follow the small editor below to understand, brush latex paint common 8 problems and apply latex paint two ways!
01 coating is not smooth
the main reasons are: paint liquid has impurities, paint liquid thick, latex paint quality is poor.
solution: in the construction to use a good leveling brand, the last time before painting, paint liquid should be filtered and used

. The lacquer liquid can not be too thick, when the coating is not smooth, you can use fine sandpaper to polish smooth, and then paint again.
main reason for the
02 fall: the coating sticks too low and the coating is too thick.
solution: the construction must adjust the consistency of the paint, can not add too much water, the operation of the pen must be diligent, less slugs, diligent, to avoid the appearance of hanging, flowing. If a drop occurs, wait for the paint film to dry and polish with fine sandpaper, clean the finish and then paint it again.
03 blistering
main reasons: there is improper treatment of the grass, the coating is too thick, especially when the large core plate to do the grass is prone to foaming.
solution: the paint should be stirred well before use, master the consistency of the lacquer liquid, you can brush the glue on the bottom putty layer before painting. When reworking repair, clean the foaming peeling area, brush the glue before repairing.
04 shedding
the main reasons: latex paint construction temperature is low, failed to form a continuous coating film and cracking, water will fall off;
Solution: before the construction of the first observation, if there is leakage should be timely please the relevant departments to solve, should be added special treatment, it is recommended to use durable and waterproof bullet batch for the wall for pre-treatment, and then according to the conventional brushing, construction must be clean wall treatment.
05 discoloration and fading
the main reasons: some walls are too hot, long daylight time, or water-soluble salt crystallization on the surface of the wall, and cause latex paint discoloration and discoloration;
: Do not use both latex and polyurethane paint, you can apply latex paint after two days of paint, or wait for latex paint to dry thoroughly before brushing the oil.
06 crack
the main reasons: construction temperature is too low, can not reach the film temperature of latex paint can not form a continuous coating film;
: in the construction process to deal with the grass-roots, pay attention to the temperature, in accordance with the formal process of construction, the selection of cement putty and other materials quality assurance.
07 anti-alkali powder
the main reason: the grass-roots is not dry on the wet construction, unwashed solid primer and paint is also an important reason.
: if the anti-alkali powder is found, should be re-coated, the painted material removed, until the grass-roots drying and then construction. Construction must be first brushed with sealing primer, especially for the new wall, the consistency of the paint should be appropriate, the white wall should be slightly thicker.
08
main reasons: paint is too thin, not enough times or poor material quality.
solution: in the construction should choose a high solidity, strong cover of products, such as the discovery of the bottom, should increase the number of paint brushing, in order to meet the wall requirements of the painting standards.
there are two ways to apply latex paint: one is spraying and the other is brushing.
is the difference between the two? Comparison of merits!
way one: latex paint brush
need to be manual step-by-step operation, low efficiency and labor force. If it is a paint with faster dryness and poor leveling, it is easy to leave brush marks and uneven film thickness, which affects the flatness and rendering effect of the wall.
Advantages 1: Relatively than spray brush can save latex paint, brushing the wall is more textured
Advantage 2: Post-repair convenience
Disadvantages 1: serious powdering, brush marks, hair loss, uneven phenomenon

Long duration, corner clearance is more difficult to deal with
mode two: latex paint spraying
the principle of latex paint spraying is through a booster pump (generally a plunger pump), so that the coating supercharged high-pressure coating through the high-pressure tube to a special high-pressure gun, and from the special nozzle to release pressure and achieve the purpose of dispersing atomization, high-speed coating on the coating.
1: Excellent surface quality. Paint sprayed on the wall to form a smooth, dense coating, no brush marks
2: high coating efficiency. Single-person operation spray efficiency of up to 350-550 m2 / h, is 10-16 times the manual brushing
advantages 3: delay the life of the coating. The use of high-pressure spray atomization, so that the paint grain to obtain strong momentum deep into the wall face gap, so that the paint film and the wall form a mechanical bite, enhance coating adhesion

The color difference of repair will be more obvious than painting, so the protection work of the construction team will be relatively large
latex paint in the process of painting may appear a variety of quality problems, which need to be distinguished to solve, the above are the construction of several common latex paint brush quality defects and solutions, as well as latex paint construction methods.
