Old floor tiles on the new tile method

The method of pasting new tiles on old floor tiles includes:

1. Surface treatment: clean up the surface of the old floor tiles, remove dust and oil and other impurities, and sand the surface with a grinder or sandpaper, so that the new tiles can be better adhered.

2. Bottom priming: lay a layer of 1-2cm thick cement mortar on the surface of the old tiles, and scrape the surface with a scraper to make it flat and smooth. Wait for the mortar to dry, use sandpaper to polish the surface.

3. Tile Drawing: Use pencil or charcoal to draw the size of the new tiles that need to be cut, or use a tile cutter to cut out the required size directly.

4. Tile Pasting: Put the new tiles on the old floor tiles, apply the right amount of tile glue, and gently tap the tiles flat with a rubber hammer to make sure that they are firmly pasted. When laying new tiles, care should be taken to leave appropriate gaps to accommodate the expansion and contraction of the ground.

5. Tile fixing: wait until the glue is dry, you can use tile adhesive or cement mortar and other materials to fill the gap, and scrape the surface with a scraper. When the filler is dry, use a rubber mallet and rubber collater to collage the tiles and filler together to make it more solid.

It should be noted that the new tiles on the old floor tiles need to pay attention to the following matters:

1. Collect the dust: clean up the dust and garbage on the ground before laying the new tiles, to avoid the impact on the adhesion of the new tiles.

2. Choose the right glue: you need to choose the right glue for both the old floor tiles and the new tiles to make sure they stick firmly.

3. Control the weight of the tiles: If the new tiles are heavier than the old floor tiles, you need to pay attention to the weight-bearing capacity of the floor to ensure safety.

4. Pay attention to leave gaps: When laying new tiles, you need to pay attention to leave appropriate gaps to accommodate the expansion and contraction of the floor.

It should be noted that if the surface of the old floor tiles is broken or uneven, it needs to be repaired and treated so that the surface is even when laying new tiles. It is also not recommended to lay new tiles on old floor tiles if they are too slippery or worn out. In addition, care should be taken to use safety tools when laying new tiles to avoid injuries or other safety issues.
