ᐅ Open-Pore Prefinished Hardwood Flooring – Features and Tips?

We have planned a multipurpose room on the ground floor for sports, guests, and a desk area.
Before now, we had no experience with hardwood flooring, except for some research (including here in the forum), but no personal experience.

We have now received a sample of an oiled, open-pored two-layer bamboo parquet.
We like the texture; the tone could be a bit darker, but maybe a mid-tone (honey-colored) will work better for about 14 sqm (150 sq ft).

Now to my questions:
1) Open-pored oiled: how does it perform with moisture (not wet), for example during sports activities... barefoot?
2) Color: is it possible to darken the tone with oil? In other words, are there hard oils with color pigments? Or does the wood naturally darken over time?
3) Cleaning: can it be cleaned with a damp mop?
4) Chair casters: how does open-pored parquet hold up? Is it prone to scratching?

The underside of the carrier layer (5 mm (0.2 inch)) has grooves, about every 3 cm (1.2 inches) approximately 2 mm (0.08 inch) deep... The parquet is supposed to be ideal for underfloor heating (glued installation).
5) How do the grooves affect this? Wouldn’t they create air pockets when glued that reduce heat transfer? (We plan to glue/install it in an elevated level).

We have also seen parquet at specialty stores that already include insulation. Is that necessary with glued installation? Do you then glue the insulation as well?

P.S. The material is 10 mm (0.4 inch) thick, 5 mm (0.2 inch) upper layer, 5 mm (0.2 inch) carrier layer, which is also bamboo but appears to be cross-laminated.

Thanks in advance for your answers.

Ask about steamed bamboo. It is darker due to the heat treatment. Light bamboo tends to turn yellow in the sun.
Desk chairs can be hard on the floor.

We installed dark bamboo flooring in the living room, and now we know that anyone allergic to visible scratches should avoid bamboo.
We like it and would choose it again.

When installing a natural product, wear and tear should always be expected.
Regarding parquet flooring, scratches are unavoidable, although bamboo is considered one of the more durable woods. Personally, we prefer living with a "working" and natural floor (currently in our living room, basement, office, and two children's rooms) rather than what I consider a musty carpet. Anyone who has cleaned a carpet with wet cleaning after some time knows what I mean.
Now, to answer your questions:
1: completely unproblematic
2: either choose a suitably darker wood or oil the floor—light wood usually darkens over time, while dark wood tends to fade
3: we sweep daily and mop once a week with a damp cloth
4: it depends on the hardness of the wood; our Wenge parquet doesn’t care about a chair, but in the office, I have a transparent desk chair mat on the maple parquet to prevent indentations over time
5: the grooves get filled with adhesive (which is applied with a notched trowel and therefore also contains grooves)

Insulation under glued parquet flooring is pointless. However, for floating installation of parquet or laminate, impact sound insulation is necessary.

I have to say: bamboo is not wood. Bamboo is a grass.

But honestly, it was sold to us as being harder than oak. That is definitely not the case.

True, it really is grass! Shame on me.

It's a pity that the bamboo flooring is so delicate in your case. However, I only know bamboo from the flooring showroom, and there it felt very hard (nail test passed without any problem).

A fingernail is also significantly softer than a chair with a person sitting on it.
