Use a continuous-feed mortar/stucco spray pump to apply an even coat of plaster or stucco across an entire exterior wall dramatically faster than a manual trowel crew, subcontracting to general contractors on new suburban home builds.
Charges $4-8 per square meter of wall coverage; a standard new home with 400-600 square meters of exterior wall at $6/meter works out to $2,400-3,600 gross for a job completed in about 2 days, appealing to contractors given how hard skilled manual plaster crews are to find.
Someone willing to learn the spray technique and market directly to general contractors building new housing subdivisions.
Mortar/stucco spray application is a real, established time-saving trade technique addressing genuine skilled-labor scarcity. The per-job math shown is a straightforward calculation from stated rates, not a claimed personal result.
