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

What happens here

Apply the Polyflex 93 sealant to the saw cuts by pushing the gun's tip along the joint and extruding the product. Ensure you overfill the saw cuts, creating a slight bead above the concrete surface. This overfilling is crucial because the excess product will be scraped off later to create a perfectly level and seamless finish. When moving between joints or stopping, keep the gun's tip pointed downwards to prevent the two-part product from flowing back into the mixing tube and prematurely activating or curing inside the gun.

Goal: Fill saw cuts with Polyflex 93, ensuring proper overfilling and gun handling.

Once it mixes through this tube, it sets up in 45 minutes to an hour. Once your tube runs out, you just cover it with the tip. And I'll get another tube. When I get close to the outside, I'm going to slow down cuz I don't want a lot pouring outside the door. I just started thinking I stuffed a piece of backer rod. So, I'm just going to give you a simple tip like if when you're moving around, you know, with the product, you know, don't invert your gun upside down because this stuff can start pouring back down inside the tube. tubes and cause it to activate inside the tube. So, keep tip down when you're moving wherever you're going. So, just like this. My tip is down. You don't want to walk with the tip up. So, next crack we're going to move over here.
