The surface layer of latex paint should be applied 2 to 3 times, preferably with an interval of 24 hours between each coat. Correct application of latex paint will not crack.

Causes of cracks:

1. The construction temperature is too low, and the film-forming temperature of latex paint cannot be formed to form a continuous coating film.

2. Improper treatment of the base layer, such as cracking of the coating film caused by cracking of the wall.

3. If the first coating is too thick and not completely dry, the second coating will be painted, which will cause cracking of the coating film due to the different drying speeds inside and outside.

4. The cracking of the cement putty scraped in batches causes the cracking of the coating film.

5. Bought a fake latex paint, fakes are generally manifested as bubbles on the wall, the color of latex paint can not cover the background color of the wall, and the paint surface cracks and peels after drying.

The latex paint in the room is generally brushed more than twice.

This usually needs to be painted twice.

1. Latex paint.

It can be sprayed 2 3 times, or it can be sprayed 4 times. If it is summer, it generally takes 1 to 2 hours, and in autumn and winter, it takes more than 4 hours. 2. Most of the latex paint used in the home construction is sprayed twice, if it is a decoration company.

For wall construction and spraying, latex paint is generally applied three times or more.

Spraying latex paint steps:

1. It is necessary to treat the part of the wool wall, because the flatness of the wool wall may not be particularly reasonable before spraying, including a lot of particles may still be attached to the wall, and they need to be cleaned up to keep the wall flat and facilitate the subsequent spraying construction.

2. Brush the interface agent on the flat wall.

This interface agent can also be called wall solidification.

Its main function is to ensure that the basic wall and the latex paint painted in the later stage form a better combination.

3. Brush the latex paint for the first time, and then brush the second time after the first latex paint is dry. The interval may be half a day or a day, depending on the temperature.

4. Polishing, because the second latex paint has been brushed, it is necessary to polish the surface to ensure that there is a certain adhesion effect, so as to facilitate the brushing of the topcoat.

5. Start to brush the topcoat part of the latex paint, and keep the large area of whitewash flat.

6. After all the above-mentioned construction is completed, the surface is maintained and protected.

Generally, wall latex paint needs to be brushed 2 or 3 times, which takes 3-4 days. The first coat is a primer, and the second and third coats are topcoats. Each layer of latex paint must wait until the last layer of paint has dried before proceeding.

Stir evenly before brushing latex paint, dilute it with an appropriate amount of water to avoid the first time the latex paint cannot be brushed.

On a sunny day, it takes two hours for the latex paint to dry. Generally, apply twice a day, once in the morning and once in the afternoon. Because each latex paint needs to wait until it is completely dry before it can be constructed, and it is also easily affected by temperature, climate, and the number of workers, so the construction period is relatively long.

What should I pay attention to when painting latex paint?

1.Before painting latex paint, be sure to treat the wall foundation well. If the wall foundation is not done well, it will affect the construction quality of latex paint.

Generally speaking, the dust and dirt on the wall foundation should be cleaned first. If there is an unevenness, remove the protruding part and trim the concave part.

2.If the wall is weathered or peeled off, the surface material needs to be removed and repaired with material. The purpose of this is to strengthen the adhesion of the latex paint to the wall, and the focus is to make the latex paint decorate better.

3.Before applying, control the dosage. When preparing latex paint, the actual amount of latex paint should be calculated according to the wall area, and some losses should be considered. If the amount of latex paint is not enough, it needs to be adjusted later, and the color difference may occur, which will reduce the effect of wall decoration.

Note (It is best not to paint the interior wall latex paint more than 4 times, for fear that the paint film is too thick, and the humidity of the room is too low, resulting in cracks in the paint film).

2. Exterior wall: clean the base layer of the exterior wall, and then mix it with double fly powder and cooked rubber powder to make a base. Then there is the latex paint, and the surface layer needs to be applied 2 to 3 times.

2. When is the best time to brush.

1. Latex paint requires that the construction environment temperature is not lower than 5, and the relative humidity is not higher than 85%, therefore, in the rainy season, Huangmei day, and the winter when the temperature is lower than 5, it is not suitable to brush latex paint. It is best to brush latex paint in sunny and dry weather.

3. How to brush latex paint.

1. Brushing: the advantages are strong flexibility, simple construction and saving paint; The disadvantage is that the efficiency is low, and it is easy to produce defects such as brush marks, sagging, and uneven brushing.

2. Roller coating: the advantage is high construction efficiency; The disadvantage is that it is prone to roll marks and the visual effect is average.

3. Spraying: The advantages are fast spraying speed, uniform coating thickness, smooth and delicate feel. 、***；The disadvantage is that it is easy to pollute the environment and it is easy to waste materials.

Generally, wall latex paint needs to be brushed 2 or 3 times.

The following points should be paid attention to when brushing latex paint:

1. The general rule of painting is from left to right, from top to bottom, first inside and then outside, first difficult and then easy.

Classification: 1. General-purpose latex paint.

The general-purpose latex paint is suitable for different consumer levels, is currently the largest market share of a product, the most common is matte latex paint, the effect is white and no luster, brush to ensure that the wall is clean and tidy, with a certain resistance to brushing, with good coverage.

2. Anti-fouling latex paint.

Anti-stain latex paint is a latex paint with a certain anti-staining function, which can wipe off some water-soluble stains, such as water-based pen prints, handprints, pencil marks, etc. However, for chemical substances such as chemical ink, etc., it cannot be wiped off, but the stain resistance is better, and it has a certain anti-fouling effect, not absolute anti-fouling.

3. Antibacterial latex paint.

People's pursuit of a healthy and clean ecological living environment is becoming more and more intense, and more and more attention is paid to products with antibacterial function. At present, the ideal antibacterial materials are inorganic antibacterial agents, including metal ionic inorganic antibacterial agents and oxide antibacterial agents, which have killing and inhibiting effects on common microorganisms, Staphylococcus aureus, Escherichia coli, Candida albicans, yeasts, molds, etc.

Primer: a layer of special primer; Topcoat: 2-3 coats of wall paint.

Base surface requirements and base surface treatment:

The substrate needs to be professionally treated, should have load-bearing capacity, and be firm and dry; Clean and dust-free, flat. The loose and peeling parts should be removed and repaired in time. Smooth and dense substrates with weak water absorption are not primed.

For other detailed requirements, please refer to the Code for Construction and Acceptance of Building Decoration Engineering JGJ73-91 or local codes.

For the base layer that does not meet the coating requirements, it needs to be professionally treated

Damaged, cracked, uneven and other parts of the wall should be repaired and smoothed with low-alkaline putty before priming.

The new concrete and cement mortar, mixed mortar plastering substrate needs to go through a 2-3 week ventilation and drying maintenance period, so that the water content of the base layer < 10% and the pH value < 10 before painting.

For lightly chalked and firm old coatings, a matching primer is sufficient. Old coatings that are heavily chalking should be thoroughly washed beforehand, and old oil-based paints should be completely removed.

For the old coating with no bearing capacity, crispy and flaky, it should be thoroughly removed and washed together with putty, and then leveled with putty after drying.

Latex paint uses.

polyvinyl acetate emulsion paint for interior walls; All-acrylic latex paint can be used for interior and exterior walls; Acetacrylic latex paint and latex paint with vinyl acetate and acrylic vinegar copolymer emulsion as the base material, as well as styrene acrylic latex paint** are cheaper than full acrylic latex paint and are used for exterior walls; These latex paints can also be made into high-build types (such as relief paints, real stone paints, etc.), and can be mixed with more fillers to treat uneven exterior walls.

All acrylic latex paint and styrene acrylic latex paint can be made into anti-rust primer for metal latex by adding anti-rust filler, which can be used as a primer on steel that has undergone degreasing and rusting; Latex paint has excellent adhesion to galvanized steel sheets, and is one of the most suitable coatings for galvanized steel sheets that have not undergone conversion treatment.
