Spray Technique & Pass Control

The gun is in your hands. This is where good foam lives or dies.

We start with lift height and pass speed — the two variables that decide whether your foam cures flat and to-spec or lifts, splits, and traps air.

Then overlap and pattern: how to read the foam as it lays down, adjust on the fly, and keep thickness consistent across a wall or roof deck.

We cover substrate prep and temperature: spraying onto metal, wood, concrete, and existing materials, and how surface temp changes everything.

We finish with troubleshooting: off-ratio foam, blisters, poor adhesion, and what to do the moment you see it — including when to stop and cut it out.

By the end you'll spray with control, not hope.
