How To Use A Grout Float
05/08/2025If you're tackling a tiling project, understanding how to use a grout float is essential for achieving a flawless finish. In this guide, we’ll break down everything you need to know about grout floats, from their purpose to the different types available, and how to use them correctly.
What Is a Grout Float?
A grout float is a grouting tool used to apply tile grout into the spaces between tiles. It has a flat surface, typically made from rubber, and a handle that allows you to press and spread grout smoothly over the tiled surface. The rubber base is firm yet flexible, which helps press the grout into the joints without damaging the tile.
Do You Need a Grout Float?
If you’re grouting tiles, you need a grout float to ensure the grout is packed properly and evenly. Skipping this tool often results in air gaps, uneven coverage, and a poor finish. Using the correct tiling tools saves time and avoids costly mistakes.
Can You Grout Without a Float?
Technically, yes, but it’s not recommended, and certainly not if you want a high-quality, lasting finish. Some people try to use tools like putty knives, credit cards, or even their hands, but the results are usually subpar. The right float for grouting ensures consistent pressure, reduces mess, and makes it easier to clean excess grout off the tiles.
What Type of Grout Float To Use
When choosing what type of grout float to use, consider the type of tile and the grout being applied. Here are some top grout float choices:

Step-by-Step Guide: How To Use A Grout Float
Here’s a simple guide to show you how to use a grout float properly:
Step 1: Mix the tile grout
Follow the manufacturer’s instructions to mix your tile grout. You may need a paddle mixer or mixing bucket.
Step 2: Load the grout float
Scoop a generous amount of grout onto your grout float. Hold the float at a 45-degree angle and press the grout into the tile joints.
Step 3: Spread the Grout
Using diagonal strokes, work the grout across the tiles to fill all joints. Avoid pressing the float directly in line with the joints, as this can pull grout out.
Step 4: Remove Excess Grout
Hold the float almost upright (about 90 degrees) and scrape off excess grout from the tile surface, moving diagonally to avoid dislodging grout from the joints.
Step 5: Clean the Surface
After 15–30 minutes (depending on grout type), use a damp grout sponge to wipe off any grout haze. Don’t use too much water, as excess moisture can weaken the grout.
Tips for Success When Using A Grout Float
Choose the best grout float for your specific tile type, tile grout, and project size.
Always work in small sections so the grout doesn’t dry out before you finish cleaning.
Clean your grouting float regularly during use to prevent hardened grout from affecting your finish.
For porcelain and polished tiles, it’s best to use a rubber grout float with a dense, firm base. In fact, the best grout float for porcelain tile is typically a rubber grout float with rounded corners, which can apply consistent pressure without scratching the surface. A good example would be the Raimondi Soft Rubber Interchangeable Grout Float.
When working with epoxy grout, you’ll want to make sure you’re using a suitable grout float, such as the Kubala Plastic Handled Epoxy Grout Float, Genesis Duel Edge Hard Rubber Eco Grout Float, Vitrex Maxi-Flex Grout Float, or Rubi Epoxy Grout Float.
