What are the precautions for the use of water based industrial paint

1. Spraying tools, mixing containers, mixing tools, etc.: do not mix with paint tools, spray guns for spraying paint require 2 times of thinner material, 2 times of dish soap water, and 2 times of clean water before spraying water paint;

2. Water paint spraying requirements for substrate: substrate treatment is consistent with spraying paint requirements, shot blasting grade, no dust, no oil stains, if the substrate has oil stains, the oil stains need to be treated with Birnick water-based degreasing agent; Spraying on the original paint surface requires brushing treatment;

3. Temperature and humidity requirements: when the humidity is greater than 75, the temperature is lower than 5, which is not suitable for spraying water paint;

4. Thickness requirements: single spraying should not be too thick (standard 20-35um), so as not to dry slowly or crack;

5. Construction viscosity: viscosity (4 cups) for 35-40 seconds, generally add no more than 20% water, the viscosity is too low and easy to sag, and the viscosity is too high to affect the gloss and easy to crack; The viscosity of silver powder paint should not be higher than 15 seconds, so as not to affect the whiteness of silver powder.

After adding water and stirring, it needs to stand for 3-5 minutes before spraying;

6. Two-component water paint Note: AB component is fully stirred, after standing for 30 minutes, add 10-15% clean water and stir evenly, filter and spray; AB group was used within 2 hours after mixing; The interval between two-component primer and topcoat spraying shall not be less than 2 hours; The same type of product can only be sprayed for the second time after the surface is dry;

Water-based industrial paint construction instructions.

1. It is strictly forbidden to contact with oily substances, stir evenly before use, and dilute with water appropriately according to actual needs, but generally add 0-10% of the water as the best.

2. Brushing, roller coating, spraying, dipping coating are acceptable, and the construction temperature is 5

3. Before construction, the surface oil, sand and debris, loose floating rust, and the thickness of the rust layer should not exceed 120 microns.

4. The storage temperature is 0, stored in a cool and dry place, anti-freeze and anti-sun, and the shelf life is 18 months.

In recent years, China's water-based coatings have become more and more popular in the market, and people's demand for improving their quality of life and health is also increasing. Traditional water-based industrial paints for architectural coatings and paints have become popular. At present, the technology of waterborne industrial paint is becoming more and more mature, and is gradually applied to the automotive industry, container spraying and machinery and other fields.

Water-based industrial paints have many advantages worth paying attention to:

1. The harmful gas emission of water-based industrial paint is very low, will not produce pollution, and is more environmentally friendly.

2. Strong adhesion, explosion-proof skin, anti-cracking, anti-shedding;

3. Water resistance and weather resistance, long-term protection.

4. It can be painted sensitively hidden, saving time and effort;

5. Anti-back sticking, anti-flash, saving more than 1 time compared with paint;

6. Waterborne industrial coating film is tough and impact-resistant;

7. Non-combustible and non-combustible to reduce storage and transportation costs;

8. Industrial water-based coatings are easy to construct and dry quickly;

What are the precautions for the construction of water-based industrial paint?

1.The water-based industrial paint should be evenly stirred before painting. If the viscosity is high, add the right amount of water. The amount of water should not exceed 10, and it should be stirred while adding water to ensure uniform paint flow;

2.Before applying water-based industrial paint, remove lime sand, welding slag, oil stains, floating rust and old patent leather from the surface of the workpiece;

3.For the second spray, wait until the first coat is dry, with an interval of at least 24 hours;

4.When using water-based industrial paints, it is forbidden to mix them with other paints and organic solvents to prevent the deterioration of paint components.

5.At the end of construction, the equipment used should be immediately rinsed with clean water to prevent the paint from drying on the equipment. The remaining paint should be stored in a sealed manner, and if the surface of the water-based industrial paint has developed a dry skin, it can be filtered with a 100-mesh screen before use.

6.After application, the paint film can be self-drying or dried at low temperatures. When drying, the leveling time at room temperature is not less than 15 minutes, the baking temperature is not less than 60, and the baking time is not less than 25 minutes;

7.It is recommended that water-based industrial paint be used in two bends; It can be applied by dipping, brushing, or spraying methods.

Water-based paint is a new type of environmentally friendly paint material, which has the characteristics of plump paint film, crystal clear, water resistance, aging resistance, fast drying, and easy to use. Therefore, many furniture and floors will choose water-based paint to decorate the surface. So how is water-based paint used, and what are the precautions for its use, see me for you one by one.

First, how to use.

1.Grassroots treatment.

a.First, the ash blocks, scum and other debris on the decoration surface should be shoveled and removed, and the oil stains on the surface should also be cleaned with cleaning agent.

b.After the surface is completed, the SG821 putty is adjusted to a suitable consistency with a dilution of water and vinyl acetate latex (ratio of 10:1), and the wall is filled with hemp surfaces, honeycombs, holes, and defects.

c.After the putty is dry, first smooth the excess putty with a knife, and then polish it with coarse sandpaper.

2.Medium coating application.

a.The paint should be fully stirred with a portable electric mixer before use, and the paint must be well blended.

b.When brushing the paint, it is necessary to pay attention to the technique, and the paint should be smoothed, and it generally needs to be dried for more than 4 hours before the next polishing process can be carried out.

c.Use fine sandpaper for sanding, the force should be light and even, and the coating should not be worn through, and the surface should be cleaned when grinding.

3.Surface coating.

The material, tooth period, alkalinity, and dryness of the base layer are different, so it is still necessary to test spray on the part of the wall to determine the compatibility of the base layer and the coating, and at the same time determine the appropriate coating amount.

2. Precautions for use.

1.Painting procedure: When applying floor paint, it is necessary to consider the impact on the wall emulsion paint. Paint the wall first, leave the last one, and then paint it after the floor paint is finished.

2.Floating dust cleaning: In the early stage of Shi Lu Kaiqing's work, a large area of repeated dust removal should be carried out to keep the surface of the wood neat and smooth.

3.Appropriate temperature: Know the indoor temperature when you start working. Try not to work in an environment below 5, otherwise it will prolong the paint drying time, and in addition, the water-based paint should not be directly exposed to sunlight.

4.Look at Sun Xin's humidity: if the humidity is greater than 80%, it is not suitable for construction, otherwise it is easy to have problems such as whitening of paint film.

When using water-based paint, it is necessary to understand the specific methods and matters. What are the precautions for water-based paint construction? PChouse will take you to find out.

1. Requirements for spraying tools, mixing containers, mixing tools, etc.

Do not mix with paint tools, spray guns for spraying paint require 2 times with thinner, 2 times with dish soap water, and 2 times with clean water before spraying water paint.

2. Water paint spraying has requirements for substrates.

The substrate treatment is consistent with the requirements of spraying paint and patting eggplant, shot blasting grade, no dust and no oil stain, if the substrate has oil stains, the oil stain needs to be cleaned; Spraying on the original paint surface requires brushing treatment;

3. Temperature and humidity requirements.

When the wet finger is greater than 75, the temperature is lower than 5, and it is not suitable for spraying water paint.

4. Thickness requirements.

Single spraying should not be too thick (standard 20-35um), so as not to dry slowly or crack.

5. Construction viscosity.

Viscosity (coating 4 cups) for 35-40 seconds is appropriate, generally add no more than 20% water, the viscosity is too low and easy to sag, and the viscosity is too high to affect the gloss and easy to crack; The viscosity of silver powder paint should not be higher than 15 seconds, so as not to affect the whiteness of silver powder. After adding water and stirring, it needs to stand for 3-5 minutes before spraying;

Paint is a more common decoration material in our home life, and we should be very clear about the construction method of paint. Water-based paint is a common type of paint among many paints, and many people may not know much about water-based paints, so it doesn't matter. Today, I will introduce to you how to use water-based paint?

What are the problems to be paid attention to in the construction of water-based paint?

How to use water-based paint?

1. Master the humidity: If the humidity is too much, more than 80%, it is not suitable for construction. Otherwise, there will be problems such as whitening of the paint film.

2. Clean up the floating dust: Be sure to clean the floating ash, be sure to remove the dust repeatedly in a large area, and then keep the surface of the wood neat and stable.

3. Suitable temperature: When the temperature drops below 5, the drying time of the paint will be prolonged, and it cannot be exposed to direct sunlight.

5. Wood quality construction: to understand the material of wood, if it is hard wood, it can be directly painted, if it is ordinary wood, it must be treated with transparent putty as the substrate before it can be painted.

6. Coating grasp: the paint should be thin but not thick, and it can be carried out in multiple channels with thin layers; When doing multi-layer coating construction, each painting should be carried out after the lower layer is dry, and each time it should be polished.

7. Timely construction. The two-component or three-piece paint must be stirred evenly after being proportionally blended, and then stand still for 15 minutes, so that the air bubbles caused by the stirring can be discharged before use, and if necessary, it should be filtered before use, and the paint must be used up within 4 hours after the paint ratio is good.

8. Pay attention to safety. The ratio of paint and matching, this chain is different with the specific product, and the construction personnel should read the product manual. In addition, paint is a flammable product, so pay attention to safety during construction.

What are the problems to be paid attention to in the construction of water-based paint?

1. After the floor is polished with a grinding machine, then polished with No. 400 water sandpaper, and the surface of the floor is wiped with a brush and a dust cloth to remove the floating dust.

2. Brush the primer with a wool pen or wool brush, brush the water-based primer 1 or 2 times, polish it flat and smooth with 800 water sandpaper after each drying, and wipe the surface of the floor with a dust cloth to remove the floating dust.

3. Putty caulking treatment is to scrape the board joints and floor wood holes with water-based wood putty to fill the board joints and floor wood holes, and the putty color is required to be the same or close to the floor. After drying, use No. 800 water sandpaper to smooth the fine sand, wipe the surface of the floor with a dust removal cloth to remove the floating dust; Then use the same putty to scrape a second time to ensure that the joints and wooden holes in the floor are filled and filled, and then the floating dust is removed with a dust removal cloth.

4. Brush the primer once with a water-based primer diluted with 5% 10% water per kilogram of primer or spray it again, and then smooth it with 1000 water sandpaper after drying, and then wipe the surface of the floor with a dust cloth to remove the floating dust.

The use of water-based paint is actually the same as the use of ordinary paint, so as long as you understand the construction method of paint, you can grasp the use of water-based paint faster, and I hope that the introduction can provide useful help to you.
