/diy/ - Do It Yourself

I poured self leveling concrete yesterday but the room is around 3-5 degrees celsius and I am unable to warm it beyond that right now.
The bag says it has to be at least 10 C.

Is it going to be fucked?

Will it even cure?

I scratched the surface with my fingernail and it comes off like sand. Maybe that's because it's only been 24 hours, but I'm scared that I permanently fucked it up.

Lets say it's not as strong as it's supposed to be, can I put another 1/2 inch layer of self leveling in the room at proper temperatures to improve the strength of the floor.
I am going to be tiling the area and putting a bathtub on it.

I'm going to install vinyl plank over existing tile throughout my 600 sqft condo. I don't want the grout lines to show through, so I'm going to use self leveling concrete throughout the entire place. I am buying an industrial drill, mixing attachment, and 8 gallon pan. Has anyone done this before? Am I a retard for trying to do this on my own?
