How to Properly Fill Cracks & Saw Cuts Before Epoxy | Rust-Oleum Concrete Saver Pro + Poly Flex 83

What happens here

After the Polyflex 93 sealant has cured for approximately 45 minutes to an hour, it will be firm enough to scrape. Use a floor scraper with a fresh blade to shave off the excess sealant from the surface of the saw cuts. Position the scraper blade at a shallow angle and push firmly to remove the cured material, creating a smooth, flat surface that is level with the surrounding concrete. This process ensures a seamless finish when the epoxy is applied. You may need to replace blades frequently as they dull; for a single-bay garage, typically 2-3 blades are used, but this job required 5.

Goal: Remove excess saw cut filler to create a seamless floor surface.

All right. Now, I'm getting ready to uh do our filler for our saw joints and our footing joints. So, I'm going to be using, you know, two different products. I'm using a Rustoleum product, uh Concrete Saver Pro. This is a non-sag sealant. So, I can if there's any like cracks in the corners or cracks on your footings or stem walls, this is a non-sag product that you can fill those cracks with right here. And so, this is a one part product. Just going to put it into a standard caulking tube. We've got a two-part product. So, this is Polylex 93 and this is a um high strength poly ura elastimemer that's going to go in our saw cuts. So, it's a two-part product, 100% solids. It's a self-leveling product and a fast cure product. So, we're going to fill you'll overfill your saw cuts and then you go back, it dries about 45 minutes to an hour. You go back, scrape it flat. That way, you'll end up having a seamless floor. I like my floors, you know, being seamless. I don't like to see saw cuts. Um I don't like to see products, you know, that shrink and like kind of like leave an indentation, you know, where the saw cut is. We like to have a seamless floor. So that's this product. Uh eventually when you set it up and begin gunning it, uh the first uh tube of the stuff you're just going to eject it and get rid of it, but then as after that, you're going to begin filling your cracks with it. the one part product. Uh you you can just go put it in the cracks. We're just trying to get the fine crack along the footing where the uh seam board is. I'm just going to fill that crack. When we go back and prime the primer is going to cover over the top of that board and then our coating, you know, our layers of our coating will end up filling that in. So, this is a toolable product that I'm actually going to be applying and tooling. This is a non-toolable self-leveling product that you just uh scrape off. And you'll see what that looks like, you know, as we go. So, I'm going to begin the process doing our saw cuts and um joints. Once again, this is Polylex 93. Kind of just sets in the gun just like a typical cocking gun. Snaps in place. So, I just pulled off the cap. There's a little cap right here. Just going to discard that. Typically, keep, you know, just like a 5gallon bucket. You know, keep some rags available. Keep some latex gloves available. This stuff, you know, is kind of nasty. You don't want to get it, you know, on yourself. So, guns all ready to go. Start gunning it.…
