Six painting techniques of household putty powder:

1、选择合适的腻子，与底漆有良好的附着性和机械强度，更要有良好的施工性能，即良好的刮涂性和填平性，适宜的干燥性，收缩要小，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、对防腐要求高的坑穴填补在调配腻子时，一般不用水作为调节剂，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、针对木器、混凝土等使用的腻子在调配时，多用石膏粉、水、树脂、助剂等混合。如使用色漆，石膏粉要适当减少;使用清油、清漆、光漆，则石膏粉可适量多些。

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、刮涂腻子的程序是在底漆实际干燥后→用刮刀刮涂腻子→干燥→用嵌刀清除多余腻子及粉尘→刮第二次腻子→干燥→打磨，清除粉尘→刮第三次腻子。精细的工程要涂刮多次腻子，每一次不宜过厚，一般应在0.5mm以下，否则不易干透或收缩开裂。刮涂多道腻子时，应按先局部填孔，再统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、一般刮腻子的步骤是“先上后刮”即先填上腻子摊满后再收刮平整，要用力按刮板，使刮板与物面倾斜50°-60°，遇到曲面施工时，可用胶皮制的刮板代替硬质刮板使用，使质量优良。刮涂时，来回刮一两次，但不可往返的次数太多。对于油性腻子，往复的次数过多，会将腻子中的油分挤出来，封闭在腻子表面，影响干燥。

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、刮涂时，将工件低缺部位填平至高接触面为原则，即对凹凸不平的物面，为凸部分为准，形成水平，对高装饰性的涂装，腻子一般刮涂三道。干燥完后，可用砂纸、磨石或水砂纸打磨，打磨完毕，才可涂装面漆。

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.
