Not all Grouts are created equal - Tiles versus Cement Blocks
Tile Grout: This type of grout is typically used for filling the gaps between tiles on walls or floors. It helps create a smooth, uniform surface while preventing water and dirt from getting into the seams. Tile grout comes in two main varieties: cement-based grout (which is the most common) and epoxy grout (which is more resistant to stains and moisture). Cement Block Grout: Referred to as mortar grout or concrete grout, is much thicker and more robust. Its primary purpose is to fill the hollow cores of concrete blocks, providing structural stability and supporting the load-bearing capacity of a wall. It is typically made from a mix of cement, sand, and water, with additives to improve flow and bonding properties.
Strength and Durability
Tile Grout: While tile grout is strong enough to hold tiles in place and resist wear over time, it is not designed to bear significant weight or structural pressure. Its primary focus is on aesthetic appeal and functionality within the confines of the tile layout. Cement Block Grout: This grout is formulated to be much stronger to support the weight and pressure exerted by the cement blocks. It helps to ensure the structural integrity of walls and foundations, and its strength is key to maintaining the overall stability of a building.
Application Techniques
Tile Grout: Typically applied using a grout float and then wiped off the surface of the tiles to leave grout only in the joints. It’s crucial to remove excess grout promptly to avoid staining tiles. Cement Block Grout: Applied more directly into the block cavities, often with the use of a Grout Pump or manual pouring. The application method depends on the size of the block cavities and the scope of the wall being constructed.
