The Kerakoll Active Prime Fix Rapid Universal Adhesion Promoter – 5kg offers a larger volume for professionals working on extensive tiling or flooring projects. Designed to enhance adhesion on various substrates, this rapid-drying, water-based primer is ideal for preparing surfaces before applying self-levelling compounds, cement-based adhesives, and finishing plasters. Its universal compatibility makes it a top choice for both absorbent and non-absorbent substrates, providing excellent coverage and performance in internal and external applications.
Key Features:
Superior Adhesion: The active cross-linking technology of Kerakoll Active Prime Fix creates a robust bond between the substrate and overlaying materials, ensuring a long-lasting and secure finish.
Rapid Drying Time: In just 15 minutes, this primer becomes touch dry, allowing for quicker application of subsequent layers, whether it be self-levelling compounds, adhesives, or plasters.
Versatile Surface Application: Suitable for various materials such as concrete, stone, ceramic, and even metal and wood panelling, this product ensures a smooth finish on both absorbent and non-absorbent substrates.
Surface Preparation Made Easy: By regulating the absorption of highly porous substrates, Active Prime Fix ensures a smooth, consistent application of finishing products and prevents the issues associated with excessive moisture absorption.
Environmentally Friendly: With low VOC emissions (EC1 Plus certified), this primer is safe to use in residential, commercial, and industrial spaces, even for indoor applications. It provides high performance while maintaining a minimal environmental impact.
Chemical Neutralisation: It effectively neutralises the chemical reactions found in gypsum and anhydrite-based substrates, improving the compatibility of overlays like self-levelling products, adhesives, and finishing plasters.
Applications:
Kerakoll Active Prime Fix in its 5kg size is perfect for larger commercial or residential tiling, flooring, and finishing projects. It can be applied to various substrates, including:
Self-levelling products
Cement-based adhesives and mineral mortars
Plasters and renders
Ceramic tiles, marble, and stone
Wooden floors and panels
Concrete, including smooth concrete surfaces
Gypsum-based substrates and prefabricated concrete
Flooring in epoxy resin and PVC
Its versatility makes it suitable for both floor and wall applications, providing professional results whether used on indoor or outdoor surfaces.
Installation Instructions:
Surface Preparation: Before application, ensure the surface is clean, dry, and free from dust, oil, grease, and any flaky material. For substrates that are particularly dusty or powdery, mechanical abrasion may be necessary to create a stable surface for application. Absorbent substrates should be firm and compact without any friable material.
Mixing: The product is supplied ready to use; however, for specific substrates, dilution with water may be required. For example:
For non-absorbent surfaces, mix briefly to ensure product homogeneity.
On calcium sulphate-based substrates, dilute 1 part primer to 3 parts water for the first coat. After the first coat dries, apply a second coat undiluted.
For highly porous substrates, dilute up to a 1:4 ratio to improve penetration and absorption regulation.
Application: Apply an even coat using a flat brush or roller. Make sure the first pass is followed by a second perpendicular pass to ensure full coverage. Allow the product to dry for approximately 15 minutes or until touch dry before proceeding with the next layer of adhesive or levelling compound. In highly porous or dusty areas, a second coat may be necessary to ensure optimal performance.
Post-Application: Ensure that the moisture content of the substrate is appropriate for the next layer of material, whether it’s adhesive or self-levelling compound. The primer enhances the workability of the finishing layer and ensures a smooth application, particularly when working with thin-layer self-levelling compounds.
Cleaning and Maintenance:
Any excess or residue of Kerakoll Active Prime Fix can be easily cleaned from tools with water, provided it is done before the product hardens. Once set, mechanical cleaning methods may be required. This product is environmentally safe, emitting low levels of VOCs, which makes it a great option for indoor projects.
Special Considerations:
Avoid application on substrates exposed to rising moisture or wet conditions.
Do not apply to highly flexible substrates or those prone to strong dimensional movement.
Ensure full compatibility with the materials you intend to overlay, as some substrates may require additional surface preparation.
Ensure the surface is dry and compact before application for best results.
