1, In general, tile grout can be remade. However, before you do that, the color of tile grout needs to be chosen and the original grout must be removed. Dust and residue of the old grout should all be cleaned up from the tile gap. Make sure the gap of tile is clean and dry before construction of new grout.

2, You need to use a small shovel knife to cut along the position of old grout if you want to clean up that, and then seize one end of the grout after cutting so that you can tear off the old grout.

3, When most of the grout has been torn off, you also need to use suck the dust, debris, etc in tile gap with a vacuum cleaner. Afterwards, use a wet cloth to wipe the tile gap. Make sure the cloth is only wet without dripping water.

4. New grouting can be started after tile gap is fully cleaned and dry. Construction methods for regrouting is the same as that for the first grouting. The only difference is the tile gap cleaning. It must be checked carefully since the grout cannot be unified together with tiles if tile gap is not clean.
