There are many types of grout available. You may be wondering which type is best for your project. Read on to learn more about Unsanded, Epoxy, and Furan grout. The right choice is critical to the look and longevity of your tiled floor. Whether installing new tiles or simply redoing an existing floor, proper grout will make a huge difference.

Unsanded grout

Sanded grout is recommended for most tile installations, as it has more mixed color options and is more widely available. It also reduces shrinkage. On the other hand, unsanded grout is less popular and only necessary in certain areas. It also does not hold up as structurally as sanded grout.

Sanded grout is preferred when the grout joint is at least 5/8″ wide. Unsanded grout is not recommended for smaller grout joints because too much sand will be present, and the grout may not be able to fill the gap. When using unsanded grout, make sure to fill the grout joints before you apply a sealer thoroughly.

Unsanded grout is less likely to attract dirt, soap scum, and food particles. It is best suited for vertical surfaces. The grout will reach full curing within 28 days. Unsanded grout may be a better choice if you do not plan to walk on the tiled area.

Unsanded grout is ideal for grout lines that are 1/8-inch to half-inch wide. Any wider than this will result in grout lines that slump and crack. Unsanded grout will not compact and therefore have an uneven look. Those with less experience can benefit from the unsanded grout.

When using unsanded grout for tile installation, ensure the joints are under 1/8-inch wide. Unsanded grout does not contain silica aggregate filler. It is ideal for vertical surfaces because of its smooth texture and higher adhesion.

Unsanded grout tends to be lighter than sanded grout. It is because the water used to clean the grout removes colored pigments. Nevertheless, it is still possible to choose grout colors that are a shade or two darker than the color chart.

Unsanded grout is more flexible than sanded grout. It can also be more easily worked into small grout lines. However, it is more expensive and does not hold together as well as sanded grout. It is also more resistant to scratch, which makes it preferable for vertical surfaces.

Furan grout

Furan grout is a thermosetting resin that offers excellent chemical, thermal, and physical resistance. This grout is commonly used in industrial applications such as breweries, laboratories, and institutional kitchens. However, because of its strength, it requires special care and expertise in installation. As a result, it is generally reserved for industrial and commercial projects. Experienced tile installers should only attempt its use.

Furan grout is used for grouting brick pavers and quarry tiles. It is also suitable for areas exposed to grease and chemicals. Furan grout is also resistant to wear and scratching. This grout can be applied to various surfaces, including non-skid and abrasive ones. Furan grout is very difficult to install and requires special skills. You should avoid using it on polished surfaces like granite or marble.

Furan grout is similar to epoxy but is made from polymers containing fortified alcohol. Its name comes from furfuryl alcohol, which contributes to its chemical resistance. It has a two-component structure consisting of a furan resin and filler powder mixed with an acid catalyst to cure. The mixture then forms a tough, thermosetting resin that resists heat and chemicals.

Cementitious, epoxy, and furan grouts are commonly used in tile installations and can come in various colors. They contain Portland cement, filler particles of various sizes, and a water-retentive additive. These types of grouts can be used for both residential and commercial applications. When choosing a type of grout, it is important to know how to properly maintain it to ensure that it stays in perfect condition for years to come.

The best time to apply tile grout from Bostik is when temperatures are between 60 to 90 degrees Fahrenheit. It allows the grout to be set properly. Generally, it would help if you aimed for medium grey colors to avoid staining, but bright colors or bold colors will often change the overall look of the installation. However, if you choose a bold color, be aware that it will show dirt and stains more easily than a medium color.

Another type of grout for tile installation is sanded grout. This grout contains Portland cement but without any sand. This grout is ideal for thin grout lines and is easy to apply to walls. However, it will tend to crack over time. It is also more expensive than sanded grout and is generally used in applications where the grout joints are less than an eighth of an inch wide.

The most commonly used grout is sanded cementitious grout. It is a versatile product and the best choice for smaller grout gaps than 1/8 of an inch. However, it is important to remember that this grout contains a cement base, which will scratch a highly polished tile.
