Types of grouts. When to Use Cement, Epoxy, and Furan Grouts?
Grout of some kind is used to fill and seal the spaces between ceramic tiles. The joints between the tiles must be adequately sealed with a substance that keeps moisture from penetrating the screed, regardless of whether the tile is made of natural stone, quarry stone, or conventional ceramic. All grouts must be carefully maintained to preserve this waterproofing; cracks must be filled as soon as they arise, and grout must be sealed regularly to guarantee that it is truly waterproof.
Grout comes in three primary varieties: cement grouts, which are derived from Portland cement; epoxy; and furan grouts, each of which has several varieties. The colors of cement and epoxy grouts can be chosen to complement or contrast with the tiles’ color; furan grouts are often only offered in black.
Types of grouts. Cement-Based Grouts
Portland cement is the primary component of cementitious grouts, which also contain colorful pigments, a water-retaining additive, and filler particles of varying sizes. The conventional grouting material that is most frequently used in residential and certain commercial applications is cementitious grout. There are numerous shades of cementitious grouts available to complement or contrast with your tile. Using a trowel, the grout is applied after being combined with water. Cementitious grouts’ water-retaining ingredient slows down the drying process so that the cement can gradually cure and harden to its greatest degree.
Cementitious grout can leave stains on surfaces when used with porous tiles like slate, quarry, or other natural stone tiles. While conventional glazed tiles do not require sealing before grouting, most professionals do so for porous tiles.
Types of grouts. Comparing sanded and unhanded surfaces
Sanded cement grouts have a somewhat gritty appearance and feel due to the presence of noticeable, big sand particles. When the joints are 1/8 inch or wider, sanded grout is typically advised because it adds greater bonding strength to the grout, preventing cracking. Sanded grouts can harm highly polished tiles, therefore proceed with caution when using them. Testing the grout on a sample tile is a smart idea.
The consistency of unhanded grouts is significantly smoother due to the very tiny powdered mineral particles that lack any discernible grit. They work with joints that range in width from 1/16 to 1/8 inch. Unhanded grouts lack the bonding power of sanded grouts, hence they break easily when utilized in broader joints.
Types of grouts. Grout with latex modifications
A latex polymer addition can be added to sandblasted grout mixtures during the water-mixing process or added to the dry mix. The grout’s strength and water resistance are both increased by the addition.
Types of grouts. Upkeep
Cement grouts are the most widely utilized because they may be used practically anyplace tiles are set. Even grouts with latex additives, nevertheless, have considerable porosity and can discolor easily. To maintain complete waterproofing and stain resistance, penetrating sealers should be applied to all cement grouts every year or two.
Types of grouts. Grouts made of epoxy
Without the usage of Portland cement, epoxy grouts take on an entirely other form. Moreover, no water is added during the mixing procedure. These grouts are made up of colors, hardener, silica fillers, and epoxy resin. Because epoxy grouts are significantly less porous than cement grouts, they are a good option for locations like kitchens where acids and grease are common.
Both sanded and unhanded versions of epoxy grouts are available, however the sand type utilized in epoxy grouts is distinct from that of cement grouts. Epoxy grouts can be a little challenging for beginners because they set really quickly. Additionally, epoxy grouts are significantly more expensive than cement grouts, ranging from $1 to $2 per pound to about $8. But epoxy grout might be an excellent option in places where the greatest stain protection is required.
Be advised that porous and unglazed tile surfaces, such limestone or stone tile, can become severely stained by epoxy grout. Tiles should be sealed before grouting if epoxy grout is going to be used on them.
Types of grouts. Upkeep
Unlike cement grouts, epoxy grouts have the benefit of not requiring sealing. They may, however, get discolored. For cleaning epoxy grouts, scrubbing with a solution of bleach and water or vinegar and water usually works well.
Adapted Epoxy
There is yet another variety of hybrid grout that is available, which is o is an epoxy grout enhanced with Portland cement. This grout has the same characteristics as ordinary cement grouts, such as the need for routine sealing. Nonetheless, compared to ordinary cement grouts, they are stronger, harder, and more stain-resistant.
Grouts made of furan resin
While furan grout and epoxy are similar, furan grout is composed of extremely chemically resistant polymers of reinforced alcohols. The fufuryl alcohol in the mixture is the source of the name. This kind of grout contains no water at all. Furans are systems made up of two parts: an acid catalyst-containing filler powder and a furan resin. The furan resins cure thanks to the acid catalyst, which also produces a thermosetting resin with unparalleled chemical, physical, and thermal resistance.
Furan grout is frequently used to grout quarry tiles and paving stones. It is also advised for places that come into contact with grease and chemicals. Tile surfaces might be abrasive, non-slip, or smooth, depending on how the floor will be used. Before putting furan, wax should be applied to tile or brick surfaces to prevent discoloration. These grouts are typically employed in industrial applications like laboratories, meat plants, and dairies because of how tough they are to install.
When combining, caution must be used to prevent fume inhalation. Proper installation calls for specialized knowledge and needs to be done in a temperature range of 15 to 32 degrees Celsius.
Cost of installation
The area where the tile grout will be laid and the contractor’s degree of experience will determine the final cost.
