How long does it take to grout 400 sq ft

Grouting is essential in completing a tiling project, as it helps fill in the gaps between tiles and provide a seamless, finished look. But how long does it take to grout a 400 sq ft area?

The answer depends on several factors, including the size of the tiles, the thickness of the grout lines, and the speed and efficiency of the person doing the grouting. Generally, it can take several hours to a full day to grout a 400 sq ft area.

Factors That Affect Grouting Time

  • Tile size: Larger tiles generally require less grout, so it will take less time to grout a 400 sq ft area if you’re using large tiles.
  • Grout line thickness: Thicker grout lines will take longer to fill in than thinner ones.
  • Grouting speed: Some people are faster at grouting than others, so the time it takes to grout a 400 sq ft area will vary based on the individual’s skill level and experience.
  • Several grout lines: The more grout lines you have to fill in, the longer it will take to grout the area.
  • Grout type: Different types of grout have different drying times, which can affect the overall time it takes to grout a 400 sq ft area.

Tips for Speeding Up the Grouting Process

  • Use a grout float: A grout float is a tool specifically designed for spreading grout and can make the process faster and easier.
  • Work in small sections: Grouting a large area can be overwhelming, so it’s helpful to break it down into smaller sections and tackle one section at a time.
  • Use a wet sponge: Wiping excess grout with a damp sponge can help speed up the process and give you a cleaner, more professional finish.
  • Use a grout sealer: Applying a grout sealer after grouting can help to speed up the drying time, allowing you to move on to the next step in your tiling project more quickly.


Overall, grouting in a 400 sq ft area can take anywhere from several hours to a full day, depending on the size of the tiles, the thickness of the grout lines, and the speed and efficiency of the person doing the grouting. Following the tips and best practices outlined above can help ensure a smooth, successful grouting project.
