Painting over epoxy flooring?

[mechanicaldamage]

Good morning. I have done a bit of internet searching and haven’t had any luck and was hoping maybe someone here could help me out

Currently converting my shop/loft house into a proper house and would like to re paint my epoxied slab.

It was a home kit I did (rustolium) about 8 years ago, It has held up very well no peeling or chipping and has seen very little traffic or oil/ grease.

It’s the grey colour with colour flakes and the ‘texture sand’ added to it so it’s pretty much impossible to get it feeling grit free.

It’s a heated slab and the concrete work is excellent so instead of putting down flooring I was just planning on rolling a coat of paint over it here now and using a few area rugs in the high traffic areas

Does anyone have a paint suggestion for doing this would ‘floor and porch’ type paint work? Or should I be looking at anything else?

I just thought of the idea of re epoxyinf with a different colour but after a little reading it sounds like it could be a bit of a gamble and a lot of work?

Thanks
Jeff

The experts will chime in but if it were me and I had my mind made up to paint it I’d rent a burnisher with an 80 grit sanding pad to scuff the floor then apply the paint of choice. You have to properly profile the surface or not even the best application will adhere.

Thank you for your reply thinking a little more on it it probably wouldn’t take too long to ‘scuff it’ with 100 grit on orbital sander and if it was hooked up to shop vac with a drywall dust bag it might not make too aweful a mess.

I have about 850sq feet to do if I go that route

I know the original coating has bonded well as I pried up some glued down interior walls and the 2x4’s came apart still glued to the coated floor

This is avaliable locally as a tintable base paint

Hello. What your plan entails is applying an acrylic latex paint over an actual epoxy coating. In other words, you would be applying an inferior product on top of one that has held up well for you so far. There is a big difference between latex paint that has been fortified with a small amount of epoxy resin versus an actual epoxy coating. The article below explains the differences.

As Mikec35 said, a floor maintainer with an 80-100 grit sanding screen would make quick work of prepping the floor. However, I would highly recommend staying with an actual epoxy product or similar type of coating vs applying paint.

Also, Rust-Oleum has had a product out for a while now called Rust-Oleum Garage and Concrete Floor Primer. You can apply it directly to an older Rust-Oleum coating as long as you clean the surface first. Once cured, you can then apply a Rust-Oleum coating (epoxy, RockSolid polycuramine, etc) of your choice directly to it without prep. I included a YouTube link below. I would not recommend this product for a commercial coating, but if you stay within the Rust-Oleum line of products you should be fine.

Thank you very much for that. I don’t think either is avaliable locally but the project could wait a few days while I order it in. I will read into the info you provided shortly

The only comment I will ad as this will now be the ground floor of a house and other than foot and pet traffic it won’t see anything else

Just curious how much dust gets flying around with a floor maintainer anyways?

 

[mikec35]

Not much dust, you are just scuffing a hardened surface. If you were grinding concrete you'd see a ton of dust. Your existing epoxy floor is adhered well, I wouldn't think you'd see hardly any dust at all.

Please let me know if you use this, and how it works. I need to recoat my garage as well. Like you, my original coating is well adhered but it's in need of a refresh. This product seems like it would work well, and is available to me locally (at a Home Depot).
Thanks!
