Can you Apply Epoxy on Rough Concrete?

This video explores a common question I get about applying epoxy on rough concrete

I go through the situations when you should not apply epoxy. Also if you decide to apply the epoxy I explain the necessary steps needed to apply the product properly

Your video was posted 2 yrs ago but only now I've came across it (because only now I'm searching for solutions to my recent problem). On a balcony here at my place I had to make a new sand/cement screed which I did for the first time in my live and completely on my own. Which means I had to mix the screed in a big bucket, apply it to the floor, check levels, etc and then repeat about 16 times necessary to cover the small balcony. And to top it all it was a pretty warm day, 25°C plus...Well the result was a very weak screed at places which I repaired by taking off as much as I could the more lose parts and patch it with a new cement mix...Its a mess but its also a balcony we don't really use. So my dilema is, (for the sake of getting the balcony waterproof) would an epoxy floor ( primer + self leveling + epoxy layer) do the job? Taking it that I will do a good job of applying the epoxy of course? I know, soo many questions but in reality I'm a bit stuck here...🙏 Thanks for your help...

Thank you for solving all my doubts. Very clear and informative!

I have concrete countertops with a raw edge. I would like to create a clean edge. I don't want to grind or cut it as it's thin in some places. I thought I could build a frame/mold situation and fill in the rough edge with epoxy. The concrete is solid, not soft. Would this work?

I would strengthen and tighten that crumbling, loose, powdery concrete by trenching it with an acrylic, polymer admixture before trying to put anything over powdery loose concrete.

What exactly is the difference between diamond grinding new pour self leveling compund layer vs simply broom finishing the new poured self leveling comound. That pits the groves for the epoxy to adhere no? I don't want or have ro diamond grind and seems a good alternative ?

What do you think about a concrete garage floor where there’s a lot of aggregate showing? It’s in good shape other then that. Very minimal patching for cracks with an epoxy patch kit, but do I need to patch all these areas where it’s down to the aggregate. Just curious if the epoxy coating covers this? What’s ur best advice for me thanks

I pray you see this comment and respond. I live in the Caribbean where we use cement bricks and plaster to build homes. Galvanize roofs and all that. We mainly have tile available here and everybody tiles everything for the most part like kitchen, bathroom countertops and floors...walls etc. My question is, can epoxy be used directly on concrete surfaces like a kitchen counter or concrete pattern wall. Where cement plaster was used to make the wall look like stone, so a very bumpy plaster and not a smooth wall plaster. In the shower as well. I wanted to know if we could just paint the shower walls with epoxy? And not just a simple one coat clear epoxy but the granite, marble look epoxy on the walls. Can it just be painted on the wall and how would I go about that? What would the prep need to be? Sand the walls till smooth, prime sith epoxy primer and then pour from the top, the different epoxy colors to get my marble look, then brush them in maybe (with what kind of brush? A sponge brush? If that is what I do.) Then blow torch the whole thing for bubbles n such??? Not even sure epoxy is available for us to buy here but I still would like to try it and would love to know how to apply it directly to concrete walls. Pray you see this. Thank you

[vLife]

I'd like to epoxy over new, well compressed soil cement. possible?

[MysteryScienceGaming]

have you ever seen those finished concrete rollers people use decorative purposes? Stone, tree bark etc... could you just make a concrete roller that already had a profile of CSP 3-5 therefore negating any need to grind or shot-blast on new concrete?

[cyclonudista]

I have a (vertical) rough uneven surface with stones, how can apply it there?

[patrickg]

Should you apply a primer to a bare concrete surface before applying epoxy but after already prepared by diamond grinding?

[desigerz]

I applied a leveling cement on my rough concrete emediately after grind it to apply epoxy on it, is it OK please!

Can I pour surf board epoxy resin on a concrete counter top? It doesn’t seem soft and powdery. Also will not be holding anything heavy on top of it. It would be a front desk that was built for an office.

Keen to join your course sir. Will i be taught how to apply Epoxy Flakes for toilet flooring and toilet walls?

[ivatrifonova]

What about the other way around? Do you think concrete will stick to epoxy covered surface?
