What is used to wash off varnish? What is Varnish?

1. Use cool oil or lard.

If it is an ordinary water-soluble paint, it can be removed directly with water. If it is stained with non-water-soluble paint, you can use our usual cool oil to apply it directly to the position stained with paint, let it stand for a few minutes, wipe it with a cotton ball along the lines of the clothing, and then wash it with water. If the nylon clothes are stained with paint, it is recommended to scrub them with lard and then wash them with laundry detergent.

2. Alcohol or other solvents.

Alcohol is not all paints work, it can only wash off water-based paints, general paints, it is best to use solvents such as solvent gasoline, Tianna water, xylene, cyclohexanone, butyl ester, etc.

3. Kerosene + acetic acid.

When the paint is not dry, it should be smeared with refined oil in time and then coated with dilute acetic acid, and finally cleaned with water to remove it. The paint that gets on the clothes is easy to remove after drying, and it can be removed by heating. Add kilograms of water, 100 grams of alkaline noodles and a little lime to the pot, put the clothes in it and cook for 20 minutes, take it out and wash it with soap, and the paint will fall off.

However, do not use this method for colored clothing.

4. Paint cleaning agent.

When removing the mechanical impurities on the surface of the stone, cover the surface of the contaminated place with the agent and cover it with gauze to prevent the agent from volatilizing too quickly, the working time of the product is 20 minutes and 2 hours, and the part with a brush or a scrubbing machine is scrubbed vigorously.

If the contaminants are not completely removed, the time is extended, if necessary, a few drops of the agent are added to the lesion, rinsed thoroughly with water, dried thoroughly, and the stone is protected according to the procedure to prevent the stone from being contaminated again.

If you get it on your clothes, you can wash it off with gasoline, if you get it somewhere else, if it's on the wall, you can wash it off?

In our understanding of nuclear molds, most of the paints are colored, which are used for decoration and protection. But some lacquers have no color, so let's learn about a colorless lacquer - varnish and its role and classification.

Varnish, which is mainly composed of resin and solvent, is a transparent yellowish paint with a beautiful luster and easy molding. Now it is widely used in daily life, mainly applied to the surface of the object, playing a protective role in the article, and its drying will not affect the original color of the original object, on the contrary, it can also play a good decorative role on the object.

Varnish has its own unique reasons as the most important paint type for on-site construction in home decoration. The varnish is applied to the surface of the object, and after drying, it forms a smooth film that reveals the original texture of the surface. Polyester paint has high requirements for the construction environment and construction process, while varnish is not.

Take the paint tears that often fall in the painting process as an example, the paint tears formed by polyester paint in the painting process are difficult to dissolve once solidified, and the leveling of the varnish is very good, it doesn't matter if there are paint tears, brush again, and the paint tears can be dissolved again. The disadvantages of varnish are that the hardness of the coating film is not high, the heat resistance is poor, and it is easy to turn yellow under the action of ultraviolet light.

Classification of varnishes.

1. Ester glue varnish (also known as water-resistant varnish), this varnish paint film is bright and slow, has a short gloss, is not easy to dry, and can be used on the surface of wood and metal materials.

2. Alkyd varnish (also known as Sanbao lacquer) is easy to dry and form, with high hardness, wear-resistant and scratch-resistant, bright color and heat resistance. It can be used for the protection of outdoor metals.

3. Shellac varnish (also known as bubble water, alcohol fan water, also referred to as lacquer piece), dries quickly, can make the wood grain clear when applied to wood, but it is soluble in water, and is specially used for the decoration and protection of the wood surface.

4. Phenolic varnish (commonly known as Yongming paint), fast drying, easy to form, good gloss, heat resistance, not easy to melt, but the color is yellow, the material is brittle, and it can be used for oily paint as a cover light. 5. Polyester ester glue varnish is made of polyester scraps, rosin, oleic acid, glycerin and other materials mixed and processed, adding a certain amount of drier, it is bright and bright, used to coat the surface of wood, and can also be used as a metal covering.

The role of varnish and the scope of use.

Varnishes can be used to coat furniture, floors, windows, doors and cars. It can also be made into enamel by adding pigments, or colored varnish by adding dyes. It is also used to make enamel and impregnating electrical appliances, and can also be used to fix sketches, gouache sketches, etc., which play a certain anti-oxidation effect and can prolong the preservation time of sketches.

The painted surface is smooth and transparent, showing the original texture of the object, and at the same time preventing oxidation and corrosion, and playing a protective role.

Today's relevant knowledge about varnish is introduced here, although varnish does not have a brilliant color, but it can show the original traces of the surface of the object very well, and it is quite good for the coating of furniture floors.

Just brush it.

When painting, it should be evenly brushed along the grain of the wood, not too thick, and sanded with sandpaper after it is completely boring, until it feels lubricated and stops without protrusions, and wipe it dry after wiping it with a moist soft cloth several times. When the brush is finished and waiting for drying, soak it in water to see if there are air bubbles in the area of the brush, and if there are bubbles, they will burst immediately.

When the brush is dipped in paint, some of the bristles soaked in the paint should not exceed half of the hair length, if the root of the bristles is stained with paint, the paint brush will be deformed, and the service life of the paint brush 4 will be shortened, and the paint brush with the paint must be quietly wiped on the inner and outer surface of the container before brushing, so as to remove the remaining paint and avoid the paint dripping on the ground.

Five steps of painting: 1. Polishing; 2. Scrape putty; 3. Brush the primer; Fourth, topcoat; 5. Polishing.

Inspect wall surfaces and wipe down with a mild detergent if stained. If the old paint film is loose, it needs to be completely removed with a paint shovel; If the wall is nailed or uneven, it needs to be filled with putty and sanded smoothly; Cover furniture, floors, doors and windows with old newspapers or adhesive tape to avoid contamination; Wear gloves, protective clothing and hats; Read the paint oil instruction manual in detail, dilute the paint oil according to the instructions and stir well; Start with the ceiling, then the walls, and apply a layer of primer in order from top to bottom; Reapply both topcoats for best results; Used tools should be cleaned as soon as possible; Undiluted residual oil can be stored in an airtight container for later repairs; Do not pour the leftover paint into the drain casually, it will cause environmental pollution, you can pour the leftover paint on the old newspaper and let it dry before disposing of it.

There are four common problems in painting operations:

1. Hand painted *** or spray painted?

Answer: Some home decoration uses oil mixing process (using blended paint, etc.), for people who do not know much about construction, this practice seems to be easier than varnish, in fact, this construction practice is much more difficult than the varnish practice, and it is a test for the craftsmanship of painters. Workers with poor craftsmanship are prone to brush marks in their work, so in order to improve the quality of the project, many construction sites have recently begun to use the painting process for oil-mixed construction.

The quality of this method is much better than that of manual work, but the disadvantage is that it is more wasteful of materials.

2. How many times do you brush the ceiling and wall paint?

Answer: Generally speaking, if the background color of the wall is relatively light, the ceiling and the paint on the wall can be brushed twice, but if the background color is darker and the paint color to be brushed is lighter, it should be brushed several times according to the degree of coverage of the paint color. However, it should be noted that it is not the more times the paint is brushed, the better, if the number of paint brushes is too much, there will be peeling and cracking.

3. What protective measures should be taken for the hardware when the painter brushes the paint?

A: We sometimes find that when the painter paints, the hardware installed on the wood products (such as door locks, hinges, etc.) is also painted, and as a result, the owner will find that the surface of the hardware is corroded after moving in. Therefore, before painting, painters should put some single-sided tape tape on the parts that are easy to be painted, so as to protect the hardware.

4. How many times is the nitro varnish on wood products generally brushed?

Answer: Since the paint film of nitro varnish is relatively thin, the painter should brush it several times according to the situation, and generally should brush it at least six times. However, there is a premise that the painter should clean the surface of the paint before brushing each coat of paint to avoid the paint covering the foreign matter in the back.

1. To polish, use general sandpaper, you can also ask the seller of sandpaper 2, generally brush two or three times, the first brush is a little thinner, the paint is slightly thinner, the time is more than 12 hours to dry, use a slightly finer sandpaper to polish smooth and then brush the second time, the third time and finally dry thoroughly and then polish with polishing sandpaper.

3. You can use perfume glue.

Painting: The first brush is a little thinner, the paint is slightly thinner, and the time is more than 12 hours to dry.

Polishing it with a slightly finer sandpaper and brushing it a second time, the time is more than 12 hours to dry.

The third pass is more than 12 hours to dry.

Finally, it is thoroughly dried and then smoothed with polishing sandpaper.

You can use balm water.

Be careful to brush with good ventilation.

Close the doors and windows for 2 hours after painting, otherwise it will dry unevenly.

1: According to what you said, it is recommended to use 240 to polish it properly

2: Generally brush 3 times, 2 can also be brushed, the first time to brush well, to be completely dried, in 2 times, the interval is related to the weather and temperature, no matter how to dry to brush the next time, the first side of the brush can be polished, 3: If it is too thick, you can add an appropriate amount of thinner,

When it comes to varnish, everyone should know something from the decoration master. It is often used to paint furniture, floors, doors and windows, etc. As one of the most basic decoration paints, varnish is often used in decoration.

For varnish, you may not know much. SoWhat is Varnish? ?What are some tips for buying varnish?

1. What is varnish.

Varnish, also known as van water, is a coating composed of resin as the main film-forming substance plus solvent. Because both the paint and the coating film are transparent, it is also called a transparent coating. Coated on the surface of the object, it forms a smooth film after drying, showing the original texture of the surface.

Varnish is a transparent or yellowish paint without pigments, with good gloss, fast film formation, and a wide range of uses. The main components are resins and solvents or resins, oils, and solvents. After being coated on the surface of the object, it forms a coating film with protection, decoration and special properties, and forms a smooth film after drying, revealing the original pattern of the object surface.

The varnish is mainly divided into two categories: oil-based varnish and resin varnish, which has the characteristics of transparency, gloss, fast film formation, water resistance, etc., and the disadvantage is that the hardness of the coating film is not high, the heat resistance is poor, and it is easy to turn yellow under the action of ultraviolet light.

Second, varnish purchase skills.

1. Take a look at the packaging. Generally speaking, as long as the packaging is rough, the handwriting is blurred, and the factory address and batch number are incomplete, most of them are inferior products or counterfeit goods.

2. Take a look at the paint surface. When choosing a varnish, you can first look at the quality of the paint surface of the paint sample, usually the adhesion and hiding power of high-quality varnish are extremely strong.

3. Weigh the weight. Lift the varnish barrel and shake it, if you hear the sound of sparse noise, it means that the manufacturer is short of catties, the viscosity is too low, and the packaging has not reached the amount at all. The regular factories are all real materials, and you can hardly hear the sound when you shake it.

4. Take a look at the brand. It is best to buy varnish to choose well-known and reputable brand goods, and the brand products are more advanced in quality and environmental performance. If you buy an inferior varnish, it is simply poisonous.

5. Estimate the dosage. When the user buys the varnish, it should also make a more accurate estimate of its construction amount, and it is best to buy the varnish at one time when purchasing, so as to avoid insufficient dosage; In addition, the varnish purchased successively will generally have a slight color difference, which may affect the painting effect at that time.

The above is the detailed answer about it, I don't know if you are satisfied with our introduction.

Varnish is a transparent coating that is mainly used for the protection and decoration of the surface of wood products。It is usually composed of resins, thinners and additives, etc., which can be formed into a transparent protective film, making the surface of wood products smooth and bright, and can also effectively prevent wood from moisture, deformation, decay and other phenomena.

Varnish is divided into:Oil-based varnishwithWater-based varnishThere are two kinds, among which the oil-based varnish needs to pay attention to ventilation during construction due to the solvent it contains, while the water-based varnish does not contain any solvent, and the environmental protection is better.

In short, varnish is a transparent coating, mainly used for the protection and decoration of the surface of wood products, with moisture-proof, anti-corrosion, anti-deformation and other functions, but also can make the surface of wood products smoother and brighter.
