Consumption
Theoretical coverage of 3.6m2 at 5mm thickness per 24 kg kit, depending on substrate profile and texture, waste factor etc.
SUBSTRATE QUALITY
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.
SUBSTRATE PREPARATION
Concrete Substrates
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
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.
MIXING
Prior to mixing stir part A mechanically. When all of part B has been added to part A mix continuously for 3 minutes until a uniform mix 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.
APPLICATION
Apply by brush, roller or airless spray.
CLEANING OF EQUIPMENT
Clean all tools with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
