Sashco - FLX-P-GR-12 15020 Mor-Flexx Caulking for Mortar, 10.5 Ounce Cartridge, Gray (Pack of 12)

I used around windows , was easy to work with and to clean as long as the outside Temperatur is not to high

worked out great clean-up as expected for this kind of stuff.

Grey or tan usually matches (close enough) existing wall color & texture helps blend in... so usually painting isn't necessary

Mor-Flexx is great. This is the grey option and there also is a beige. For horizontal cracking there also is a product called slab which has finer grit and is a little darker grey. I do a lot of caulking and having finally found the Sashco line of caulks just over a decade ago I can assure you they are absolutely the best, most long lasting and durable caulking materials. Other caulks often failed in under a year and, to boot, often ended up looking worse than the cracks filled in a relatively short time. The essential key around which all of this caulk line is allowing for stretch. OK the names may be too cute but that doesn't stop them from unparalleled performance. I use this caulking for well beyond what is recommended on-label (spaces too big, etc.). All caulking I have used before taking up the Sashco line of caulking was just wasting my time and spending money wastefully... if one has any concern for lasting durability.

A really nice product. Looks great, easy to apply and cleanup. Used for small to large gaps in stucco, on the large gaps used foam backer first - turned out better than expected.

Great product we use on tile roof mortar connections and mortar to wall flashing the most for over 15 years and never failed us

Good Product. Works as stated. Takes paint well for a perfect match if you need to darken the color a little. More of a tannish grey than a true grey so looks very much like mortar both in color and texture.

this stuff is awesome! Does what it says and looks great!

As described....works perfectly!
