Grundix BetonContact Acrylic Primer

Grundix BetonContact is a high-performance, ready-to-use acrylic primer designed specifically for challenging substrates. It acts as a critical bonding agent, ensuring a strong and durable connection between smooth, low-absorption concrete surfaces and subsequent gypsum plaster or finishing layers. By sealing the concrete, it prevents the rapid absorption of moisture from the plaster, which can otherwise lead to weak bonds, cracking, or delamination.

Key Features

• Excellent Adhesion: Creates a uniform, porous surface that significantly improves the mechanical grip of gypsum plaster.
• Solvent-Free Formula: Eco-friendly and safe for indoor application, with no harsh odors or volatile organic compounds (VOCs).
• Ready-to-Use: No dilution required, ensuring consistent performance and ease of application.
• Fast Drying: Allows for quick progression to the next stage of plastering or finishing.

Applications

Ideal for use on smooth concrete walls, ceilings, and structural elements prior to applying gypsum plaster, cement-based renders, or decorative finishes. It is particularly effective in new construction and renovation projects where the concrete substrate is too dense or smooth for standard plaster to adhere properly.
