ECO 420 – Wall and Floor Ceramic Adhesive

Preparation Stage

• Prepare the installation area. Tiles should be installed on a substrate that is stable, cured, and level.
• Install level markers and string lines to ensure straightness, precision, and ease of work during installation.
• Clear the substrate of any debris, dust, moss, or oil, as these contaminants can reduce adhesion strength.
• Pre-wetting is recommended to lightly dampen both the substrate and the tiles with water before starting.

Mixing Stage

• Pour approximately 10 liters of clean water into a mixing bucket for every bag of ECO-420 (40 kg).
• Gradually add the ECO-420 Tile Adhesive powder into the water.
• Stir the mixture until it reaches a smooth, lump-free consistency. Using an electric mixer is highly recommended for best results.

Application Stage

• Apply the adhesive manually using a notched trowel as per standard practices.
• The ideal adhesive bed thickness is ± 3 mm.

Important Precautions

• Do not add other materials such as cement, sand, or additives to the mix.
• Prepare only the necessary amount of mixture. Ensure the batch is used within a maximum of 60 minutes.
• Apply the adhesive tile by tile (or in small sections) to prevent the mixture from drying before the tiles are set.
• or large-format tiles (60×60 cm or larger) or tiles with uneven back surfaces, apply a thin layer of adhesive to the back of the tile (back-buttering) to ensure 100% coverage.
• Using a notched trowel prevents air from being trapped under the tile, ensuring a perfect bond and preventing tiles from lifting or popping.
