解决了！是的，你可以铺砖

问：我想重新铺地我的地板，但我宁愿不要先穿过剥夺现有地板的麻烦。能够you tile over tile in order to save time?

A:The short answer is, most likely, yes. If your tiles are in relatively good condition—evenly placed, without cracks, and not appearing to retain any moisture—then you can probably leave them underneath your new layer of tile when going about installing a new floor or even a backsplash.

Assess the existing tile.

Before you begin tiling over tile, conduct a thorough assessment of the base layer to pinpoint any surface irregularities, which can cause foundational problems down the road. Mildew and deep discoloration in the grout often signal an absorption issue–meaning that trapped water has damaged the grout and could thus rot the new tile from below. An absorption issue will fester and worsen when the tiles are covered up. Likewise, if the original tiles were not properly installed, the new overlaying tiles won’t lie flat or line up. If you do discover either of these issues, it’s better to start from scratch than to tile over the existing floor.

Prepare the surface for installation.

Tiling over an uneven surface will give you less-than-stellar results, so level out any globs of dried grout with a sander and secure loose tiles with fresh tile adhesive before beginning the project. Then, lay out your new tiles andcut them to fit必要时，墙壁和固定装置周围。一旦所有瓦片切割到大小，将它们移出，使您可以用脱脂肥皂擦洗底层。让表面完全干燥，然后在使用画家的磁带上拍摄项目区域的边缘并铺设塑料床单以保护周围表面。

Lay the groundwork for the new tile in stages.

Generally speaking, thin-set adhesive (also known as thin-set mortar) is great for setting tiles in areas subject to moisture, like bathrooms, while mastic adhesive is best for drier spaces, like kitchens. Scoop the adhesive of choice from its bucket with a trowel and apply a thin layer to a section of tiles only a few feet wide, for starters. Don’t attempt to cover a full floor or backsplash at once; since curing times may vary, you’ll want to set each tile before the bonding agent is too dry to do its job. Score the surface adhesive with the toothed edge of your trowel by drawing straight lines along the wet surface, as these grooves aid in the drying and adhesion process.

当您离开时定位瓦片。

将每个瓷砖设置在您所分配的粘合剂上，并将其牢固地将其压入到位。一旦这些就到位，您可以通过传播胶粘剂，得分和铺设瓷砖旋转，直到您完全覆盖空间。

Tip:To save even more time, apply your adhesive directly to the back of your new tiles rather than prepping the area with thin-set adhesive. This method, though, should be saved for situations where the original tile is in perfect condition and you’re really only looking for a temporary fix until you can attempt a more in-depth renovation project—placement this way won’t set the tiles so securely that they last for generations without needing repair. Take a cue from the blogger atRenov8or, who chose to lay crisp white subway tile over an old layer of beige squares in the kitchen simply by applying silicone adhesive to the back of each individual tile, and placing them over the old tile with spacers in between to save space for even grout lines. While silicone isn’t a recommended adhesive for tiles that will encounter lots of water (a shower wall, for example), this simple fix could cut your project time in half on areas where heavy splashing won’t be a concern in the long run.

Finally, seal off your work.

No matter what kind of adhesive you’ve used beneath the new layer of tiles, you’ll need to apply grout in the grooves between them. This step protects the entire surface from moisture creeping into the seams between each tile and leading to water damage or out-of-sight mildew growth. For the sake of speed, use premixed grout from the hardware store, and apply it quickly in a single round. Or you can choose to混合浆液yourself; just be sure to use an application tube with an opening small enough to fit the troughs you’re filling.

所以，简而言之，只要你正在进行一个相当的声表面，就可以铺砖。现有瓷砖的表面应没有模具和霉变，完全级别（包括灌浆），并且没有任何翘曲或奇怪的瓷砖，可能会干扰平滑的新层。此外，请记住，除非两者下面的基础是混凝土，否则最好不要在现有的瓷砖地板上铺平重新的瓷砖。否则，体重量会导致结构问题。现在起来享受新的，易于安装的瓷砖表面！
