First, you need to calculate the volume of the space you want to fill. Then you have to calculate the quantity of foam needed to fill it. The instructions will tell you expansion rate. I think the 2lb density expands like 25 times its original volume.
Use two measuring containers, one for Part A, one for part B. Mark them with a Sharpie so you don't reverse them on the second batch. Pour the contents of both measuring containers into a larger container with room for at least 100% expansion. Mix it fast with a power mixer on a drill. You have about 30 seconds in this warm weather before it starts to expand. Mix it right where you intend to use it. You won't have time to climb in the boat to pour it out if you mix it on your work bench.
Pour it out as evenly as you can. If you're pouring it on a slope like the bottom of a hull, start on the uphill side and let it run down. Don't mix too much at a time or it will get away from you. Mix no more than you can pour out in 30 seconds. You can always add more.
Once you've done a few batches, you'll get a sense of how much time you have to work with it.
