I am refinishing some old tongue and groove pine floors. Would you recommend your Timbermate product to fill gaps between the boards? The gaps are up to 3/16 inch (most are 1/8 or less). I plan to apply a water-based finish to the floor after the gaps are filled. If not, could you recommend which other product I should use. It is a small room of about 130 sq. ft. in an old farm house. I am using this small room as a learning and testing project before doing some of the other rooms.
