After the finish was applied, dark spots appeared

Wednesday, April 23rd, 2008

Some friends of ours had their hardwood floors refinished by professionals. The floor looked perfect after sanding, before the finish; but, after the finish was applied, dark pet spots appeared. I am refinishing my floors and I don’t want the same thing to happen. My sanding is complete and floors look good now, but is there the chance that the same will happen? Or was something done incorrectly to cause this to happen to our friends floor?

Stains that won’t come out

Saturday, April 7th, 2007

I just sanded an old oak floor. There was old carpet over it. It was very filthy. I sanded with 20 and 36 grit, but there are stains in wood that won’t come out. How can I get rid of them?

I’m noticing new dark/black spots on my hardwood floors. Should I be concerned? What causes this?

Dark stain circles on very old floor

Saturday, April 7th, 2007

I just moved to an old house from the 1800’s. The wooden floor is very old and has very dark stain circles on it. I have tried getting it off with soap and water. It wont come off. I was told I can’t sand it because it is too thin. Is there a dark enough product that can cover it to still make it look like wood, or is there something that can take out the stain?

Is there a product that will remove pet urine stains?

Wednesday, March 14th, 2007

Is there a product that will remove pet urine stains (black discolouration), which were found beneath carpet underlay? The floors are 51 year old oak hardwood, and large areas of the dining and living room are affected.

Stain and dark pet stains

Friday, March 9th, 2007

I am refinishing my 45 year old oak floors. When I removed the carpet there were 3 dark stains. I figure it is pet urine. Sanding is finished, but the stains are still visible. If I apply a darker (perhaps cherry oak) stain, will it hide the urine stains or will they just get darker? Could I apply less stain to the spots to try to even it all out?

Black stains not fully sanding out

Monday, February 5th, 2007

We have discovered many black stains on the hard wood floors after we pulled out the carpet. We tried to sand them out. While some got lighter, others did not. There seemed to be a smell of urine during the sanding, so I’m assuming that these stains may be from pets. Is there anyway to get these black stains out?

Black stains did not come out when sanded

Monday, February 5th, 2007

I just had older Oak floors refinished. They are approximately 40 years old. There were black stains in the hall way that would not come out when sanded. We kept the floor stain the same as the original but the black stains look horrible. Would you suggest restaining the floors a darker color so the darker stains won’t show as much? We are in the process of fixing up this house to sell.

Pee peels

Tuesday, November 7th, 2006

My dog peed on our floor and we did not notice this until the next day. After cleaning up the mess, I noticed that the finish had lifted and peeled on one side of the wood slat. The wood in not discoloured but you can see where the finished has peeled. Can I try and apply polyurethane to that one spot or is it better to sand the whole slat and then apply polyurethane to the whole slat of wood?

Re-dampening urine stains

Wednesday, September 27th, 2006

I have old urine stains on my hardwood floors. There is no odour or buckling, just dark marks. When the moisture is high these areas become damp. How do I stop this?

Urine stains

Wednesday, August 30th, 2006

We have recently removed carpet from a house that I have lived in for 2 years. The carpet had been down for 10+ years and it was used by the previous owner”’’s dog as a bathroom. Under the carpet is hardwood, but is has urine stains. The carpet pad was stuck to the floor and some of the staples were rusted. Upon removing the pad and scrubbing the floor, there are light stains left by the mess. What do we need to do or use to restore the floor to the way it should be–pretty and unstained?

Dark watermarks

Thursday, May 4th, 2006

We took carpeting up from our bedroom which has hardwood floors underneath. When cleaning the carpet from pet urine there are severe dark watermarks. Is there a way to lighten the marks before sanding and refinishing?

Small pet stains on floating floor

Friday, April 28th, 2006

I found your web site while searching out how to manually try and fix several pet stains my dog has made on my hardwood floors. I have floating hardwoods that I believe were put in on top of a tile floor. Unfortunately the dog has had a couple of accidents in his old age. There are three none bigger than the palm of your hand. I don’t want to have to replace the floor if not absolutely necessary (I’m not sure I could even find replacement boards since the floor was put in prior to my owning the house). Is there anything I can do cleaning wise to try and pull the stain out of the wood? I did read on your site one of you visitors tried hydrogen peroxide and was able to bleach the stain out of their wood but I’m not sure if that will work for a pre-finished floating floor systems. Do you have any suggestions?

Hydrogen Peroxide to remove black stains

Wednesday, February 8th, 2006

I recently removed 30 year old carpet from hardwood floors. I discovered some spots that were dark black (I am guessing pet stains). I applied hydrogen peroxide to them and after a few treatments, the black stains lifted and the wood was left white. I chemically stripped a 3 X 1 rectangle around the white spots so that application of stain would be even and not spotty. My problem is that the white spots in the wood are now not taking the stain as dark as the chemically stripped areas. Is there anything I can do?

A few small stains

Tuesday, September 20th, 2005

We have a few small stains on our hardwood floor. They are either from water or from paint. Can we sand and recoat just those small spots, or would we have to do the whole floor?

Pet stains and prevention

Saturday, September 17th, 2005

I’m planning on re-finishing my hardwood floors after discovering black, and I mean black, pet stains. I’d had some boards replaced before for the same reason, and thought I solved the problem with the dog, but not so. I didn’t have the floor resanded and refinished, then, just boards being replaced after being taken from another room.

Paint and putty

Sunday, July 31st, 2005

I have a friend who is in the final stages of building her home, she was basically her own general contractor. The hardwood was started before the drywall was up so when the drywall was installed and the ceilings textured a lot of the paint and putty ended up on her unfinished hardwood. We know that scraping and sanding will take care of the putty but someone has told her that the paint and primer will be difficult to remove since it has probably soaked into the wood. It’s not oil based paint or primer so we’re hoping that soap and water will do the trick. Have you found that this is a problem and are there any suggestions you can give for cleaning to floor in preparation of finishing it.

Finish has worn off the floor

Saturday, July 30th, 2005

I recently removed my living room carpeting, as it was filled with pet stains. The hardwood floor underneath was for the most part in good shape. There are a few areas where the finish has come off the hardwood floor. The floor boards are in great shape, no warping and the floor cleaned up nicely. However I want to know if I can just refinish these areas of the floor if there are no deep stains or smells. Can I re-stain these areas of the floor without having to refinish the entire floor?

Severe black spots

Saturday, July 30th, 2005

We just pulled up our carpet, and there are severe (water) black spots.

Pet urine stains

Saturday, July 30th, 2005

We just purchased a home with hardwood floors throughout; however they all have dark brown stains. We do not know if it is from water damage or from pets; my husband think they are urine stains from the previous owners pets. We would love to keep the hardwood floors and are hoping that the stains can either be removed or be covered. Can you please tell us what we could do to save our floors? Can we stain them darker to hide the stains if we are unable to remove them?
