The construction method of stone paint, the construction method and steps of real stone paint

Stone paint is real stone paint.

The construction method is as follows:

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 for using stone paint:

1. Scaffolding during construction.

It 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, xylene is used for tools.

and other solvents for cleaning.

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.

One. Stone paint construction method:

1. Before the construction of stone paint, the surface should be smooth, dry, free of oil and floating dust, etc., such as cracks, uneven and uneven places, repair and shovel.

2. It is recommended to use paint during construction, and the construction spray gun should use a special stone paint spray gun.

3. Before construction, the experimental spraying of the paint effect is to determine the pressure and the caliber of the spray gun, and also to see whether the viscosity of the paint is too large, and if the viscosity is too large, a small amount of water can be added to dilute it, so as to ensure that the spraying is uniform. The pressure, caliber and viscosity of the spray gun all affect the appearance of the coating.

4. It is necessary to wait until the stone paint paint is completely dry and dry before applying the overcoat, so as not to affect the overall construction effect and film-forming performance of the topcoat. Stone topcoat is also recommended for spray application.

5. Construction tools should be cleaned with water after use.

Two. Stone Paint Notes:

1. Stone paint should be placed in a dry place, with a storage temperature of 5 35, and heat sources, freezing, and exposure to the sun should be avoided.

2. The storage period of stone paint is one year, and it can also be used if the inspection is qualified after the storage period.

3. Wet weather should be avoided during the construction of stone paint, and outdoor construction cannot be carried out in rainy and windy weather. If the construction is carried out after rain, the exterior wall should be completely dried before construction.

4. Stone paint cannot add organic solvents and solvent-based coatings.

The construction methods and steps of real stone paint are as follows:1. Process flow: wall base construction, acceptance, original wall construction, elastic line, grid, sticky strip Brush closed primer, paste grid line, use special roller to implement brushing, spray real stone paint, brush topcoat, and local repair.

2. Grass-roots treatment: After the grass-roots acceptance is qualified, local repairs will be carried out. Requirements: flat, smooth, no oil stains, no cavities, no trachoma, smooth corners, straight.

3. Brush the closed primer: Brush the closed primer on the base layer, and require uniform brushing and no missing brushing.

4. Paste the grid line: In order to ensure the consistency of the brushing effect, it is good to use the adhesive strip to paste the dividing line.

5. Special spray gun for spraying: Requirements: Use a special spray gun to spray to ensure that the fancy is uniform, no knots, no continuous pieces. After spraying, it should be allowed to dry naturally 6 up and down, and the paint should be painted on the basis of surface dryness.

6. Brush topcoat: requirements: uniform, no missing brushing, and the color separation line should be clear, straight and straight.

7. Inspect the construction quality and repair other links after local pollution.

After 12 to 24 hours, polish.

Spray the bottom oil twice--- spray the real stone paint 2-3mm--- spray the surface oil twice 1, the real stone paint is required to be smooth, strong and no cracks.

2. First seal the bottom with an anti-alkali sealing primer or wall treatment agent, and then spray the real stone paint after drying, spray once or twice (you can also scrape), and the recoating interval is 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 construction effect, provide a comprehensive construction plan for real stone paint.

First, let's take a look at the tools used in spraying real stone paint.

The commonly used real stone paint spraying tool is the spray gun of real stone paint. For spray guns with real stone paint, the air pressure should be controlled at 4 to 7 kg per square centimeter when used. In addition, what we need to control is the construction temperature, it is recommended that the construction temperature should be kept above 10 degrees Celsius, below 35, which is the most reasonable construction temperature.

The second point is that we look at some requirements when spraying real stone paint.

First of all, we need to understand the thickness of real stone paint, for the thickness of real stone paint, I personally recommend that you control it at about 2mm to 3mm. When operating, the nozzle of the real stone paint spray gun is generally 400 to 800mm away from our wall, that is, the distance between the spraying surface and the spraying surface is the most reasonable.

The third point is the specific operation requirements of real stone paint.

When real stone paint is sprayed, I personally recommend that you spray it two to three times. Keep the interval between each pass about two hours. Polishing can be performed after 24 hours after drying.

If multiple spray guns are used for simultaneous spraying, when spraying the same wall, the same type of spray gun should be used, so that the floating point of each spray gun nozzle is basically the same, otherwise it may affect our overall aesthetic effect.

(1) The use of small particles of real stone paint, after spraying, the surface of the exterior wall is required to be smooth, small fluctuations, uniform particle distribution, dense, and consistent color.

2) All the yang corners during the construction of real stone paint, and the long side to the short side should be typeset.

(3) The grid tape should be paper tape, and the paper surface has a good adsorption effect on the real stone paint; If plastic surface tape is used, it will cause the real stone paint to run. At the same time, during summer construction, the tape is required to have good temperature resistance to avoid melting on the back of the tape at a slightly higher temperature.

4) The ash seam is required to be horizontal and vertical, and the width and narrowness are consistent; Special attention should be paid to not removing the primer when tearing off the lattice strip.

(5) Grasp the tearing time of the grid tape, the surface of the real stone paint is dry, and it can be torn off when pressed by hand without obvious indentation and without sticking to the hand. If you tear it off too early, it will cause the real stone paint to flow; If you tear off too late, first, the grid tape is not easy to tear off, which will cause the real stone paint at the ash seam to be removed, and the ash seam is not straight.

6) The same batch of real stone paint should be completed at one time to reduce the color difference of different batches of paint.

1. Before construction, the wall needs to be treated, and the wall is required to be relatively smooth, without any dust and stains, and relevant tools should be prepared, such as sandpaper, rollers, putty knives, putty scrapers, etc. 2. During the formal construction, the wall needs to be treated to ensure that the wall is smooth and firm, and then the putty must be scraped, and the putty after scraping is required to have no cracks and no concave and convex phenomena. 3. To apply the primer again, you need to paint the primer on the surface, and it must be evenly applied and cannot be missed.

4. Spray real stone paint, be sure to stir the real stone paint evenly, and then spray, the pressure should be adjusted correctly, generally sprayed in the order from top to bottom, from left to right, and it should be noted that there can be no leakage of spraying. 5. After spraying, you can wait until it is dry before you can polish it, and then spray the topcoat after it is dry.

The above is the answer to this question.

Questions. What effect does putty have?

Whitening and leveling effect.

Questions. Can the process of scraping putty be omitted?

If the putty is not messy, the primer is directly applied, and the adhesion degree is the same as the putty bonding effect?

Is the primer adhesion directly applied without scraping putty the same as the adhesive effect of scraping putty?

No, the effect of scraping putty is better.

If the wall is flat, is there no problem, the effect is the same?

Questions. When you say better, do you mean adhesion or flatness?

Adhesion. Questions.

The house has been in good shape for ten years, and the walls need to be treated.

If there is a peeling area, deal with it, then scrape the putty, and finally proceed.

1.First, the wall is treated, and the uneven wall is polished and repaired.

2.Scrape one or two layers of exterior wall waterproof putty.

3.After the putty layer is dry, polish the burrs and knife marks, and roll coat Yuema water-based alkali-resistant sealing primer.

4.After the primer is dry, divide the grid according to the design requirements (e.g. 6 24 or 5 20).

5.Paste the grid line.

6.Cut off unnecessary or overlapping tape with a knife.

7.Thin spray Yuema natural real stone paint again, completely cover the wall, the thickness is basically uniform, the color is uniform, and then the second spraying, the thickness is about 2-3.

8.Pull open the grid tape.

9.Polishing and trimming, correcting defects, and marking up areas where lines are contaminated.

10.Roller coating (spraying is also acceptable) Yuema water-based transparent weather-resistant cover glossy coat.

Base surface treatment. 1. One-to-three cement slurry painting and health care for more than 15 days, the powder surface should be flat but not too smooth, and the cutting angle should not be too sharp;

2. Before construction, there shall be no moss, grease or other pollutants on the surface of the coated object, and if there is, it must be completely removed, otherwise it will affect the adhesion and keep it fully dry.

3. The base surface coated with the old paint must be tested or confirmed to be adhesion construction, otherwise the old paint must be removed.

Roller coating alkali resistant sealing primer.

Evenly spray and roll a layer of moisture-proof and alkali-resistant sealing primer on the base layer, completely enclose the base surface and really play the role of anti-seepage, moisture-proof and alkali-resistant. The special primer for real stone paint is close to the color of real stone paint, which can prevent real stone paint from penetrating the bottom and causing flowering.

Paste the masking paper into grids (this step can be ignored if the finish is not gridded).

First use a ruler or marking line to make a straight line mark, then use black paint to draw the line, and then paste the masking paper grid, paste the masking paper should pay attention to the horizontal line must be pasted first, and then the vertical line, sealed with the joint, can be nailed with iron nails, so as not to find the source of the tape after spraying.

Spray real stone paint.

Before spraying the real stone paint, the real stone paint should be stirred evenly, installed in a special spray gun, and ready to be sprayed. The order should be sprayed from top to bottom, from left to right, and no spraying should be missed. You can quickly spray a thin layer first, and then spray slowly, smoothly and evenly, with a thickness of 2-3mm.

The effect of spraying is related to the size of the nozzle and the distance from the nozzle to the wall. When the diameter of the nozzle is 6-8mm, and the distance between the nozzle and the wall is appropriately increased, the spots sprayed are larger, and the convex and concave feeling is stronger; When the diameter of the nozzle is 3-6mm, and the distance between the nozzle and the wall is appropriately adjusted, the spots sprayed are smaller, and the finish is relatively flat.

Remove the masking paper.

The masking paper should be torn off immediately after the real stone paint is sprayed, and the masking paper must be removed carefully, and the corners of the coating film must not be affected.

The cover is coated with a topcoat. After the real stone paint is completely dry, it can be fully sprayed with roller coating glossy paint, pay attention to the construction temperature is not less than 10, spray twice, 2h interval, the topcoat is milky white before drying, and transparent color after drying.

First, the construction method of the main material of real stone paint (stone particle layer) is spraying. The tools are air pumps and spray guns. Primers and topcoats can be sprayed or roller applied.

Second, the construction process.

1.Clean the base surface: deal with the concave and convex, uneven, edged and angular positions of the base layer, and clean up the floating ash.

2.Scrape putty: According to the flatness of the base surface, scrape the special waterproof putty once or twice. The flatness control error value is less than 4mm.

3.Primer: Use a roller or spray gun to evenly coat the primer, the purpose is to waterproof the alkali and color the lattice seam.

4.Lattice sewing paper: according to the design requirements of the grid method, measuring, marking, sticking, the lattice part with masking paper.

5.Use a spray gun to spray the main material of real stone paint, and adjust the air output of the spray gun according to the size of the pattern and the strength of the undulation according to the design requirements. The number of sprays is also adjusted according to the color, and the spraying is 1-3 times.

6.Remove the masking paper.

7.Paint transparent topcoat: Roller or spray transparent protective topcoat 1-2 times to improve the self-cleaning performance of real stone paint.

8.End cleanup, done.

Note: 1The primer is the color of the lattice seam and is weather-resistant.

2.The construction of each process needs to be carried out after the previous process is dried sideways. The drying time of each brand product varies slightly.

The construction process steps of real stone paint are the same as many exterior wall coatings, batch putty leveling, primer, grid line, spraying real stone paint, tearing tape, brushing topcoat, of course, this is just a simple step, each step has a lot of precautions, construction this kind of thing or practice makes perfect, from practice to exercise.
