I.Exterior MosaicHow to handle detachment?
The methods for addressing detached exterior wall mosaics vary depending on the extent of the detachment. Here's a breakdown:
1、only the mortar for the tile is detached, while the remaining mortar is intact.
If only the mosaic tiles are detaching, but the cement mortar remains intact, then you should first scrape off the cement mortar from the mosaic tiles. Next, mix the 107 adhesive with the cement to create a paste, and apply it to the back of the mosaic tiles. Finally, directly install the mosaic tiles in their original wall location.
2、Ceramic tiles and mortar are both detaching.
If mosaic tiles are falling off, there's also a situation where both the mosaic tiles and the cement mortar are detaching. In this case, it's best to create small indentations in the original location where the mosaic tiles were installed, then mix 107 adhesive with cement to create a paste. This paste is then applied into the indentations, and the mosaic tiles are re-installed. Finally, the mosaic tiles are pressed firmly against the wall. once the cement mortar has hardened, the work is complete.
II. How to prevent mosaic tiles from detaching
1、When tiling mosaic tiles, it is essential to tap the tiled mosaic tiles to ensure a tight bond with the substrate, preventing detachment.
2. When installing mosaic tiles, the wall surface must be kept clean and dust-free to prevent the tiles from detaching.
3. When laying mosaic tiles, it is recommended to use cement mortar with uniform and consistent density and humidity. If the density and humidity of the cement mortar are inconsistent, it can easily lead to detachment of the mosaic tiles.
