Hello, everyone. This is Enta.

Adding color pigment to sprayed mortar to color it can reduce its strength, cause uneven coloring, and may eventually lead to it crumbling.
Hello, everyone. This is Enta. Are you all okay there in the Tohoku region? The destructive power of that linear rainband is unbelievable! Please be very careful! But anyway, when we color slope surfaces, we usually add color powder (iroko) (if it’s included in the design). Magnesium oxide…
"1.24 m³ of sand for sprayed mortar work?" (Regarding the mix design)

The application rate for mini-crate spraying depends on the pump size | Machinery
Hello, everyone. This is Enta. The other day, for the first time in a while, I did some spray application and Mini-Crete spraying on a small lot. On Saturday, I asked them to bring some mortar that was a bit stiffer—and what showed up was dry-mixed mortar! As expected, there’s just no way to work with dry-mixed mortar using this equipment lol. Straight from the ready-mix truck…
Thoughts on the Cross-Section of a Sprayed Mortar Worker | Analysis
