Scratches that don't penetrate through resilient flooring often can be sanded out (sanding creates fine airborne dust, which may be hazardous if the flooring contains asbestos so have a sample of your floor tested first).

If you do sand, use a medium-grit sandpaper followed by finer grits until the scratch disappears. Apply floor wax to restore the shine on the buffed area.

Blisters in sheet vinyl can be reglued. Make a knife cut along the edge of the blister, just large enough to let you work glue into the void. Use an artist's brush to apply contact cement on both the subflooring and the blister flap.

Let the glue dry until tacky and then lay the flap down and place a weight on the repaired area for several hours.
