Large area to scuff and wipe

What's the best way (tools/process) for prepping 1100 Sq.ft.for a recoat?

Buffer with a sanding screen.
Wipe clean using a micro-fiber pad, moist with denatured alcohol.

Typically, I would suggest sanding screens as well, but with this being quartz broadcast, screens tend to tear. Paper would work better (100-120 grit) IMHO

A vibrating sander would work better in this instance than a rotating one. After sanding, vacuum and wipe with denatured alcohol or xylene

Quartz broadcast? That is a different story.
Depending on the level of roughness and maybe it's very rough???

A Malgrit brush will work or it may need be to ground down then add your epoxy, then urethane.

Xylene wreaks and will make you light headed if too much is used. That is why the denatured alcohol. If you do this work regularly, you try to help preserve your nervous system.

Screens, if this is a rough floor, will be toast in about 15 seconds, especially if you made a quartz broadcast using urethane. Is that why it's so rough? You used urethane vs. epoxy?

It doesn't feel rough, you can feel texture, but not sharp.
I can run my fingers across it no problem.
It won't snag a microfiber rag.

You can try the screens. However, you will need at least 80 grit if this is urethane.
100-120 won't do much. Any high points will eat the screens up so get a few as back-ups.

The last time I did this we had to use grit pads to break the surface. Real aliphatic urethane is tough stuff.

A Malgrit brush will work

That looks alot better than a sanding pole or palm sander.
Black or green or
Looks like they should be used w/ water?

Yes, quartz broadcast into epoxy, aliphatic urethane top coat.

I recently used the orange on a project. We used it over a rough broadcast that needed another coat of PAP.

Its a real blessing to have your own crew out there using the products you sell. Separates us from the guys who BS there way through it. Unfortunately, when this happens people get hurt and money is wasted.

Looks like the orange is the roughest, grit wise.
A little off topic, but could the orange brush be used to prep. (instead of a diamabrush)
Assuming no heavy coating, only previously sealed or dirty concrete?

IMHO for an epoxy job, no.

It's specialty is getting into the nooks and crannies. We were the first to use the product in this manner. It's designed for heavy cleaning, not prepping.

We needed a solution and it worked.

I don't think it's tough enough to prep concrete, just scratching coatings.

Thanks for the replies, Know what I gotta do now.

I need to do the same for a re-coat. Anyone have suggestions for source of the orange bristled wheel, rent or buy? HD does not rent them at my store. Thanks

 

[LegacyIndustrial]

We sell them. You can't rent them . http://www.legacyindustrial.net/products/diamabrush-tooling/malish-rotary-grit-brush.html

Thanks Scotty. I'll check with HD to see the brand, size, and rotation of their rental machines and then order from you.

I'll save you the trip.
The Clarke RSDC is 16" and CCW.

Thanks Scotty. One question that may be of interest to the forum: the instructions on your site say to use wet. I'm guessing this is for the tool's original scrubbing purpose and may not be required for abrading paint? I would prefer not to introduce water into the process, if possible. I hope to use the brush, vacuum, and finish by wiping down with denatured alcohol - does that sound like the right plan?
