Large 600g bag foam solution - works with all foam machines! Can be mixed with 50-200 gallons of water depending on your concentration preference. 50 gallons will produce an high foam stack where 200 gallons a lighter foam with less stack. The foam powder can be irritating to some people. We suggest wearing goggles to keep foam solution out of eyes, and avoid breathing. Some people experience skin irritation - we suggest to decrease the concentration if this is the case. Regardless, keep fresh water nearby to rinse eyes immediately upon contact, and skin after use.
