CF Sprayer

Fill it with construction foam in the Canning Machine (CF powder + water → foam, then fill). Holds 8000 mB and uses 100 mB per block. On a scaffold it replaces the connected scaffolds; on anything else it sprays a layer of 13 blocks. Foam can be walked through and hardens with light (at light 15, about 4 minutes; in the dark, never); sand hardens it instantly. On wooden scaffolds or air it becomes a foam wall; on iron scaffolds, reinforced stone.

Construction foam

How to load it

Make CF Powder.
In the Fluid/Solid Canning Machine, Enrich mode: water + CF powder make liquid construction foam.
In Fill mode, move the foam into the CF Sprayer (holds 8,000 mB) or the CF Pack (80,000 mB). They also fill from a tank or a pipe.

How to spray

With the sprayer in hand, right-click. It uses 100 mB per block.

How it hardens

Fresh foam can be walked through and hardens with light: in full light, in about 4 minutes; in the dark, never. Sand hardens it instantly.
On a wooden scaffold or air it becomes a foam wall (painters color it, 16 colors).
On an iron scaffold it becomes reinforced stone, which withstands explosions.

CF Pack

Wear the CF Pack on your chest: while worn, it refills whatever the sprayer uses. That way you spray 10 times as much without reloading.
