Selecting the right type of grout is also key for optimum performance. Epoxy grouts offer superior stain resistance and durability, making them ideal for high-traffic areas or environments prone to moisture, such as bathrooms and kitchens.

Cement-based grouts are a more economical option suitable for less demanding applications.

Follow the manufacturer's instructions carefully when mixing the grout. Aim for a smooth, consistent paste-like consistency. Avoid adding too much water, as this can weaken the grout and lead to cracking.

Using a grout float, apply the grout to the tile surface at a 45-degree angle, pressing it firmly into the grout lines. Work in small sections, ensuring that the grout fills each joint completely.

Remove excess grout from the tile surface immediately by holding the float at a 90-degree angle and scraping diagonally across the tiles. Don't worry about getting every last bit – the next step will take care of that.

Cleaning and Initial Shaping: The First Pass

After about 15-30 minutes, or as recommended by the grout manufacturer, begin cleaning the tile surface with a damp grout sponge. Dip the sponge in clean water and wring out the excess, ensuring it's damp but not soaking wet.

Wipe the tiles diagonally to avoid pulling grout out of the joints. Rinse the sponge frequently in clean water to prevent re-depositing grout haze.

Repeat this process several times until the tiles are relatively clean. As you clean, use your finger (wearing a rubber glove) or the edge of the grout sponge to shape the grout lines. Aim for a smooth, slightly concave profile that enhances the appearance and facilitates water runoff.

Final Cleaning and Haze Removal: Polishing to Perfection

Once the grout has dried slightly (usually after a few hours), a haze of grout residue will likely appear on the tile surface. This is normal and easily remedied.

Use a clean, dry cloth or a microfiber towel to buff the tiles, removing the grout haze. If the haze is stubborn, you can use a specialized grout haze remover, following the manufacturer's instructions carefully.

Sealing the New Grout: Protection and Longevity

Sealing is the final, crucial step in the re-grouting process, particularly for cement-based grouts. Grout sealers penetrate the porous grout, creating a protective barrier that resists water, stains, and mildew.

Apply the sealer according to the manufacturer's instructions, typically with a brush or applicator pad. Allow the sealer to dry completely before exposing the grout to water or heavy traffic.

Re-apply grout sealer periodically (every 1-2 years) to maintain optimal protection and extend the life of your grout.
