Grout is an important part of your tile floor. Grout comes in many variations, chemistries, sanded or unsanded and colors. It is usually a cement or epoxy based material that is used to fill between the tile spaces. look at here wholesale
The most common delineation of cement based grout are sanded and unsanded. Sand is typically utilized in order to reinforce the grout, allowing it to span a boarder grout line without cracking, a grout joint of 1/8″ or larger is typically going to be sanded (unless working with a soft stone such as marble). The sand also provides rough to the touch texture, versus unsanded. That said, if you are working with a tile that is relatively soft, and prone to scratches, such as marble, one would want to avoid sand, as a grain of sand is an aggressive scratch creating abrasive once trapped under foot.
Unsanded grout is also known as “wall grout.” It has the basics of sanded grout only without the sand. This type of grout is mainly used on ceramic tile and polished marble. It is used with grout joints that are less than 1/8″. This grout should always be sealed after installation to ensure longevity and appeal.
Cement based grouts are known to be porous, and therefore need to be sealed, else they will stain. Sealing cementitious grout is the key to preventing staining. Fail to seal or maintain your seal and you will see your grout lines becoming “dirty” over time. A penetrating sealer is the most common used sealer, however it suffers the drawback that the applicator while he can see that the grout has been wet by the sealer, cannot determine whether he has saturated the surface. Fail to saturate the surface and you will see localized staining over time. Enter ColorSeal technology, which incorporates a the grout color into the sealer, and in so doing allows the applicator to see whether enough material has been applied. If it has not it is absorbed and one can see a shade difference.
