2) Construction requirements

Climate conditions:  
Temperature: 5 ℃-35 ℃;
Relative air humidity: less than 80%;
After the construction is completed, the surrounding temperature shall not be lower than 5 ℃ within 24 hours.

Wall surface requirements:  
Wall humidity: less than 10%;
Wall PH value: less than 10;
The wall surface shall be solid and flat. The wall body shall have no bulking, efflorescence, cracks, or floating dust; shall be thoroughly dry; and shall be neutral or slight alkaline and clean. And the caved corner and bulged corner are vertical.

3) Construction Tools
mortarboard, ordinary trowel, mixing bucket, high-speed mixer, measuring cup, special smoothening trowel, ladder, textured paper and other protective materials; separation bar (optional), power source, towel, abrasive paper (cloth), special mold, beater , etc.

4) Wall inspection and pre-construction protection
Wall inspection: Ensure that the wall meets the construction requirements, and measure the wall flatness with steel rule. The wall that does not meet the construction requirements shall not be constructed. Otherwise, many problems may arise, such as bulking, peeling, shedding, cracks, efflorescence and change in color.
Pre-construction protection: After ensuring that the wall base is flat and meets the construction requirements through wall inspection, cover the surrounding 50 cm outside the construction area with protective film or masking tape. After completing the protection, in order to uniform water absorption of wall surface, the back over treatment shall be conducted before construction.

① Preparation of closed bottom oil
Closed bottom oil is produced through mixing special emulsion for wind-washed stone and a certain amount of water, and the ratio between special emulsion for wind-washed stone and water is 1 : 10.
When mixing the bottom oil, first add the standard amount of clean water, and then add emulsion. The oil can be used after being mixed well.

② Brushwork of closed bottom oil
When constructing wind-washed stone products, the material drying time is shortened due to climatic reasons (sunlight), strong water absorption of base and other factors, and therefore the construction workers must brush closed bottom oil on the base materials before constructing wind-washed stone.
Closed bottom oil shall be brushed twice, brush it horizontally for the first and brush it longitudinally for the second pass after it is dry covering all construction surface. The construction can start after the bottom oil is slightly dry without oil flow.
The closed bottom oil mixed at each time shall be used up at that time.

5) Construction craft of Wind-Washed Stone Series Product

Construction process:

First process, raw material mixing

1) Internal-wall wind-washed stone

Ratio of powder and water is 3.5:1
Pour 90% of the water amount into the clean mixing bucket, and left 10% of the water is for adjustment. Slowly pour Wind-Washed Stone powder into the water, and after the powder is emptied out, mix it with an electric mixer. At the beginning period, the powder is hard, and the mixing is difficult. At this time, you can conduct adjustment for many times with the remaining 10% water, but the total water amount shall not exceed the water to be used in the ratio. In the mixing process, in order for better mix effect, leave them for 10 minutes, and the time for mixing raw materials shall last at least 15 minutes.

• It shall be used immediately after being mixed evenly, and the mixing materials shall be used up at the same day;
• In the course of use, when it is found that the materials become dry, no water is needed, only mix it again with the
mixer, or discoloration may be caused by wrong water amount, and cracks and color difference may be caused easily
after the construction.

2) External-wall wind-washed stone
Ratio of plaster coating materials: The ratio between powder and special emulsion is 1 : 0.15 with appropriate water amount (the water is added appropriately for construction).
Ratio of spray coating materials: The ratio between powder, special emulsion and water is 1: 0.30 : 0.12.
First add the emulsion in the beating bucket, add 85% of the total water amount, and mix it; then add powder to mix for 10 minutes and leave it for 5 minutes; finally add the remaining 15% of the total water amount, and mix it for 5 minutes.

• A person shall be specially designated to be responsible for the powder mixing, so as to ensure the consistency of materials ratio.
• The ratio of powder and emulsion must be mixed according to the standard above. If the mixed material is too thin, the powder and emulsion can together be added according to the standard ratio, and powder or emulsion shall not be added separately; if the mixed material is too thick, an appropriate amount of clear water can be added for regulation, and separate emulsion regulation shall be prohibited.

Second process,Use of lower coating materials

Lower coating materials may be used or not, and they shall be used under the following conditions:
Inconsistent base color, inconsistent water absorption (for example, some places of the cement base is brushed with latex paint and some places are not brushed), different base materials (like a wall having cement interface and water putty interface), etc.
The fine aggregate wind-washed stone in the construction must use lower coating materials.

The third process,Material plaster coating

The plaster coating method is as same as that of cement mortar, and one wall shall be completed once; if it cannot be completed once due to too large area, the wall can be divided with cloth tape for separate construction.
When brushing each part, it cannot be stopped midway; if it has to stop, the original joints of the house structure shall be selected, so as to avoid the appearance of joint.

The fourth process, standard texture production

① Travertine
After the completion of plaster coating, it shall be even and uniform, with a
thickness of about one sand grain. Smoothly move the ordinary trowel in a cycle on the surface of the wall so as to make the sand grain create sand pit or short thread, and then carry out slight smoothening with smoothening trowel and control the smoothening time when carrying out smoothening.

② Frosted finishing
The plaster coating shall be even and uniform, slightly thicker than in travertine texture, and do texture after the completion of plaster coating. The method is to make circle-shaped friction with foam on the wall surface to make the gravel emerge on the surface. It is completed after the appearance of high ridges raised by irregular sand pit and fine powder. After the completion of texture, slightly flatten the raised high edges with smoothening trowel, requiring a little more flat.

③ Freehand brushwork
The plaster coating shall be even, with a same thickness of frosted finishing, and the texture can be done after the completion of plaster coating. Make semi-circular rotation with foam from the inside to outside, rub alternatively towards left and towards right until slurry and gravel draw out an arc and irregular raised edge. After the completion of texture, slightly flatten the raised edge with smoothening trowel, requiring slightly less flat, which is contrary to the frosted finishing.

④ Small stream
The plaster coating shall be even, with appropriate thickness, and the texture can be made after the completion of plaster coating. Special brush is used for special tool, and the texture shall be made straightly and evenly. Just brush fine threads with brush on the wall surface. In addition, it can be carried out according to the customers' requirements. If customers need coarse deep lines, construction workers can use more force when making it, and thus the texture will be thick and deep.

⑤ Pottery pattern
The plaster coating shall be even, thicker than any other kinds of texture plaster coating. After the completion of plaster coating, use a special pottery tool to make parallel pulling lines, and the drawn lines shall be straight and even, with consistent texture. As for the wall with a large span, it cannot be pulled to the terminal point at one time, and the construction workers shall stagger the stopping positions of the previous pulling line and the next one, so as to avoid the appearance of homogeneous joint interface.

⑥ The multilayer coating materials
The multilayer coating materials for external-wall decoration can produce a variety of texture patterns, and construction workers can create personalized patterns according to customers' demand.

3. Daily cleaning and maintenance of diatom ooze finishing

1) The balance and regulation effect of Dajin Wind-Washed stone can effectively reduce static phenomenon, so the finishing after construction cannot stick dust easily, and it can be cleaned only after slightly dusting it with chicken brush when in maintenance.

2) As for dry stains or writing, they can be removed through slight wiping of rubber or No. 600 fine abrasive paper.

3) As for the splashed liquid stains (such as ink or other colored liquid) on the wall surface, the light colored stains can be removed through slight wiping of clean white towel with bleacher; the deep stains can be scraped with scraper, then wet it with clear water, and re-patch it with the paint of the same finishing color after it becomes dry.
