Bora-Care lists the following information: Entire void (preventative and remedial): Foam at the rate of 40 ounces of foam with a 2:1 Bora-Care solution in a 20:1 ratio or higher foam. Direct foam down from the top of the void and up from the bottom of the void to cover the surface areas of the wall studs, sills, and concrete wall foundations. I understand the 2:1 BoraCare solution is 2 gallons of BoraCare to 1 gallon of water. I assume the 20:1 ratio for the foam is 20 ounces of Boracare to 1 ounce of foaming agent or about 6.4 ounces of foaming agent per gallon of BoraCare. I am not clear on the rate of 40 ounces of foam. Is this 40 ounces of the mixed solution (2:1 solution mixed with the 6.8 ounces of foaming agent) or is this 40 ounces of the created foam? I suspect the 2 are different but may be wrong.
Using Bora-Care and ProFoam Platinum Foaming Concentrate the mix rate is a 2:1 ratio of BoraCare and 3-8 ounces of foaming agent per gallon of solution is needed which will give you the 20:1 ratio of Bora-Care and Foaming agent. You should only be concerned about getting the foam near the wood and studs. Typically when a company foams walls, they drill holes at the top of the ceiling on either side of the studs and foam down the stud from the ceiling. This way you have gravity working in your favor and you are getting the foam against the wood which is all that matters.
For the injecting portion, "Foam Injection: Locate and inject up to 20 ounces foam (2:1 solution of 2 parts water + 1 part Bora-Care) per board foot into active galleries." This will get you about 40 inside the void you are targeting. You can find this information on page 5 and 6 of the Remedial Label for Bora Care.
