Mapei Acrylic Flooring Adhesive, 14Kg, Suitable for LVT and Resilient Floor Coverings with Strong Initial Tack

Mapei Ultrabond Eco 375 is a solvent‑free, water‑based tile adhesive packaged in a 14 kg bucket. It’s designed for interior use and is suitable for bonding ceramic tiles and some natural stones to interior walls and floors. It offers easy application, a long open time, and strong adhesion to various substrates.

It can be used on interior wall and floor substrates, including plaster, cement and concrete, as well as non‑porous building materials. It’s intended for interior surfaces and should not be used outdoors or in exterior conditions.

Ultrabond Eco 375 is suitable for ceramic tiles and many natural stone tiles on interior applications. It provides strong bond strength across a variety of substrate types when used as directed.

Key specs include interior use on walls and floors, solvent‑free and water‑based composition, a 5 mm notched trowel for spreading, and compliance with EN standards 14579 and 1062. The product is UV, weather, and freeze‑thaw resistant, contributing to longevity in appropriate indoor environments.

Start with a clean, dry substrate. Apply the adhesive with a 5 mm notched trowel to achieve an even bed. Press tiles firmly into the adhesive (back‑buttering may be used for larger formats). Maintain an appropriate open time before fitting subsequent tiles, then wipe off any excess adhesive before it sets. Allow the adhesive to cure before grouting according to tile size and environmental conditions.

Compared to traditional solvent‑based adhesives, Ultrabond Eco 375 is solvent‑free and water‑based, offering easier handling and lower VOCs while maintaining strong adhesion for interior tiles. For example, Mapei Adesilex P9 is another interior tile adhesive option on Fepy that serves similar applications but differs in formulation and open time characteristics.

Prepare the substrate to be clean, dry, and free of dust, oils, or loose material. For many interior substrates, priming may not be required, but always follow the product guidance for specific substrates and tile sizes. If you’re working with particularly porous or challenging substrates, check for any substrate pretreatments recommended by Mapei or Fepy’s listing for this product.

Yes. Ultrabond Eco 375 is solvent‑free and water‑based, which generally offers lower VOC emissions. It complies with relevant EN standards (EN 14579 and EN 1062) and is designed for interior use. As with any adhesive, wear appropriate protective gear (gloves and eye protection) and ensure adequate ventilation during application.

Store the product in a cool, dry, well‑ventilated place away from direct heat and moisture. Keep the container tightly closed when not in use. While exact shelf life can vary by storage conditions, a well‑sealed 14 kg/15 kg package typically remains usable for an extended period if stored properly.

Ultrabond Eco 375 is intended for interior applications. For exterior or damp area projects, use a product formulation specifically rated for exterior use and moisture exposure, as exterior conditions and wet environments require different performance criteria.

Choosing Ultrabond Eco 375 provides a solvent‑free, user‑friendly interior tile adhesive with strong bonding and long open time, which can improve installation efficiency and tile performance in interior settings. If you’re considering value, compare purchase price, coverage per bag, ease of use, and required substrate prep against other interior adhesives on Fepy to determine the best overall fit for your project. If you’re uncertain, checking the product’s review history and how it performs on typical interior substrates can help with the decision.
