About Mor-Flexx

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.
How to Use Mor-Flexx
The most important step for a successful Mor-Flexx repair is to make the surrounding area as clean as possible – that means removing all loose and foreign matter with a thorough wire brushing, even if it looks "clean."

Substrate Preparation

  1. If dirt or oils are present, wash with any household cleaner, rinse to remove and allow to dry.
  2. Wire brush the crack or chipped area (or use a drill with a wire wheel) to loosen and remove any poorly bonded material, and to provide good surfaces for adhesion. Use a vacuum cleaner (intake or exhaust), compressed air, or a wet rag or sponge to completely remove all loose material and dust.
  3. If crack depth is greater than 1" (25mm), appropriate size backing rod may be inserted to about 3/8"-1/2" (10-13mm) below surface for a stronger, longer lasting seal that actually uses less Mor-Flexx.


Application

  1. Insert cartridge into a standard 2" caulk gun, cut nozzle to desired opening.
  2. Gun Mor-Flexx into the crack and work it into the sides with a scraper or other tool for complete sealing and adhesion; repeat until filled.
  3. Smooth out exposed filled area with a foam paintbrush, sponge or scraper, making it flush with the joint.
  4. Natural shrinkage will give the seal a concave appearance; more applications may be needed to fill the joint flat.
  5. If painting is desired, wait at least one day after the last application.
  6. Clean-up tools and hands with warm water and soap.
  7. Leftover Mor-Flexx can be stored if the nozzle is tightly wrapped with plastic wrap and a rubber band.


Helpful Application Tips

Mor-Flexx, and all water-cleanup products, cure by water evaporation. Temperatures below 40°F, humidity higher than 50%, no direct sunlight, and the size of the filled area can all affect the time Mor-Flexx needs to fully cure. Mor-Flexx can be applied in damp areas, but should not be exposed to rain until cured. Alcohol and/or water in a spray bottle may be used to slow skinning (the initial drying of the exposed joint area) above 70°F (21°C) or in hot, direct sunlight.
