Substrate temperature must always be at least 3°C above the dew point.

Min. 5°C - Max. 30°C

The concrete substrate must be sound and of sufficient compressive strength (min. 20 N/mm²) with a minimum pull off strength of 1.5 N/mm² .
The surface must be dry and free of all contaminants such as oils, grease, coatings and surface treatments etc.
The substrate must be prepared mechanically to remove cement laitance and achieve a profile open textured surface.
Weak concrete should be removed and surface defects such as honeycombed areas, blowholes and voids must be fully exposed.
Repairs to substrate, filling of blowholes/voids and surface levelling should be carried out using the appropriate product from the Sikafloor^®, Sikadur^® and Sikagard^® range of materials.

All surfaces must be clean, sound and properly cured. Remove all loose materials mechanically, with a wire brush, or by water or grit blasting.
Surfaces may be dry or damp, but must be free of any standing water.
Use mixed components Sikadur®-43 ZA (Components A & B) or Sikafloor^® 161 Primer to prime the substrate. On damp surfaces use Sikadur^® -31DW. Apply with a stiff brush and work in well.

Mix full kits only.
Mix component A thoroughly with component B for 1-2 minutes using a spatula, then add the aggregate (component C) and continue mixing with a slow speed mechanical mixer, until a homogeneous mortar is achieved.

Remove uncured Sikadur®-43 ZA from tools with Colma Cleaner immediately after use. Cured material can only be removed mechanically
