Sanded or Unsanded Grout for Porcelain Tile: Which One to Choose?

When it comes to tiling projects, choosing the right grout can make all the difference in the final result. Porcelain tile is a popular choice for its durability and low maintenance, but deciding between sanded and unsanded grout can be confusing. In this article, I will discuss the differences between sanded and unsanded grout and which one is best for porcelain tile.

Sanded grout is a cement-based grout that contains fine sand particles, which give it added strength and stability. It is recommended for grout joints that are wider than 1/8 inch, as the sand helps prevent cracking and shrinking. However, sanded grout can scratch delicate surfaces such as glass, metal tile, or polished marble. Unsanded grout, on the other hand, is made without sand and is best suited for grout joints that are less than 1/8 inch wide. It is smoother and easier to work with, but may not be as durable as sanded grout.

When choosing between sanded and unsanded grout for porcelain tile, it is important to consider the size of the grout joints and the type of porcelain tile being used. While sanded grout is generally more durable, it can damage certain types of porcelain tile. Unsanded grout is smoother and less likely to scratch delicate surfaces, but may not be as strong as sanded grout. Ultimately, the decision between sanded and unsanded grout will depend on the specific needs and requirements of your tiling project.

Understanding Grout

Grout is an essential component of any porcelain tile installation. It is a mixture of cement, water, and sand that fills the gaps between tiles, creating a smooth, even surface. Grout also helps to prevent water and dirt from seeping beneath the tiles, which can cause damage over time.

Sanded Grout

Sanded grout contains fine sand particles that help to make the mixture more durable and resistant to cracking. It is typically used for larger grout lines, usually greater than 1/8 inch, and is recommended for tiles that are exposed to heavy foot traffic or moisture. Sanded grout is also ideal for tiles with rough or uneven surfaces, as the sand particles help to fill in any gaps or irregularities in the tile surface.

When using sanded grout, it is essential to ensure that the grout lines are completely filled and that any excess grout is wiped away before it dries. Failure to do so can result in a rough, uneven finish that can be difficult to clean.

Unsanded Grout

Unsanded grout is a smoother mixture that is typically used for smaller grout lines, usually less than 1/8 inch. It is recommended for tiles with a polished or smooth surface, as the lack of sand particles helps to prevent scratching or damage to the tile surface.

When using unsanded grout, it is important to ensure that the grout lines are completely filled, as the lack of sand particles can make the mixture more prone to cracking or shrinking. It is also important to avoid using unsanded grout in areas with high moisture or foot traffic, as it may not be as durable as sanded grout.

Overall, the choice between sanded and unsanded grout depends on the size of the grout lines and the type of tile being installed. By understanding the differences between these two types of grout, you can ensure that your porcelain tile installation is both durable and visually appealing.

Choosing the Right Grout for Porcelain Tile

When it comes to choosing the right grout for porcelain tile, there are a few factors to consider. The two main types of grout are sanded and unsanded, and each has its own advantages and disadvantages. Here are some things to keep in mind when making your decision.

Factors to Consider

  • Tile Size: The size of your porcelain tile will play a role in determining which type of grout to use. Unsanded grout is best for tiles with a narrow grout line, typically less than 1/8 inch wide. Sanded grout is better for larger tiles with wider grout lines.

  • Location: The location of your porcelain tile will also be a factor in your grout decision. If the tile is in an area with high moisture, such as a bathroom or kitchen, unsanded grout is a better choice because it is more resistant to mold growth. Sanded grout is better for high-traffic areas, such as floors or countertops.

  • Color: The color of your grout can also make a difference in the final look of your porcelain tile. Sanded grout is available in a wider range of colors than unsanded grout, so if you’re looking for a specific color, sanded grout may be the way to go.

Grout Size

The size of your grout line will also determine which type of grout to use. Here’s a breakdown of which grout to use based on the size of your grout line:

  • Less than 1/8 inch: Use unsanded grout.
  • 1/8 inch to 1/2 inch: Use sanded grout.
  • Larger than 1/2 inch: Use a special type of grout called “wide-joint” grout.

Overall, choosing the right grout for your porcelain tile can be a bit overwhelming, but by considering factors such as tile size, location, and grout line size, you can make an informed decision.

Application and Maintenance of Grout

Application Process

When it comes to applying grout for porcelain tile, the process is relatively straightforward. First, make sure that the tile has been properly installed and that any excess mortar or adhesive has been removed. Then, mix the grout according to the manufacturer’s instructions, being careful not to add too much water.

Next, spread the grout over the tile using a rubber float, making sure to push it into all the joints. Once the joints are filled, use a damp sponge to wipe away any excess grout from the surface of the tile.

After the grout has had time to dry, usually around 24 hours, use a dry cloth to buff away any remaining haze. It’s important to note that sanded grout is typically used for wider joints, while unsanded grout is used for narrower joints.

Maintenance Tips

Proper maintenance of grout is essential for keeping your porcelain tile looking its best. Here are a few tips to help you keep your grout in top condition:

  • Regularly clean your tile and grout with a mild detergent and warm water. Avoid using harsh chemicals or abrasive cleaners that could damage the grout.

  • If you notice any cracks or gaps in the grout, repair them as soon as possible to prevent water and debris from getting trapped beneath the tile.

  • Consider sealing your grout to help protect it from stains and moisture. Be sure to follow the manufacturer’s instructions carefully and reapply the sealer as needed.

By following these simple application and maintenance tips, you can ensure that your porcelain tile and grout will look great for years to come.
