SURFACE PRETREATMENT
表面預先處理

Quality built from the base

Mechanical preparation: In many cases surfaces such as concrete, metal or existing previous coatings are contaminated. These areas need to be cleaned mechanically. In general all surfaces must be dry, clean and free of oil, grease, dust and other contaminants. Various methods like grinding, grit blasting or blast-cleaning with sand or water produce a rough, even surface in addition to cleaning it thoroughly.

Chemical preparation: Priming is always recommended after preparation of the surface area. Primers secure pore density, level the surface, take care of voids and subsequently improve adhesion properties. Before continuing with next layer the surface has to be tack free. The timeframe to observe depends on whether or not a 1-Part or a 2-Part Primer system is used.

高品質從基底開始建立

物理性準備：通常情況下，混凝土、金屬面或已經存在的塗層表面等都已經受到污染，因此表面需要進行機械性清洗。一般來說，所有的表面都必須乾燥、清潔、無油脂、無灰塵和無其他的污染物。打磨、噴沙、利用水或沙進行的高壓清洗等各種方法可以能徹底清潔表面，甚至可以產生一個粗糙的表面。

化學性準備：表面準備好後，始終建議塗抹底油，底油可以確保填密表面的破孔、可以平整表面和修保裂縫，並可以增加和防水層的粘附能力。在塗抹下一層前，底油必須已經表乾，表乾時間聚取決於底油的比例。
