Fixing or installing a fence post with concrete is time-consuming and labor-intensive. I prefer an expanding foam, which replaces two bags of concrete. It’s called Sika Post Fix — an easy-to-prepare, mix-in-the-bag, and fast setting polyurethane foam. But how do you finish the job once you've installed the post? Sika Canada Inc.
