Cement Grout
Cement grout is a cement-based material used to fill the joints between tiles during a tile installation. It is made from Portland cement and contains pigments, fine aggregates, and additives that ensure durability and strength. Cement grout for tiles is a popular choice among tiling professionals as it fills tile joints, helps protect tile edges from chipping, and creates clean, uniform grout lines. This gives the installation a clean and finished look.
Once mixed with water and applied, cement grout hardens through a hydration process as it cures. The grout becomes strong and stable during this curing time, ensuring secure and firm joints.
As cement is naturally a porous material, it absorbs water quickly if the grout is left unsealed. Applying a grout sealer can help reduce staining and moisture penetration, especially in wet areas such as showers.
Types of Cement-Based Grout
There are two major categories of cement-based grout available. These are:
| Aspect | Sanded Cement Grout | Unsanded Cement Grout |
|---|---|---|
| Composition | Contains fine sand (aggregate) for added strength | No sand; smooth, fine consistency |
| Joint Width | Suitable for wider joints (≥ 1/8 inch) | Best for narrow joints (≤ 1/8 inch) |
| Strength & Durability | Higher strength; resists cracking and wear | Lower strength; prone to shrinkage in wide joints |
| Surface Compatibility | May scratch delicate surfaces | Safe for glass, polished stone, and metal tiles |
| Application Areas | Floors, high-traffic zones, large tiles | Walls, backsplashes, decorative and vertical surfaces |
| Finish | Slightly textured due to sand | Smooth and uniform finish |
| Workability | Slightly harder to apply in tight joints | Easier to spread and fill small spaces |
The choice between these two types depends on the material of the tile, joint size, and installation space available.
Due to its versatility, easy application, and compatibility with ceramic, porcelain, and many natural stone tiles, cement grout continues to rule the market of grout and is widely used in both residential and commercial spaces.
