Sikadur-33 serves as a structural adhesive for materials such as concrete, hard natural stone, ceramics, fiber cement, mortar, brick masonry (both hollow and solid), steel, iron, and wood. It is also suitable for small concrete repairs, including corners, edges, hole and void filling, and joint arrises.

APPLICATION

Equipment

  • 250 ml Cartridges: Require a standard, keyed action applicator gun.
  • 400 ml Cartridges: Require a 1:1 ratio side-by-side applicator gun with a thrust ratio of 26:1 (available from Sika).

Substrate Quality

  • Concrete, Masonry, Mortar, Stone: Substrates must be at least 28 days old, sound, clean, and either dry or matt damp but free from standing water. Remove contaminants like oil, grease, coatings, laitance, and loose material.
  • Steel: Surfaces must be sound, clean, dry, and free of dirt, oil, grease, coatings, and loose particles.
  • Wood: Surfaces must be sound, clean, dry, and free of dirt, oil, grease, coatings, and loose particles.

Substrate Preparation

  • Contaminant Removal: Dust, loose particles, and contaminants can reduce performance. Use vacuum or dust removal equipment to clean all surfaces thoroughly.
  • Concrete, Masonry, Mortar, Stone: Prepare the surface mechanically using abrasive blast cleaning, needle gunning, scabbling, bush hammering, or grinding to achieve an open-textured, gripping profile.
  • Steel: Use abrasive blast cleaning, wire brushing, or grinding to create a bright metal finish with a suitable surface profile.
  • Wood: Prepare using planing, sanding, or other suitable methods.

Mixing

  1. Unscrew and remove the cartridge cap and plug.
  2. Attach the static mixer nozzle to the cartridge.
  3. Insert the cartridge into the application gun.

Application

  • General Instructions:
    • Confirm dew point conditions before and during application.
    • Pump until both components are extruded as a single, consistent color.
    • Discard any inconsistently colored product.
    • Apply the product using a specific application gun.
    • For heavy vertical or overhead components, provide temporary support until fully hardened.
    • Immediately clean tools with Sika® Thinner C and wash hands thoroughly with warm, soapy water.
  • Bonding:
    Apply adhesive to both surfaces for optimum adhesion. Position heavy components with temporary support until the product hardens.
  • Repair:
    Apply to the prepared substrate and finish the surface with a spatula or trowel as needed.
  • Joint Filling and Crack Sealing:
    Apply the product to the prepared joint or crack and tool the surface for a smooth finish using a spatula.
