Hardening a garage floor

This question was asked by – Grant Wilde Hi, looking to seal a residential concrete garage floor which is constantly dusting and so soft it can be scratched easily with a metal object or even the sole of my shoes. Ideally it could be applied quickly and easily to half the garage at a time, so I don’t have to pull all the stuff out at once! Would the nano-lithium be suitable? Thanks. No the Lithium densifier is for use when polishing, it will have little affect on a normal concrete slab. What you will be best of doing, if you can, give the floor a really good jet washing to remove the loose surface material and then seal the concrete, this will stop the surface from dusting again.
