How do you install tack strip on concrete?

there are special hardened nails that bite into concrete

ask at any home improvement center, they'll show you which to use ---- You can also, if the floor is old or the nails are not going in easily, glue tack down. Always try to nail it first, but if this isn't working, good old fashion Liquid Nails works just fine too. This method is advisable if you have old 9" vinyl tile. They often contains asbestos which is best left undisturbed.
