Kerakoll Bioflex White Flexible Mineral Tile & Stone Adhesive – 20 kg

Kerakoll Bioflex White is an eco-friendly, highly polymer-modified mineral adhesive engineered for high-performance fixing of vitrified tiles, porcelain slabs, marbles, and natural stones. Formulated using pure regional minerals, this low-carbon cementitious adhesive provides an exceptional structural bond, sustained resistance to environmental aging, and excellent workability on both floors and walls.

Its non-sag rheology and water-resistant composition make it the ideal professional-grade solution for demanding interior and exterior installations, safely handling everything from residential wet areas to exposed outdoor balconies and swimming pools.

• Highly Polymer-Modified: Offers premium shear bond strength and excellent shock absorption to manage substrate movement and thermal variations.

• Pure White Base: Formulated to eliminate dark shadowing, ghosting, or tint bleed-through when installing translucent glass mosaics, light quartz, and light natural marble profiles.

• Thick Bed Capability: Formulated to adjust seamlessly for adhesive bed thicknesses up to 15 mm, making it easy to compensate for minor substrate irregularities.

• No-Sag Thixotropic Formula: Provides excellent initial grab and vertical slip resistance, keeping heavy wall tiles and massive stoneware panels perfectly in place.

• Prolonged Workability: Features an extended open adjusting window ($\ge$ 30 minutes) and a reliable pot life, allowing installers plenty of time to align layouts flawlessly.

• Weather & Water Resistant: Outstanding heat-aging durability makes it highly capable in high-stress outdoor environments like terraces, fountains, and water bodies.

How to Use for Best Results

1. Substrate Preparation: Substrates must be compact, fully cured, completely structural sound, and clear of oil, grease, old adhesive residues, curing compounds, laitance, or loose dust particles.

2. Mixing: Pour clean water into a mixing bucket and slowly stir in the Bioflex White powder. Mix continuously with a low-speed mechanical mixer ($\approx$ 400 rpm) until a smooth, lump-free paste is achieved. Let the mix rest for 3 to 5 minutes, then stir briefly again before use.

3. Application Technique: Comb the mixed paste onto the substrate surface utilizing an appropriately sized notched trowel. Apply only enough material that can be comfortably tiled within the adhesive's active open time window.

4. Tile Embedding: Press the tile firmly into the wet mortar ridges using a slight twisting motion, tapping down with a rubber mallet to guarantee absolute contact transfer. For heavy vitrified slabs or external environments, the double-spreading (back-buttering) method is highly recommended to eliminate hollow air voids underneath.
