APPLICATION INSTRUCTIONS

SUBSTRATE QUALITY

  • The surface to be treated must be structurally sound, free from standing water, oil, grease, surface contaminants.
  • Minimum age of concrete must be 21 - 28 days, depending on curing and drying conditions.

SUBSTRATE PREPARATION

  • Concrete, mortar, stone should be thoroughly prepared.
  • Dirt, dust and other foreign materials must be removed by high pressure water jetting or mechanical means such as grinding, chiselling etc.
  • Concrete which is fully contaminated with oil / grease, must be removed to the depth of sound & uncontaminated concrete.
  • Cracks must be cleaned to remove dust with compressed air.

MIXING

Neat resin or primer

  1. Weigh the resin (comp. A) and hardener (comp. B) part as per mixing ratio (by weight) and mix together for 3 minutes at slow speed (400-500 rpm) with a mixing spindle attached to an electrical drill.
  2. Continue mixing until the material becomes uniform in colour. Avoid aeration while mixing. Mix only that quantity which can be used within its pot life. 

  

Mortar system

  1. To prepare an epoxy mortar slowly add 5 parts by weight of filler (comp. C) to 1 part of mixed Part A + Part B and mix until uniform in consistency.

APPLICATION

Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.

  

IMPORTANT

Sikadur®-55 SLV IN is not designed for injection / impregnation of cracks under hydrostatic pressure at the time of application.

IMPORTANT

Do not seal exterior slabs on grade.

  

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 SLV 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 Sika Technical Services for cracks > 5 mm.

  

Mortar Application

  1. Prime prepared surface with mixed Part A & Part B of Sikadur®-55 SLV IN.
  2. Place prepared epoxy mortar before primer becomes tack-free using trowels.
  3. Finish with finishing trowel.

IMPORTANT

Maximum epoxy mortar thickness is 25 mm per layer.

CLEANING OF TOOLS

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