Sika® Hibond

Structural bonding agent between old and new concrete

Epoxy based, two component structural bonding agent. Sika® Hibond compiles with ASTM 881 – 87 Type II Grade 2 Class B and C.

  • Long pot life and open time allows sufficient time for placement of new concrete
  • Can be applied on moist surface also
  • Once the two components of the material is mixed the material must be used within approx 4 hours.

Application

Application Information

Pot Life

(According to FIP 5.1)

Temperature

Sika® Hibond

300 C

4-5 hours

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 parts A+B before mixing them (not below +5°C).
Consumption

Consumption

1pack of 600g covers approximately 12-30 sqft depending on roughness and porosity of substrate

(0.200- 0.500 kg/sqm depending on roughness and porosity of substrate)
Application steps

SUBSTRATE QUALITY

Mortar and concrete must be older than 28 days (dependent on environment and strength).

Verify the substrate strength (concrete, mortar).

The substrate surface (concrete, mortar) must be clean and free from frost standing water.

Concrete substrate must be sound and all loose particles must be removed.

SUBSTRATE PREPARATION

Concrete, mortar:
Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loosely adhering particles to achieve a laitance and contaminant free, open textured surface. Cement laitance must be removed and the surface to be treated must be mechanically roughened


Steel:
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by wire brushing, blast cleaning or vacuum.

MIXING

Part A : Part B = 2 : 1 (by weight) Prebatched

Mixing Time

Pre-batched units
Mix parts A+B together for at least 3 minutes with the provided spatula 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 TOOLS

Clean all tools and application equipment with Sika® Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
