（2）腻子粉的种类

(2) Types of putty powder

市面上的腻子粉主要分为普通腻子和耐水腻子，建议选择耐水腻子！

The putty powder on the market is mainly divided into ordinary putty and water-resistant putty. It is recommended to choose water-resistant putty!

强度；耐水腻子在粘结强度在标准状态粘结强度达到0.50Mpa以上，而普通型仅为0.30Mpa以上；

strength; The bonding strength of water-resistant putty is in the standard state, and the bonding strength is more than 0.50mpa, while that of ordinary putty is only more than 0.30mpa;

使用寿命；耐水腻子在水中侵泡48小时仍然不会起皮、开裂脱落，使用寿命达到10年以上；而普通型的侵泡后就会脱落，使用寿命3~5年。

service life; The waterproof putty will not peel, crack and fall off after soaking in water for 48 hours, and its service life will reach more than 10 years; The ordinary type will fall off after bubble invasion, with a service life of 3 ~ 5 years.

环保；耐水腻子粘结力高于一般腻子，所以批刮时不用添加胶水，更环保。

environment protection The adhesion of water-resistant putty is higher than that of ordinary putty, so there is no need to add glue during scraping, which is more environmentally friendly.

成本；耐水腻子的比普通腻子更贵，价格相差1~2倍，硬度较高，打磨的会更费力，工期更长些，所以综合成本也会高一些。装修时可以搭配着来使用，比如天花板就可以使用一般腻子。

Cost; Water resistant putty is more expensive than ordinary putty. The price difference is 1 ~ 2 times, the hardness is higher, the polishing will be more laborious, and the construction period will be longer, so the comprehensive cost will be higher. When decorating, it can be used together. For example, general putty can be used for the ceiling.

综合上述，耐水腻子在家装中性能表现的更优异，特别适用于南方或延江延海容易潮湿进水的地方，无特殊情况，都应该选择耐水腻子。

Based on the above, the performance of water-resistant putty is better in home decoration. It is especially suitable for places in the South or Yanjiang Yanhai where water is easy to enter. Water resistant putty should be selected without special circumstances.

（3）看环保性

(3) Look at environmental protection

在选购乳胶漆时，大家特别注重环保性能。而选择腻子粉却没那么重视，而腻子粉的用量要比乳胶漆的用量多的多。

When purchasing latex paint, we pay special attention to environmental protection performance. The choice of putty powder is not so important, and the amount of putty powder is much more than that of emulsion paint.
