Sad to say, you can't close those gaps. About all you can do is fill them with a good color matching filler, such as minwax or others. Do you plan on refinishing the floors, or are they prefinished? It appears the flooring was ill-trimmed from the mill. We catch and cull these boogers as we go. Nice firestarter, but no good to install.

If the floor still needs to be sanded and finished, they have a paste that you can smear over the cracks. Sanding removes all of the dried paste except what is in the crack. I don't remember the name of the paste. but most any store that specializes in wood floors would have it. On a finished floor you would use colored wood putty. If you can't find a jar of putty the right color, you might need to buy 2 jars and mix the 2 different colors together.

Thank you.

chandler, it is unfinished oak hardwood and I still have to sand it. I do not plan to stain it, just putting polyurethane coats on it.
I read that if I would fill those gaps with just a filler it will work its way out by contracting and expanding of the wood.

Is this freshly installed? If so, did you DIY or pay someone to do it?

Eh, if you'd paid someone to do this, I would make them come out and fix this.

If a constant temperature and humidity is kept in the home there shouldn't be any issues with the filler coming out. As far as I know the only time there is any danger if the filler popping out is when there are huge temperature or humidity swings - like an unlived in house.

Others may disagree, but I think that these gaps will be less visible once the floor has a couple of coats of finish on it. If you use a multi part epoxy finish (one that hardens by reaction, not evaporation) you should be able to float the gap. In turn you create a mirror finish that will tend to fool the eye into thinking it is part of the character of the wood. I don't think you could do this using plain floor poly. The pros mix there own.

Or maybe a combo of filler to match and epoxy to finish.
