瓷砖背胶严格来说,是一种瓷砖背面界面的处理剂。针对现在很多地砖上墙(如玻化砖)的做法,针对这些非瓷片砖面积大、厚重、表面光滑吸水率低等特点,可提高砖材背面粘合材料的粘合强度,有效防止空鼓、起壳、脱落等问题。各有千秋,综合众多铺贴工的反馈信息,还是提倡用瓷砖粘结剂(背胶)比较多人,首先水性环保无毒,还带防水作用,耐低温,耐高温,耐冲击力,而且粘结力超强,持久,可以达到三十年不空鼓,不脱落!一劳永固,从此不用担心瓷砖空鼓,脱落的问题。

瓷砖胶看起来跟水泥很像,也是加水搅匀,薄薄地涂抹在瓷砖背面,而背胶是胶状流体,先涂抹在瓷砖背面,然后厚厚地涂抹一层水泥砂浆混合物,前者是薄贴,后者是厚贴瓷砖背胶是一种乳液产品,怕水怕热,怕老化,现在很多地砖上墙或者全瓷砖都用背胶。我认为是一种不合适的做法,早晚会被市场淘汰,等过几年背胶老化瓷砖空鼓了后悔也晚了,比如有人讨论单元房是一个厕所好还是两个厕所好,相同的成本你选哪个?还有人问吊顶好不好,如果吊顶不多花钱,你选哪个?再就是瓷砖胶,不是比正常铺贵的话,你选哪个?

它的作用就是为传统的粘接砂浆的对砖和对墙的两个界面贡献渗透粘合力,但在厚度方向上承受抗拉和抗剪的,还是传统的
粘接砂浆,而粘接砂浆属于现拌,灰沙比和水灰比都是由工人师傅自行按习惯掌握,粘贴质量受人为因素影响大。因为国内瓷砖胶很难达到要求,需要借助背胶进行黏贴。背胶只能临时粘贴不可长期依赖背胶。建议大家选择对应等级的瓷砖胶进行薄贴。不要跟风,否则最后吃亏的只能是自己,不要做厂家的实验品。

需要,贴卫生间瓷砖时必须要用背胶,因卫生间比较潮湿,利用背胶才会让瓷砖变的更加牢固。还能提高砖背粘合材料的粘合度,防止出现缝隙、剥落、流挂等现象。但购买的背胶必须要确保水性环保无毒,具有防水效果,耐低高温和耐用等,这样的背胶才不会出现空鼓和掉落情况。
二、瓷砖背胶使用需注意什么
1、安装瓷砖胶时,先确定环境的温度,不能低于5度,也不能高于35度,否则就会影响胶水粘度。若遇到多尘或是阴雨天气的话必须要推迟施工更好。
2、背胶施工之前,施工面必须要清洁干净,不能有灰尘、污渍,还要避免在潮湿的环境下使用。且胶粘剂开封后可直接使用,完全无需加水进行稀释。
3、将粘合剂涂在瓷砖背面后,必须等先到应用变得透明后,才能使用水泥砂浆或其他材料进行铺路工作。但要注意在粘贴瓷砖的过程当中,必须要保证瓷砖与砂浆要很好地结合,从而才能直接避免会出现一些缝隙问题。
4、当瓷砖施工完成之后,必须先要做好成品的保护工作,才可以预防后续施工时对墙面再来一定的破坏,影响后期正常施工。

回答3:

当然需要,我们在贴卫生间瓷砖的时候,一定要使用背胶,因为卫生间比较潮湿,所以使用背胶的话能够更牢固一些。

回答4:

需要。因为使用背胶能使瓷砖贴得更加牢固,而且防水性能也会更好。

回答5:

需要使用背胶。因为毕竟卫生间比较潮湿,为了避免以后脱落,使用背胶会粘得更加牢固。
