The containers come as a 25-gallon kit. It equals five 5-gallon pails of Part B (each contains 4 gallons), and one 5-gallon pail of Part A, to be split between the 5 part B pails (very easy to do) – they can mix one pail at a time, or all five at once if the job size warrants it. To split into different job sites, ensure you mix part A really well according to the TDS sheet. Once mixed, you can split out what you need.
