Sashco’s Slab vs. Mor-Flexx: Which is the Best Concrete and stucco Repair Caulk?
It can be confusing to choose the right caulking product when they have a lot in common.
Say you have a concrete crack in your sidewalk, and a crack in your stucco near a window. Sashco makes two great products, both made for these textured surfaces. So which one should you use?
The answer is both.
Yes, Sashco’s Slab® and Mor-Flexx® have some similarities:
- They’re both for textured surfaces.
- They’re both easy to apply.
- They’re both easy to clean up with water.
- They’re both safe through 10 freeze-thaw cycles when unopened.
- They both come with a Limited Lifetime Guarantee.
- They both have really cool names (even if we do say so ourselves).

Can I use Slab in place of Mor-Flexx? Or Mor-Flexx in place of Slab®?
You can use Slab wherever Mor-Flexx is used, but it may not match as well. For better overall aesthetics, opt for Mor-Flexx.
In response to the second question, no. Mor-Flexx is not designed to hold up to foot and vehicle traffic.
