Description
ARDITEX NA 25Kg Subfloor Levelling Compound
ARDITEX NA 25Kg is a high-performance, two-part self-levelling and smoothing compound from ARDEX, designed for professional flooring preparation. This ultra-rapid setting, protein-free and ammonia-free latex levelling compound delivers exceptional adhesion, flexibility, moisture resistance, and improved flow, making it one of the most versatile subfloor levelling compounds available for commercial and domestic flooring projects.
Ideal for levelling uneven internal subfloors, ARDITEX NA can be used over almost all common substrates without priming, including concrete, cement and sand screeds, ceramic tiles, terrazzo, quarry tiles, flooring-grade asphalt, bitumen adhesive residues, plywood, and steel floors. Its advanced formulation allows direct application to damp concrete and use beneath an ARDEX Damp Proof Membrane, helping to save valuable installation time on site.
With rapid drying performance, resilient floor coverings can typically be installed after just 4 hours, while ceramic and porcelain tiles can be fixed in as little as 3 hours.
