Two years ago we had wooden flooring installed. We had the wood sit out for 4 weeks to acclimatize as much as possible before we installed. About 6 months later (fall) we started to notice gaps between some of the floor planks. Since then they haven't gotten any larger or smaller with some being 1/8 of an inch. We ran humidifiers for a few weeks hoping that the humidity would help, but this didn't do anything - we are in Colorado.
I have looked around for a wood fill, but there doesnt seem to be anything like that on the market for larger areas. I recently bought some stain to stain in the gaps and try to reduce the appearance of the gaps - the floors are dark stained. But the gaps are still visible. I also just bought some dark caulk which I read helps, but wanted to get some opinions first before I start caulking the gaps.
I am hoping for a product that is easy to apply and fills the gaps - something similar to a wax type product that you can apply with a putty knife. Any ideas would be appreciated..!
