Three Types of Grout Used for Tile Installations

Three Types of Grout Used for Tile Installations

Every type of ceramic tile makes use of a grout that is used to fill in and seal the joints between tiles. No matter if the tile is traditional ceramic, porcelain, quarry tile, or even natural stone, it is essential that the seams between tiles are properly filled with a substance that stops water from getting underneath. To ensure that the tile is water-proof all grouts need to be maintained properly, repaired whenever cracks develop, and regularly sealed to ensure that the grout remains fully waterproof.

There are three kinds of grout: cementitious grouts consisting of a Portland cement foundation; epoxy grouts, as well as the furan type, and there, are variations in each. The epoxy and cementitious grouts come in a variety of shades that let you blend and contrast with the colors of tiles. Furan grouts are generally available in black.

Cementitious Grouts

Cementitious grouts contain as their principal ingredient Portland cement, as well as filler particles in various sizes, a water-retentive ingredient as well as colored pigments. Cementitious grouts are the most common grouting material used frequently in residential and also in commercial applications. Cementitious grouts are available in a variety of shades that allow you to blend or make a contrast with the tile. This grout is mixed with water and then applied using the help of a trowel. The water-retentive component in cementitious grouts slows down the drying time, which allows the cement to cure slowly to ensure maximum strength.

If used with porous tiles, such as slate, quarry, or any other naturally-occurring stone tiles cementitious grout may be stained by the surfaces. The majority of professionals seal the tiles prior to grouting. This step isn’t necessary for regular glazed tiles.

Sanded against. Sanded vs.

Sanded cementitious grouts contain large sand particles which can be felt and seen. They are both textured and look. Sanded grout is typically advised when grout seams are 1/8 inches large or larger, as the sand gives a stronger bonding strength that stops cracks from occurring. Certain care should be taken when using sanded grouts on polished tiles since the sand could scratch the tiles. A test of the grout on a sample of tiles is an excellent idea.

Unsanded grouts are a much easier texture due to the fact that the mineral particles that they hold are very fine powders and don’t have any apparent grit. They are typically used for grout seams of 1/16 to 1/8 inches wide. If used in conjunction with larger seams, grouts made of unsanded materials are more likely to crack due to the lack of the strength of binding provided by the sanded grouts.

Latex Modified Grout

Sanded grouts can be made using a latex polymer additive, which can be included within the dry mixture, or added when the grout mix with water. The additive increases the water-proofing capabilities of the grout and increases its strength.


Cementitious grouts are the most sought-after and can be utilized virtually anywhere tile is used. However, grouts that contain additives made of latex are a bit porous and prone to staining. The grouts of all cementitious types must be sealed with a penetrating sealer once a year or so to ensure that they remain free of staining and completely waterproof.

Epoxy Grouts

Epoxy grouts are a completely different type of grout, and do not require Portland cement. There is no water during the mix-up. These grouts comprise silica fillers as well as pigments and an emulsifier. Epoxy grouts are significantly more porous than cementitious grouts and can be a great choice in areas where greases and acids are prevalent, such as kitchens.

Epoxy grouts are available in unsanded and sanded versions but the kind of sand used in these groups is different from the cementitious grouts. Epoxy grouts can be set up quite quickly, which makes them somewhat difficult for novices. The grouts made of epoxy are more expensive, at around $8 per pound as opposed to. $1-$2 for cementitious grout. For areas where stain resistance is needed, epoxy grout is the best option.

It is important to be aware of the fact that grout made with epoxy may severely stain tiles with nonglazed and porous like granite or stone tiles. If you use epoxy grout to grout these tiles they must be sealed prior to grouting.


The advantage of epoxy grouts is they do not require sealing, like cementitious grouts. However, they may become stained. Scrubbing them with a mix of bleach and water also vinegar is a common method to clean epoxy grout.

Modified Epoxy Epoxy Modified

A different type called hybrid grout is available and is basically an epoxy grout enriched by Portland cement. The features that this type of grout has are comparable to regular Portland cement grouts. They have to be sealed regularly, for example. However, these groups are stronger, harder, and stain-resistant than regular cementitious grouts.

Furan Resin Grouts

Furan grout is similar in structure to epoxy however, it is composed of alcohol-based polymers which are extremely chemical-resistant. The name is derived of the Furfuryl alcohol in the formulation. There isn’t any water used in this kind of grout. Furans are two-component structures that include the resin of furan and the filler powder, which has the acid catalyst. It is the catalyst for acid responsible for causing the resin to cure, creating an extremely thermosetting resin with unparalleled physical, chemical resistance, and thermal properties.

Furan grout is typically utilized to cement brick pavers as well as quarry tiles and it is recommended for areas that are exposed to grease and chemicals. The tile’s surfaces can appear smooth or non-skid or abrasive depending on the intended usage for flooring. The brick or tile surfaces require a wax-coated coating to guard them against staining prior to the installation of the furan. Due to the difficulties of installation, they are usually utilized for industrial projects like dairies, laboratories, and meatpacking plants.

Be aware of the precautions to take before mixing to prevent getting vapors into your lungs. Specific expertise is required for correct installation. This should be performed when and utilized when temperatures are between 60 to 90°F (70 between 70 and 80 is the ideal temperature).

Installation Cost

Cost is contingent on the degree of experience of the contractor as well as the location in which the grout tiles will be put. On average it is safe to estimate that the price could vary from $3 and 5 dollars for each square foot of grouting, cleaning, and sealing (where necessary).
