The concrete substrate must be sound and of sufficient compressive strength (~25 N/mm2) with a minimum pull off strength of 1.0 N/mm2.
The substrate must be sound, clean, dry, free from contaminants such as dirt, grease, oil, old coatings, release agents, laitance and other adhesion preventing or influencing substances.
On high absorbent, non-sound, contaminated, not cement based substrates precautions have to be taken and a suitable primer has to be used.
Concrete substrate must be prepared mechanically to achieve an open textured surface.
Weak areas in the substrate must be removed and surface defects such as blowholes and voids must be fully exposed.
All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum.
Open voids and blowholes need to be closed with a suitable Sika® pore filling mortar. The roughness of the substrate needs to be levelled with a suitable Sika® rendering and levelling mortar.
Steel surface must be prepared mechanically using abrasive blast cleaning. The level SSPC-SP 10 “near white metal blast cleaned” or level Sa 2 ½ according to ISO EN 12944-4 has to be achieved. Welds and joints have to be prepared according to EN 14879, part 1. After blast cleaning remove all dust dirt and blasting material. In order to maintain the surface conditions after blast cleaning air-conditioning is recommended.
Prior to mixing stir part A mechanically. When all of part B has been added to part A mix continuously for 3 minutes until an uniform mixed has been achieved. Use a low speed electrical stirrer (300 - 400 rpm) to avoid air entrapment. To ensure proper mixing pour material into a clean container and stir again.
Apply by brush, short piled roller or airles spray.
CLEANING OF EQUIPMENT
Clean all tools with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
