| ①首先，关键是要知道用于什么基面，采取什么施工方式，再选择用什么材料，不是有一个界面剂配方就什么都用的上。如果用抹刀抹（单组分常用施工方式），就不用担心界面剂过稠，配方中加水量一般较低（25%左右），抹完后界面剂没干时，马上抹砂浆，粘结力是最好的；如果用刷子刷涂施工，就不能用粗砂，多加一些胶粉，提高用水量（40%左右），但是成本会提高；还有就是用喷枪喷涂施工。 First of all, the key is to know what base surface to use, what construction method to adopt, and what materials to use, not a formula of interface agent on everything. If you use a spatula (one component commonly used construction method), you don't need to worry about the interface agent is too thick, the amount of water added in the formula is generally low (about 25%). When the interface agent is not dry after finishing, the bonding force is the best. If you use a brush to paint, you can't use coarse sand, add more rubber powder, and increase the water consumption (40%). % About), but the cost will increase; there is spray gun spraying construction. ②界面剂用粗砂会比细砂强度高些；如果胶粉质量不好，很难做出界面拉毛效果。 (2) Coarse sand used as interfacial agent has higher strength than fine sand; if the quality of rubber powder is not good, it is difficult to make interfacial roughening effect. |
