What is the difference between the construction process of inorganic coatings and ordinary coatings?

Inorganic paints are essentially different from conventional water-based paints (such as latex paints). Paints such as latex paints rely on water-based resin emulsions to form a film, just like a layer of chemical glue sticking to the wall, while inorganic paints are made from natural materials. Quartz is a series of silicates refined and smelted at high temperature, and through silicification reaction, it can penetrate 0.5-2mm of the wall to form a layer of silicate rock that is permanently and firmly integrated with the base.

Inorganic paint must be fully stirred before construction. Usually, it is best to use a hand mixer to stir slowly and evenly for 3-5 minutes. Try not to stir too much, so as not to affect the construction due to foaming. It will not automatically level like organic coatings, so after the coating is evenly spread during the construction process, the lines must be uniformly accepted to achieve the most perfect decorative effect. The unused paint must be sealed in time, and it can be stirred slowly again when it is used again. If it accidentally splashes into the eyes, rinse it with plenty of water in time.

1. The construction steps of inorganic coatings are roughly the same as those of organic water-based coatings

1. Wall base treatment: Scrape putty twice in batches, level the wall, grind it flat, no hollow, no dust (construction conditions should not be lower than 5 °C, and the humidity of the wall should not exceed 80%)

2. Brush the inorganic primer once, (slowly stir evenly for 2-3 minutes before using the primer) to cure the substrate to make the PH value of the wall consistent (theoretical value of the primer area is 10㎡/kg once)

3. After the primer is dry at room temperature for 2 hours, you can apply the inorganic paint for the first time without touching the wall with your hands or dust (slow stirring for 5 minutes before using the topcoat), and apply the first time The top coat is evenly distributed and the texture is uniform. (Because the inorganic coating is a mineral, unlike the latex paint, which is a layer of colloid, it will automatically level, so the inorganic coating must be evenly distributed and uniform to receive the texture), and the surface is dry for 2 hours. Afterwards, local repair and point brushing can be carried out.

4. It is generally recommended to apply the inorganic coating for the second time every other day for better effect. In theory, the inorganic coating can be applied for a second time without sticking to the hand and fading after it has dried on the surface for 2 hours at room temperature. what wax is used for paper coating

5. Partial repair and acceptance (the construction steps of the inner and outer walls of inorganic coatings are roughly the same, the theoretical construction area of ​​the inner wall is 4㎡/kg twice, and the theoretical construction area of ​​the outer wall is 3.5/kg twice).

2. Construction area of ​​inorganic coatings

(1) Roller coating

Inorganic primer is 20kg per barrel (20kg/barrel), 10㎡/kg for one coat, 1 barrel of 200㎡, ie 0.1kg/㎡ (primer can be brushed once).

Inorganic interior wall paint 25kg per barrel (25kg/barrel) is applied on both sides of 4m2/kg, and one barrel can be painted with 100m2, that is, 0.25kg/m2.

Inorganic exterior wall paint is 25kg per barrel (25kg/barrel), 3.5-4㎡/kg for two times, and 1 barrel can be painted 87.5-100㎡, that is, 0.25-0.28kg/㎡.

(2) Spraying

The inorganic primer is 20kg per barrel (20kg/barrel), sprayed once 8㎡/kg, 1 barrel of 160㎡ (the primer can be applied once).

Inorganic interior wall paint is 25kg per barrel (25kg/barrel) sprayed on both sides of 3㎡/kg, and 1 barrel can be sprayed with 75㎡.

3. Special attention

Inorganic mineral coatings, including primers, must not be diluted with water, let alone blended with any other organic coatings.

Do not apply directly to plaster lines and plastics. (If you need to paint the gypsum line, please use the inorganic coating specially for painting the gypsum line)
