What is grout?

Grout is largely used in the construction process. This kind of material is used to fill the small holes, spaces, joints, cracks and crevices left after placing tiles, marbles etc on the floors and walls of the bathroom. The grout is applied on ceramic tiles, joints and other requisite areas once the process of placing the flooring and wall covering material is over. A thick layer of grout is evenly applied over the entire area with more attention to the joints and crucial areas. The substance hardens within a few hours from the point of application.

Components of Grout

Grout is prepared by mixing water, sand, binding material such as white cement etc. in adequate proportion and required thickness. In order to enhance the look of the colored tiles, grout mixture is often mixed with matching color. Once the application process is completed the grout is allowed to dry up properly. After this the grout sealer is applied on the dry grout layer to ensure a protective cover to obstruct the contact with liquid substances such as oils, lubricants, water etc.

Types of Grout

There are different types of grout viz. flooring grout, structural grout, tiling grout, resin grout etc. While structural grout is used to fix metallic objects to the concrete structures, the tiling and floor grout are largely used for adding strength to the joints of wall tiles, floor tiles, marbles, and mosaic constructions.

The tiles in the bathroom are generally fixed with the application of sanded grout for if the size of the tiles is more than 1/8 inches and non sanded grout if the tiles are less than 1/8 inches. The grout is applied after 24 hours from the completion of fixing the tiles on the walls and the floors. This provides a strong bonding of the tiles. This kind of grout is relatively fragile and porous in nature.

Joint Size

The joint size between the tiles determines the type of grout required for filling these gaps. It is the gap between the two adjacent tiles. The grout plays an important role in providing a strong binding of the tiles so that they do not come out once they start contacting water. If the joint size is wider than 1/8 inches then you should use sanded grout and if the gap is narrower than 1/8 inches then the non sanded grout is required to fill gap and act as an adhesive. Once the grout starts drying they tend to shrink resulting reduction of size. This may lead to separation of the grout from the ends of the tiles if non sanded grout is used for filling wider joints. The sand property prevents the sanded grout to shrink resulting in compact joining with the tiles.

Grout Application and Removal Tools

There is a wide range of manual as well as machine tools used for the application and removal of the grout. The grout saw/ scraper is used to remove the grout after the hardening of the material. This manual tool has blades made of tungsten carbide. The grout float is used to spread the grout firmly and evenly. The grout attachment is used during the removal of the grout material from the tiles and floors. The trowel is another tool used for application of grout.
