MCG Primer
A reliable foundation for cement-based finishes
MCG Primer is a water- and polymer-based primer that enhances adhesion and durability for cementitious finishes on a wide range of surfaces.
- Extremely easy to apply, ready to use
- Optimises surface adhesion for cement-based systems
- Suitable for both residential and commercial surfaces
MCG creates a consistent surface by improving density and bonding power. Prepares the substrate to maximise performance and longevity of cement-based products.
Use it straight from the can or dilute up to 300% for highly absorbent surfaces. Ideal for floors, walls, and a variety of mineral surfaces.
A primer engineered for professional results. Seals and stabilises surfaces for long-lasting finishes.
Available in 1L and 5L jerrycans, ready to use. Apply with roller, brush, or sprayer—no extra steps needed.
MCG Primer is ready to use and can be applied undiluted on most surfaces. For highly absorbent substrates, it may be diluted up to 300%. Apply evenly with a foam roller, microfiber roller, block brush, or airless sprayer. Always ensure the surface is clean, dry, and free of dust before application.

System setup
MCG Primer is the essential first step in any cement-based finishing system. It ensures optimal adhesion, stabilises absorbent substrates, and improves the overall density of the surface. Used as a base layer before applying decorative products like Basebeton or Beton Ciré, MCG helps prevent uneven absorption and surface failures. For a complete and high-performance finish, follow with a cement-based coating and seal with SA Omni Shield for long-term protection.
