Foam Poured Around Anchor Base.

Foam Poured Around Anchor Base

Step 6: With the anchor secured, it’s time to replace the foam. We recommend using fence post foam—it comes in a two-part bag that you mix by hand. Once mixed, pour the expanding foam into the opening around the anchor. It will fill the gap and harden in place. Allow about an hour for the foam to fully expand and cure before moving on.
