The answer is yes. The force-bearing area of the big size tiles is very large. It must be ensured that the big size tiles are flat when paving and cannot be different in height. In addition, the big size tiles must be fully combined with the tile glue, otherwise unevenness or hollowing will occur. It is fatal for paving. Lay the tiles evenly on the base layer, and use a vibrator to beat the tiles to make it easy to discharge air bubbles and increase the full grout rate at the bottom of the tiles to avoid hollowing. Use a vibrator to flatten the tile surface and measure it with a level to ensure that the tiles are laid horizontally.
When paving the big size tile, be sure to use a toothed scraper to evenly apply the adhesive on the back of the big size tile, the wall or the ground. Pay attention to scraping the teeth along the short side of the big size tile, also the wall and the big size tile need to be scratched in the same direction to facilitate the air discharge and avoid the problem of falling off caused by the hollowing of the tile glue. One hour after paving, check for empty drums. Knock on the surface of the big size tile. If you hear the "empty" floor tiles, you must try to re-lay them. The caulking construction can be carried out 24 hours after the tiles are laid.

The foundation and wall foundation is the key. First, find the level, so that the tiles are not hollow! If you want to stick the big board firmly, the tile glue is necessary. The tile glue has liquid and solid. The tile glue must be applied evenly on the base layer and the back of the tile. Because tile adhesive is a polymer-modified cement-based interface treatment material, it can improve the bonding strength between the tile and the tile adhesive.
The big size tile is hard to move! If you want to do well, you must choose your tools well! Compared with small size tile, such as 500x500mm, 600x600mm, 800x800mm, 600x1200mm, the big size tiles require special handling and pasting tools. Prepare transport wheels, shifters, transport suction cups and other tools in advance. Use professional tools to transport the slabs to the construction location, or use suction cups and transport rods to transport the big size tile. When moving the big size tile, you can use the moving rack to carry them. It saves effort and time, and it also prevents damage to large slab tiles.
