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
- If dirt or oils are present, wash with any household cleaner, rinse to remove and
allow to dry.
- 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.
- 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
- Insert cartridge into a standard 2" caulk gun, cut nozzle to desired opening.
- 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.
- Smooth out exposed filled area with a foam paintbrush, sponge or scraper, making
it flush with the joint.
- Natural shrinkage will give the seal a concave appearance; more applications may
be needed to fill the joint flat.
- If painting is desired, wait at least one day after the last application.
- Clean-up tools and hands with warm water and soap.
- 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.
