Great results for a first time user setting cap stones on a concrete block retaining wall
We recently built a retaining wall out of concrete blocks. While we used construction adhesive to bond the concrete blocks together, we made the cap stones from natural sandstone and cemented them to the top of the wall using this masonry mortar.
Despite it being the first time I've ever done a masonry job, I found that this was very easy to mix by hand with a small shovel to a consistency I was comfortable working with. Even though it was almost 100 degrees on the day I was installing the cap stones on the wall, the mixed mortar stayed workable for quite a while, allowing me to mix it up in smaller batches as I needed it. I mixed it a little wetter than I needed since it was a very hot day and then let it sit for 5 minutes or so before giving it one more mix with the trowel. I also found that I could keep the unused mix in good useable shape by misting it with water from a pump sprayer if it was getting too dry from the heat.
When laying the cap stones, I sprayed the top of the wall with some water before applying the mortar and then scooped out a 'V' down the middle with the trowel tip. I set the sandstone on top and used a rubber mallet to gently tap it into the mortar and ensure it was level. The mortar set up well and there was quite a good suction even when the cap stones were first set while the mortar was still wet. A day
later the cap stones were solidly set.
Clean up was also easy - In places where the mortar had dropped onto the rough face of the concrete blocks, I just sprayed it with water from the pump sprayer after I set each cap stone (before the mortar had a chance to dry) and brushed it with a nylon nail brush and then sprayed it with water again to stop the light grey mortar from staining the brown colored blocks.
I also mixed in some small stones and sand with the mortar in a small batch to help me make up for a shortfall of concrete when I was laying the foundations and it worked very well for this too.

Delivery people should be fired. I will never purchase a product at Home Depot and have it delivered to the job site, I can’t tell you how bad they conduct business. This is the 2nd delivery this year both a disaster.
Contact with Home Depot employee's was a 10 on the 10 scale. They solved the problem.
