Achieving white joints in just 10 minutes after grouting is a desired outcome for many tilers. While there is no magical secret to accomplish this, there are a few techniques and tips that can help speed up the process. Here’s what tilers often do to achieve white joints in a relatively short time:

1. Use a rapid-setting grout: Opt for a rapid-setting grout that is specifically designed to cure and dry quickly. These types of grouts are formulated to harden faster than regular grouts, allowing for quicker drying time.

2. Work in small sections: Divide the tiled area into smaller sections and work on one section at a time. This allows you to focus on grouting and cleaning a smaller area before the grout starts to set.

3. Mix grout in small batches: Mix the grout in small batches that you can handle and apply within a short period. This prevents the grout from prematurely drying out before you can finish applying it.

4. Apply the grout efficiently: Use a grout float or a grout bag to apply the grout evenly and quickly into the joints. Ensure that the joints are completely filled, but avoid excessive grout on the tile surfaces.

5. Clean as you go: Immediately after applying the grout to a small section, use a damp sponge or a grout float to remove excess grout from the tile surfaces and smooth the joints. Rinse the sponge frequently to keep it clean and effective.
