ARDEX P150 Reinforced Two-Component Bonding Slurry (Sand Slurry) consists of a high-polymer-content water-based emulsion combined with a powder component made of special cement, selected graded aggregates, and special additives. After mixing, it forms a brushable slurry. It can be used for interface treatment on low water absorption tile backs, and for interface reinforcement treatment between interior/exterior substrates such as concrete and masonry and mortar levelling layers, improving bond strength.
