Primer G - Versatile Synthetic Resin Primer for Surface Preparation

Enhanced Adhesion: Improves bonding of smoothing compounds and adhesives on cement, gypsum, asphalt, ceramic, and marble surfaces.
Surface Consolidation: Dries to form a flexible, compact, shiny coating that strengthens porous or friable substrates.
Low VOC Content: Water-based dispersion with very low volatile organic compounds, ensuring eco-friendly application.
Versatile Applications: Ideal for treating gypsum or anhydrite surfaces before tiling, as a fixative for wallpaper adhesives, or as an anchoring coat for sprayable plasters.
Uniform Absorption: Regulates substrate porosity to ensure consistent adhesive performance and prevent uneven drying.
Easy to Apply: Liquid consistency allows for quick application with a brush, roller, or spray, suitable for both interior and exterior use.

Product Overview

Primer G is a high-performance, synthetic resin-based primer in water dispersion, designed to prepare a wide range of surfaces for tiling, levelling, or plastering. With its low viscosity and excellent penetration properties, it creates a robust, flexible coating that consolidates weak or dusty surfaces while enhancing the adhesion of subsequent layers, such as self-levelling compounds, thixotropic smoothing compounds, or tile adhesives. Perfect for residential, commercial, and industrial projects, Primer G is particularly effective for treating gypsum, anhydrite, or cementitious substrates prior to installing ceramic tiles, stone materials, or wallpaper. Its low VOC content ensures compliance with environmental standards, making it a sustainable choice for modern construction.

Key Benefits:

Improved Bonding: Enhances adhesion on challenging substrates like gypsum, anhydrite, and non-absorbent surfaces.
Surface Strengthening: Consolidates porous or friable surfaces, reducing the risk of failure in tiling or plastering applications.
Eco-Friendly: Low VOC formulation minimizes environmental impact and ensures safe indoor use.
Time-Saving: Quick-drying formula allows for faster project progression, with smoothing compounds or adhesives applicable after drying.
Wide Compatibility: Suitable for use with ceramic tiles, stone materials, gypsum-based plasters, and wallpaper adhesives.

Application Guidelines:

Apply to clean, dry surfaces free of dust, grease, or loose particles.
Dilute with water based on substrate porosity (e.g., 1:1 for gypsum, 1:2 for cementitious surfaces).
Use a brush, roller, or spray for even application; ensure complete coverage without pooling.
Allow to dry fully before applying smoothing compounds, adhesives, or plasters.
Recommended for preparing surfaces in bathrooms, kitchens, and exterior areas before tiling or plastering.
