Can anyone tell me if this new mrsandless method of beautifying hardwood floors is effective? We have a 5 yr. old home with breakfast, kitchen, hall, and foyer covered in standard builders grade prefinished hardwoods where the previous owner's dog has scratched the finish all over. In addition, just the normal wear and wash has dulled the finish. We would like to have the floor restored to a more brilliant shine and finish. Any suggestions.

Hire an experienced, licensed, reputable local hardwood floor refinisher to do a recoat!

Would this be a recoat without sanding or after sanding. If without sanding would a recoat cover the scratches from a pet? Really appreciate your feedback. Thanks

It's hard to say. I think the scratches would still be slightly noticable in the right light if they are very deep. Very light surface scratches are usually covered and are not noticable. But dog's nail marks are normally a little deeper and the new finish will flow into them and you will still have a small impression. There are three ways to go about this:
1) a complete refinish where the floors are sanded down to the raw wood, re-stained and and least three coats of floor finish are applied. This will eliminate all surface flaws and the floors should look new again.
2) a recoat by buffing the floors with a electric buffer using fine abrasives and proper cleaning solutions. This cleans and conditions the floors to have an additional coat of finish applied. This will not address every problem such as dents, discoloration or deep scratches but it will make the floors more attractive and provide more protection. This is the method I employ when recoating.
3) a recoat by cleaning and applying a bonding agent. No abraiding is done with this method. IMO, this is the least preferable as it does not clean the floors and finish as well as using a buffer.
