How to make real stone paint for exterior walls, construction methods for real stone paint for exter

Construction method. 1. Real stone paint is required to be smooth, firm and no cracks.

2. First seal the bottom with an anti-alkali sealing primer or wall treatment agent, and then apply real stone paint with a special spray gun after drying, spray once or twice (you can also scrape), and recoat the interval for more than 2 hours.

After a few hours, apply the water-based primer cover varnish again.

4. Primer and topcoat must be applied to ensure construction quality and durability.

5. For the complex base layer, in order to ensure the best construction effect, a comprehensive construction plan for real stone paint is provided.

Precautions. 1. During construction, the scaffold should be about 30cm away from the wall, if the distance is too close, there may be joints in the spraying part between the upper and lower scaffolding, which will affect the decorative effect.

2. Do not spray parts and objects, and should be separated by baffles or paper.

3. The temperature should be higher than 5 during construction, and the wind force should not be suitable for construction when the wind is greater than level 4. Rain and snow should be avoided within 24 hours of spraying the main coating.

4. Oil-based primer and overcoat are flammable dangerous goods, and fireworks should be strictly prohibited during construction.

5. After the construction of the main coating, the tool should be cleaned with water immediately.

6. After the construction of oil-based primer and overcoat is completed, the tool is cleaned with xylene and other solvents.

7. During the construction process, it is strictly forbidden to add water to dilute the materials at will.

8. When the temperature is low, the same wall must survive at one time, otherwise there will be a slight color difference problem even if the same batch is constructed for a long time.

In modern buildings, real stone paint is often used for exterior walls, which is a water-resistant, alkali-resistant, and water-based environmentally friendly paint with strong adhesion made by a special process, which has the decorative effect of granite, marble and other stones, giving people a solemn, elegant and luxurious visual enjoyment. It is suitable for villas, apartments, buildings and other buildings, so how to make real stone paint for exterior walls? The following is an introduction to the practice of real stone paint for exterior walls.

1. Base surface treatment.

Before the construction of real stone paint, it is necessary to do a certain treatment on the base surface of the exterior wall, first of all, remove the loose base, peeling, hollowing, chalking and other conditions. Putty is used to repair potholes to make the base layer smoother. Because the real stone paint itself has a certain thickness, the flatness of the base surface does not need to be as high as that of a thin flat coat.

2. Paint the sealing primer.

Wait for the putty to dry through, and apply the sealing primer again. When applying the sealing primer, there is no need to add additional thinner, the main purpose is to clean the base layer, and the roller coating construction mode is adopted, or the spraying construction mode can also be used.

3. Spray solid color primer.

Spraying primer can make the color of the substrate consistent, avoid the phenomenon of blooming caused by the real stone paint coating film, make the color look more uniform, and have a better decorative effect. It is recommended to choose a thin-coated latex paint for external use with good water resistance. Try to make the color of the paint close to the natural color of the real stone paint.

When painting the primer, we must pay attention to uniformity, there can be no leakage, through the bottom of the situation, the primer should be painted twice, can achieve the decorative effect of imitation stone. First, the real stone paint is sprayed in a grid, and then the base layer is painted on the grid, and when a large area is sprayed to cover the cherry blossoms, the grid should be scraped.

Fourth, spray real stone paint.

First spray a slightly thinner coating, wait until the paint is more uniform, thoroughly dry and start spraying a second time, when spraying, the macro draft coating is recommended to be thicker, with the spray of air to blow the sprayed finish, so that the pattern is closer to the stone effect. If you want to achieve the decorative effect of marble, it is recommended to use a double-nozzle spray bucket to achieve the decorative effect of overlapping colors. It is necessary to keep the coating film thin and uniform.

5. Spray overlay varnish.

In order to protect the finish of the real stone paint, have a better gloss and pollution resistance, it is necessary to carry out overlay treatment, and then spray the overlay varnish after the real stone paint is completely dry. It is necessary to pay attention to keeping the viscosity, air pressure and other sizes consistent, and to prevent sagging.

Steps to make real stone paint for exterior walls:

Basal inspection. Carefully inspect the base surface before construction, and the plastering layer needs to be dried for at least 4 weeks, with a moisture content of less than 10% and a pH value of less than 10. The base surface should have sufficient strength, should be flat and solid, no hollowing, no cracking.

Batch scraping putty. After the base surface is inspected, the construction surface is scraped and leveled with high-quality exterior wall putty until the flatness meets the requirements. After the putty is scraped and polished, it is sprayed with clean water for curing, and the primer is applied after the curing is completed and dried for 1 3 days (under standard conditions).

Apply primer. The wool roller is used to evenly coat the alkali-resistant sealing primer of Guangtian exterior wall 1 2 times in the way of first corner and then large surface, and the consumption is about. After the sealing primer is completed, it needs to be dried for 2 to 3 hours (under standard conditions) before the real stone paint is applied.

Spray real stone paint. Use a real stone paint spray gun to spray natural real stone paint, generally no need to add water to dilute, if you need to add water, no more than 3%, and stir well. In order to ensure the effect, it is recommended to use two spraying applications, first spraying evenly and thinly on the wall surface where the primer is coated, and spraying the second coat after spraying and drying for 2 4 hours (under standard conditions).

According to the specific texture effect, the unit consumption of real stone paint is dried for 1 2 days (under standard conditions) after the spraying of real stone paint, and then the construction of overlay varnish is carried out.

Apply the overlay varnish. The use of spray guns or wool rollers for the construction of Guangtian water-based overlay varnish requires uniform coating and consistent gloss, and the overlay varnish is generally constructed 1 2 times, and the unit consumption is about.

1.Base treatment: clean the wall, remove loose objects, oil, dust, etc., to ensure that the wall is dry, flat and firm.

2.Primer brushing: Use real stone paint primer, dilute it according to the requirements of the manual, and evenly apply it to the wall with a brush or roller to ensure that the primer is evenly brushed and dried before the next step of construction.

3.Stone texture painting: use real stone paint, dilute according to the requirements of the manual, evenly paint the wall with a brush or roller, pay attention to the direction of the stone texture to paint, to ensure that the painting is uniform and the thickness is consistent.

4.Stone texture polishing: When the real stone paint is not dry, use a stone texture knife or other tools to polish according to the direction of the stone texture, so that the wall presents the texture and texture of the stone.

5.Topcoat brushing: Use real stone paint topcoat, dilute it according to the requirements of the manual, and evenly paint it on the wall with a brush or roller to ensure that the painting is uniform and the thickness is consistent.

6.Topcoat polishing: After the real stone paint is dry, use a stone texture knife or other tools to polish it in the direction of the stone texture, so that the wall presents a more natural and pure stone texture.

7.Waterproof treatment: After the real stone paint is dry, waterproof treatment is carried out to ensure that the wall is waterproof, moisture-proof and mildew-proof.

8.Fine trimming: After the construction is completed, the wall is finely trimmed to remove debris and stains on the wall to ensure that the wall is clean and tidy.
