多彩花岗岩（水包砂）
施工指南
第1步：基面处理程序
由于基面的状况直接关系到多彩水包砂的施工质量，因此在装修前，必须对基面认真检查验收。
现将具体要求介绍如下：
1) 于刚建成的新墙，需要充分养护，干燥；对于已受潮剥离的旧墙，则需重新做底
层批荡，然后才能进行“美涂士”多彩水包砂的一系列喷涂施工。
2) 基面应平整、洁净，不得有油污，浮灰或其它污染物。
3) 对旧墙体或其它基面上原有的旧涂料，应经试验确认其附著性；若附著性差，则必须彻底铲除。
第2步：批刮找平腻子，打磨平整。
（1）批刮腻子应使用抹子、刮板或钢批进行施工，从上向下批刮。每遍腻子不能刮涂太厚，过厚易产生龟裂、脱落等弊病。通常外墙腻子一道在0.5~1.0mm左右。
（2）腻子通常批刮两遍，两遍腻子的间隔时间不能过短，一定要在第一道腻子干燥后，再披刮第二道腻子。
（3）批刮腻子时不要过多往返刮涂，以免出现卷皮、脱落或将腻子中的胶料挤出，封住表面不易干燥。
（4）批刮腻子时，要注意手法，食指压紧刀片，用力将腻子压进缺陷内，要填满、填实，将四周的腻子收刮干净，使腻子痕迹尽量减少。
（5）待腻子完全干透后（晴天一般6个小时）用对应的砂纸打磨平整，清扫灰尘。
第3步：施工多彩水包砂底漆
喷漆前先把墙面的灰尘清扫干净，在基面上均匀地喷涂一层底漆，进行封底处理，以免由于基面渗色、透湿，从而污染、溶胀多彩漆主材，影响施工质量。
水性封闭底漆施工时，一般以滚涂比较好，水性封闭底漆干透时间约为4小时。
第4步：沟缝分格
1. 按照设计要求在墙面打好水平，量好尺寸，用墨盒弹好线，定好位置，贴美纹纸作保护。
第5步：喷涂配套有色中涂漆
施工配套实色中涂漆时，使用专用的喷枪喷涂，也可以使用滚涂，必须等第一遍干透后才能施工第二遍。因为实色中涂漆的颜色对最终效果影响很大，必须保证喷涂颜色一致，不能漏喷（滚）、薄喷（滚）。
第6步：喷涂多彩水包砂主材
检查配套实色中涂漆颜色均匀并干透后，喷主材使用专用喷枪，看粒子的粒径大小选择枪口（2.0mm、2.5mm、3.0mm），选好枪嘴口径，空气压缩机气压要达到6kg以上，压力筒压力调节至合适并保持稳定出油量。视样板的花纹，采取斜喷或直喷。距离40cm-70cm，以均匀的速度来回十字走枪，保证均匀满喷。 如果花纹密集度比较高，建议不要一次性喷涂，可以分两次喷涂，一次喷涂密集的话，易流挂和将彩点打出气泡。
第7步：多彩水包砂罩光面漆
主材层完全干透后（晴天时一般24小时干透）才可以喷涂面漆，空压机气压要求6kg以上，喷枪的枪口垂直于墙面，距离30cm-50cm，来回均匀喷洒上去，面漆一般喷一遍。均匀地喷涂一层，不得漏喷。至此多彩水包砂的全部施工程序完成。
Granite Paint (rought surface)
Construction Guide
Step 1: Base Treatment Procedure
Since the condition of the base surface is directly related to the construction quality of Granite Paint, the base surface must be carefully inspected and accepted before decoration.
The specific requirements are now introduced as follows:
1) New walls that have just been built need to be fully maintained and dried; for old walls that have been peeled off due to moisture, they need to be re-primed.
After several layers of spraying, a series of spraying constructions of Maydos Granite Paint can be carried out.
2) The base surface should be smooth and clean, without oil, floating dust or other pollutants.
3) For the original old paint on the old wall or other base surface, the adhesion should be confirmed through tests; if the adhesion is poor, it must be completely eradicated.
Step 2: Scrape and level the putty and polish it smooth.
(1) The putty should be applied with a trowel, scraper or steel batch, and scraped from top to bottom. Do not apply the putty too thickly each time, otherwise it will easily cause cracks, peeling and other defects. Usually the thickness of exterior wall putty is about 0.5~1.0mm.
(2) Putty is usually applied twice, and the interval between the two putties cannot be too short. The first putty must be dried before the second putty is applied.
(3) When scraping putty, do not scrape it back and forth too much to avoid curling, falling off or squeezing out the rubber in the putty, sealing the surface and making it difficult to dry.
(4) When scraping putty, pay attention to the technique, press the blade tightly with your index finger, and press the putty into the defect with force, fill it thoroughly, and scrape away the surrounding putty to minimize the traces of putty.
(5) After the putty is completely dry (usually 6 hours on a sunny day), polish it smooth with the corresponding sandpaper and clean away the dust.
Step 3: Apply Granite Paint primer
Before spraying, clean the dust on the wall first, spray a layer of primer evenly on the base surface, and perform back-sealing treatment to avoid color bleeding and moisture penetration on the base surface, which will contaminate and swell the main material of the multi-colored paint and affect the construction quality.
When applying water-based sealing primer, it is generally better to use roller coating. The drying time of water-based sealing primer is about 4 hours.
Step 4: Divide the grooves into grids
1. Level the wall according to the design requirements, measure the size, use an ink cartridge to stretch the line, determine the position, and stick textured paper for protection.
Step 5: Spray matching midcoat
When constructing the matching solid-color mid-coat, use a special spray gun or roller coating. You must wait for the first coat to dry before applying the second coat. Because the color of the solid-color paint has a great influence on the final effect, it must be ensured that the spray color is consistent, and no leakage (rolling) or thin spraying (rolling) is allowed.
Step 6: Spray the main material of Granite Paint
After checking that the matching solid color medium paint is even and dry, use a special spray gun to spray the main material. Select the gun muzzle (2.0mm, 2.5mm, 3.0mm) based on the size of the particles, select the gun nozzle caliber, and air compressor The air pressure should reach more than 6kg, and the pressure of the pressure cylinder should be adjusted to the appropriate level and maintain a stable oil output. Depending on the pattern of the sample, use oblique spraying or direct spraying. From a distance of 40cm-70cm, move the gun back and forth crosswise at a uniform speed to ensure even and full spraying. If the pattern density is relatively high, it is recommended not to spray it in one go. You can spray it in two times. If the pattern is densely sprayed in one time, it is easy to sag and bubble the colored dots.
Step 7: Overcoat
The topcoat can be sprayed only after the main material layer is completely dry (it usually dries within 24 hours on sunny days). The air compressor pressure is required to be above 6kg. The muzzle of the spray gun is perpendicular to the wall at a distance of 30cm-50cm. Spray it evenly back and forth on the surface. Paint is usually sprayed once. Spray an even layer without missing a layer. At this point, all construction procedures for colorful water-packed sand are completed.
