Viero OLTRE Microcement | Step 2. Barrier (Waterproofing)

Viero OLTRE Barrier is a ready-to-use waterproof skim coat designed to create a reliable moisture barrier as part of the OLTRE seamless decorative wall and floor system. Applied after the Base primer (Step 1), this product plays a vital role in ensuring the system’s durability and water resistance, particularly in wet environments like bathrooms, kitchens, spas, and poolside areas.

Suitable for use on walls, ceilings, floors, and even heated surfaces, Barrier helps prevent water penetration beneath the surface layer. It is especially effective when used in conjunction with waterproof mesh and is applied in two coats, starting with corners and junctions, to establish a fully sealed system.

Step 2 of the 4-part OLTRE Microcement System, this waterproofing layer ensures long-term protection and performance in moisture-prone environments.

Key Features:

• Waterproof Protection: Creates an impermeable layer to guard against moisture and humidity.
• Ready to Use: Pre-mixed and easy to apply with a trowel or spatula for professional results.
• Suitable for Multiple Surfaces: Ideal for walk-on floors, ceilings, and underfloor heating systems.
