Everybody might hear so we're going to be using crack welds pro concrete crack repair kit today to fix some cracks in this concrete floor. I'm going to take you around and show you a crack we're going to be fixing. Take a look at this. Those are the cracks we're going to be repairing and we're going to show you the steps to use to take this kit. They have a DIY kit also the difference between the DIY kit and the pro kit is the pro kit has the dual as this dual cartridge cocking gun whereas the DIY kit is the single cartridge. All right guys here's where you get in the kit you get two dual cartridges you get two bags of silica sand you get your gloves and all your nozzles a couple of little cups and what you don't get in this particular kit is you don't get a dual cartridge cocking gun that comes in one of their other kits so this kit's just for the refill once you already have that cocking gun then you can just buy this. All right guys so what I'm doing here is I'm preparing the cartridges it comes with a little twist off stopper that you just got to snap off and then it's got this little back flow resistor you put right back on and that just keeps the material from from back flowing back into the cartridges and then you just screw on the nozzle put it in the dual cartridge gun and you're ready to go I'm going to put my gloves on got my little cup I'm gonna purge a little bit of the material out before I start putting it in the crack I want to make sure it's thoroughly mixed together before you put it in the crack so I purge a little bit out then I bring it over to where I'm gonna start as you can see we got the area nice and clean everything's out of our way and then I just start wetting out the crack and Darren's got some silica sand in the cup he's gonna pour some silica sand in the crack that I just wet it out and then he's gonna take a putty knife just a little putty knife right there and make a paste out of the sand and force it down into the crack so he just keeps working the crack behind me with the sand and the paste and I just keep wetting it out with two people this moves along pretty fast pretty easy that's why they call it a DIY repair kit so if you need to wet out a little bit more of the sand you can just go back over it a little bit make sure you make a good paste out of it and you want to leave it a little bit high as you as you putty knife it down into the crack you don't want to get it lower you're gonna have to repair it again so just leave it a little high you're gonna end up grinding it all off anyway if you would do in this all by yourself which you could pretty easily you do probably between five and 10 feet you'd wet it out put the sand to it use your putty knife make a paste fill it in do another five to 10 feet and just keep going that way with two people you can move along really fast that dual cartridge kit to that will do a lot of linear footage of crack we had a bunch of little ones on this floor we're eventually gonna make doing epoxy floor over this concrete that's one of the reasons why we're repairing all these you can see I just keep wetting it out just a nice fine line of repair material in the crack Darren's just putting enough silica sand to fill the crack make a nice paste and fill the crack I'm wetting out the sand again if I need to and then I just keep going key is here just to work steady you know you don't want to start and put the cocking gun down take a phone call the stuff will dry pretty fast but if as long as you stay steady you're gonna be just fine you can see there's quite a few cracks in this floor couple little chips and pitted areas here and there that we we repaired also but that's it Darren's really doing a good job filling the crack in keeping the material a little bit high rate on seal makes a really good product I mean we've used crack weld a lot and that's what it looks like after it's hardened up so here I am I got my little my little five inch grinder hooked to a vacuum and it grinds off pretty easy you can really move right along with this thing and once you grind that off it's it's fully repaired it's welded back together it's nice and smooth and then you're ready to do whatever you need to over it you know like like I said in our case we're gonna put a nice metallic epoxy floor over this so we had to make sure this floor was perfect before we did that grind the next stuff off I mean it literally takes seconds to grind it off it buzzes right off pretty good with a good grinder you could use a four inch to walk grinder or a Bosch grinder or anything you get with a diamond cup wheel I definitely recommend hooking a backing to it though you can see I'm just moving right along not really working very hard just lightly grinding it that stuff comes right off that's a fully repaired crack you could leave it like that if you wanted to let's say it was a garage floor you could leave it just like that just put some clear sealer over it you could you could use a concrete paint over it or in a foxy then we get them all over the place that's what the crack looks like fully repaired it's just about invisible I mean the crack itself is gone this stuff's the best stuff I'll use guys
