When applied to mat damp concrete, brush the adhesive well into the substrate.
Pot Life
| Temperature | Potlife | Open time |
| +25 °C | ~90 minutes | ~120 minutes |
| +55 °C | ~30 minutes | ~60 minutes |
The potlife begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the potlife. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill components A+B before mixing them (not below +5 °C).
SUBSTRATE QUALITY
See the Product Data Sheet of Sika® CarboDur® Plates and Sika® CarboDur® BC rods.
SUBSTRATE PREPARATION
See the “Method Statement for Sika CarboDur® Externally Bonded Reinforcement” Ref: 850 41 05 and the “Method Statement for Sika CarboDur® Near Surface Mounted Reinforcement” Ref: 850 41 07.
MIXING
Pre-batched units:
Mix components A+B together for at least 3 minutes with a mixing spindle attached to a slow speed electric drill (max. 300 rpm) until the material becomes smooth in consistency and a uniform grey colour. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its potlife.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
