ᐅ Basement without additional floor covering / cleaning of the concrete slab

Dear Forum,

After two years of planning, the construction of our house has finally begun.
Our basement will be used exclusively for the laundry room, storage, pantry, and utility room. Mainly for cost reasons, we have decided to forgo heating, insulation, and plastering or painting in this area.
However, we are now wondering if it was a mistake to skip the screed and an additional floor covering. Does anyone have experience with a basement where the bare concrete slab forms the floor? Is it practical to clean this concrete surface regularly by damp wiping and removing coarse dirt?

You can see how level it is when you set up the first shelves. 😉

Once the walls are already in place, I definitely wouldn’t change anything like the screed now. Otherwise, all the heights won’t match anymore, and that really matters when it comes to the stairs.

Isn't there a special paint for that? Like concrete sealant, basement coating, or moisture-resistant floor paint… I have seen quite a few buckets of these at the hardware store. There must be something specifically designed to seal sandy concrete?!

Garage paint can be used. However, it is not any cheaper.
A bare concrete floor cannot be kept clean. Even vacuuming is annoying. Mopping is impossible.

Thanks for the tip. I just looked it up. Apparently, there is a concrete oil that is very effective at repelling dirt and water.

However, it does not fill uneven surfaces and is intended for polished finishes.
I don’t want to have to clean up spilled liquid detergent or broken glass with preserved food on the floor. 🙄 That really sounds like a reckless idea.
And an uninsulated basement? Is that even allowed, or do you insulate the ceiling?

I would recommend tiling the utility room to ensure it’s finished on time, and doing the rest later as a DIY project. Otherwise, cleaning raw concrete is likely to be quite unpleasant.
