Mor-Flexx™ Won't Re-crack
Have you tried other mortar, stucco and grout repair products that cracked again because they dried hard and brittle? Mor-Flexx is different - it stretches and 'flexes' with temperature change and movement yet still has the sandy texture and color of mortar. You'll get a stretchy seal that lasts for years.

What Does Mor-Flexx Fix?
Use Mor-Flexx to repair interior and exterior cracks or gaps in:

  • Mortar
  • Stucco (including edging)
  • Artificial Stucco
  • EIFS (Exterior Insulation Finishing Systems)
  • Concrete foundation sidewalls and basement floors
  • Grout in tile floors and countertops
  • Textured walls and ceilings.

Where NOT To Use Mor-Flexx

  • Mor-Flexx should NOT be used on concrete less than 6 months old; the concrete is not fully cured.
  • Mor-Flexx should NOT be used where hydrostatic resistance is wanted (an example of hydrostatic resistance is sealing a crack in a basement foundation wall that will be exposed to water and the pressure the water exerts on the joint).
  • For the longest lasting seals, Mor-Flexx is not recommended for use on horizontal surfaces like driveways and sidewalks, or any surfaces that are continually wet.
