and has poor durability.

In the process of practical application, it should be noted that contact with water, oil, acid, alkali and other substances is strictly prohibited during the construction process; Close the lid of the barrel immediately after use to avoid deterioration and waste; The construction site must have good ventilation conditions, and fire is strictly prohibited.

4. Blending paint. Blending paint is generally used as a finishing paint, which has been blended in the production process and can be directly used for painting in the construction of decorative projects. Blending paints are generally divided into two categories: oil-based blending paints and magnetic blending paints.

Oil-based blended paint is made by adding drier and solvent after grinding dry oil and pigment, with strong adsorption, not easy to fall off and loosen, and durable, but drying and conjunctiva are slow.

Magnetic blending paint is made of glycerin, rosin, dry oil and pigment grinding and adding driers, solvents, its drying performance is better than that of oil-based blending paint, the conjunctiva is harder, bright and smooth, but easy to lose luster and produce cracks. It is suitable for the finishing of indoor and outdoor metal, wood and brick wall surfaces.

5. Nitro paint. Nitro paint, also known as wax gram, is a high-grade coating made by using degreased nitrocellulose soaked in nitric acid and volatilized by the preparation of solvents such as acetone, amyl acetate, and butyl acetate. After drying, it has good luster and durability, and has the advantages of fast drying, hardness, and wear resistance.

It is mainly used for wood and furniture products coating, home decoration, general decorative coating, metal coating and general cement surface coating.

Summary. Pro, it is generally better to use oil-based wood paint or water-based wood paint for brushing wood boards. Oily wood paint will release certain harmful substances after applicing, such as formaldehyde, benzene and other gases, producing a pungent and unpleasant odor, and will cause some harm to the body, while the main components of water-based paint are resin emulsions, pigments and fillers and other substances, which are harmless substances, and make the wood have a better texture after application.

When painting the wooden board, it is necessary to pay attention to remove the dust and stains on the wooden board in advance, so that the surface of the surface can be kept smooth and flat, and at the same time, it is not suitable to apply too thick paint, and strictly control the temperature of the construction environment, so as to avoid defects such as needle eyes or bubbles due to too high temperature.

Water-based wood paint is recommended.

In home decoration, everyone will use latex paint and wood paint, but some workers in the construction of the two types will not have a small impact. So, what should owners pay attention to during construction?

First of all, wood paint and latex paint cannot be applied at the same time. Industry insiders suggest that the wood paint should be brushed first and then the wall paint should be brushed to prevent the ingredients in the wood paint from polluting the wall and making the wall yellow. And the primer on the wall can be more durable, the primer can close the wall base, improve the adhesion of the topcoat, fullness and other effects, not primer brush the topcoat may lead to subsequent discoloration, paint film peeling phenomenon, more worry-free and not cost-effective.

Secondly, the smoother the wall, the better. The use of roller coating treatment of the wall, do not need to pursue the surface is very smooth, the industry recommends the use of short and medium wool roll construction, so that the wall knurling print will look more detailed. Light-colored paint can be applied twice, dark paint can be painted more than four times, and the product will not fall off after brushing several times, but if the putty is damp and loose, it will fall off no matter how many times it is applied.

In addition, the paint that has been opened has a very short shelf life and cannot be stored for a long time, if it cannot be used, it will be handed over to the relevant professional ** department to be poured out (can not be poured into the sewer casually), or it will be temporarily stored in a sealed container.

Third, different places should be painted with different paints. Industry insiders said: wood floors can be painted with polyurethane wood; Wooden crafts are more suitable for nitro paint; Water-based paint ** is high but environmentally friendly, has good performance, and has a wide range of applications.

Moreover, the wood paint needs to be filtered first, and the dust in the air will form small particles after mixing into the wood paint, which will cause particles to appear on the surface of the paint film without filtering, and the surface is not smooth and flat enough.

Latex paint can be used to paint walls, but not wood.

Because the function of latex paint is wall paint, it is easy to fall off if you brush the wooden board, because the stickiness is not easy to separate, and there is no adhesion with the wooden board, if you brush the gypsum board surface. The one that paints the wall is called latex paint, and the one that paints the wood board is called paint, and the two have different characteristics and distinctions.

Wood paint painting process:

1. Plate treatment.

Before painting, the wood should be cleaned and any dust on the surface of the wood should be wiped clean. A special dust cloth can be used for cleaning, and large areas such as floors can be vacuumed repeatedly. At the same time, use sandpaper to polish the surface of the board or wood lines, pay attention to protect the veneer, and do not sand through.

The purpose of board treatment is to effectively remove stains, wood wool and wood thorns on the board, so that the surface of the board is clean and smooth, so that the subsequent painting has a good effect of saving labor and materials.

2. The plate is closed.

The prepared special plate sealant is evenly applied to the plate, which can effectively seal the plate and prevent the plate from being polluted.

The sealing of the plate can prevent excessive moisture absorption, moisture dispersion and deformation of the plate, enhance the adhesion between the paint film and the plate, save the amount of paint, and enhance the hardness of the paint film.

3. Scrape putty.

Select the matching wood putty, and after the mixing, scrape and apply the putty to the wooden eye. After the putty is dry, sandpaper is used to polish and thoroughly clean the putty on the wooden utensils.

Filling the wood holes with putty can reduce the amount of wood paint and improve the flatness of the paint film. Different painting effects have different requirements for the scraping of putty. For example, for an open effect, the putty color should be modulated and the color of the plate should be consistent before scraping.

4. Primer construction.

Adjust the wood primer according to the required proportion, which can be brushed or sprayed. The function of primer construction is to fill the wooden holes and increase the thickness of the paint film.

During construction, pay attention to the primer after drying, it must be thoroughly sanded with sandpaper, and then apply the primer again. It is required to be evenly brushed, no sagging, and the wooden eye is filled flat.

5. Sanding treatment.

Sanding the board with sandpaper is actually a step throughout the wood paint construction process. The plate should be sanded during treatment, the scraping putty should be sanded, the primer construction should be sanded, and the topcoat should be sanded before and after construction. The sanding step is very crucial.

The sanding treatment makes the plate smoother, smoother, and easier to paint. After painting, sanding makes the surface of the paint film smooth and smooth. However, pay attention to avoid horizontal sand when sanding, and do not use too coarse sandpaper.

6. Topcoat construction.

Before the topcoat is applied, the surface of the wood must be cleaned again to remove dust particles, so that the surface of the paint film can have a better coating effect. Every time the topcoat is painted, it is not advisable to brush too thick at one time, and it is best to take the method of painting multiple times, and then do the construction of the next layer after the paint film is dry.

The topcoat construction directly affects the final effect of the paint film, and the topcoat construction requires that it must be evenly painted, no sagging, good gloss, no obvious brush marks, and a smooth and delicate feel.

First, the plates need to be treated.

Whether it is a plate or a floor, there will be a pre-construction treatment and cleaning step before construction. Only by cleaning the dust on the surface of the board can we ensure that the board is smooth and saves paint. Clean the board with a special dust cloth, the area is relatively large can borrow the power of the vacuum cleaner to clean, do not forget to use sandpaper to polish the surface smooth after cleaning, but do not use too much force, pay attention to protect the veneer.

Second, the plate needs to be closed.

The purpose of sealing the board is to avoid contamination of the board, such as excessive moisture absorption or dissipation and deformation, but sealing the board can also increase the adhesion between the paint film and the plate, and save the amount of paint. The sealing plate needs to be sealed with a special plate sealing agent, and attention should be paid to uniformity when brushing, so as to give full play to its effect.

Third, the plate needs to be scraped putty.

It is inevitable that there will be wooden holes in the furniture made of boards, so it is necessary to fill the wooden holes with putty before painting wood paint, which can not only save the amount of wood paint, but also improve the flatness of the paint film. The putty to fill in the blank should be matched with wooden putty, and the prepared putty should be scraped into the wooden hole, and then sanded with sandpaper after it dries, and finally the putty on the wood should be cleaned.

Fourth, the plate needs to be primed.

The purpose of brushing the primer is to fill the wooden holes and increase the thickness of the paint film, and the primer can be adjusted according to a certain proportion, either by brushing or spraying. During construction, it is necessary to wait for the primer to dry and then thoroughly polish it with sandpaper, and apply the primer again, so that it can be evenly brushed without sagging and unevenness.

Fifth, wood paint painting.

Before applying wood paint, clean the surface of the wood product once to prevent dust particles from falling on it. Every time the wood paint is painted, its thickness can not be too thick, and the wood products should be painted by multiple brushes, and each paint must wait until it is dry before the next paint is constructed.

Wood needs to be protected by paint, now there are many paint brands, if a good paint can make wood not damaged, it is not easy to damage the material of wood, many people sell paint regardless of the brand, in order to figure the quantity, do not pay attention to quality, so there will be some fake and shoddy products, after such shoddy products appear on the market, the harm is still the purchase of users, so there must be certain standards and principles when choosing wood paint, the following will tell you in detail how to do a good job in wood paint selection.

First of all, the wood is insecticidal, and then the wood paint used for wood products is selected, including polyester, polyurethane paint, etc., which can be divided into water-based and oil-based. According to the gloss, it can be divided into high-gloss, semi-matte, and matte. According to the use, it can be divided into furniture paint, floor paint, etc.

A, identify the brand or formal and powerful dealers, paint and coating products are not only related to the beauty and comfort of the living environment, but more importantly, related to the health of the family, can not be sloppy. The products operated by regular dealers are all regular brands with quality in line with environmental protection standards, and they have many years of experience in using products. For the sake of its own long-term development, it will never do anything that harms consumers.

b. Pay attention to product matching. Bottom paint, top coat, etc., can not be bought or less because of the high price of such things, but should be comprehensively considered by the oil carpenter master to demand the quantity and the suggestions of the shopping guide, and then purchase.

c. Carry out anti-counterfeiting inquiries of products. Nowadays, big brands generally have anti-counterfeiting query systems, so consumers don't feel that they have spent a few cents on the query fee or wasted ten minutes of time.

d. Carefully understand the after-sales service of the brand. After clarifying the after-sales service content of the brand, decide whether to purchase it.

e. When the master is constructing, pay attention to smelling the smell. If the smell is not foul or particularly weird, if it smells aromatic, it is recommended that you pay special attention to whether it is a highly toxic substance; If it is polyester paint, nitro paint paint is recommended to just feel it, if it is water-based wood paint, you can stay freely in the room during construction, because water-based wood paint will not cause any physical harm to the builder.

If you need to buy wood paint, you can refer to the above principles, because the above steps have been very clearly explained, if you want to make the texture of the wood material not damaged, and make the wood appear more shiny and translucent, you should choose the best glossy paint, do not try to buy fake and shoddy products cheaply, users must polish their eyes when buying wood paint, do not be blinded by the unqualified paint in front of them.
