Foamate Foam Generator
It worked so well right out of the box that I’d recommend it to anyone who wants to get into making aircrete.
I simply poured the shampoo dilution into the tank, connected my air compressor hose and started making a dense shaving-cream-like foam instantly.
Aircrete Formula – 1st Test
I use a digital scale to weigh my gradients. This time around I use 15 pounds of portland cement, about 8 and a half pounds of water, 3/4 of a pound of foam and a pinch of fiber.
I slowly add the portland cement to the water while spinning the slurry with a paint mixing attachment on a drill. I want a smooth, well blended slurry here with no clumps or dry cement on the bottom or sides of the pail.
I’ll add the glass fibre and mix that in.
Then I stop and use an improvised stir stick from a wooden dowel to hand stir the cement mix. This helps free up any clumps.
With the slurry now ready, I connect the air hose to the foam mate and start making foam. Once its flowing thickly I add some to the slurry pail.
Pour Aircrete into Plywood Forms
I have a mark on my stir stick that approximates the amount of aircrete I need to fill one 36″ form. In this case, using a five gallon pail, I need the pail filled to the 8 inch mark as a minimum.
I’ll use my mixer to blend it all evenly. And hand-stir to make sure that everything was blending right to the bottom of the pail.
Then I poured the aircrete into the form — giving it a bit of a jiggle to help settle it into the corners.
Lay in the Wire Grid
Once the aircrete begins to thicken, I gently lay in a galvanized wire reinforcing grid. Pressing it down so it settles right in the center. And smooth the surface with a trowel.
