Mor-Flexx Textured Caulk, Gray, 10.5 oz (Pack of 1)

I am a DIY-er of old homes and recently exposed the brick that was hidden behind my plaster walls. Unfortunately, that brick is not always preserved as well as one would like. That's where MorFlexx shines. It fills in mortar cracks and becomes almost invisible after installing. I tried several different products and only Morflexx matched the mortar color. Installation is as easy as caulking (use rubber gloves but evenso, cleanup is easy) - it is simple to work with and adheres well. It dries quickly (pretty much the same as caulk). And finally, the price is almost negligible for the quality and quantity you get. After install, don't forget to seal the brick with something like Thompson's.

I love this stuff! I've used stucco patch in the past, and the results have mostly been "not great." First of all, the grittiness is never perfect, so the smoother surface sticks out like a sore thumb. Then it's hard to work with and takes a while to cure. And if the damage is caused by anything reoccurring, it just comes back, only now it looks patchy AND damaged. I figured this was a job better left to the professionals, but the professionals want a lot of money for this sort of work. After watching youtube, I bought this to fill a crack in a stucco retaining wall that just snapped through the stucco patch. and seriously? You can't tell it was there. Not even months later. It's like magic. Since I had plenty left over so I used it to patch the damaged stucco under the front door. Not only does it look perfect, but because of the rubbery texture, I dont have to worry about it cracking and cumbling again. This has no doubt saved me hundreds on those two places alone, but I had plenty left over. I smeared some over the parts I repaired with stucco patch and repainted. Much better! I just used up the last of it patching small holes in the stucco retaining wall. It is perfect for that, since you just pipe into the hole and it works like glue, saving as much of the surface as you can. The rest you just rub or slap until it matches the surrounding texture. It's child's play. I'm almost tempted to fix the whole neighborhood.

This product matches gray stone veneer, concrete, faux stone & any other rock based product so good you'll look like a mason. 100% recommend.

This is a great product, stays flexible holds up to wet weather. Looks great. Easy to work with. Just make sure you allow recommended dry time before exposure to long hard rain.

Pros: Durability – I used this to fill some small gaps between the bricks on my house, and it performed really well. It seals fast, holds firmly, and feels as strong as the mortar I blended it with. Ease of Use – Very easy to use. I recommend applying it with a caulk gun. I used the gun to get the grout out, placed it in the mortar joints, smoothed it with a wet cloth, and then used my finger to blend it in. That method worked best for me. Appearance – Not noticeable unless you know where to look. Quality – The quality is great. The grout is smooth, malleable, and blends in nicely. I would definitely buy this again, even though I gave it four stars. I just think the color could be a bit more accurate since mortar is generally a universal gray. Cons Color – The gray is lighter than average mortar, but it will probably blend in with a bit of weathering. It’s not noticeable unless you know where to look.

I use this in application and like many of their other seals it worked absolutely as it should. I will not use another brand for wood or concrete caulk.

Excellent product for repairing chipped/broken mortar.

This has been a solid product to repair the chinking on our steps. I would be sure to give it a few days or more to cure with no rain, or it will not do well. I need to go over it at least twice to fill in tiny holes because it doesn’t leave a smooth surface. The grout gun will require a lot of pressure! This pic is a few months old. Clearly I’m procrastinating finishing the project.

Great product, easy to use and looks neat and very discreet.

Had a problem with the regular grout .. We haul wood into our kitchen and have 24" ceramic tiles . The floor comes under stress from the weight and moves , ever so slightly .. So every year or so we have tiles that the grout cracks and gets removed . I typed in "flexible grout" and this product came up on Amazon . Works great , easy to use , cleans up easily and came in grey which matched the rest of the floor . Several months now and no cracks ! Highly recommend .

I’ve just applied this product to fill a long vertical crack in the mortar between the exterior bricks. It applied really well but is lighter than the mortar on my home. It appears more light beige than gray. To give an honest opinion whether it holds or not I’ll have to wait and see so I cannot give that information at this point. Time will tell.

Honestly, worth the investment. The best product to fix cracks in stucco.

I used this product to fix a gap left between transition piece and tile following carpet installation. Was a good match for my tile grout .The tiles were installed about 20 years ago so i was pleased with the colour match and the gap is filled nicely.
