Tongue and groove floor gaps
We had a 1 1/2" thick tongue and groove floor installed for the upper level of our cabin which also serves as the ceiling of our main level. It looks great on the main level but upstairs, there are wide spaces where the tongue and groove meet. The boards weren't perfect and it rained and rained the summer we installed them before the roof was finished. It is so hard to sweep dust, insects, etc. out of the grooves. We haven't put a finish on it yet. Everyone we have asked have said there is nothing we can do. We know that it adds to the character of the floor to have some spaces but there are way too many. Does anyone have any ideas of something we can try to fill the grooves before we put a finish on the floor? We're ready to try anything and if it doesn't work, we'll have to put a new floor over it.
