仿断桥铝门窗漆片具备特别好的扮饰性和靠得住的安全性，但不恰当的选材和不规范的动工往往使涂膜发花和出现裂缝。准确选用各道涂装材料是保障仿断桥铝门窗漆片涂装成功的首要因素，而避免涂膜出现裂缝和发花的关键是改进泥子的选料和配比。配合制造不一样功能的多道泥子，加强泥子的黏合性、软而韧性和平而光滑性，认为合适而使用多次找平、逐步逐渐变化的办法，使裂隙变型量逐步开释，因此使涂层外表难于出现裂缝。形成高平整度泥子表层，可避免断桥铝门窗扮饰面光泽翘棱均的现象。

影响断桥铝门窗涂料涂装质量的因素

1.1涂层出现裂缝
仿断桥铝门窗涂装对平整度的要求极高，大大增加了泥子层的厚度，而平常的泥子和较厚的泥子层，经风吹雨淋和干湿交替变动，更易萌生出现裂缝。裂隙不止关系到扮饰品质，严重的还会影响到仿断桥铝门窗漆片的性能和生存的年限。

为了避免漆片饰面的出现裂缝，仿断桥铝门窗涂装外墙泥子应具备一定的软而韧性，以覆盖基层的微小裂纹，消弭墙体和涂层之间的应力，使裂隙变型量逐步开释，因此使涂层外表难于出现裂缝。

1.2涂层剥离
涂层剥离有可能是因为基层处置不合适，如外表的污物、锈垢和化学品等未彻底整理整洁；还是在底漆未干透前涂覆漆片；还是涂膜太厚，以及在潮润或发霉的基层上涂装漆片，涂膜与基层的黏着力不好等，都有可能引动涂层严重出现裂缝，甚至于发生剥离现象。

用平常的泥子二次抹涂的办法不可以达到断桥铝门窗高平整度基层的要求，而应当经过选用不一样功能的多种泥子，采取多次找平的办法来成功实现。
