Description
ARDEX K 55 FAST is a cutting-edge subfloor smoothing compound formulated for rapid hardening, ideal for projects that require minimal installation time for floor finishes. When mixed with water, it creates an exceptionally fluid, self-levelling mortar that can be applied in a single operation, ranging from a feather edge to a maximum thickness of 10 mm. Depending on the substrate and application thickness, the surface can typically be walked on within approximately 30 minutes at 20°C. Once sufficiently hardened, floor coverings can be installed as soon as 60 minutes later for applications less than 3 mm thick, with the appropriate adhesive recommended for such reduced thicknesses. Notably, after installation, the floor should not endure heavy or moving loads for at least 48 hours.
Key Points
- Rapid Hardening: ARDEX K 55 FAST allows for quick installation, typically walkable within 30 minutes and ready for floor covering in as little as 60 minutes for applications under 3 mm thick.
- Single Application: It is designed to level and smooth subfloors in one application, effectively addressing issues with uneven or damaged concrete, adjusting floor tolerances, and renovating old subfloors before new coverings.
- Fluid Self-Levelling: The compound produces a fluid, self-levelling mortar that can be applied from a feather edge up to 10 mm thickness in a single operation.
- Load Limitations: Post-installation, it is crucial to avoid heavy or moving loads on the newly applied surface for at least 48 hours to ensure proper curing and stability.
