A430 – A450 Porcelain Tile Adhesive

Description

This premium adhesive is a sophisticated blend of hydraulic binders, mineral aggregates, and specialized organic/polymeric additives. It is engineered for the high-strength bonding of tiles, ceramics, porcelain, and both natural and synthetic stones. The product is versatile enough for application on cement, stone, brick, ceramic, and gypsum surfaces. It is suitable for both interior and exterior use (building facades), including floors and walls. Furthermore, it is highly recommended for surfaces with underfloor heating, balconies, patios, swimming pools, gypsum blocks, lightweight concrete, and overlays on old stonework.
​
Application Guidelines:
​To prepare the mixture, combine one 20 kg bag of A430 adhesive with approximately 4 to 5 liters of clean water. It is essential to use a mechanical mixer to achieve a smooth, uniform paste. If the project requires the Highflex L400 supplementary liquid, add at least 1 liter per bag into the mix, reducing the water volume accordingly.
​Allow the mixture to rest for 5 to 10 minutes to reach full consistency, then remix for an additional minute. Using a notched trowel and the “double-back” method, apply the adhesive to both the substrate and the back of the tile, ensuring the ridges run in the same direction. After placement, apply uniform pressure or light impacts to expel trapped air. Wait at least 72 hours before grouting. During this period, avoid applying pressure or causing vibrations that might displace the tiles.
​
Pre-Installation Requirements:
​The substrate must be completely free of dust, debris, and grease. When installing over old tiles or stone, mechanically abrade or scratch at least two-thirds of the existing surface to ensure a strong bond. For gypsum-based surfaces, the area must first be scratched and then treated with a suitable primer before applying the adhesive.
