Great Product!

Bought this product to repair cracks in the stucco of my garage walls. It worked great-easy to apply and the results are amazing. Highy recommend

Two Thumbs Up!

This was my first time to try Mor-Flexx. I had some crumbling mortar between the cinder blocks of the front porch that I wanted to patch without doing major reconstruction. This product made the job quick & easy. I broke away the old mortar then swept it hard with a stiff-bristle brush. I snipped the tip of this mortar repair and squeezed it into the necessary spots. Last I used a putty knife to give the application a smooth finish. As it cured, the new material dries in a slightly concave way, ...

Fast & easy

matched my stucco perfectly... holds up well too. I had some 1/2” stair-step cracks that i filled with backer rod, and this did the job perfectly.

Easy to use, durable & matches the original mortar

This mortar repair caulk was a perfect color match to the original mortar between the stones on our house and fireplace. It’s really easy to use for both narrow little cracks as well as wide gaps. Both color and texture look like the original mortar. I first used a tube of it about 6 years ago for cracks caused by settling foundation and those repairs have held up perfectly.

Great Product

White painted Brick. Covered 1/8 to 1/2 gaps in mortar well. Super texture perfectly matched mortar. Held paint well. Flowed really well. Just the right consistency to flow but not run. So far no shrinkage overnight. Highly recommended product.

Great concrete crack repair

Works well filling cracks in concrete, which if you have concrete, you have cracks.

Works like mortar.

Fills in lost mortar in bricks well.

Easy and effective

Easy to put on, smooths out well and doesn’t chunk and fall off.

Hard to get out of tube. Cut a large opening.

Works as described. Thinner than morter but flexable.

It’s not grey

The product works well. I used glass cleaner on my fingers as recommended and it was easy to tool. It filled and covered well and the texture is good for motar repairs. The only issue and it’s a big one for this type of repair is the color. It’s more tan than grey and is not a good match for typical brick motar. I would not use it again as the repair area stands out.
