What is Tile Grout?
Grout is a combination of cement, sand, and rock that is often dyed a specific color to match different shades and patterns of tile. When a tile is applied to a floor or wall, it is set in place using an adhesive. It is necessary to leave joints in between the tiles to allow the adhesive to dry and the moisture to escape. This drying process can take up to 30 days to completely cure, requiring the use of a porous grout to fill the joints and strengthen the floor or wall. The porousness in the grout allows the moisture to escape from the adhesive and prevents the tile from buckling.
What type of grout do I have?
There are two major types of grout, sanded and unsanded.
Sanded grout is generally used for wider grout lines and on larger floor areas. This grout has a sandy rock-like feel and when it is cleaned properly, the pores are opened allowing for color or clear protective sealant to be applied.
Unsanded grout is generally used for tighter grout lines and on shower walls and floors where smaller tiles are installed. This grout has a smooth feeling to it and usually cannot be color sealed due to the lack of pores. However, a clear protective sealant can be used.
Why does grout get dirty?
Grout is like a sponge with thousands of little holes in it.
The same porous properties that allow moisture to escape after tile installation will absorb dirt stains and spills. This can cause the grout to become stained or discolored. Tile is very easy to clean and maintain using a mop and a basic solution of water and a mild detergent. During the process of mopping the tile, the mop gets dirty which results in the spreading of dirty water throughout the grout. The grout, being sponge-like, immediately absorbs all the dirty water. Every time a tile floor is mopped, the grout will become one shade darker than it was previously. It is typical for homeowners who mop their floor often to have dirtier, darker grout lines. More often than not- the harder you try to clean the grout, the dirtier it gets. Instead of mopping with lots of water, try following our tips for keeping tile floors in great shape.
