  • May not be suitable for some ceramic, glass, marble, or stone due to the risk of scratching. 
  • Pre-mixed grout lacks the flexibility to adjust consistency as per your liking. Depending on the application, some may find the lack of control over grout consistency to be a drawback.

Sanded vs Unsanded Grout

When installing tiles, sanded and unsanded grout are the two main options for filling the gaps between them. The size of the sand particles contained within the grout is what sets them apart.

Sanded grout is a type of grout that contains fine sand particles. For wider tile joints, it is often recommended to use this material because it offers additional strength and helps prevent the grout from shrinking too much as it dries. 

When it comes to tiling, this grout material is commonly used for floor tiles and larger wall tiles. 

Unsanded grout, on the other hand, does not contain sand particles. With its smooth texture, this type of grout is preferred for narrower tile joints. 

It is also easier to work with, making it perfect for vertical surfaces like walls and mosaic tiles with tight spacing.

How to Choose Grout Color 

Choose Grout Color

Tile Color

Start by examining the color of the tiles you’ll be installing and where it is going. 

Contrasting grout colors can enhance the visual appeal of your tile, but it can also create a cluttered look in a larger space. 

In contrast, by matching the grout to the tile color, a small space can appear more spacious.

Tile Size

Depending on the size of your tiles and the width of the grout joints, you may need to choose lighter or darker grout. 

For a cohesive look, matching the grout color to the tile color is recommended for larger tiles with narrower grout lines. 

However, a contrasting grout color can add personality to smaller tiles with wider grout lines.


What is the aesthetic you’re looking to achieve? 

If you want a clean and modern look for a bathroom, a grout color that closely matches the color of your tile will create a more uniform appearance. 

Opting for a slightly contrasting grout color can add character to your space by highlighting the individual tiles. This can be particularly useful in tiled splashbacks, bathrooms, or feature walls.

How To Match Grout Color

Fill the tile joints with grout

Selecting your grout color isn’t as simple as white or black, as when it comes to grout there are endless options for color and texture combinations depending on what you need! 

Knowing what type of grout to use will help you speed up the process of selecting the right color. Once you’re certain about the type, you’ll need to consider whether you want to:


When the grout color matches and blends with the tile, the focus shifts to the beauty of the tile rather than the lines between each piece. 

To achieve this, select a grout color that closely matches the main color of the tile.


By using different colors for the tile and grout, the eye is drawn to the overall design and layout of the tile. 

This may be the best choice with decorative patterns or if you’re looking to make a more eye-catching design statement. 


Sitting in the middle are your neutral grouts. These versatile and subtle colors come in a wide range of colors from gray to beige and are perfect for any tiling need.

This can suit a wide range of tile colors and styles, and while they are often used in commercial settings such as public bathrooms, they are also ideal in the residential home as well.


Does Epoxy Grout Have Problems?

Whilst epoxy grout is well sought after for its durable and versatile nature, it is well known to be more expensive, harder to apply, and prone to discoloration.

Does Grout Need To Be Sealed?

In short: the answer is yes. To prolong the life of your tiles, it’s crucial to use a sealer – especially in areas with high use and moisture levels. 

Additionally, it’s important to adhere to the manufacturer’s guidelines and reapply the sealer regularly.

How Long For Grout To Dry Before Sealing

As a general rule of thumb, you should wait at least 48 hrs after applying grout before you reach for the sealant.

Are grouts waterproof?

A grout’s water tightness is down to the type it is. 
While they offer some level of water resistance, concrete-based grouts are not completely waterproof. 

On the other hand, epoxy resin-based grouts are known for their high water resistance – making them a popular choice for dual-purpose applications as both a grout and a sealant.
