Adhesive Mortar for EPS/XPS board is a high-quality construction adhesive. It is specifically designed for bonding expanded polystyrene (EPS insulation board) and extruded polystyrene (XPS boards) to mineral substrates such as concrete, plaster, etc. It is featured by excellent long-term bond strength. This makes it ideal for a wide range of applications in both interior and exterior construction projects. This mortar is also suitable for bonding with other insulation substances. For example, mineral wool and glass wool, to mineral substrates.
2 Key Ingredients for Your EPS Insulation Adhesive
There are many types of adhesive mortars for EIFS building materials. The most common type is a mortar bonding adhesive, used to bond the EIFS material to the masonry.
EPS Adhesive on masonry bonds EIFS to masonry surfaces. It is a strong, durable, and weather-resistant adhesive. It applies to a lot of masonry surfaces. It’s easy to use and provides strong adhesion and flexibility between the EIFS and the masonry surface.

HPMC hydroxypropyl methylcellulose is an essential component of any EPS bonding mortar. WOTAI HPMC allows proper adhesion between the EPS insulation board and the mortar while providing a waterproof barrier. It prevents moisture from seeping into the EPS and causing further problems.

RDP powder from WOTAI is used in EPS bonding mortar to improve efficiency and maximize product performance. The EIFS requires a certain amount of RDP powder to function properly. Adding RDP powder to the EPS bonding mortar improves the overall performance of the EIFS.
EPS Adhesive Formulation with WOTAI Additives
EPS Adhesive is a cement-based adhesive that is ideal for year-round use. This product comprises Portland cement, texturing aggregate, mineral fillers, hydrated lime, and reinforcing fibers. EPS Adhesive has excellent durability, frost resistance properties, and quick drying times. Storing the EPS Adhesive is important to ensure consistent performance throughout the application process.
Cement-based plaster is essential for EIFS/ETICS components. When added with HPMC, it provides excellent adhesion and cohesion to the substrate, indispensable for a successful EIFS/ETICS installation.
