北美油漆paint与stain的不同之处

The main difference between paint and stain is that paint sits on top of the surface rather than seeping into the surface. Paint also needs to be painted onto surfaces that have been primed first, while stain does not need a primer. Typically, stain is only applied as one coat whereas paint also takes more time to apply because it needs several coats of application.

油漆和stain之间的主要区别在于油漆位于表面顶部而不是渗入表面。 油漆也需要先涂在已涂底漆的表面上，而stain则不需要底漆。 通常，stain仅涂覆一层，而油漆也需要更多时间来涂覆，因为它需要涂覆几层。

It is important to note that once a surface has been painted, it cannot be stained unless all the paint is stripped down the bare substrate and prepped properly. A painted surface is in essence protected and stain will not penetrate the substrate (ie., wood) unless free from all previous paint and chemicals. Also, new wood can be painted, but must cure for a certain period of time before staining can even occur.

需要注意的是，表面涂漆后，除非将所有油漆从裸露的基材上剥离并进行适当准备，否则它无法使用stain染色。 涂漆表面本质上受到保护，stain不会渗透基材（即木材），除非没有以前的所有油漆和化学品。 此外，新木材可以涂漆，但必须固化一定时间才能用stain染色。

Just as interior and exterior paint comes in various colors and sheens (flat, matte, satin, eggshell, semi-gloss, gloss, etc.), both interior and exterior stain comes in a variety of colors, sheens (flat, matte, satin, etc.) and opacity (clear, semi-transparent, solid, etc.) and there are many different finishes that can be applied afterward to get a desired look. Wood stains add color to natural wood while finishes seal the wood and protect it from moisture. Examples of finishes are lacquer, polyurethane, varnish, wax, and shellac to name a few and there are both water-based an oil-based versions well.

正如室内外涂料有各种颜色和光泽（平光、哑光、缎光、蛋壳、半光、光泽等）一样，室内外stain也有多种颜色和光泽（平光、哑光、缎光等） 等）和不透明度（透明、半透明、实心等），并且有许多不同的饰面可以随后应用以获得所需的外观。 木材着色剂为天然木材增添色彩，而饰面则密封木材并防止其受潮。 饰面的例子有清漆、聚氨酯、清漆、蜡和虫胶等，并且有水基和油基两种版本。
