Great mortar caulk!
Would RecommendThis works very good to point up mortar joints that are missing mortar.
Way easier than mixing mortar for small cracks
Would RecommendWent on easily, and looks close enough to mortar when it drys to make it worth the cost of the tube.

Great caulk for mortar joints & concrete cut lines
Would RecommendBest caulk I have found for cosmetic repair of mortar between bricks, limestone caps and concrete cut lines on driveway. Easy to work with and can clean edges with wet rag if doing highly cosmetic repairs.

I installed a new exterior door with stucco molding, I used this to fill the gap between molding and stucco, taped off the molding and squeezed it into the gap, finished it with my finger by wiping it toward the stucco. It blends in really good, after painting, it should be invisible. Great product.
