Why do my newly refinished hardwood floors have dents and bubbles all over?

Q. We recently had our hardwood floors refinished by a friend of a friend who said he knew what he was doing. The floor has dents/waves in it and the finish is not smooth but has small pimply bumps on it. Is there any way to fix this without refinishing the floor entirely? We haven't paid this "friend" yet - what should we do?
The dents/waves were not in the floor before it was sanded. Could the sander have caused them? Is there a way to fix without resanding all of the newly applied stain and polyurethane?

A. Those dents and waves are a direct cause of the belt floor sander being improperly used. If the belt sander is allowed to sit to long in one spot it will eat away too much wood causing dips and waves in the flooring. You will have to re-sand to fix this unless this guy ate to much into the wear layer of your flooring then you will have to replace it (this usually won't happen unless you've had your floors sanded several times before). From the sound of the pimply bumps you are either looking at particulate (improper cleaning before finish is applied) that has been finished over leaving a sandy like finish or fish eyes which can be caused several things. If it is just particulate that has been finished over this can be buffed out then refinished again after a good cleaning. If it is fish eyes in the finish they may be sanded out depending on their size. But like I said in order to fix the waviness you will have to resand anyway.

How To Remove Scratch of a Refinished floors?
Q. I recently had my 50+ years old pine hardwood floors refinished with 3 coats of oil based. Looks really nice and shiny. Now I made a light/clear scratch from moving furniture and I can't get it off by using an eraser or water+soap. Any other ways to remove a simple clear scratch/scuff from the top coat? Thank you!

A. Try a little bleach, don't pour it directly on the floor, put some on a towel, or sponge and a little elbow grease.

How to get paint off newly stained floors?
Q. Hello. I just had some floors refinished in a room I had painted. The baseboard got some floor stain on it, though. So, I put painter's tape on the floor in front of the baseboard. After I peeled the tape away, though, white paint had dried on the floor (small amounts, but they make the floor look like hell at the border). Does anyone have any tips to remove this little bit of paint? A razor does nothing and I don't know how to get off the paint without ruining the floor.

Thanks!
I should be more clear. The floor's stain is relatively new. As such, even though it's dry, it (like all new stains) "catches" the razor on contact. So, I can't make a smooth scraping motion over the floor.

A. you can try goof-off professional paint remover with a q-tip, available at any hardware store, but i suspect if its not budging with a razor that goof off might not remove it or might cause damage to the stain. goof off also removes urethane so be careful
