Is a grout float necessary?

When it comes to grouting tile, one of the most common questions that arises is whether or not a grout float is a necessary tool. A grout float is a trowel-like tool with a rubber or plastic edge used to spread and work grout into the joints between tiles. But is it an essential piece of equipment or can you get by without one? Here’s a look at the pros and cons of using a grout float and whether or not it’s truly necessary.

What is a grout float used for?

A grout float has a few key purposes when grouting tile:

  • Spreading grout – The broad flat surface and flexible edge allow you to scoop up grout and spread it evenly over the tile surface to fill joints.
  • Working grout into joints – By holding the float at a 45-degree angle, you can work the grout deeply into the joints between tiles.
  • Smoothing the surface – Angling the float allows you to skim off excess grout and smooth out uneven areas for a consistent finished look.

So in short, a grout float allows you to fully fill joints, evenly spread grout, and smooth the surface in one tool. The main benefit is being able to work grout thoroughly into joints for a secure installation. It also prevents uneven or pitted areas by smoothing the surface.

Can you grout tile without a grout float?

While a grout float makes the job easier, it is possible to grout tiles without one. Here are some alternate tools and techniques:

  • Sponge – A damp sponge can be used to spread grout. However, it may be more difficult to fully pack joints.
  • Squeegee – Scraping grout over the surface with a squeegee or cardboard works to fill joints. But you lose the smoothing action.
  • Fingers – Pressing grout into crevices with your fingers is effective for small jobs. For larger tile jobs it can be tedious.
  • Wooden dowel – A rounded wood stick can tamp grout into corners. But it does not smooth or flatten the surface well.

While all of these methods can technically get the grout into joints, the finish and quality may suffer without the ability of a float to really pack and smooth the grout. The work will also likely take longer without a proper spreading and smoothing tool.

Pros of using a grout float

Here are some of the main benefits of using a grout float vs. other DIY methods:

  • Faster grouting – The broad surface area and flexibility allow you to quickly scoop up grout and smooth it over tile.
  • Packs joints – The angled edge lets you work grout deeply into crevices for a secure fill.
  • Creates a smooth finish – The float skims off excess grout and levels out uneven areas for consistency.
  • Prevents low spots – All areas get flattened for an even appearance without dips or pits.
  • Neater job – Smoothing action limits mess and reduces cleanup compared to dingers or sponges.
  • Easier on the body – Large surface requires less repetitive motion than fingers or small tools.

In summary, a grout float simply makes the process faster, cleaner, and easier while enabling a pro-quality packed and smooth finish.

Cons of skipping the grout float

Attempting to grout without a proper float can lead to the following issues:

  • Incomplete joint filling – Other tools may not fully pack grout into corners and crevices.
  • Weak spots – Gaps or pores in the grout can compromise the installation over time.
  • Pitted appearance – Without smoothing, grout can dry with dips and uneven areas.
  • Longer time – Fingers or small tools take much longer to spread grout over large areas.
  • Messier process – No smoothing leads to more spills, drips, and needed cleanup.
  • Difficult to fix issues – Once grout dries, low spots and pits become more challenging to remedy.

Taking shortcuts with grouting increases the chances of problem areas, callbacks to make repairs, and a subpar finished look. The small upfront investment in a quality grout float typically pays off in much easier application and better results.

What to look for in a grout float

If you decide to use a grout float, here are key features to look for:

  • Size – A float between 4-8 inches is optimal for balancing portability and joint coverage.
  • Shape – A rounded rectangular shape allows smoother spreading motions.
  • Flexibility – Some give in the edge lets you work grout into crevices more effectively.
  • Durability – Commercial-grade plastic or rubber lasts longer than cheap foam options.
  • Grip – Look for an easy-grip handle for less hand fatigue during prolonged use.
  • Angle – Around a 45-degree bevel enables easier edge work in joints.

Higher priced floats made from materials like vulcanized rubber offer durability and flexibility for the best performance. But less expensive plastic or wood versions still work adequately for DIY home use.

Pro tips for using a grout float

Follow these tips to make the most of your grout float for flawless results:

  • Angle the float diagonally and use light pressure to squeeze grout deeply into joints. Avoid just dragging flat across the surface.
  • Work in small sections so grout stays wet and pliable as you smooth.
  • Hold the float nearly perpendicular and use an oscillating motion to scrape off excess grout.
  • Wipe diagonally across ridges to prevent pulling out grout of joints.
  • Rinse the float frequently so it glides smoothly without dragging.
  • Check for low spots as you work and go back to touch up before grout fully dries.
  • Avoid cheap foam floats which can flex unevenly and leave pits.

With some practice and these tips, a quality grout float makes achieving smooth professional looking joints much simpler.

Conclusion

When weighing the pros and cons, a grout float is an indispensable tool for grouting tile effectively. The main benefits of speed, joint packing ability, smoothness, and convenience make a dedicated float well worth the minor investment. Attempting to grout tile without a quality float is likely to result in a subpar job with potentially uneven or weak joints. This can lead to expensive repairs down the road. Following proper technique with a good grout float minimizes mistakes and provides beautiful flawless grout lines with minimal hassle. For most tile jobs, skipping the grout float is more trouble than it’s worth.
