Great video, but a note on dust control. A shop vac isn’t adequate to pull dust from even a small hand grinder. You need either a pre separator or a pulsing filter cleaner. You also need to pull 25 cfm for every inch of wheel size, that means 175 cfm or greater for a 7” wheel. They make high cfm, small shop vac style vacuums with auto thumpers that pulse the filter. A bagger vacuum like you are using is even better since it separates, pulses, and bags the dust which limits your exposure. Rental places that rent grinders will also rent these vacuums, it’s important to get the right one or it will clog up very quickly and release dangerous levels of dust.

thank you so much for this. I bought the shroud at HD, put it on my rigid 7" grinder, had to use the spacers to keep the cup from melting the shroud, but then the bristles on the shroud would fold into the grinding surface. That tape skirt is the trick plus comparing how much your 7" removes makes me feel better about my grinder. Again. Thank you

I tried this method and was a complete fail absolutely so mechanical bond what so ever. You have to diamond grind or better. If I saw this video I would have never done the citric acid. In fact that should not even be suggested. Still pissed about it.

Curious, I have a new pad to my new garage bc I built a bigger one, but have a old 30 plus year old pad that I want to cover too. So what would you recommend to use on both of them? Was going to use a walk behind diamond grinder. Will that be okay and do a affective job on both pads? As well I have a few low and high points in it that I was going to try and level out, so how can one do that? Bc it seems if to do that we can’t grind the floor for prep in those areas.

Great video…quick question. I see the reason for the cut behind the garage door when the concrete runs flat to the outside. But on my floor, my garage raises up 1 inch after the garage door ( on the inside). Where do I stop the epoxy coating? Should I run it down the inch drop? Will the edge on the rise take the abuse of a car wheel running over it? Any advice would be appreciated. Thanks again for making these.

@trailjockeytj6160 Ай бұрын

You should differentiate the difference between the grind profile and the shot blast profile. You really skim over that. The profile of a shot last will give you a tooth, or a much more jagged edge to bond to meaning more surface area. Meaning more sticky. Well grind depending on. The grid used will not give you anywhere close to the profile of a shot blast. The other thing that is mentioned, but not defined removing the cream opens up the capillaries of the concrete to get penetration and better bond. Good video all in all but I think the shot blast for coatings is the way to go. Although you’d be there for a long time with that little 8 inch machine you were showing you really need a more powerful 220 V or even 443 phase to get that shot last done quickly.

@LeggariProducts Ай бұрын

Thanks for your feedback and for watching!

@trailjockeytj6160 Ай бұрын

Also, that machine you are using, the shot blaster, is an edger as well. You can take the magnet off of one side to get within about a quarter to a half inch of the wall, no grinding necessary and shot glass prep all the way to the edge. I used to sell those years ago hasn’t changed much. But they are very underpowered compared to something. That’s 220 V.

Yes, before applying epoxy, you will want the substrate to be as level as possible.

If you do not have access to a floor scrubber, use whatever you can that will get your substrate the cleanest it can possibly be.
