Many homeowners, eager to move in, overlook the timing for grout sealing and rush through the process, resulting in issues. This is quite normal, as grout sealing requires careful timing, and the combination of "favorable conditions, suitable environment, and proper execution" is essential.

Timing for grout sealing is crucial and should be considered as follows:

1. 7-10 Days After Tiling:

   After the tiles are installed, the cement mortar in the gaps needs about a week to fully dry. Grout sealing should be done afterward to ensure it does not affect the adhesion of the grout.

2. Before Painting:

   Painting can generate dust and debris, which may fall into the gaps. Since grout sealing requires the gaps to be cleaned, this dust can complicate the process.

3. Before Wallpapering:

   The process of applying and removing wallpaper can create dust. If this dust mixes with the air and enters the gaps, it can affect the adhesion of the grout and lead to issues like black edges later on.

4. Before Ceiling Installation:

   Installing a ceiling can cover some of the gaps, making it difficult for the grout technician to inject the sealant properly. This can result in missed areas and affect the overall appearance and integrity.

5. Before Carpentry Work:

   Carpentry can generate wood shavings, which are often very fine and can easily fall into the gaps. This makes cleaning the gaps more difficult.

6. Before Moving Furniture:

   Furniture is usually placed after other work is done. Moving furniture first can affect not only the grout sealing process but also other aspects of the renovation. It can obstruct areas and make it challenging for the grout technician to complete their work.

Considerations for the Work Environment:

1. Keep the Area Dry:

   Maintain a dry environment during the grout sealing process. If humidity is high, use heating tools to reduce it.

2. Avoid Water Use:

   Do not use water before or during the grout sealing process.
