I am doing a quick fix on an existing plywood, unfinished floor. I need to fill the gaps between boards before staining, then applying polyurethane.
I have plenty of Minwax Stainable Wood Filler to complete the job, but have read horror stories from others who say it is not as stainable as it should be. I have also read that some use it for their floors, though the container states "Not For Use On Hardwood Floors". Since plywood is not hardwood, does that statement still apply?
Since I have the MinWax filler already, I wish to use it, but if this isn't a good option, can you please suggest an alternative. I have heard that FamoWood latex filler would be a good choice. Any comments on that product for this use would be appreciated.
