This is a two component, mix-in-the-bag expanding foam that I’ve been using on my projects. Here is how it works:
Roll the pouch, starting at the compartment containing Component A, working towards the ‘burst seal’ in the direction of the arrows shown on the back label.
Apply pressure to the rolled section to rupture the seal and allow Component A to flow into the compartment containing Component B.
Mix thoroughly by then rolling out the pouch and rubbing the bag along a table edge or any 90 degree surface (no sharp edges).
Mix for 15 seconds only by forcing the material to travel inside the bag, from one end to the other (using a “shoe shining” technique)
Cut the bag open with scissors at the corner
Pour mixed material into the hole. Empty the bag into the hole, pouring some of the material on to the post itself
