High-Performance Slab Adhesive-A410

Description

A 410
High-Performance Slab Adhesive (Powder-Based)
Single-Component System
​
Product Characteristics
​A 410 is a specialized single-component adhesive formulated from high-grade mineral powders, organic additives, and advanced polymers. Specifically reinforced with synthetic fibers, this product is designed for high-durability bonding on both floors and walls, suitable for interior and exterior environments. Its versatile formulation allows for reliable application on gypsum-based substrates and surfaces equipped with underfloor heating systems. It is an ideal choice for high-traffic areas, bathrooms, balconies, patios, and swimming pools.
​
How to use:
​Combine one 20 kg bag of A410 with approximately 4.5 to 5 liters of clean water. It is mandatory to use a mechanical mixer to ensure a smooth, lump-free paste. If the mixture remains too stiff, gradually add a small amount of additional water and remix until the desired consistency is achieved.
​Allow the adhesive to rest for 5 to 10 minutes to activate its chemical properties, then remix for one final minute. Using a notched trowel, apply the adhesive using the “double-spread” technique (to both the substrate and the back of the slab), ensuring all ridges are pulled in the same direction. Once the slab is in place, use a vibration tool to expel any air trapped underneath. Grouting should be deferred for at least 72 hours. During this curing phase, protect the installation from any pressure or vibrations that could lead to slab displacement.
​
Substrate Preparation
​The installation area must be completely sanitized from dust, debris, and oily residues. For “tile-on-tile” or “tile-on-stone” applications, mechanically abrade (scratch) at least two-thirds of the existing surface. For gypsum-based surfaces, the area must be scratched and treated with a high-quality primer before applying the adhesive.
