Engineering paint is a kind of paint specially used in the field of engineering, but also a kind of paint, but many people don't know much about engineering paint, so what is engineering paint.

What is engineering paint

Engineering paint is a latex paint often used in construction projects. It is one of the exterior wall coatings and is mainly composed of titanium dioxide, styrene emulsion, talcum powder and other additives. The weatherability of the project is very good, and the protection time without refrigeration is at least three years. In addition, the painting area of engineering paint is very large, and there are not too many requirements for painting, so the construction is very simple. In addition, the paint film of engineering paint is very tough, good adhesion and strong hiding power, which is very suitable for use as paint coating for engineering exterior walls.

Project Paint Use

1, Primary Treatment: Before construction, clean the wall surface, clean the dust on the surface of the wall surface, etc. If there are stubborn stains, clean them with special cleaning agent. Then use putty to repair the incomplete part of the wall to ensure that the whole wall is flat, and then use a shovel to remove the excess putty when the putty is dry, and then use sandpaper to smooth it.

2, full putty on both sides: putty should be scraped before painting the engineering paint. The putty should be flat, smooth and even for the first time, and should be as thin as possible. Then the putty for the second time is the same as that for the first time, except that the direction of painting and scraping should be perpendicular to the direction of the first time.

3, fully mixed: after completing the second step, the engineering paint can be painted. previously, the paint must be mixed evenly. during spraying, the paint must be kept perpendicular to the decoration table, pushed forward in z-shape, and crossed horizontally and vertically.

4, spraying primer: the engineering paint must be applied on a dry, firm and clean wall surface, and attention should be paid to keeping the coating uniform when applying.

5. Repair: Pay attention to repair the unevenness of the wall surface when painting the first engineering paint. After painting, it will take at least 4 hours or more to proceed to the next step until it is completely dry. After the second brush does not require polishing process.

6, follow-up cleaning work: it is inevitable that the paint will splash during the painting process of the project. when all the walls are painted, the walls should be cleaned once to ensure the cleanliness and tidiness of the whole wall.

and how to use engineering paint are introduced to you. Engineering paint is also a kind of paint, but it is mainly used for exterior wall construction, so you must understand it clearly when using it.
