What is the best way to backfill the bathroom?

Toilet backfill refers to filling the gaps between tiles after the tiles are laid in the bathroom. The following are the common methods of toilet backfill:

1. Cleaning preparation: Before backfilling, ensure that the bathroom floor is clean and flat, and remove any sundries and residues.

2. Choose caulking materials: choose caulking materials suitable for the bathroom environment, usually waterproof, wear-resistant and mildew-proof caulking agents. Choose the right color as needed.

3. Joint filling: Use a joint filling scraper or a joint filling gun to evenly squeeze the joint filling agent into the gap of the ceramic tile. Ensure that the joint filler fills the gap and is flush with the tile surface.

4. Smoothing: Scrape off the excess caulking agent with a caulking scraper or a wet sponge to ensure that the caulking agent and the surface of the ceramic tile are flat. Avoid splashing caulking agent on the surface of ceramic tile.

5. Wipe clean: After the caulking agent is completely dried, wipe the surface of the ceramic tile with a wet cloth or sponge to remove excess caulking agent.

6. Waterproof treatment: After backfilling, if it is necessary to further strengthen the waterproof performance, you can apply waterproof paint or waterproof glue to ensure the waterproof effect of the bathroom floor.

Please note that toilet backfilling is a meticulous work, which requires patient and meticulous operation. If you are unfamiliar with the operation or lack of experience, it is recommended to invite professionals to carry out the construction to ensure the quality and effect of backfilling.
