/diy/ - Do It Yourself

D I WHY THE FUCK DID YOU DO THAT?

I always wanted to see exactly what happens when some dipshit fucks this up. Take pics and video.

>>2746000
>>2745999
so you dont know?

It might work or it might be shitty and break
You dont have blankets or a heater you can put on it?

>>2746015
how do you put blankets on fucking self-leveling mix, dumbass, its a liquid

go buy a torpedo heater
either propane or kero/diesel whatever you prefer

>>2745996
as long as it doesnt freeze it should be ok just leave it alone nothing you can do for it now anyway

>>2746015
Does it stay liquid?

>>2746022
>how do you put blankets on fucking self-leveling mix, dumbass, its a liquid

>"scratched the surface with my fingernail and it comes off like sand."

How does one "scratch" a liquid?

>>2746032
?
he's talking the day after

>>2746015
I put a propane heater on and the temperature is probably around 10c now, but it was probably around maybe 2-5c the whole 24 hours yesterday, isnt that the most important period of time?

>>2746029
>as long as it doesnt freeze it should be ok
what about the first 24 hours when it was cold?
I shouldnt be able to scratch some of it off, right?
it might be okay after 2 days but I wont know until then
how much strength will be reduced long term since it was below 10c during the first 24 hours?

The longer concrete dries the better…youre fucked

>>2746046
well its still going to dry at 5c

>>2746044
>how much strength will be reduced long term since it was below 10c during the first 24 hours?
ok well whats the chemical formula of the mix what was the slab temp, air temp, rh, every 30 seconds?
its either going to take a little longer or its completely fucked. stop scratching it leave it 48h at temp and then see where you are.
if its a garage maybe you need to repour if its a closet maybe flatness is important but strength isnt.

>>2745996
Nope, you're fucked..

>>2746103
source?
you're just saying that and you have no idea

>>2745996
I don't know about concrete specifically
But every time I've tried to cure something at a lower temp than is recommended (epoxy, polymeric sand, glue) it stays gummy forever
Best of luck

>>2745996
You fucked big time mate.
Get that out as long as its wet.

>>2746015
Blankets do not work that way.

Wait so:
1.you poured a self leveling compound on an existing cement slab.
2. The temperature was too low for it to set, and this was like...24 hours ago
3. You realised this and increased the temperature so it would set

Quick google:
>https://www.screedpro.com/post/tb001-applying-self-levelling-compounds-in-cold-weather
>These types of products should not be installed after 2pm on a construction site

where there is no internal heating and when ambient temperatures will drop below 8°C

over night. If the ambient temperature is 8°C the concrete substrate temperature would

be 5-6°C and at these low temperatures cement-based materials are put to sleep and

thus severely affecting the curing process. In most cases the strengths will be greatly

reduced but, in some instances, where the applied product has been put to sleep it may

need to be completely removed and re-done.

So it seems you're way lower than even the minimum temperature and it may not cure properly.
You could wait and see, risk having to remove it. Or you could try removing it while wet, which would probably be a huge fuck around as well.

>>2746036
Retard

>>2746044
A self leveling mix is going to be loaded with plasticizer. Plasticizer retards the cure. On top of that it’s cold. If it does cure it’s going to take some time.

>>2746163
I’m assuming they mean a heating blanket specifically for that purpose. Concrete does create heat on its own through the curing process.

>>2746163
Yes they do

>>2746164
lets say it didn't cure properly and isn't as structurally sound as it should be, can I still tile over it?
I can walk on it just fine. It's just that when I scratch it, some particles come off. Maybe that's because it's only been 30 or so hours?

>>2746181
>Plasticizer retards the cure.
so does that help or hinder me?

>>2746199
Did you eat it too, it seems like you might also be retarded.

>>2746279
no need to be mean anon

>>2746199
Generally, concrete gets harder over time.
Even after 20 years, its hardness still increasing.
My suggestion would be to give it a little longer to cure, and topcoat it with a sealer.

>>2746199
> >Plasticizer retards the cure.
>so does that help or hinder me?
What I’m saying is that the concrete you’re using cure’s slowly as it is. Coupled with the cold, it’s going to cure pretty slow. At this point though, if it isn’t set I can’t imagine it ever will. At this point though I doubt it will hurt to give a few days. I’ve had pours I was sure wouldn’t cure and they did. Also you say the top comes off with a fingernail. It’s possible you fucked up the water to the point it bubbled on top but too much that it won’t cure. Mixes with plasticizer are much harder to dial in the water. I make concrete planters with it and I measure everything by weight.
However if you used way too much water you may be screwed and colder environment would make it worse. Proper curing requires many variables you may have done too many improperly.
>>2746477
Concrete isn’t going to set over a long period of time. It has specific windows and if it doesn’t meet them in the first couple days, it never will. The reaction time varies somewhat but not that much. After 28 days it should be at or near 90% anyway so any extra hardening is negligible for most applications.

>>2746491
So my question is…..you GAY

>>2745996
it will dry, but it may not properly cure. it will have poor adhesion and will be brittle. sorry mate, its gonna be bad, and will probably need to be redone.

>>2746491
Well at this point I can still scratch some sand off the surface but it's hard and I can walk and jump on it.
Should I just say fuck it and tile over it? What would happen over time if it didnt cure properly?

I need to raise it up another 1/2 inch, could I just put another layer of self leveling over top?

>>2746681
>and will be brittle
What's the worst that could happen if I tile over it?
Could I put another 1/2 inch layer of self leveling and then tile over it?

1/2
>>2746890
>Well at this point I can still scratch some sand off the surface
If you mean the very top as in maybe an 1/8 of an inch you may be fine. I wish I could tell you better but I only have experience with making planters. Definitely doesn’t translate to floors completely. I can tell you I’ve had the experience you described and concrete set just fine and was as strong as normal. I think it’s caused by water being a little off and/or air entrainment (which I forgot to mention). It technically makes the mix weaker but it may be strong enough for you.
>but it's hard and I can walk and jump on it.
Definitely a good sign, but again I don’t have experience with floors.

>Should I just say fuck it and tile over it? What would happen over time if it didnt cure properly?
It’s curing “properly” now. The question is is it proper enough for the strength you want. You may have gotten all the variables close enough that it will be strong enough. I can’t really say unfortunately. I would try to add weight to it, maybe roll some heavy shit on it and see how it holds up. I’m no chemist but I can’t imagine it will degrade over time. I’ve never seen it happen even when I screwed up the mix. Like I said the question is the final strength.

2/2
>>2746890
>>2746918
>I need to raise it up another 1/2 inch, could I just put another layer of self leveling over top?
You can and especially if the surface of your first pour is rough (scratching sand off) it will bond pretty well. Definitely lay down some acrylic bonding agent first. Don’t let it look or get overly wet because then you’re going to screw your water ratio. You just need a thin film. Again remember you don’t know what the strength of the initial stab is.

Standing back as someone who has nothing to lose either way, if I had to guess I would say as long as it seems to hold up with heavy shit on it and you can scratch the top of but get IMMEDIATELY down to a level where it’s firm and actually concrete, you’re probably ok. Please remember though that like I said I only know from making planters and the biggest one I’ve made is 100 pounds so I’m really no expert.
>>2746500
Your mom certainly doesn't think so.

>>2746920
*Dont let it pool or get overly wet

>>2746027
Not very expensive to rent (canadian dollars)

>>2746920
> acrylic bonding sealer
this. I used this blue stuff and it’s amazing—I’m using the unused remainder as a waterproof glue since it’s got acrylonitrile butadiene in it. this stuff will also ‘lock in’ any sand-like shit on the surface.
When I poured mine, there was this dusty/gritty layer on top and it was done correctly—they say you need to use the bonder between lifts.

also consider laying down a steel mesh of some kind if you’ve got a full 1/2” to work with.

if you can dig out a piece of the old floor, you can mix a tiny bit of the new and let it cure, then compare the two (try breaking it in your hands and whatnot) to get a feel for how the first layer cured.

Tried to save time and money using a short cut
Ends up a shit show. Thank God I retired from this business. People these days are so fucking stupid

>>2746956
Im sure many people are glad you retired. Stay mad.

>>2746477
This, to be sure, wait 20 years before you tile over it

>>2746958
Never knew a happy concrete guy

>>2746920
>Definitely lay down some acrylic bonding agent first
isnt that just for surfaces you are going to paint?
Can you link to to whatever this shit is, preferably home depot

I was going to use mapai waterstop/crack isolation membrane, would this be good enough?

>>2747172
> isnt that just for surfaces you are going to paint?
…. Uh, no? Why would I tell you to use that if it was? I don’t mind helping but are you using google for this at all?
>link
Just google concrete acrylic bonding agent.

>>2747281
>Just google concrete acrylic bonding agent.
ok

Should I use mapai waterstop over the acrylic bonding agent?

Holy fuck I could have finished 6 jobs by now

>>2746015
>blankets
lmao

>>2746015

kek. pour some hot cocoa on it too

>>2747849
>>2747864
Concrete blankets are a thing but you can also just use normal blankets, insulated tarps, foil, straw etc

>>2747849
Yes?

Are /diy/ people actually this retarded?

>>2747876
>see rhetorical

Thus quoth the Raven……never more

OP here

The floor actually hardened pretty good, it doesnt scratch off easy anymore.
I think I'm good.

Thanks frens.

>>2745996

Temperature is very important for cement, mortar, grout etc.

I would get some kind of heat on it and see if that will dry it out. If it was well mixed I don't see why it could not still work out.

But if you get some hot heat on it for a day or 2 and it's still acting weird you may need to pull it all up. You can't put a floor over a surface that is acting funny.

>>2748348
It doesn’t dry, it “cures” by chemical reaction.
Well, it does dry, too, but that’s not what hardens it. In fact, you should keep it moist to increase the hydrolysis.

>>2748136
I hope the best for you but you can probably expect significant cracks come spring or summer

>>2745996
It's fuked. We pour self leveling all the time at work. Needs to be clean warm and use lots of primer. Don't pour before primer is dry or it will make soft spots or flake when weight is apllied. Pour when it's cold and it takes to long to cure and becomes soft sand.

>>2748348
You really should not be posting. No offense but you have no idea what you’re talking about.

>>2748457
Them thars fightn werds mister

>>2745996
Just keep it heated continuously from now on. Either it's fucked or it isn't, you'll only know after at least several days. Given that it's already in, there's no benefit in pondering over it. If it's still crumbly/sandy after a week, then it's probably fucked. If not, wait a couple of days more for good measure and tile over it.

2% chloride next time

Well I just scratched it again and its sandy.
Im going to go ahead and tile the floor. I think the adhesive will help hold the concrete.

>>2749581
Enjoy your tile cracking in a month because you were too retarded and impatient to let your base layer cure properly.

>>2749582
Hey I have an idea
How about you open the front door go outside and play hide and go fuck your self

>>2749584
Fuck me yourself you coward

>>2749591
Ok once im done with your wife, mother and daughter

>>2749581
You can use uncoupling membrane if you’re worried about cracking.

>>2749584
Oh, I see, it's not your house, you're playing flipper faggot and want to do things cheap and retarded and you don't give a shit if it fails for the retard that buys it.

>>2749606
Yeah like you cry baby

OP here
Nice try jerkoff.
Its my thread, period. Let it die im pissed off

>>2745996
In my experience, it takes a lot longer to set, but as long as it doesn't freeze, it should be ok. Whether or not it'll be as strong, I can't say. You're an idiot for not reading the instructions/getting a heater/picking a more suitable product.
As to putting another layer on top of a fucked first layer... Do I really need to tell you?

>>2750048
Mind your own business dickhead. I got your idiot hangin bitch. The outer layer sealed the deal, looks perfect. Its as hard and ready for tile

>>2750066
what is your endgame, false flagger?

Tile is done, thinset is setting.
Thanks for the input fellas and eat cold dog shit to the troll that tried to derail my thread

I'm looking for a concrete simulate to lay over a plywood sub floor. Just looking for the effect, I doubt the floor is strong enough to handle the weight of real concrete.
I can find vinyl tiles as big as 32x32" but would prefer a single seemless sheet. I found one vendor with linoleum sheets but priced at $6/sqft, very high for linoleum. Anyone know any vendors that might have what I'm looking for?

>>2749645
member old /diy/ before the trolls found it, everyone was nice and helpful and nobody could spell for shit but it was ok? I member.

i did this before...it seemed ok for a few weeks until it started crumbling to pieces. we rented a concrete grinder and had to epoxy over it afterword

>>2749631
*Maybe you should practice your English a little more, spic.

>>2746301
yes there is
it's quite important to be mean

>>2750318
The first five minutes after /diy/ got created? Sure, it became more bitter, but it was never all nice and helpful.

>>2746928

Why should anyone expect it to be nice when some faggot thinks baby speak is cool (member? is he fucking 5?).

>>2750441
You sure do cry a lot.

>>2750526
Its ole man grammar nazi

>>2750441
Ok, boomer.

You should be fine eventually. However, the cure will be shitty and long-term it will show you fucked up. Perhaps you can put a skim coat or rent a time machine and go back to before your mistake.

>>2750386
Oh look, someone who hasnt been here very long.

>>2750615
I already tiled the floor Mr. R. V. Winkle

>>2750650
I swear to god if YOU TROLLS DON'T STOP RUINING MY THREAD I'LL!!!!!!!!!!!!!!!!!!!!

Ok the floor is starting to crumble. It looks like the salt flats. Im hoping it will flow out and harden

Op here. So it's basically crumbling away anywhere I walk. You think it's safe to just tile over it? Will the tiles keep it together?

>>2745996
Have you thoroughly soaked the slab before pouring your concrete?

Actual concrete inspector here. Concrete will be ok as long as it didn't freeze. The strength comes from a process where tiny crystals form in the mix locking everything together as it dries. They will still form in cold weather just not as fast. If I was OP, I would ensure the slab was constantly moist for a period of at least 7 days, mist with a garden hose every day, if it the mix dries out too soon while the weather is cool you will not get as good of crystal formation.

Whats with these fucking trolls.
My floor is drying / curing nicely. I appreciate your advice diyrs

>>2745996
Run a couple of fan heaters until it cures maybe?

It probably shouldn't be beyond repare.
Like fr it should just curious after a longer time.

So ive been running the heaters all night.
Its right at 100 deg in there. Ill keep this up until sunday. Jeez kerosene is expensive I’ve already burned close to 30 gal

>>2753103
How stupid are you OP ?
The shit is toast. You have to be the dumbest anon in the history of diy

hey guys update, I put 5 heaters and the temps are about 180f, it's a bit hot in there but will probably help the concrete dry, house is smoki a little, so i clogged the sinks and ran water, nice and wet now
softened teh concrete right up and now i can comfortably lay in it, like a waterbed very nice
Also painted over the concrete with lead paint cuz lead is a metal and metal is hard it will keep it together
im a bit dizzy and sleepy now so i will take a nap here on the floor
thanks 4 all the hleps u guys are grate

>>2753133
Whats your end game mister ?
