What causes white spots on our floors?

Q imported from our old site, Face Lift Floors: I recently had the hardwood floors in my 1950’s house professionally refinished (sanded, stained, and polyurethaned). The floors were previously covered with carpet and had some stains, thought to be from carpet cleaning chemicals. A couple of months after the floors were refinished, white spots on some areas of the first floor started appearing and keep on getting worse. The floor is above a crawl space. The contractor said he thinks it’s from moisture; however, not all areas are affected and it seems the white spots are in the areas that were previously stained.

Light (UV?) areas appeared on floor after applying poly

Q: I have just resanded and finished my 15-20 year old red oak floor. We stained it a week before putting on a water based poly, and it looked great before we applied the poly. Once we applied the poly finish, light areas appeared on the floor. Continue reading Light (UV?) areas appeared on floor after applying poly

Dark round pigmented areas

Q: I have sanded my old pine floor boards and finished with water based lacquer. Around the floor nails I am noticing dark round pigmented areas. Is this normal with reclaimed floors or is it because I used water based lacquer? I think maybe this is oxidation from the nail? Continue reading Dark round pigmented areas

Gradually stain area until I can get it to match?

Q: We stripped and sanded our pine floors in our 100+ yr. old cottage. Long ago, the previous owners painted around the large throw rug in middle of room. Eventually it sat for decades under wall to wall carpeting. Continue reading Gradually stain area until I can get it to match?

Rug outline on newly finished floor in short time

Q: I had my wood floors refinished 2 months ago. I waited 3 weeks to put furniture and rugs down on them. I was vacuuming last week and rolled back the rug to vac underneath and found that there is an outline of the rug on the refinished floor. I don’t have a skylight or large windows, and it’s only been a few weeks since the floors were done. Continue reading Rug outline on newly finished floor in short time

1′ x 1′ Area where the wood is white.. or lacking stain

Q: I recently bought a 107 year old house. Upon ripping up the carpet I discovered beautiful, finished hardwood flooring. However, it seems (also told to me by seller) that the previous tenants (was a rental) had a dog (were not suppose to) and by the smell and sight, this dog went wee in the house. Continue reading 1′ x 1′ Area where the wood is white.. or lacking stain

Worn foot path won’t sand out

Q: I first did a spot sand on the worn foot tracks in a hallway of a pine floor and the sanding looked pretty good. Then it was decided to just sand the whole hallway for fear the spot sanding would not match the rest. After doing a full sanding and cleaning up the excess dust, I applied a natural stain to the floor. As the stain dried, you can still see where the worn foot tracks were prior to sanding. Continue reading Worn foot path won’t sand out

Manufacturer claims stains caused by hardwood floor cleaner

Q: We had an engineered wood floor in American Cherry finish installed throughout the Living, Dining, Family Rooms and Kitchen (1000 sq. ft., open concept) about one year ago. Approximately 6 months ago we started to notice dark stains appearing along the edges and ends of the planks, which we assumed to be water stains. Continue reading Manufacturer claims stains caused by hardwood floor cleaner

Yellow patch appearing on pine floor

Q: In our bathroom we have 30 year old pine floorboards that had previously been stained and varnished. I stripped the varnish off and sanded to reveal a nice distressed look. Then I used Sadolins floor oil. The result was very good. However, a month later I have a yellow patch appearing (about 8 by 8) and I can’t get rid of it. I’ve tried sanding, but the yellow only seems to get brighter. Continue reading Yellow patch appearing on pine floor
