Waterproof microcement and low in VOCs | Efectto PU

Efectto PU, the waterproof microcement that redefines standards in construction and space renovation, stands out as the most mechanically resistant microcement low in VOCs on the market. Formulated with polyurethane, Efectto PU ensures efficiency, durability, and maximum protection in spaces exposed to humidity, making it the ideal professional choice for all types of projects, even the most demanding ones.

This microcement system facilitates application, optimising time without compromising quality. We make the difficult seem easy because professionals have never had it simpler: its water-based solvent-free formulation enables a waterproof and highly resistant finish, speeding up execution times for both indoor and outdoor projects. Once you try it, you’ll never look back.

Moreover, our waterproof microcement carries the CE marking, certifying its compliance with the quality and safety standards required by European regulations.

Mixed microcement for efficient applications

Designed to optimise professional projects without compromising the quality of the finish, Efectto PU is a waterproof mixed microcement that simplifies application by eliminating the need for mesh or pore fillers, thereby reducing steps and time. Even on vertical surfaces, its application is more efficient, allowing the use of a roller for quick and effective wall work. Forget complicated techniques: ease and efficiency in every layer.

Waterproof microcement before sealing

Efectto PU is the best ally for humid spaces as it can even be applied to bathtubs. A microcement with no limits, perfect for areas in constant contact with water, such as bathrooms and kitchens, thanks to its waterproof capacity—even before sealing, which ensures total protection against moisture. Its formulation ensures your spaces always look flawless and well-protected. However, it is important to note that it is not designed for use in swimming pools due to the negative pressure that is generated.

The toughest waterproof microcement on the market

With unmatched mechanical resistance, Efectto PU is ideal for enduring the most demanding conditions. Its exceptional abrasion resistance and ability to withstand the dragging of heavy objects make it the perfect choice for high-traffic and intensive-use areas. Thanks to its extraordinary durability, it maintains its appearance and functionality over time, establishing itself as the toughest waterproof microcement on the market.

Environmental commitment through low VOCs

In addition to being the toughest microcement on the market, this system offers an added value: its components are non-toxic. Water-based and low in VOCs (volatile organic compounds), Efectto PU ensures a safe working environment and reduces environmental impact.

It is a safe product for professionals and clients alike, posing no risks of allergies or irritations. By choosing Efectto PU, you opt for a microcement that ensures safe application and cares for the health of professionals, clients, and the planet.

Waterproof microcement that can be retouched

The versatility of Efectto PU allows for easy retouching, making maintenance and space renewal simpler while optimising long-term costs and time.

Waterproof microcement with no limits for interior and exterior

The waterproof microcement Efectto PU has no limitations. Not only is it effective indoors, but thanks to its UV resistance, this microcement ensures its colour and characteristics remain intact in outdoor applications, for example, on terraces. Efectto PU is a versatile mixed microcement for all types of projects, expanding design and functionality possibilities for any project.

Much better than epoxy

The Efectto PU waterproof microcement matches the strength of an epoxy, while overcoming its limitations: it doesn't yellow when exposed to sunlight, making it ideal for outdoors, and its low VOC content ensures a reduced environmental impact, increasing its added value compared to epoxy.
