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, chiselling 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:
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 55 LP IN price in Bangladesh epoxy mortar or a suitable Sika® cementitious mortars.
Injection of cracks on horizontal / vertical planes:
Sikadur 55 LP IN price in Bangladesh 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 Sika Technical Services for cracks > 5 mm.
CLEANING OF TOOLS
Clean all tools and application equipment with Sika® Colma-Cleaner immediately after use. Hardened or cured material can only be mechanically removed.
