Concrete surfaces

• Self-priming application, MegaFilm A901, A501 or BB A204 primers

Metal surfaces

• MegaFilm A502 primer

Surface Preparation

• The surface must be dry, clean, sound and free from dust.
• Surface defects larger than 1 cm should be repaired with MegaTamir T101/T102, while structural repairs should be carried out with MegaTamir T103/T104.
• Corner joints should be rounded or reinforced with Megaİzo Tape S901.
• Gaps around drainage points should be filled with MegaTamir Grout T105/T107.
• Expansion joints should be formed on large surfaces, and Megaİzo PU Mastic HM S492 should be used for movement joints.
• If surface moisture exceeds 20%, MegaFilm İzo Epo A501 primer should be applied.
• On absorbent cement-based surfaces, the product can be diluted with 20% water and used as a primer coat.
• MegaFilm A502 primer should be used on metal surfaces, and BB A204 primer should be preferred on exposed concrete surfaces.

Application Method

• The product is ready to use. Before application, it should be mixed with a low-speed mixer until a homogeneous consistency is achieved.
• Apply a minimum of 2 coats. Under low-temperature or high-humidity conditions, 3 coats are recommended.
• Each coat should be applied perpendicular to the previous coat.
• Dry film thickness: 2 mm
• Application temperature: +5°C to +35°C
• Application equipment: Roller or airless spray machine
