need some help with old flooring

[cange]

Got a question...I've got an old farrm house.156yrs old and I want to sand and refinish the orig pine floors. However , there are some considerable gaps petween the planks. Is there a way to fill them or maybe chinker them? I was thinking of maybe polyester....I dont know. We did the floors in the b-room but did'nt have this issue there. any help would be appreciated. thanks.

In my honest opinion I would say leave it alone due to the fact that if you fill the gaps over time they will crack. Then you will have chunks of filler comming up out of your floor. Any wood floor expands and contracts this movement no matter what will make it crack some day. I have a neighbor that had gaps in his floor. They were about 1/8" to maybe 3/16" he did not fill them when he had his floors refinished and I think they look good. It kind of adds character to the floors. This is just how I feel about it you may want to take your chances. One other thing older homes many times have joists that span to far or are spaced wider than 16" centers. This also will cause more flex to the floor that will cause the filler to crack. Take care Dale
