When the tile grout is not popular, many families choose to use white cement mortar to fill the tile gap after tiling. However, over time, the white cement in the gap will appear to fall off, yellowing and black problems, which not only affects the beauty, but becomes difficult to clean. Also, the hidden dirt in the gap will affect health.

So, the tile grouting is often done together with a lot of old house renovation. After all, the newly grouted tiles look brand new.

The biggest difference between the old house and the new house is actually the gap cleaning. After tile gaps are cleaned up, the remaining steps of tile grouting is the same as the new house tile grouting. The old house was originally caulked with white cement. Although some have fallen off, the task of cleaning the gap is still not easy, so the following points need to be followed when cleaning the gap.

1, The tile gap is too dirty.

After being used for years, the tile gaps have been filled with a variety of dust particles, and tile gaps around are black, bringing a lot of difficulty to the cleaning of gaps, so we must be more serious to clean up the gaps. The sand inside the cement should also be cleaned out. After the gaps are cleaned up, use a vacuum cleaner to suck away all the floating dust, and then wipe the tile surface with a rag.

2, Tile wear degree

After being used for a long time use, the tile surface may appear a lot of wear and tear, especially on glazed and polished tiles. If the tiles are worn seriously, it is recommended to use the masking tape when doing grouting, so that the spatula can avoid touching with the worn surface when cleaning up the residual.

3, Tile solidity

Tiles in old houses lived for many years are inevitably loose, bulging , etc, so carefully check every tile in your home before the grouting construction. Loose tiles will affect the bonding degree of the tile grout, so that the grouted area is not firm, affecting the grout effect. If you find loose tiles, be sure to re-fix, and then do the grouting to avoid future problems.

4, Whether the gap of tiles is wet.

After years of use, daily cleaning, mopping and etc, tile water will inevitably seep into the gap. Before doing grouting, be sure to keep the tile gaps dry, especially the bathroom. In addition, before the grout cures, please also keep it dry and avoid stepping on.
