Every Project Is Unique

Hopefully none but it happens. There are rules of thumb based on experience and “regular” circumstances like 50 feet per gallon, but that figure can swing widely. Experienced installers are way more productive than newbies. Let’s say you pour a quart of Mountain Grout Flexible into a five gallon bucket. Mix in one ounce of Mountain Grout Accelerator (stir it well), then pour in one ounce of water, mix it well and wait a few minutes. Observe the resin start to move a bit, then turn cream color, the begin “growing”. We call this a free rise expansion. A quart will yield a volume of approximately 25 quarts or close to a cubic foot of foam. When used to fill voids a “free rise” yield can be fairly accurate but keep in mind, when the expanding foam is confined, it cannot fully expand so the yield goes down.
