Knowing the steps of exterior painting not only helps us to paint the exterior wall in order, but also allows us to have a better preparation for what we need to paint the exterior wall.

Steps: Dust and other build-up on the surface of the base layer are eliminated first. Relatively large dents are smoothed out with a polymer mixed mortar.

And wait for it to be dry, and the smaller holes and gaps are repaired with concrete natural latex putty. When the wall is returned to alkali and frost, it should be cleaned with an aqueous solution of sodium dihydrogen phosphate or an aqueous solution of dilute sulfuric acid, and the oil stains should be cleaned with detergent, and finally cleaned with water. The original coating of the base layer should be different depending on the situation:

Loose, crusting, brittle old coatings should be removed; Adhere to the old coating with strong sandpaper; Moisture-resistant coatings should be removed in full.

Brush primer (except for wood and paint surface), if the wall is loose and strong, you can put a roller on the base layer at the end of the removal and evenly paint one to two times of super glue (styrene acrylic emulsion or water-soluble engineering building super glue plus 3 5 times water dilution), can not be missed, nor can be painted too much to cause flow or deposition. Part of the putty, after the base layer is dry, use putty to level the uneven places, and smooth the sanding after drying. The finished putty should be stirred before application, and cold water can be added to adjust the putty when it is thicker.

Scrape the putty, place the putty on the backing plate, and brush it with a scraper or a leather scraper. According to the condition of the base layer and the decoration regulations, brush 2 or 3 times of putty, and each putty should not be too thick. The putty should be polished immediately with an abrasive cloth when it is dry, not wave-like, nor can it leave scratches, and the dust should be brushed off after the grinding and polishing is completed.

Precautions for painting exterior walls: Before the construction of the interior wall paint painting project, it is necessary to carry out certain maintenance of the exterior wall bricks, that is, to scrape the putty two or three times first, and make the wall as smooth as possible, without too prominent pits and protrusions, and there are no defects such as gaps.

First of all, the exterior wall brick is brushed with primer, the function of the primer is very critical, the morning light gel pen primer has a strong bonding ability, the wall alkali is closed, so that the interior wall paint can be bonded very firmly; It can also make the dust and putty bottom integrated, which greatly improves the moisture-proof characteristics of the wall; And it can save architectural coatings, so that the paint is more evenly painted, and the final effect will be very good.

In the construction of interior wall paint painting project, it is best to apply short wool wool rollers, and the painting should be timely to prevent loss of light and leakage. The painting of the paint is carried out only after this is done, but before here, it is necessary to check whether the primer is missing, whether the upper side is polluted by the environment, and only after this kind of construction is carried out can the construction of the first paint be carried out, and the painting of the paint also needs to ensure that it is symmetrical and consistent.
