MITECH MG - Deep Penetrating Primer for Mineral Substrates - 5kg

MITECH MG is a deep‑penetrating, water‑based primer designed to strengthen and stabilise absorbent, chalking and weak mineral substrates prior to the application of adhesives, base coats, renders and façade paints. It improves substrate cohesion, regulates absorbency and enhances the adhesion of subsequent layers within the MITECH thermal‑insulation system.

MITECH MG penetrates deeply into porous mineral surfaces, binding loose particles and reducing excessive absorbency. This creates a uniform, stable base for ETICS adhesives, levelling mortars and thin‑coat renders. The primer is colourless, allowing easy visual control during application, and is suitable for both new‑build and refurbishment works. It is recommended for substrates such as cement render, lime‑cement render, concrete, masonry and old, absorbent coatings that require consolidation before further treatment.

Consumption: ~0.1–0.2 l/m² depending on absorbency

CHARACTERISTICS

• Deep penetration — strengthens weak, dusty or chalking mineral substrates.
• Improves adhesion — enhances bonding of adhesives, base coats and renders.
• Regulates absorbency — ensures uniform drying and consistent finish.
• Colourless formulation — easy to monitor coverage on site.
• Fast drying — enables efficient workflow in ETICS installations.
• Compatible with MITECH ETICS — ensures system performance and durability.

APPLICATION

• Strengthening weak mineral substrates before ETICS adhesives
• Priming absorbent renders prior to thin‑coat render application
• Preparing surfaces for façade paints
• Renovation of chalking or dusty coatings

MITECH MG provides reliable substrate consolidation, improved adhesion and controlled absorbency, ensuring stable performance of subsequent ETICS layers. Its deep‑penetrating action makes it a trusted choice for preparing challenging mineral surfaces in both new and existing buildings.
