Mixed microcement for efficient applications

Designed to optimize professional projects without sacrificing finish quality, Efectto PU is a waterproof mixed microcement that simplifies application by eliminating the need for mesh or primers, thereby reducing steps and time. Even on vertical surfaces, its application is more efficient, as it can be applied with a roller, enabling quick and effective work on walls. Forget complicated techniques: ease and efficiency in every layer.

Waterproof microcement before sealing

Efectto PU is the best ally for humid areas, as it can even be applied in bathtubs. A microcement without limits, perfect for areas in constant contact with water, such as bathrooms and kitchens, thanks to its waterproof capabilities even before sealing, ensuring total protection against moisture. Its formulation guarantees spaces that always look impeccable and 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 hardest waterproof microcement on the market

With unmatched mechanical resistance, Efectto PU is ideal for withstanding the most demanding conditions. Its excellent resistance to abrasion and the dragging of heavy objects makes it the perfect option for high-traffic and heavy-use areas. Thanks to its exceptional durability, it maintains its appearance and functionality over time, standing out as the hardest waterproof microcement on the market.

Environmental commitment with low VOCs

In addition to being the hardest microcement on the market, this system stands out for its added value: its components are non-toxic. Water-based and with a low content of VOCs (volatile organic compounds), Efectto PU ensures a safe working environment and reduces environmental impact.

It is a safe product for professionals and clients, posing no risk of allergies or irritation. Choosing Efectto PU means opting for a microcement that provides safe application, thus protecting the health of professionals, clients, and the planet.

Waterproof microcement that’s also easy to touch up

Efectto PU’s versatility allows for easy touch-ups, facilitating maintenance and renovation of spaces, optimizing costs and time in the long run.

Waterproof microcement with unlimited possibilities for interior and exterior

The waterproof microcement Efectto PU has no limitations. Not only is it efficient indoors, but thanks to its UV resistance, this microcement ensures that its color and properties 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 in any setting.

Way better than epoxy

The Efectto PU waterproof microcement matches the durability of an epoxy, while overcoming its limitations: it doesn't yellow when exposed to sunlight, making it perfect for outdoor use, and its low VOC level guarantees a lower environmental impact, enhancing its added value over epoxy.
