Grouting should be done after the tile adhesive has set and the tiles are firmly in place. This typically takes about 24-72 hours, depending on the type of adhesive used. It is important to wait until the adhesive has fully cured to ensure that the grout will adhere properly and provide a strong, durable finish. Additionally, grouting should be done when the weather conditions are suitable, as extreme temperatures or humidity can affect the grout's performance. **

Cement mortar with a mix ratio of 1:3 (1 part cement and 3 parts sand) is commonly used for tile grouting. This type of mortar is suitable for filling the gaps between tiles and providing a strong, durable bond. It is important to ensure that the mortar is mixed to the correct consistency and applied properly to achieve a smooth and even grout finish. **

If the mortar dries on the tile while grouting, you can try using a damp sponge to gently wipe away the dried mortar. Be careful not to apply too much pressure as you may scratch the tile surface. If the mortar is stubborn and does not come off easily, you can try using a commercial grout haze remover following the manufacturer's instructions. It's important to act quickly before the mortar fully sets to make the cleaning process easier. **

The drying time of the tile adhesive must be waited for before grouting because grouting too soon can disrupt the bond between the tiles and the adhesive. If grouting is done before the adhesive is fully dry, it can lead to the tiles shifting or becoming loose over time. Allowing the adhesive to fully dry ensures a strong and durable bond between the tiles and the substrate, resulting in a long-lasting and stable tile installation. **

Grouting is typically not included in the fixed price after the installation of doors. Grouting is a separate process that involves filling the gaps between tiles or other materials, and it is not directly related to the installation of doors. Therefore, it is usually not included in the fixed price for door installation. Customers may need to arrange for grouting separately or inquire with the installation service provider for additional costs. **

At the first coin-operated vending machine, which was created in the early 1880s by Percival Everett, customers could purchase postcards for their money. The machine was installed in the railway stations and post offices in London, and for a penny, customers could receive a postcard featuring a picture of the surrounding area. This early vending machine was a novelty at the time and provided customers with a convenient way to purchase postcards without the need for human interaction. **

It is recommended to wait at least 24 hours after the tiles have been laid before starting the grouting process. This allows the adhesive to fully set and the tiles to stabilize, ensuring a strong and durable bond. Waiting longer, such as 48 hours, may be necessary in humid or cold conditions to ensure the adhesive has fully cured. It is important to follow the specific instructions provided by the adhesive and grout manufacturers for the best results. **
