Real stone paint base treatment, what is the cleaning of real stone paint primer?

Real stone paint construction process.

First, the base surface treatment:

1 1. Clean the base surface: remove the floating ash, cement and oil and other attachments on the construction surface.

1 2. Sanding the convex part that seriously affects the flatness, and meet the flatness requirements: (3mm).

1 3. Fill the obvious depression or hole with coarse putty, and grind it to meet the flatness requirements (3mm) after drying

1 4. Construction requirements:

1 4 1. The base surface is clean and tidy, hard and firm, and there is no debris attached.

11 2. The flatness meets the requirements (2mm).

Second, the rough layer construction:

2 1. Construction ratio: powder: glue: clean water = 10:1: When using, mix the cleaning water with 1 part of glue evenly, and then mix AW-55, use a hand drill to operate, add AW-55 while stirring, until the mixture is even.

2 2. The prepared putty should be placed for up to 4 hours, and it cannot be used for more than 4 hours, and the solidified slurry cannot be used.

2 3, a full batch of putty; When the greasy layer turns white, sand the greasy layer to remove the marks;

2 4. The greasy layer needs to be cured with water 3 4 times to make it more completely cured.

2 5: Construction Requirements:

2 4 1, flatness meets the requirements ( ;

2 4 2, the greasy layer has no obvious marks, and the surface is smooth;

2 4 3. The adhesion is qualified, and there is no powder loss phenomenon when picked with nails.

3. Closed primer construction:

3 1. Dilution ratio: direct construction, no dilution required;

3 2. Construction method: drum;

3 3. Construction requirements:

3 3 1, roll coating;

3 3 2, the construction is uniform, no leakage, and the dosage is reached;

Fourth, real stone paint aggregate construction:

4 1. Construction method: spraying with a spray point spray gun.

4 2. The number of construction times: two times: the first time plays the role of covering the bottom; The second pass requires the same effect as the board, and the interval between the two passes is 2 4 hours;

4 3. Construction requirements:

4 3 1, uniform, no bottom;

4 3 2, to achieve the required effect;

Fifth, the construction of varnish:

5 1. Construction method: spraying;

5 2. Number of construction times: one time;

5 3. Construction requirements:

5 3 1, uniform construction, no leakage;

5 3 2, to achieve the required gloss and dosage.

6. If you need to do lattice joints, you need to carry out the construction of real stone paint aggregates; The black seam is made of water-based black oil.

One-to-three cement powder scrapes the wall, primer sealing, lofting marking, pasting line marking, spraying real stone paint, removing line tape, spraying oil covering.

What to clean with real stone paint primer depends on the specific paint brand and model, and the common cleaning methods are as follows:

Water cleaning: For some water-based real stone paint primers, clean water can be used to clean. Pour clean water into the cleaning bucket, then use a brush or sponge to dip an appropriate amount of water and wipe the surface of the paint.

Organic solvent cleaning: For some oil-based stone paint primers, organic solvents such as alcohols and ketones can be used for cleaning. First of all, you need to pour the organic solvent into the cleaning bucket, and then use a brush or sponge to dip the appropriate amount of organic solvent and wipe the surface of the paint.

Baking soda cleaning: Baking soda is a weakly acidic cleaning agent, and it can also be cleaned for some real stone paint primers. Add an appropriate amount of baking soda powder to the water, stir the wisdom to sleep evenly, pour the cleaning solution into the cleaning bucket, and then use a brush or sponge to dip the appropriate amount of cleaning solution and wipe the surface of the paint.

It should be noted that when cleaning the surface of the paint, it is necessary to use a brush or sponge gently to avoid scratching or damaging the coating. After cleaning, it is also necessary to carefully check whether the coating has cracks, blistering, peeling, etc., and carry out necessary repairs and treatments.

First, the real stone paint construction plan: base surface treatment.

1) Remove the floating ash, remove the sand, warping and other parts.

2) For the mortar, debris and obvious sharp edges and bulges that adhere to the wall, they should be removed first.

3) For the oily parts, the original coating should be removed first, and the detergent should be thoroughly cleaned if it cannot be removed.

4) For the base layer of salt precipitation and alkali return, it can be cleaned with cleaning solution first, and then cleaned with water, or wire brushes, scrapers, and grass brushes can be used to remove the powder.

5) The loose, peeling and other parts of the base must also be removed and then repaired; For the leaking steel bars and iron parts, they should be smoothed and rusted removed, and anti-rust treatment should be done before brushing the coating;

6) If there is mildew on the wall, remove all the mildew with a solution formed by mixing three parts water with one part household bleach, apply it to the surface with mildew, wait for 20 minutes, and then add an appropriate amount of solution when it dries; Pay attention to wear protective glasses and protective devices; and rinse thoroughly.

7) For wall cracks, scrape and widen all cracks; Brush off the dirt that remains in it, and then fill it with 100% pure propylene or silica propylene putty; If necessary, fill again after a few hours; The walls must be painted completely and continuously;

8) If there is weathering, please remove it with a wire brush; Try to find moisture** that may cause weathering behind the cement and remove it.

9) Wipe off dirt, powder, retained paint particles, unbonded mortar, treated mildew, etc. with a solution made of water and laundry detergent, and rinse thoroughly, taking care not to let moisture enter cracks or porous areas.

Second, the real stone paint construction plan: old tile wall treatment.

After the base treatment, check whether the wall repair part, mortar moisture content and alkalinity are the same as the large area, if the difference is large, it will cause the surface coating color to be uneven. If so, it should be dealt with in a timely manner. Other areas should be inspected for missing surface defects.

The old wall needs to be renovated with a base layer, the surface moisture content is generally low, coupled with the corrosive effect of the atmosphere, the surface firmness is poor, and the water absorption rate is large, so it is necessary to apply a transparent primer or a closed primer. If the existing coating is well preserved, applying a primer is beneficial but not necessary. If there are any signs of weathering (which should be removed first) or if there is any loose coating (removed with a wire brush) and if the screed area is repaired, a primer should be applied.

For the old wall is an oil-based coating, it is recommended to use the tile renovation interface agent as a primer, and the method of use is to dilute the tile renovation interface agent with appropriate water, stir evenly and roll coating. If you have high requirements for the smooth and clean surface of the brush, wait for the primer to dry and gently polish, pay attention not to use force to polish, and do not damage the surface primer film. Roll once or twice depending on the actual situation.

For the old wall is a water-based coating, use an alkali-resistant sealing primer, and roll it can be applied once.

1. Treat the base surface to ensure that the base is clean and flat, and there is no chalking, sanding and other phenomena. 2. Scrape the anti-alkali sealing primer, which is best to scrape twice; 3. Scribing and taping for hook seams; Fourth, spray real stone paint with a spray gun; Fifth, after all the spraying is done, you can remove the tape and trace the line.

<><Can you spray another layer of real stone paint?

First of all, the cause of the real stone paint spraying is clearly solved, if it is caused by construction factors can be remedied, if it is the paint itself problem, no matter which method is used to remedy it is unlikely to repair well. Real stone paint is a kind of color sand stone and emulsion according to the proportion of the paint, it can be said that the uniformity of the paint will be affected, if the paint is added to the pigment color, it is easy to affect the nature of the coating.

How to choose real stone paint

1. Choose a regular manufacturer.

When choosing real stone paint, you should also pay attention to the manufacturer, like a good manufacturer also has advanced equipment and technology, but also has a professional R & D team, so as to produce a good quality of real stone paint, at the same time, the product packaging and identification will be relatively complete, ** will also be more reasonable.

2. Judgment of the color of real stone paint.

Secondly, when choosing real stone paint, you should also look at its color. Like some bad quality real stone paint, because the small factory in order to save some costs, will use in order to save costs, will use some cheap glue, this will cause the coating water resistance, stain resistance will be relatively poor, there is a real stone paint using water-based slurry color, when the color is the same, it is easy to bloom after spraying.

3. Color difference and quality stability.

If the source of the sand is different, there is no way to keep the color number the same, and there will be a color difference between batches. Especially for some small factories, the equipment and productivity are relatively low, the same batch of products appear in different colors, and the color difference will be more serious, which will also affect the quality of the project.

About the real stone paint spray can be sprayed another layer of related content is introduced here, first to solve the cause of the real stone paint spray clearly, if the construction factors can be remedied, if the paint itself is a problem, no matter which method is used to remedy it is unlikely to repair well.

The primer of real stone paint can improve the adhesion of real stone paint, increase the fullness of real stone paint, provide alkali resistance, provide anti-corrosion function, etc., and at the same time can ensure the uniform absorption of real stone paint, so that the real stone paint system can play the best effect.

Here's what it does:

1.Closure: Some walls are more alkaline, and alkaline flowers are produced after being soaked in moisture and water, the scientific name is "pan alkali", which causes the formation of crater-like protrusions on the surface of the paint film, and forms a layer of alkali cream on the surface of the paint film in serious cases, which eventually destroys the paint film.

Primers can act as a sealant to alleviate this. However, if the walls of your house are dry and the floors are higher, it may not be a problem if you don't use it, but it is recommended that you use insurance.

2.Adhesion: The emulsion content in the primer is higher and the adhesion is stronger. It can improve the adhesion between real stone paint and the wall.

3.Filling: If your wall is not alkaline and relatively flat, you can do without primer, of course it is better to use it.

Applying a layer of sealing primer before painting real stone paint can not only save decoration costs, but also have the advantage of getting twice the result with half the effort in the long run and decorative effect. At the same time, the good adhesion of the primer makes the wall smoother, making the real stone paint easier to paint, and reducing the amount of real stone paint. In this way, the wall not only avoids paint sickness, but also helps to maintain the painting effect for a longer time.

All ridge-containing materials for exterior paints: water, film-forming additives, hardening agents, ethylene glycol, cellulose, multifunctional additives, emulsions, preservatives, defoamers.

Exterior wall real stone paint construction technology scheme.

First, the importance of engineering.

Real stone paint as an exterior wall finish is of great importance, first-class products and careful construction, in order to make the two perfect combination, to create a first-class model project. We will implement a comprehensive quality management system according to the requirements of the Chuangbei project, and strive to achieve a first-class model and standardized project.

Second, the construction steps and methods.

1. Check whether the flatness and lines of the main wall are straight and clear, and require the surface of the base layer to be smooth and dry (the cement mortar surface should be maintained for more than 15 days), without floating ash, asphalt and other stains, and pH 10, moisture content of 10%.

2. The floating layer should be shoveled off the old cement surface to ensure that the base is firm, remove the impurities on the wall, repair the porous and rough base surface, and then use the grinding wheel to grind the old beam.

3. According to the requirements of decoration, use cement mortar or tape paper to divide the base surface into the required graphics (each division surface should not be larger.)

4. Bottom coat construction.

a.Neutralization treatment: The alkaline wall is neutralized with a special neutralizer to ensure that the wall is not alkaline after construction, and the dosage is approximate.

b.Primer construction: Rinse the neutralized wall with water, and after the wall is dry, carry out primer construction and primer dosage.

c.The undercoat can be applied by brush, roller or spray.

5. Main coating (real stone paint) construction: after the bottom coating is completely dry (generally takes 4-6 hours), the construction can be carried out, and the test spraying is carried out first according to different decoration requirements to determine the pressure, spray gun caliber and spraying amount required for construction, generally 5kg m2.

a.Monochrome main coating: It is advisable to spray it in two times. Before the first coating film is dry, the second coat can be sprayed.

b.Color-matching main coating: You can choose to spray in batches with a double-tube stone paint spray gun or a single-tube stone paint spray gun.

6. Auxiliary treatment: remove the dividing tape and carry out hook treatment according to the decoration needs.

7. Overlay layer (overshadow varnish) construction: construction can only be carried out after the main coating is completely dry (generally about 48 hours), and it can be brushed or rolled with varnish.

Everyone has a basic understanding of real stone paint. It is an imitation marble or granite paint with a decorative effect, similar to marble and granite. It is suitable for the interior and exterior decoration of various buildings.

So do you know how real stone paint is constructed? What are the construction procedures to ensure the quality of construction?

1.Real Stone Paint Building Base Surface Protection Program:

1) Before construction, the finished products such as facing bricks, doors and windows of civil buildings should be protected by pasting newspapers and other methods to prevent pollution. At the same time, floating dust or other contaminants should be removed from the base surface. (2) Before the installation of construction scaffolding, the firmness of the construction scaffold should be checked, and Party A should be negotiated in advance to strengthen the unstable scaffolding.

2.Preparation steps for the base surface of real stone paint:

1) The new wall needs to be fully maintained and dried (the moisture content is not more than 8); For old walls that have been peeled off by moisture, the bottom layer needs to be re-sanded. Only in this way can the spraying of real stone paint paint be carried out.

2) The base surface should be smooth and tidy, and the corner line should be straight, without oil, floating dust or other pollutants.

3) The adhesion of the original old paint on the old wall or other bottom surface should be determined by test; If the adhesion is poor, it must be completely removed.

3.Moisture-proof primer spraying procedure: Before spraying the paint, spray a layer of moisture-proof primer evenly on the base surface and seal it to avoid contaminating the quality of the bottom surface of the real stone paint due to leakage and moisture permeability. The drying time of the moisture-proof primer is about 60 minutes.

4.Real stone paint spraying process: After the moisture-proof primer is dried, the real stone paint spraying construction can be carried out.

When spraying the host material, first stir the host material well to make it evenly mixed, and then arrange the same entire surface, the same integral column, beam and plate surface at once, without leaving the connecting surface to ensure consistency of color and thickness.

5.Surface polishing procedure: Before spraying the waterproof protective layer, you should use tools such as ordinary sandpaper to grind off the floating sand and sharp-angled sand particles on the dry coating surface to make it smooth to increase the beauty of the coating. Real stone paints the surface while ensuring that the protection is completely covered with a film.

6.Steps to spray the waterproof protective film: The waterproof protective film must be sprayed after the stone paint is completely dry.

Before spraying the waterproof protective film, the air pressure of the oil gun can be used to blow up the initially polished stone powder, increasing the bond between the face oil and the real stone paint. 7.Procedures for cleaning the construction site:

Because during the construction process, a small amount of material will inevitably contaminate the surrounding objects, so after completing the construction of the real stone paint paint, please tear off the protective paper first, and then use a shovel blade and sand to remove some contaminants, which should be cleaned to make the site clean, and then handed over to acceptance. In short, the construction in strict accordance with the prescribed construction methods can not only promote the construction process of real stone paint, but also ensure the construction quality of real stone paint and effectively extend its service life.
