Grouting Tools

Essential Grouting Tools for Tile Work

Grout secures and holds a tile installation in place and prevents water from entering the joints. After decades of stocking job sites around the world, we’ve learned that the right grout tool for tile work makes the real difference between a clean finish and a redo.

The essential elements of a basic grouting kit include the following:

• a grout float for applying the material to the joints

• a bucket for mixing and rinsing

• sponges for cleaning up

• a grout bag for tight or vertical spaces.

For most residential and commercial projects, add a margin float to edges and corners, and you're set.

Types of Grouting Tools Explained

There are two main styles of grout floats. Rubber floats are best suited for sanded grout and the standard joint width. Sponge floats will not scratch glazed tile when working with epoxy and unsanded grout. One of the most common mistakes is selecting the wrong float for the grout being used. Typically, it results in the tile or grout being scratched or the grout not sitting flat in the joint.

Sponges are more important than most realize. When the grout is removed from the joint by a stiff, poor-quality sponge, it does not smooth the joint. Hydra sponges and Raimondi replacement pads evenly hold water and rinse clean, ensuring that you have consistent joint lines throughout the tile installation. A special grout finishing tool provides the control you need to shape corners and transitions without smearing adjacent surfaces for epoxy grout.

Complete the setup with a bucket. Use a two-bucket system with one bucket for clean water and one for rinsing. This will prevent any buildup of haze on your tile and prolong the life of your sponges. Wash systems such as the Raimondi Pedalo go one step further with foot-pedal rinsing to make larger jobs easier to clean.

How to Use Grounding Tools

Grout should be applied at a 45-degree angle to the joint. It should be pushed firmly so that the float can pack the material into the joint. Grout in small sections, about 3-4 square feet at a time; this prevents the grout from drying before it is cleaned.

As the surface begins to haze (typically within 15-20 minutes after application, depending on humidity), use your sponge and wipe diagonally across the joints in a figure-eight pattern. This prevents you from pulling the grout back out of the lines that you have just filled.

Wash your sponge frequently. A saturated sponge simply transfers haze, but does not remove it. Replace rinse water in several sections and buff with a dry cloth after the haze has disappeared.

Tips for Clean and Professional Results

New to grouting? Use a rubber float and a two-bucket system first. Then progress to epoxy work, which dries quicker and forgives fewer mistakes. Clean tools between uses. Rinse off floats and sponges after every use, and allow them to air-dry thoroughly before storage. If you have dried grout residue on a float edge, it will scratch the surface of your next tile, and a hard sponge will not evenly absorb water.

Don't mix grout too wet. Do not work on too large sections. Avoid letting grout sit outside of its working time before cleaning up. All of these result in uneven color, weak joints, or a haze that will take hours to remove.
