Grout is a dense fluid that hardens used to fill gaps or as reinforcement in existing structures.[1] Grout is generally a mixture of water, cement, and sand, and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of precast concrete, filling voids, and sealing joints such as those between tiles. Common uses for grout in the household include filling in tiles of shower floors and kitchen tiles. It is often color tinted when it has to be kept visible and sometimes includes fine gravel when being used to fill large spaces (such as the cores of concrete blocks). Unlike other structural pastes such as plaster or joint compound, correctly mixed and applied grout forms a water-resistant seal.
Although both grout and its close relative mortar are applied as a thick suspension and harden over time, grout is distinguished[2] by its low viscosity and lack of lime (added to mortar for pliability); grout is thin so it flows readily into gaps, while mortar is thick enough to support not only its own weight, but also that of masonry placed above it.[1]
Grout varieties include tiling, flooring, resin, nonshrinking, structural, and thixotropic grouts.[3] The use of enhancing admixtures increases the quality of cement-based materials and leads to greater uniformity of hardened properties.[4]
Tiling grout is often used to fill the spaces between tiles or mosaics and to secure tile to its base. Although ungrouted mosaics do exist, most have grout between the tesserae. Tiling grout is also cement-based, and is produced in sanded and unsanded varieties, which affects the strength, size, and appearance of the grout.[5] The sanded variety contains finely ground silica sand; unsanded is finer and produces a smoother final surface. They are often enhanced with polymers and/or latex.[6]
Structural grout is often used in reinforced masonry to fill voids in masonry housing reinforcing steel, securing the steel in place, and bonding it to the masonry.[2] Nonshrinking grout is used beneath metal bearing plates to ensure a consistent bearing surface between the plate and its substrate, which adds stability and allows for higher load transfers.[7]
From the different types of grout, a suitable one has to be chosen depending on the load. For example, a load up to 7.5 tons can be expected for a garage access [two-component pavement joint mortar (traffic load)], whereas a cobbled garden path is only designed for a pedestrian load [one-component pavement joint mortar (pedestrian load)]. Furthermore, various substructures determine whether the type of grout should be permanently permeable to water or waterproof, for example, by concrete subfloor.
Prevention is the best cure for grout problems. Since cement grouts are especially porous, they can stain and are easily damaged by water. Make sure to use a penetrating grout sealer as soon as you finish installing your tile. Reseal existing sanded or unsanded grout every two years or so.

The key to a healthy surface is healthy grout! Tiles may last forever, grout does not! Grout, the stuff between the tiles, is porous and absorbs spills, dirt, and grime like a sponge. If not cared for, the grout will become stained and damaged and will eventually need to be replaced.
Grout sealing is one of the most important steps toward maintaining a healthy grout surface. It is our recommendation to seal existing grout in any tiled area as well as a brand-new installation after our deep cleaning service.
Grout sealers come in two varieties: membrane-forming and penetrating. The first type is prone to peeling or getting cloudy when residual moisture from mastic or underlayments pushes to the surface of the tile. Penetrating sealers, which still breathe after soaking into tile and grout, are preferable.
The new generation of epoxies contain detergents in the hardeners, which make for quick cleanup with water and improve workability. Because epoxy can discolor porous surfaces, such as unglazed quarry tiles or limestone, these should be sealed before grouting. But its stain resistance, hardness, and durability make epoxy grout the best choice for showers, kitchen counters, backsplashes, floors, and other heavy-traffic areas.

Read all installation instructions before installation and reference ANSI A108.10-1999. Slightly moisten the tile surface with a damp, rounded grout sponge just before application. Force the grout into the joints with a medium-to-hard rubber float held at a 45-degree angle to the tile surface. Make sure all joints are full and are free of voids and gaps. Remove excess grout from the tile surface, holding the float at an almost 90-degree angle to the surface and moving the float diagonally to the joints while the grout is still fresh. Ensure grout surface is flush with the tile edge. Once grouting is complete, replace the protective coated inner lid in the pail by pushing down until it contacts the unused grout. Make sure the plastic lid is closed tightly and the product is good for reuse.
CLEAN-UP
Cleaning should begin after the surface begins to dry and skin-over, usually within 5 to 10 minutes, depending on ambient conditions and the porosity of the tile. Grout areas between 25 and 40 sq. ft. (2.3 to 3.7 m2) at a time so that cleaning can begin before the grout dries on the tile surface. Using a damp, rounded grout sponge, move across the tile surface in a circular motion to loosen grout and to shape the joints. Drag a clean, damp sponge diagonally across the tile joints, applying light pressure. Use one side of the sponge for each pass over the tile, rinsing the sponge after the second pass. Change the water bucket frequently to prevent the development of a haze on the tile surface. If grout residue is observed on the tile surface, a final wash can be performed about 1 hour after the initial wash. Use clean water and a clean, white, damp nylon scrub pad to loosen any remaining grout residue and a moistened sponge to remove the residue. Do not leave standing water on grout surface during clean-up.
PROTECTION
Do not disturb grout or walk over installed tiles for at least 24 hours after setting. Do not allow heavy traffic over installed tiles for at least 72 hours after setting. For residential showers and tub surrounds, restrict use for 72 hours after grouting. Do not allow dirt or debris to become embedded in the grout joints as they are curing.
For unsightly efflorescence to be present you must have three things: water, water-soluble minerals, and a pathway such as capillaries for the moisture to escape and leave behind the minerals. To avoid efflorescence, you need to eliminate at least one of those three components. Several SikaTile grouts are formulated to avoid efflorescence.
