Schönox VD Universal Acrylic Primer

Schönox VD Primer is a high-performance, water-dilutable acrylic primer engineered to prepare porous substrates prior to the application of Schönox leveling compounds and underlayments. Available through 515 DCS, this versatile primer helps contractors improve adhesion, control substrate absorbency, and create a more predictable installation environment on both floors and walls.

Designed for use in interior and exterior applications, Schönox VD penetrates deep into porous surfaces, binding residual dust while promoting stronger mechanical and chemical adhesion between the substrate and subsequent underlayment systems. Its low-odor, solvent-free formulation makes it suitable for commercial, residential, and industrial flooring projects.

Why Contractors Choose Schönox VD Primer

Proper surface preparation is critical to the long-term success of self-leveling underlayments and flooring systems. Schönox VD helps:

• Reduce absorbency of porous concrete and cement-based substrates
• Improve adhesion before applying leveling compounds
• Bind residual surface dust
• Promote uniform drying and curing of underlayments
• Protect porous wood substrates from moisture migration
• Create a stronger bond on smooth, stable, and moisture-resistant surfaces

Its excellent penetration characteristics allow it to perform effectively on a wide variety of substrates while maintaining fast turnaround times for installation crews.

Recommended Applications

Schönox VD is ideal for:

Porous Concrete & Cementitious Substrates

Reduces excessive absorbency and improves surface consistency before applying self-leveling compounds and underlayments.

Existing Leveling Compounds
