Using the right adhesive is crucial for strong and durable tile bonding. Kerakoll Biofix is a high-performance mineral adhesive designed for porcelain tiles, ceramic tiles, and natural stone.
It is a safe and dependable choice for a variety of surfaces because it guarantees superior adhesion with minimal chemical additions. To get the best results, proper mixing and application are essential. This guide will take you through the steps to use Kerakoll Biofix correctly.
Before applying Kerakoll Biofix, it’s important to prepare the surface properly. A well-prepared surface ensures better adhesion and long-lasting results.
Clean the surface: Remove dust, dirt, grease, or any other contaminants.
Check for damage: Ensure the surface is solid, level, and free from cracks.
Dampen highly absorbent surfaces: If the substrate is too dry, lightly dampen it with water or apply a primer like Active Prime Fix or Active Prime Grip.
Proper mixing is key to achieving the right consistency. Follow these steps to prepare the adhesive:
Use clean water – The recommended water quantity is:
Add powder to water: Always pour the powder into water, not the other way around, to avoid lumps.
Mix thoroughly: Use a mechanical mixer at low speed until the mixture is smooth and free from clumps.
Let it rest: Allow the mixture to sit for about 5 minutes, then mix again before applying.
Once mixed, Kerakoll Biofix should be applied immediately for the best bonding results.
Spread the adhesive: Use a notched trowel to spread a layer of adhesive onto the surface.
Ensure full coverage: For large tiles (over 60 cm), apply adhesive to both the surface and the back of the tile to ensure full contact.
Work in small sections: Apply only as much adhesive as you can cover within 30 minutes to prevent drying before tile placement.
Position tiles carefully: Place tiles onto the adhesive and press firmly to ensure proper bonding.
Check for proper adhesion: Lift a tile occasionally to check if the adhesive is fully covering the back.
Maintain even spacing: Use tile spacers to keep consistent gaps for grout.
Adjust within 30 minutes: If needed, reposition tiles within the adhesive’s open time.
Wait before grouting: Allow walls to set for 12 hours and floors for 24 hours before applying grout.
Avoid heavy traffic: Light foot traffic is possible after 2 days, while full strength is achieved after 4 days.
Keep the area dry: Protect from direct water exposure during curing.
Correctly mixing and applying Kerakoll Biofix ensures a strong and long-lasting bond for your tiles. You can get a polished finish with outstanding durability by following these easy steps. Whether for floors, walls, or natural stone installations, Kerakoll Biofix provides reliable adhesion with minimal environmental impact.
