    How to spray water-based paint - base treatment.

    First, remove the ash blocks, scum and other debris on the decoration surface with a knife, if there is oil stains on the surface, wash them with cleaning agent and water, and then use a palm brush to clean the surface dust after drying. After the surface is cleaned, the SG821 putty is adjusted to a suitable consistency with a dilution of water and vinyl acetate latex (with a mix ratio of 10:1), and the wall matte, honeycomb, holes, and defects are filled.

    After the putty is dry, first use a knife to smooth the excess putty, and then polish it with coarse sandpaper;

    How to spray water-based paint - middle coating construction.

    The paint should be fully stirred with a portable electric mixer gun before use. If the consistency is large, it can be diluted with water, but the amount of water added each time should be consistent, and the consistency should not be different. The paint is then poured into a tray and coated with a paint roller for the first time.

    The rollers should be painted transversely, and then rolled longitudinally, driving the paint away and flattening. The rolling coating sequence is generally from top to bottom, from left to right, first far and then near, first the corners and corners, small surfaces and then large surfaces. The thickness is required to be uniform to prevent excessive coating from falling.

    The roller can not be applied to the corner of the shade, and it needs to be supplemented with a brush, and the coating should not be missed. Always remove the roller hairs that stick to the wall. Avoid overlapping brushstrokes, and wipe the paint stained to other parts with water in time.

    After the first middle layer coating is applied, it generally needs to be dried for more than 4 hours before the next polishing process can be carried out. Then, use fine sandpaper for sanding, the force should be light and even, and do not grind through the coating, and the surface will be cleaned.

    How to spray water-based paint - surface coating.

    Due to the different materials, tooth periods, alkalinity and dryness of the base layer, test spraying should be carried out on the local wall in advance to determine the compatibility of the base layer and the coating, and at the same time determine the appropriate coating amount; Before use, shake the container fully to mix it well, then open the container and stir it fully with a wooden stick; When spraying, the mouth should always be perpendicular to the decorative table (especially in the dark corner), and the distance is about to be adjusted according to the size of the decoration surface), and the nozzle pressure is the spray gun in a Z-shaped shape, and the horizontal and longitudinal crossing.

    Hello 1. Use clean water to adjust the paint to the appropriate viscosity for spraying, and measure it with a Tu-4 viscometer, and the appropriate viscosity is generally 20-30 seconds. If there is no viscometer for a while, you can use the visual method: use a rod (iron rod or wooden rod) to stir the paint evenly and then pick it up to a height of 20 cm to stop and observe, if the paint liquid is not interrupted in a short time (a few seconds), it is too thick; If the line is broken as soon as it leaves the upper edge of the barrel, it is too thin; When it is just stopped at a height of 20 cm, the paint liquid will form a straight line, and the flow will be cut off in an instant and become a drop down, which is a more suitable viscosity.

    2. The air pressure should be controlled in megapascals (3-4 kgf square centimeters). If the pressure is too small, the paint liquid atomization is poor, and the surface will form pitting; Excessive pressure is easy to sag, and the paint mist is too large, which not only wastes material but also affects the health of the operator.

    3. The distance between the nozzle and the object surface is generally 300-400 mm. Too close and easy to sag; If the paint mist is too far away, it is easy to have pitting, and the nozzle is far away from the object surface, and the paint mist is scattered on the way, resulting in waste. The distance of spraying distance should be appropriately adjusted according to the type of coating, viscosity and air pressure.

    The spraying distance of slow-drying paint can be farther, and the spraying distance of fast-drying paint is closer; When the viscosity is thick, it can be closer, and when the viscosity is thin, it can be farther away; When the air pressure is high, the distance can be a little farther, and the pressure can be a little closer; The so-called closer and farther is a small range of adjustment between 10 mm and 50 mm, beyond which it is difficult to obtain the ideal paint film.

    4. The spray gun can be moved up and down, left and right, and it is best to operate evenly at a speed of 10-12 meters, and the nozzle should be sprayed directly on the surface of the object to minimize oblique spraying. When spraying to both ends of the surface, the hand that pulls the trigger of the spray gun should be quickly loosened to reduce the paint mist, because the two ends of the surface often have to be sprayed more than twice, which is the place that is most likely to cause sagging.
