gaps in wood flooring
We installed doug fir tongue & groove over a particle board base 12 years ago. Obviously, the wood was somewhat green, since there are now up to 1/4 gaps between the boards. Does anyone know if the cobblestone wood floor "grout" formula of 3/1 sawdust to lindseed oil would be a good filler and then of course seal it. I thought this would look better than the "rope" filler someone suggested. Also someone suggested Buthers' Wax, what is it and where could one get it? Thanks.
