In modern construction, the quality of floor leveling directly affects the subsequent installation of flooring, PVC materials, carpets, and epoxy coatings. Self-leveling mortar has become a mainstream leveling material due to its ease of application, excellent flow properties, and high surface flatness. Within self-leveling systems, the addition of Polvere polimerica ridisperdibile (RDP) is a key factor in enhancing floor flatness, bond strength, and abrasion resistance.
Self-leveling mortar is a dry-mix material primarily composed of cement as the main binder, combined with fine aggregates, fillers, and various functional additives. After mixing with water, the slurry can flow naturally across the floor surface and self-level, ultimately forming a strong, high-flatness substrate.
The core performance characteristics of self-leveling mortar include:
Achieving these properties solely with a cementitious system is often insufficient. Therefore, the introduction of high-performance polymer materials—Redispersible Polymer Powders—is essential.
Polvere di polimero ridisperdibile is a powdered adhesive material produced by spray-drying a special emulsion. Upon contact with water, it redisperses into an emulsion state. As the water evaporates, it forms a continuous, flexible polymer film within the mortar.
This polymer film exhibits the following characteristics:
In self-leveling mortar, the RDP combines with cement hydration products to form a “polymer-cement composite structure,” significantly improving the overall material properties.
High-quality VAE-type RDP (Vinyl Acetate–Ethylene Redispersible Polymer Powder) offers excellent dispersibility, improving mortar lubrication, resulting in more uniform slurry flow and reducing segregation and bleeding.
For example, the TENESSY™ 5560 model offers excellent workability, is particularly suitable for self-leveling cement-based mortars, effectively enhances flow stability, and ensures a smoother, more refined self-leveling finish.
Self-leveling materials are prone to developing shrinkage stress during hardening. The flexible polymer network formed by RDP can buffer internal stresses, reducing shrinkage cracks, thereby ensuring overall flatness after large-area application.
RDP enhances the mortar’s adhesion to concrete substrates, preventing issues like hollowing and delamination, ensuring the leveling layer remains stable long-term without warping or blistering.
The floor leveling layer requires not only flatness but also good abrasion resistance, especially in commercial, industrial, or high-traffic areas.
RDP plays a key role in the following aspects:
The polymer film enhances mortar toughness, increases flexural strength and impact resistance, preventing surface dusting.
Models like TENESSY™ 5516 e 5518 feature:
RDP fills the micro-porous structure between cement particles, forming a denser internal matrix, thereby improving abrasion and compressive resistance.
When subsequent flooring or epoxy materials are installed, good abrasion resistance prevents surface sanding and peeling, extending floor service life.
