The floor tiles of the bathroom were broken a few pieces, and I wanted to replace the two rows that

Replace which piece is broken, although it is more troublesome, but the bricklayer can do it.

But there is a premise, you had better match the same model and the same color of the brick, otherwise there will be color difference, affecting the appearance.

If you can't match the bricks of the same model and color, and you have requirements for the effect, you can only replace them all.

Now the floor tiles are basically dry paved, and the normal construction operation will not destroy the waterproof layer.

It's perfectly fine to replace the two rows that were broken and re-lay them. It is recommended to use a manual cutter to cut along the edge of the broken bricks so as not to destroy the good floor tiles around it. Then remove the broken brick garbage and do a good job of waterproofing, and finally pave the floor tiles.

It can be replaced, but there are a few points to pay attention to when playing porcelain tiles: 1. Cut into small pieces with a cutting machine, so as to prevent the expansion of the installation area and not affect the porcelain tiles next to it. 2. When playing porcelain, there should be a trend chart of water and electricity, because there may be water pipes, wires, gas pipes or something under the porcelain tiles, and this is very serious if it is broken.

3. For the problem of waterproofing, after hitting the porcelain tiles, brush them several times to be waterproof.

Yes, remove the broken tiles slowly and lightly, and do not damage the lower waterproofing layer.

If there is damage, repair the waterproof layer, test the water, and restore the tile again without any problem.

You don't need to change the entire floor.

It won't leak.
