Six painting techniques of household putty powder:

1、選擇合適的膩子，與底漆有良好的附著性和機械強度，更要有良好的施工性能，即良好的刮涂性和填平性，適宜的干燥性，收縮要小，耐打磨。

1. Select the appropriate putty, and the primer has good adhesion and mechanical strength, but also has good construction performance, that is, good scraping and filling properties, suitable drying, small shrinkage and grinding resistance.

2、對防腐要求高的坑穴填補在調配膩子時，一般不用水作為調節劑，直接用底漆加入一定比例的填料。

2. For the pit filling with high anti-corrosion requirements, when mixing putty, water is not used as the regulator, and a certain proportion of filler is directly added into the primer.

3、針對木器、混凝土等使用的膩子在調配時，多用石膏粉、水、樹脂、助劑等混合。如使用色漆，石膏粉要適當減少;使用清油、清漆、光漆，則石膏粉可適量多些。

3. For the putty used in wood and concrete, gypsum powder, water, resin and additives are often mixed. If paint is used, gypsum powder should be reduced appropriately; if clear oil, varnish and varnish are used, gypsum powder can be appropriate and more.

4、刮涂膩子的程序是在底漆實際干燥后→用刮刀刮涂膩子→干燥→用嵌刀清除多余膩子及粉塵→刮第二次膩子→干燥→打磨，清除粉塵→刮第三次膩子。精細的工程要涂刮多次膩子，每一次不宜過厚，一般應在0.5mm以下，否則不易干透或收縮開裂。刮涂多道膩子時，應按先局部填孔，再統刮和刮稀的程序操作。

4. The procedure of scraping and applying putty is as follows: after the primer is actually dry → apply putty with scraper → dry → remove excess putty and dust with inlay knife → scrape putty for the second time → dry → grind and remove dust → scrape putty for the third time. Fine works should be painted with putty for many times, each time should not be too thick, generally should be less than 0.5mm, otherwise it is not easy to dry out or shrink and crack. When scraping and applying multi-layer putty, it should be operated according to the procedure of filling holes locally, then scraping and scraping.

5、一般刮膩子的步驟是“先上后刮”即先填上膩子攤滿后再收刮平整，要用力按刮板，使刮板與物面傾斜50°-60°，遇到曲面施工時，可用膠皮制的刮板代替硬質刮板使用，使質量優良。刮涂時，來回刮一兩次，但不可往返的次數太多。對于油性膩子，往復的次數過多，會將膩子中的油分擠出來，封閉在膩子表面，影響干燥。

5. Generally, the process of putty scraping is "first, then scraping", that is, filling the putty first, spreading it, and then leveling. Press the scraper with force to make the scraper and the surface of the object incline 50 ° to 60 ° to meet the curved surface construction, the scraper made of rubber can be used instead of the hard scraper to make the quality excellent. When scraping, scrape back and forth once or twice, but there are too many times that can't go back and forth. For oily putty, too many times of reciprocating will squeeze out the oil in the putty and seal on the surface of putty, which will affect the drying.

6、刮涂時，將工件低缺部位填平至高接觸面為原則，即對凹凸不平的物面，為凸部分為準，形成水平，對高裝飾性的涂裝，膩子一般刮涂三道。干燥完后，可用砂紙、磨石或水砂紙打磨，打磨完畢，才可涂裝面漆。

6. When scraping and coating, the principle is to fill the low missing part of the workpiece to the high contact surface, that is, for the uneven surface, the convex part shall prevail, forming a level. For high decorative coating, putty is generally applied for three times. After drying, sandpaper, grindstone or water sand paper can be used for grinding, and finishing coat can be applied after polishing.
