Poured exterior patio 6” slab between existing block and poured wall. I planned to build a wood deck to same grade off this patio. Top of wall and blocks looks like shit. What can i do, resurfacer on top? Put a 2” slab on top? Set some kind of tile all over it?

Bump

tile or thinset to smooth out the imperfections. but desu the concrete looks tacky for a patio anyway you should cover it or stain it or something.

Yeah, I’m thinking tile, any recommendations there? Thank you

>>2918773
Terracotta or porcelain

My grandmother house is partially concrete, so they just put a floating floor over it. You can also stain it or resurface it like the texture stuff in those fancy garages people don't actually work out of.

Gneiss tiles are the best option for outdoors, and it's cheaper then limestone.

Gneiss seems not available in my region thank you tho

I’ve never known any resurfacer to last very long.
Not much sticks to concrete very well.
Tile won’t work outdoors because the thermal expansion coefficients will cause it to crack and come loose eventually.

I’d try and grind it down flat ((like they do with industrial floors and countertops sometimes) and just apply driveway sealant and maybe add some pigment to it to even out the color (like a toner, so it’s still transparent).

While it’s not that durable, it’s easily maintainable.

This is bullshit. Lay outdoor tile regularly in rust belt. Modified thinset, epoxy grout. You will need to use small tiles because the concrete won’t be flat enough. Regularly use resurfacer to smooth over or patch small areas in exterior and have no problems (provided it is not vehicle traffic). Again the poster above is completely incorrect and one of the reasons /DIY/ is inferior to plebbit.

This has to be bait

>>2919189
Lol, wut?
Are the redittors in the room with you now?

>>2919124
you probably did a nigger job and just dumped the resurfacer on top of the old concrete instead of etching and cleaning it first.

>>2919124
>Tile won’t work outdoors
Obviously bullshit. There is exterior tile everywhere in my city. The old tile in tunnels and in the underpasses is a great example. It still looks fantastic and it's been thete for ages.

Ain't they make'a 'crete glue, too?

>>2919124
they don't last because people salt the shit out of ground tiles in residential

>>2919509
How does one etch and clean to prepare for resurfacer?

>>2919613
Nta, but etch usually means use an acid. So you probably power wash it, maybe even use some dish soap and scrub if it's really dirty, possibly use compressed air to blast any loose particles out, use some kind of acid to add some "tooth" (etch it) and then rinse. I know there is concrete glue you can apply to the surface to increase adhesion and there are additives that can also increase adhesion. Sika sells some bonding agent, you replace some of the water with it. I'm no expert, tho.

You can and should go even farther, you can scarify the surface of the concrete with this huge diamond wheel to roughen it.
We even do that before epoxy paint.
If you’re going to try and attach something to concrete (like thinset, grout, or lime plaster) you usually rake the surface of the underlying concrete before it’s cured so it’s extremely rough.
This is even rougher than a broomed finish which is generally so people don’t slip (something else to be careful of if you’re installing glassy porcelain tile for example)
If it’s a small area, and you’ve got lots of time, you can use an angle grinder and cut hundreds if divots into it to give it some tooth.

Perimeter is unfinished, interior section is broom but rough. So basically etch and then i can use thinset to balance out imperfections over the block section and tile it out?

Thinset, membrane, terracotta tile, sealer
