Best prep video I've seen yet.

Hi, after mopping the floor will be wet, how much time should be given for full drying of the floor before applying the epoxy coating

[@rcrg81]

where are you getting your power from?do you carry a generator or do you hook up to the homes power? does it have to be a 50 amp breaker? sorry for all the questions. thanks

[@arcarc7229]

What grit were you using?

[@akbarnitti]

Hello how are you? I’m starting an epoxy business was soon and I must say you do nice work. I have a question what type concrete repair that you use to fill cracks. I know time is money 15 mins you can’t beat that. Appreciate your feedback. Mr. Akbar

[@aaronfleming7746]

Hey, curious how much do you charge for an area that size, the prep plus the epoxy finish? Whole thing. Just to give me an idea

[@powerhouse6175]

They have a Y adapter for your vacuum like 10 bucks so you can use two vacs at once

[@charltonheston969]

The diamond cup wheels I've seen don't have a grit # or say how aggressive they are

[@elricm13]

With the water mopping the last step, how long do you wait for it to dry?

[@purepoxy-hawaii8786]

until it dries up. you do a damp mopping, not soaking wet. usually an hour or so, depending how hot it is that day.

[@MotorcycleEnhancements]

I heard that water may react with the epoxy coating. I've seen others use a power washer to remove impurities, then let it dry and then apply epoxy.

Would the gouge mark visible after applying epoxy paint?

[@KB82424]

Yes they are😂

[@Tiecongli]

Indeed, I have lot of gouge marks because I want to cut time and didn’t spend time to grind even them down then outcome was quite awful

[@jodyjennings8472]

I used a wire brush sander to smooth crack fill areas and it burned and left black marks in the cement how do I do I get that off? So that I can be sure epoxy will stick?

[@OmegaAlphaDu]

Grind it off

[@Villah496]

I believe you need a diamond grinder to get that off

[@jodyjennings8472]

It turned out nice.

[@lionintu]

So you filled the crack with sand, but is there a specific type? Then you pour ed a crack filler, I assume an epoxy, was it a specific type?

[@purepoxy-hawaii8786]

Sorry for the late response... It's just clean sand you can get at HomeDepot. The crackfiller is something we sell: purepoxy-hawaii.com/store-epoxy/ PP-CF Polyurea CRACK FILLER (2 gallon kit) $250.00 PP-CF is a two parts, high penetration, fast setting, hybrid polyurea for repairing and re-building damaged concrete. The product is a 1:1 ratio, easy to mix system that is 98 % solids and VOC compliant. The PP-CF can be used to set anchor bolts, repair damaged control joints, fill spalling, and rebuild vertical curbing and steps. Sand or gravel can be added to extend the volume of the material and acts as filler for repairing large spalls, holes and cracks.

I was asked from a friend about going into business doing this. I see that it is a good idea around my area and im interested. Do you have any advice for me or is it a risky business. Friend has experience but im financing the ordeal. Just wanted to know the business aspect of it from what i see here. Seems like a big project. Good video though...

[@diegocarrillo9573]

How is it going so far?

[@michaelbacile8439]

Just buy some used or cheaper equipment to start off with. That’s your biggest expense. It’s a pretty easy industry to get into, learning the processes is the only part you should be focusing on

[@henryrgdelos6398]

Hi, I will use PE-100 for Base on a 110ft2 floor. Do i need to 110oz of B and 220 oz of A on my mixing ?

[@purepoxy-hawaii8786]

If it's only 110 sqft, then you need one kit. one full kit will cover 150 sqft. 2 gallons of A and 1 gallon of B.

[@purepoxy-hawaii8786]

I made a mistake. one kit will cover 450 sqft. So, you need 64 oz of A and 32 oz of B

[@KB82424]

Just a smooth finish would of done the job as long as the shiny ports are grinded it would be just fine

[@tazaxx21]

Everything I've seen says that high-solids epoxy requires a rough surface to adhere to.

[@user-ct2tt9zy8h]

Video needs to be taken off line. Grinding concrete without a respirator is dangerous to any operators health.

[@victorbremer8097]

You mean removed from Online? Because number one “off line” isn’t a thing. Number two, saying taken offline does not make sense either.
