Usage

  • Injection resin with good adhesion to concrete, mortar, stone, steel, and wood.
  • Used to fill and seal voids and cracks in structures such as bridges and other civil engineering, industrial and residential buildings, e.g., columns, beams, foundations, walls, floors and water retaining structures.
  • Effective barrier against water infiltration and corrosion promoting media.
  • Structurally bonds concrete sections together.  

Advantages

  • Solvent free
  • Suitable for both dry and damp conditions
  • Shrinkage free hardening
  • High mechanical and adhesive strengths
  • Hard but not brittle
  • Low viscosity
  • Injectable with single component pumps

+40 °C~10 min

The pot life 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 pot life. To obtain longer workability at high temperatures, the mixed injection resin may be divided into portions. Another method is to chill components A+B before mixing them (not below +5 °C).
Consumption

Consumption

1 kg of Sikadur®-52 LP AE is equal to ~1 L of injection resin
Application steps

SUBSTRATE PREPARATION

Requirements:
Substrates must be sound, clean, free from oil and grease, old coatings and surface treatments etc. Pre-treatment for good bond: Concrete, mortar, stone should be thoroughly prepared by high pressure water jetting or mechanical means such as grinding, chiseling etc. Cracks must be cleaned to remove dust by using compressed air.

MIXING

Pre-batched packaging:
Add all of Part B to Part A. Mix with an electric mixer at slow speed (max. 250 rpm) for at least 3 minutes. Avoid entraining air.
Bulk packaging:
Add both parts in the correct proportion into suitable clean and dry container, mix in the same way as for the pre-batched units.

 

CLEANING OF EQUIPMENT

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