Fire Table – Concrete Sealing
As I said in my last post, today's post is about sealing the concrete insert of our new fire table. And as I also mentioned last week, I made a mistake while sealing the concrete. But we’ll get to that. First, let’s talk about different concrete stains. There are basically four types of concrete sealers, as I found out while researching the best one for my project. The four types are penetrating, acrylic, polyurethane and epoxy. Each one of these performs the sealing in a different way. Acrylic, polyurethane and epoxy stains all build a protective film on the top of the concrete to provide protection, albeit using different chemical compounds. Penetrating sealers, typically some sort of silicon compound, provide protection by reacting chemically within the concrete. These don’t leave behind a protective film like the other stains. A key benefit of the penetrating sealers is their ability to let…
