Follow these steps if you need guidance to revamp your scratched floor. With sufficient research you can do this job yourself.
Thoroughly clean the floor
Tackle the job with hardwood floor cleaner or a solution of 10 parts water to 1 part vinegar. Dry the floor with a towel wrapped mop head. Be sure to close the doors and windows to prevent the dust from going through the house. This can also be done on laminate flooring but take care to treat it gently.
Prepare the perimeters
Sand the outer edge by hand and any parts that are difficult to reach with the sander using 180-grit paper. Sand just over 10 cm away from the skirting board until a fine powder forms.
Remember that all floors need maintenance. Suppliers like http://www.woodfloorwarehouse.co.uk/laminate-flooring/cheap-laminate-flooring.html will be best at advising you on maintenance when you initially decide on your flooring.
