What is the difference between water based paint and oil based paint? What are the spraying steps fo

It can be distinguished by material, by ingredient list, by decoration, by use steps, and by quality. The spraying step is to clean up in front first, and then apply the water-based paint evenly on the wall, which must be horizontal and vertical, and can not be mottled.

The composition of water-based paint and oil-based paint is different, and water-based paint only uses water as a thinner, which is more environmentally friendly. And it's very easy to spray.

In home decoration, one of the most important wall decorations when painting, water-based paint has good adhesion, and non-toxic, construction is also very convenient, and even the owner can carry out the construction by himself, so water-based paint is widely popular, today I will first introduce to you the spraying steps of water-based paint and how to distinguish between water-based paint and oil-based paint.

First, the spraying steps of water-based paint.

1. Before spraying water-based paint, it is necessary to check whether there is floating dust and impurities on the construction surface, and clean it up. If there is honeycomb, hemp surface, and depression on the construction surface, putty should be leveled and polished.

2. Apply primer to improve the viscosity of water-based paint. Generally, the primer is applied 2 or 3 times, and each time the coating should be uniform and the thickness should be uniform. Once dry, apply again.

3. Pour the water-based paint into the spray gun and stir it evenly repeatedly. If the consistency is relatively large, it can be diluted with water.

4. Spray the water-based paint in the spray gun evenly on the wall, and be careful not to miss the spray. And when spraying, the thickness should be uniform, so as to avoid the phenomenon of excessive spraying amount and falling.

2. How to distinguish between water-based paint and oil-based paint.

1. Diluent: The main thinner of water-based paint is water, and there are few other thinners. Oil-based paints also include toxic substances such as polyester paint, polyurethane paint, banana water, etc.

2. Toxicity: At present, the sales volume of water-based paint in the market accounts for more than 90%. From the point of view of effect, it is not much different from oil-based paint. The key is that water-based paint is non-toxic, has little air pollution, and is very environmentally friendly, which is the difference between the two.

3. Construction difficulty: the difficulty of brushing or water-based paint is relatively small. Just read the manual, and everyone can spray paint themselves. However, oil-based paint spraying is very difficult, and it is generally done by professionals.

The above is all about the spraying steps of water-based paint, how to distinguish between water-based paint and oil-based paint, I hope it can help you understand the spraying of water-based paint, more decoration knowledge, decoration company evaluation, decoration cases, please continue to pay attention!

Summary. First, the wear resistance coefficient is not the same.

If the paint is not well maintained after brushing, it will fade and peel off the paint after a long time. But water-based paints are different. The surface is very hard after brushing, and there is a certain flexibility, and it will not fade after a long time, but the wear resistance coefficient is slightly weaker than that of paint.

Second, the VOC content is different.

VOCs are chemical compounds that volatilize naturally in the air under normal conditions. The VOC content of water-based paints is ultra-low, but the VOCs emitted by the paint are several times or dozens of times that of the air standard. So we can smell a big smell of paint.

All in all, the higher the VOC content, the less environmentally friendly, so try to choose water-based paint when choosing.

Third, the smell is different.

Many people know that paint has a very choking smell and other odors that are not clear. Nowadays, there are many people in the market who put various spices in the paint and want to pass it off as paint. But the smell of the paint itself is easy for everyone to distinguish.

The smell of water-based lacquer is very mild. Some water-based paints don't smell directly.

What is the difference between water-based paint and oil-based paint spraying methods?

Hello, I'll see you later.

Hello, the difference: the construction is mainly carried out by spraying, which is very simple, and you can follow the instructions yourself. Paint can only be done by professionals or with special training.

First, the wear coefficient is not the same, if the paint is not well maintained after brushing, the phenomenon of fading and paint stripping will occur after a long time. But water-based paints are different. The surface is very hard after brushing, and there is a certain flexibility, and it will not fade after a long time, but the wear resistance coefficient is slightly weaker than that of paint.

Second, the VOC content is not the sameVOC refers to the chemical coating products used under normal circumstances, the chemical coating products can volatilize naturally in the air. The VOC content of water-based paints is ultra-low, but the VOCs emitted by the paint are several times or dozens of times that of the air standard. So we can smell a big smell of paint.

All in all, the higher the VOC content, the less environmentally friendly, so try to choose water-based paint when choosing. 3. The smell is different, many people know that the paint will have a very choking smell and other unspeakable odors. Nowadays, there are many people in the market who put various spices in the paint and want to pass it off as paint.

But the smell of the paint itself is easy for everyone to distinguish. The smell of water-based lacquer is very mild. Some water-based paints don't smell directly.

Water-based paint is no stranger to people nowadays, and you must know its material compared to the environment. However, when carrying out decoration construction, it is also necessary to understand the steps of construction, so that our construction will be very convenient. Let's take a look at itHow to use water-based paint

In this way, it will also be of great help when we are constructing.

First, how to use water-based paint.

1. From the perspective of construction, since the main component of water-based paint is water, it is also necessary to understand that the material used in the water-based paint circulation system must be stainless steel. The general wood surface to be coated should be preliminarily sanded with 200 sandpaper and then sanded with 600 sandpaper to make it smooth and smooth. Joinery workpieces can be sanded directly with 600 sandpaper.

Fine sandpaper sanding will make the wood grain tight and pelletize.

2. Water has high conductivity in construction, so it is also necessary to know that spraying water-based paint and spraying solvent-based paint is also very different, and the automatic spraying system used is also very different. In order to prevent high-voltage static electricity from leaking to the main circulation pipeline, the piston pump is used inside the water-based paint robot instead of the gear pump to disconnect the painting circuit from the main circulation pipeline to prevent danger.

3. It is necessary to know that the indoor construction of winter engineering should be carried out under the condition of trembling heating, and it is also necessary to understand that the room temperature should be balanced, should not be lower than +10 degrees, and should not change suddenly, and a special person should be set up to measure the temperature and open and close the doors and windows, so as to facilitate ventilation and remove moisture. When carrying out construction, it is necessary to have a clear understanding of all aspects. Helps our home.

Water-based varnish construction should be kept ventilated. To prevent mildew.

2. What are the types of water-based paints?

1. There are types of water-based paints. Water-soluble type is water-soluble resin as the film-forming substance, to know the lack of knowledge, represented by polyvinyl alcohol and its various modifiers, in addition to water-soluble alkyd resin, water-soluble epoxy resin and inorganic polymer water-based resin.

2. There are types of water-based paints. Water dilution type Water dilution type refers to the paint prepared by the post-emulsion emulsion for the film-forming substance, to ensure our use, so that the solvent-based resin is dissolved in the organic solvent, and then with the help of the emulsifier by strong mechanical stirring to disperse the resin in the water to form an emulsion, called the post-emulsion emulsion, and the paint made can be diluted with water in the construction.

3. There are types of water-based paints. Water dispersible type Water dispersible type mainly refers to the paint prepared with synthetic resin emulsion as the film-forming substance. We need to understand that emulsion refers to a dispersed emulsion composed of small particle clusters formed by the polymerization of unsaturated vinyl monomers at a certain temperature in the process of mechanical stirring in the presence of emulsifiers.

Lacquer prepared by adding a little emulsion to a water-soluble resin cannot be called latex paint. Strictly speaking, water-diluted paint cannot be called latex paint, and it is also classified as latex paint.

How to use water-based paint is to introduce to you, so that when we carry out decoration construction, we will also understand clearly.
