Today, the model company will take you to understand the three tips in the construction sand table model making.

1.洗。建筑模型制作过程中，总会遇到“洗”的步骤，它的作用是让油漆固化，同时让模型“旧化”（看起来更具真实感）。现在大多数人都使用煤油作为“洗”的原料，但煤油的挥发性不好，不易干，而且容易腐蚀粘结点。

1. Wash. In the process of building model making, there is always a "wash" step. Its function is to solidify the paint and make the model "old" (more realistic). Nowadays, most people use kerosene as the raw material for "washing", but kerosene is not volatile, not easy to dry, and easy to corrode and bond.

2.水贴纸问题。水贴纸比较娇气，搁置时间一长，就容易干裂，所以在建筑模型买回家后，要将水贴纸用食品保鲜膜包好，放在冰箱里，到使用时再取出。

2. Water stickers. Water stickers are delicate and easy to dry and crack after a long time. Therefore, after the building model is bought, wrap the water stickers with food preservative film, put them in the refrigerator and take them out when they are used.
              

如果水贴纸已经干裂，用国产“天使”牌模型漆的K22号“光油”稀释后，喷在水贴纸的表面，多喷几次，就能够修复。

If the water sticker has been cracked, dilute it with K22 "varnish" of domestic "angel" brand model paint, spray it on the surface of the water sticker, and spray it several times more, then it can be repaired.

3.溜缝胶水。目前市面上出售的“溜缝胶水”只有“田宫”的产品，但要20元一瓶 （40ml），其实到化工商店买一瓶乙酸乙酯，效果基本一样，但便宜多了。但是要注意存放。

3. Slip glue. At present, only Tiangong glue is sold on the market, but it costs 20 yuan per bottle (40ml). In fact, if you buy a bottle of ethyl acetate from a chemical store, the effect is basically the same, but it's much cheaper. But pay attention to storage.
