We recently had the basement drain system replaced in our 1930s bungalow. This required removing sections of the concrete floor and filling the parts that were removed with new concrete when the job was finished. The old portion of the floor has several layers of paint that have been applied over the years.
Do I need to seal the new concrete portions? Appearance does not matter. There are no plans for renovating or installing anything over this floor, as it is the laundry area of the house. I only intend to put a few rubber area mats on it to stand on.
If sealing is recommended, should I use a sealer or a paint, and if so which one? I think epoxy basement paint is overkill for this situation, and I'm worried about the toxic fumes from these paints. I saw GBS Penetrating Sealer recommended on another forum, but I am fine with leaving the floor as it is if that's a viable option. However, if some sort of sealing is required I'd like the least invasive option.
