PU-Based Tile Adhesive (polyurethane adhesive) is a moisture-curing, paste-like product that combines convenience with superior performance. Supplied ready-to-use in tubs or cartridges, it doesn’t require mixing like cement mortars. The adhesive offers excellent initial tack and resists vertical slip, making it easy to apply on walls and uneven surfaces. Unlike standard cement-based adhesives, PU-based formulations are highly water-resistant and flexible, making them ideal for high-humidity areas like bathrooms, showers, and even saunas.

Beyond moisture resistance, PU adhesives bond strongly to diverse substrates such as drywall, plaster, concrete, metal, and thermal boards—allowing you to tile over unconventional backgrounds . They cure via atmospheric moisture, reaching full strength within hours to days depending on conditions. While generally more expensive than cement adhesives, their versatility, strong adhesion, and durability in damp environments make them a smart choice for specialized tiling applications.
