Ardex E 25 Resilient Emulsion Additive for Self-Leveling Underlayment and Concrete Topping, Improves Flexibility and Flexural Strength for ARDEX K 15 and K 520, Light Blue, 1 Gal (3.78 L), 12214

The ARDEX E 25 Resilient Emulsion (12214) is a high-performance, polymer-modified additive designed to significantly enhance the elasticity, cohesion, and flexural strength of self-leveling underlayment systems. Developed by ARDEX, this advanced emulsion is specifically formulated for use with ARDEX K 15 Premium Self-Leveling Underlayment and ARDEX K 520 Self-Leveling Concrete Topping. By modifying the internal structure of these systems, ARDEX E 25 increases the modulus of elasticity and strengthens the overall matrix, resulting in a more durable, flexible, and crack-resistant flooring base that performs reliably over time. In demanding construction environments, subfloors are frequently exposed to movement, vibration, temperature changes, and structural deflection that can lead to cracking or failure in traditional underlayments. ARDEX E 25 addresses these challenges by improving both cohesive strength and flexibility, allowing the underlayment to absorb stress and movement without compromising integrity. It is particularly effective for installations over difficult substrates such as cutback adhesive residues, metal surfaces, and mesh-reinforced wood subfloor systems, where enhanced bonding performance and flexibility are essential for long-term success. This resilient emulsion is also ideal for high-stress applications when used in combination with ARDEX K 520, especially in environments subject to heavy rolling loads such as forklift traffic. Warehouses, distribution centers, manufacturing facilities, and commercial spaces benefit from the increased durability and resistance to stress-related cracking that ARDEX E 25 provides. By reinforcing the underlayment system, it helps prevent surface degradation, delamination, and premature wear, ensuring a longer-lasting and more dependable flooring installation. Application is straightforward and designed to integrate seamlessly into standard mixing procedures. ARDEX E 25 is first combined with water before adding the underlayment powder; 2 quarts (1.9 L) with 6 quarts of water for ARDEX K 15, or 2 quarts (1.9 L) with approximately 4.5 quarts (4.25 L) of water for ARDEX K 520. Once mixed, the emulsion disperses evenly, maintaining excellent workability while enhancing performance. This allows installers to achieve superior results without altering their workflow, making it an efficient and practical solution for both small-scale and large commercial projects. Packaged in a convenient 1-gallon (3.78 L) container, ARDEX E 25 is easy to handle, store, and transport on the jobsite. It should be kept in a cool, dry environment, protected from direct sunlight, heat, and freezing conditions to preserve its performance characteristics, and offers a shelf life of up to one year when properly stored. Whether used in residential, commercial, or industrial applications, ARDEX E 25 delivers a critical upgrade in strength, flexibility, and reliability, making it an essential component for achieving high-performance, long-lasting flooring systems.
