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. **

The Specialized Roubaix SL4 is not suitable for forest trails or hiking trails. It is a road bike designed for smooth pavement and is not equipped to handle the rough terrain and obstacles typically found on trails. Using this bike on forest or hiking trails could potentially damage the bike and compromise safety. It is recommended to use a mountain bike or a hybrid bike with more robust tires and suspension for off-road trails. **

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. **

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. **

Customers may need to arrange for grouting separately or inquire with the installation service provider for additional costs. **
