关于铺瓷砖,最常见的问题之一就是——“可以在现有瓷砖上铺设新瓷砖吗?”。这个问题有两个方面。从技术上讲,这是可以做到的,但在实践中通常会避免这样做。这种铺设方式取决于现有瓷砖的状况。由于这些瓷砖已经磨损、受潮损坏或表面不平整,因此不建议在现有瓷砖上铺设。此外,重量和吸湿性等因素也会让您重新考虑这个方案。
在开始之前:
首先,检查您现有瓷砖的当前状态。这一点非常重要,因为它们将作为您新瓷砖的基础。您的瓷砖铺设需要密封良好并与基底粘合。如果现有的瓷砖铺设稳固,并且瓷砖与底层地面之间没有空隙,那么您可以铺设新瓷砖。要检查是否有空隙,只需敲击瓷砖并听是否有空洞的声音即可。这些空隙通常是由于瓷砖和地面基层之间缺乏粘合剂造成的,但也可能是由于地震或附近有建筑工地导致的。
另请考虑:
- 如果基底是石膏板,请考虑两层瓷砖带来的额外重量。石膏板每平方厘米有最大承重限制,超过此限制可能会导致结构损坏。
- 并非所有类型的粘合剂都适合在瓷砖上铺设瓷砖。由于瓷砖旨在承受潮湿并尽可能减少吸水,大多数粘合剂将无法发挥作用。
- 在铺设瓷砖时,请记住您的地面高度将增加一到三厘米。这意味着任何门框、厨房电器、家具和浴室储物柜都需要进行相应的调整。您可以使用门槛条来平整或过渡两种类型的地面。如果您只需要铺设房间的一半,先拆除旧瓷砖会更美观。
在开始铺设瓷砖之前
如果您已经考虑了这些要求,并且没有听到空洞的声音,那么您可以着手铺设瓷砖。在此之前,您应该彻底清洁现有的陶瓷瓷砖。这一步非常必要,但经常被忽视。实际上,这样做不仅是为了美观,更是因为任何油脂或灰尘都会导致瓷砖粘合剂难以附着。因此,请确保彻底清除所有油污,并确保填缝剂也处于完美状态。
拆除旧瓷砖
如果现有的瓷砖不符合要求,存在空隙、表面不平整或过重,那么拆除它们是更好的选择。根据底层的不同,有不同的拆除方法。通常,最简单的方法是拆除衬板(如果使用了的话)。当然,拆除瓷砖的成本更高,这就是为什么许多人一开始就选择这种(直接覆盖的)方法。
结论
- 可以直接在瓷砖上铺瓷砖吗?可以。
- 应该这样做吗?大多数情况下——不建议。
什么时候可以这样做?
- 如果您现有的瓷砖较小且较薄,并且墙壁能够承受第二层瓷砖的重量。
- 当粘合剂能被瓷砖吸收时。
- 当您能在不同类型的地面之间实现平滑美观的过渡,并且您已经考虑到额外的一层瓷砖会使地面升高 1 到 3 厘米时。

Remove the glaze off existing tile with a sander or grinder for better adhesion then use a flexbond thinset by customs it acts as a crack isolation membrane also and apply a 1/8 to 1/4 coating over existing tile that makes your substrate stronger and a fresh new and clean suface to set on.then use a POLYMER-MODIFIED THIN-SET MORTAR ( the expensive bag)such as versabond by customs to set yor tile or stone on and you should have no issues.now remember adhesion is everything in this buisness and your job is only good as the person who set the existing tile before you so make sure it has a good bond and no hollows. good luck.......

My existing tile is in good shape, no cracks, loose tile, etc. They are the 8" squares...I would like to tile over this tile with a larger tile maybe even 16x16....would that be a good idea or do you have to stick with the same size tile.

I made sure I read this article thoroughly, before I got tile-on- tile application done. It was not as stressful as I thought it would be. Easy and not a big issue when the tiles are more or less of the same size. In India the best tile on tile adhesive is Roff non-skid adhesive, it just stuck right on and was not messy either.

We are remodeling our bathroom and the existing floor is marble. We would like to change the floor to porcelain tile. Is it okay to lay the porcelain tile over the existing marble floor?
