laatoitusliiman

Laatoitusliima, often referred to as tile adhesive or thin-set mortar, is a specially formulated cement-based adhesive used for fixing tiles to various surfaces. Its primary function is to create a strong and durable bond between the tile and the substrate, ensuring the tiles remain securely in place for the intended lifespan of the installation. The composition of laatoitusliima typically includes Portland cement, fine aggregates like sand, and various polymers and additives that enhance its performance.

The polymers in laatoitusliima are crucial for improving adhesion, flexibility, and water resistance. These additives allow the adhesive to accommodate minor movements in the substrate without cracking, which is particularly important in areas subject to temperature fluctuations or vibration. The fine aggregate provides body and workability, while the cement acts as the binder. When mixed with water, laatoitusliima forms a paste that can be spread easily with a notched trowel. The notches create a uniform pattern of adhesive on the substrate and the back of the tile, ensuring full coverage and optimal adhesion.

Laatoitusliima is available in various formulations designed for specific applications. Some are suited for interior use on walls and floors, while others are formulated for exterior applications, high-moisture areas like bathrooms and kitchens, or for bonding large format tiles. The choice of laatoitusliima depends on factors such as the type of tile being used (e.g., ceramic, porcelain, natural stone), the substrate material (e.g., concrete, plasterboard, cement board), and the environmental conditions of the installation. Proper mixing and application are essential for achieving a successful and long-lasting tile installation.
