PRODUCT INFORMATION:

BASIS OF PRODUCT DATA:

All technical data stated in this Product Data Sheet are based on laboratory tests. Actual measured data may
vary due to circumstances beyond our control.

ECOLOGY, HEALTH AND SAFETY:

For information and advice on the safe handling, storage and disposal of chemical products, users shall refer to the most recent Safety Data Sheet (SDS) containing physical, ecological, toxicological and other safety-related data.

APPLICATION INSTRUCTIONS:

SUBSTRATE QUALITY

Substrates must be sound, clean, free from oil and grease, old coatings and surface treatments etc.

SUBSTRATE PREPARATION

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:

• 1. 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:

IMPORTANT

• Part mixing is recommended.
  Add both parts in the correct proportion into suitable clean and dry container, mix in the same way as for the pre-batched units.

APPLICATION:

Impregnation of cracks in horizontal planes: Saturate the crack by applying the product by paint brush or roller in several passes or by pouring between two “barriers” made with Sikaflex sealant. The crack penetrating through structure must be sealed on the underside with Sikadur 31 IN epoxy mortar or a suitable Sika® cementitious mortars.Injection of cracks on horizontal / vertical planes:
Sikadur 55 LP IN can be injected under pressure into cracks using a single-component injection pump. The injectors should be placed at a distance of 25 cm and
the fissure between sections of injectors should be superficially sealed with Sikadur 31 to avoid the loss of resin during the injection process. Vertical cracks must
be injected from the bottom up. As soon as the resin oozes through the next injector, the first must be sealed and continue the injection process from the next. After completing the injection process, the injectors and sealing material can be removed.IMPORTANT
Maximum width of cracks to be injected: 5 mm. Please contact Fortimix Construction Technical Services for cracks > 5 mm. Facebook Page Visit

CLEANING OF EQUIPMENT:

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