What happens here

A product called "No Grind Epoxy Primer" by Premiera is demonstrated. It chemically bonds epoxy to concrete without the need for prior grinding of the concrete surface. The demonstration involves lifting a concrete slab using this primer, with additional weights (barbell plates and multiple people) applied to showcase its strong chemical bond, reaching over 1600 lbs of force.

Goal: Understand the strength and application of no-grind epoxy primer.

Tools and materials

  • Barbell with Weights CAP — Applying calibrated weight to the bonded concrete
  • Chains and Hooks Bells of Steel — Connecting the weights and crane scale to the concrete
  • Concrete Slabs — Demonstrating the bonding strength of the primer
  • Crane Scale RESHY — Measuring the applied force/weight
  • Metal Plates — Embedded in the primer to provide attachment points for the chains
  • No Grind Epoxy Primer Premiera — Chemically bonding to the concrete surface

so instead of grinding concrete you can put down our primer put the epoxy right on top saving all the labor of grinding why is it saving all the dust why is it sticky so so this is being held up by just our primer alone right now we're at 699 pounds okay and we're gonna see if we have enough weight here with us to try to break the bond all right load her up we've got a bunch of a bunch of volunteers want to stay away from the ads on each side don't get your toes in there what do we got 800 nine a thousand pounds well who was the fat guy that just stepped on I guess the point of this is to show just how strong of a chemical bomb that's epoxy rules and then let's get someone else someone else 1400 pounds right now here we go all right guys 15. we can't break the bomb this is just primer serious primer did not grind no no Rising no you just applied the primer to the top terrible there over so these guys applied this 16 1600 pounds hey can one of you guys explain what I'm seeing so let's have dogs Yeah so basically what we've done is we've chemically fused the epoxy to the concrete okay right so our product is basically very simple spray down primer and what you're doing is you're chemically reacting in this case an epoxy to a concrete so you're literally chemically uniting the two together okay so reason why that's not it's coming off of the concrete while the epoxy is not coming off the concrete is because it's now part of the concrete chemically so if I understand this correctly you've sprayed these two clams right there you set you just set those down and then you spray it over the top of them did you actually screw them in like these are screwed in here no those aren't screw this there's no bolts no bolts so what we did is right here we did not grind this we sprayed our Fusion primer down and then I'll be putting epoxy over the top well the epoxy was still wet we put these metal plates in there yeah and just let it all cure out okay and so normally if you didn't grind concrete before putting epoxy on there it would just rip right off right if you did something like this but what we've done is we've clinically fused everything together so it's not it's the only way for this to come off of there is for the concrete to break off which is apparently not going to happen we were hoping it would fail at some point yeah thank you gentlemen and this is from Mira Primera ready yep
