What is Epoxy?

What happens here

The first step in the described installation process is cleaning the floor. After cleaning and allowing it to dry, a Rust-Oleum primer is applied. Tony identifies this product as Seal-Krete's Epoxy-Shell 550, which is a 'minimal surface prep primer.' Being water-based, it produces no disturbing odors during application and can be applied much like traditional primer or paint. This product boasts incredible adhesion and has been successfully used on various challenging projects. A significant advantage is that it eliminates the need for acid etching, a common but problematic practice, especially if an existing sealer is already on the concrete. The Epoxy-Shell 550 effectively cleans and prepares the surface without harsh chemicals, providing a good etch where needed.

Goal: Properly prime the concrete surface using a specialized water-based epoxy primer to ensure strong adhesion.

What they say

we're going to use in Rustoleum's primer. What is that product we're actually priming with? So the primer that we're going to use on this product is uh in our Sealcrete label. It's called epoxy shell 550. And I for lack of better terminology, I call it a minimal surface prep primer. It's a water-based epoxy. Therefore, it's not going to disturb anyone with odors. uh not going to have an odor when you're applying it. And it really goes on like your traditional primer or paint. Working it out of a pan has incredible adhesion. We've used it from projects that should never have had something go over the top all the way to brand new concrete that was going to get a lot of durability that we thought no way it's going to last. And amazingly, it it's still there to this day. And and that's because Rustoleum at its core is a primer company. We're very good with primers. And that's where this technology came from. Yeah. So, I think this is one of the things I really like about this system. And historically, in the past, I used to come in, I would ac etch the floor. So, there's a lot of um things that could go wrong with acid etching. And you're actually using an acid. I would, you know, spray the acid on, I would flush it up to the, you know, the front of the floor, then flush it down, you know, outside. So, and trying to get like a really, you know, good etch on the floor. trying to get it like 100 grit sandpaper with this primer. You don't have to do any acid etching anymore, right? Correct. No acid etching. Uh could you acid etch? Absolutely. However, on this floor, there's a high likelihood that we have a sealer on here. Meaning that acid etching solution would actually do a good job cleaning the surface, but it actually wouldn't be etching the concrete uh because of the inorganic organic uh capabilities of those two working together. So, we've got our, you
