How it works

It follows your framing sequence.

Nothing about layout changes. The lumber shows up stamped, the plate line gets rolled before the walls stand, and the interior gets sprayed before windows and mechanicals go in.

Before the package ships

Lumber arrives stamped

MFB-34 EPA Safer Choice Fire Retardant treated Douglas Fir leaves the mill code-evaluated and stamped per member. Your crew cuts, nails and hangs it the same way. Bright uncoated steel nails are fine.

On the deck, at layout

Roll the plate line

Snap your lines as usual. Roll Snap-Plate Mold Defender™ three inches wide of the line and coat the bottom of each plate before the walls are stood. The walls go vertical on the same schedule.

ASTM G21

As the walls go vertical

Spray the interior lumber

Before windows and mechanicals go in, the framer you already hired sprays the exposed interior lumber with MFB-31 from a backpack or cart rig. We train the crew and set the equipment.

At close-out

Hand over the paper

The evaluation report, the test standards behind each layer, and the application record for the address. Something to hand to the building official and to your risk manager.

Four steps, no change to layout

Snap your lines as usual

Nothing about layout changes. The framer works off the same lines.

Roll three inches wide of the line

The extra width is what interrupts horizontal moisture movement into the plate.

Coat the bottom of each plate

Done on the deck, before the walls are stood.

Stand the walls and keep framing

Single application, roller or sprayer. The walls go vertical on the same schedule.
