The Four Hole Combination Model is built just like the Three Hole Model, except for one difference. The combination sprayers have a tilted spray head that enables you to apply concrete directly above your head. It comes with three holes, three small jets, three large jets, two jet plugs, and two hole plugs.
Introducing the Monolithic Quick Shot. This handheld shotcrete sprayer is easy to load, and has a surprisingly good throughput. We have used it to spray a number of small projects, where it's fast efficient design has saved us time and money. Its all steel construction means that it is long lasting, and will continue to be a good investment.
We are also glad to report that it also lays down a very smooth texture. The texture that it can produce, is similar to those of our larger shotcrete pumps and sprayers.
We recommend an air compressor that has a capacity of 7 c.f.m @ 90 p.s.i. You can go a bit lower, but you will have wait time in between hopper loads. Also, larger capacity air tanks will improve its ability to have consistent pressure.
