Viero OLTRE Microcement | Step 4. Top 2K (Protective finish)

Viero OLTRE Top 2K is the final step in the OLTRE microcement system - an advanced, two-component polyurethane topcoat designed to protect and seal your decorative finish. Applied after the Style layer (Step 3), Top 2K provides a durable, semi-opaque protective barrier that enhances the longevity and performance of walls and floors, especially in wet or high-traffic environments.

Its water-based, low-VOC formulation offers resistance to scratches, impact, detergents, and solvents, making it ideal for residential and commercial interiors such as bathrooms, kitchens, spa areas, corridors, and living spaces. Top 2K is suitable for a wide range of substrates including cement-based coatings, lime plaster, painted surfaces, and even slightly damaged finishes.

Mix Component A and Component B thoroughly using a mechanical mixer before application. Two coats are recommended, with a four-hour drying time between them and a 24-hour cure period to complete the system.

Step 4 of the 4-part OLTRE Microcement System, Top 2K locks in the aesthetic while delivering long-term surface protection.
