Sikaflex® Mortar Fix

One-component, Textured, POLYURETHANE SEALANT FOR SEALING MORTAR CRACKS/JOINTS

Sikaflex® Mortar Fix is a moisture-cured, 1-component, polyurethane-based, non-sag elastomeric sealant. Meets Federal specification TT-S-00230C, Type II. Meets ASTM C-920, Type S, Grade NS.

  • Excellent adhesion – bonds to most construction materials without a primer.
  • Textured appearance blends well to rough or stucco type surfaces.
  • Hides imperfections from tooling that a smooth sealant does not.
  • Excellent resistance to aging, weathering
  • Non-staining
  • High elasticity – cures to a tough, durable, flexible consistency with exceptional cut and tear resistance.
  • Stress relaxation
  • Urethane-based; suggested by EPA for radon reduction
  • Paintable with water-based, oil-based or rubber-based paints

Usage

  • Designed for all types of joints where maximum depth of sealant will not exceed 1/2 in. (12.7 mm).
  • Suitable for vertical and horizontal joints; readily placeable at 40 °F (4 °C).
  • Has many applications as an elastic sealant between materials with dissimilar coefficients of expansion.
   Ideal for:
  • Weatherproofing of joints between brickwork, blockwork, masonry, concrete or metal frames
  • Joints in walls, balconies, around window or door frames
  • Expansion joints
