The basement floor of my 50-year old house was covered with asphalt tile about 45 years ago. It has been covered with carpeting most of the last 40 years. A recent power outage and torrential downpour required removing some of the carpeting, in my workshop area. I would like to keep the 20' x 20' uncarpeted area uncarpeted.
The old floor is firmly attached to the underlying concrete, and is in pretty good condition except for surface dirt which I am pretty sure can be easily removed with a stiff scrubbing brush. My problem is that the tiles have shrunk over the 40 years and now there are gaps around each tile. The max gap is under 1/32=94. I would like to figure out how to fill in the cracks/space between the tiles, bringing the filler up to the level of the top of the tiles so that the =93cracks=94 don't fill up with the usual workshop floor dirt. Time to do the work is not a big issue, as I am sort of retired.
All suggestions will be considered.
