If you're planning on installing new tile flooring, it's important to choose the right grout to ensure the longevity and overall look of your project. With so many options available, it can be overwhelming to know which one to choose. In this article, we'll break down the key factors to consider when selecting the right grout for your tile flooring.
Understand the Types of Grout
There are three main types of grout: cement-based, epoxy-based, and furan-based. Cement-based grout is the most common and affordable option. It's easy to work with, and it's available in both sanded and unsanded varieties. Epoxy-based grout is more expensive but has the benefit of being more durable and stain-resistant. Furan-based grout is the most expensive option and is primarily used in industrial applications due to its resistance to harsh chemicals and extreme temperatures. 
Consider the Material and Size of Your Tiles
The type of grout you choose will depend on the material and size of your tiles. Smooth or glossy tiles, such as ceramic or glass, require fine powder grout for narrow joints (1-4mm). Coarse grout is better suited for larger joints, such as those found in natural stone tiles. 
Determine the Final Use of the Tile Installation
Consider the final use of your tile installation. In high-traffic areas, such as shopping malls or leisure complexes, choose a grout that can cope with the increased demands placed on the flooring. Heavy-duty floor tile applications require grout that is able to withstand more stress. 
Choose the Right Grout Color
Selecting the right grout colour is just as important as selecting the right type of grout. Consider the colour and style of your tiles, and choose a grout colour that complements them. For example, if you want your tiles to stand out, but not as much as they would with a contrasting grout colour, go with a neutral grout tone. If you're contrasting colours, make sure to pick colours that complement each other.  When matching the grout colour to the tile, consider selecting the same colour grout as the tile to avoid visible grout lines. This approach works well with bold or understated tiles that have extravagant veining, textured finishes, or attention-grabbing colours. 
Sealing Your Grout
After selecting your grout, consider sealing it to protect it from stains, mould, and mildew. Follow the manufacturer's instructions for mixing and applying the grout. Improper mixing can lead to uneven colour pigment distribution, which can cause splotchy and inconsistently-coloured grout lines. 
Here are some additional tips to keep in mind when selecting grout for your tile flooring:
- If you're using joints that are less than 1/8" thick, it's best to use unsanded grout. If you're using joints that are 1/8" thick or wider, sanded grout will be your best choice as it'll hold your tiles together better and help
- against cracking. 
- Install tile on a piece of plywood with different grout colours, then take it into your room to see how the lighting affects the colours. Note that grout can take several days to fully cure, so give it enough time to cure before making a final judgement. 
In conclusion, choosing the right grout for your tile flooring is crucial to the overall look and longevity of your project. Consider the type of grout, the material and size of your tiles, the final use of the tile installation, and the colour of the grout to make the best decision for your space. Don't forget to seal your grout properly and follow the manufacturer's instructions for mixing and applying it.
