Brazilian Cherry darkened in under 2 months leaving lighter spots where furniture was

Q: A contractor just installed around 800 square feet of 3/4 prefinished Brazilian Cherry on our first floor. It looked very good until we unstacked our furniture today. The furniture had been sitting on top of flat pieces of card board for about 1-1/2 to 2 months as the contractor finished the floors. Now we find that our floors look like they got a sunburn with band-aid marks all over them! Continue reading Brazilian Cherry darkened in under 2 months leaving lighter spots where furniture was

Spots where I used oxalic acid (wood brightener) are lighter after finishing

Q: I have just completed refinishing a 55 year old white oak floor. To remove some water spots I used oxalic acid (wood brightener).

Pale spots on pine floor

Q: I’ve just had a 100 yr old Kauri pine floor sanded and finished with a 2 pack water based polyurethane. The sanding looks fine and the finish is great, except that there are pale spots / blotches evident in the wood in a number of areas, some quite large, some small. These were evident after applying the sealer, but I was assured would disappear with the urethane finish (4 coats) but they haven’t, and then I was told this sometimes happens with Kauri pine.

Bleach like spots on wood floor

Q: I have pine wood floors coated with polyurethane. They are about 80 years old. Some of the wood, usually under a bed or throw rug, has lost it’s color in spots.

Dark spots a sanding issue or resins?

Q: Before applying finish to my fir flooring, I want to know whether my fir floors have been properly sanded. There are numerous areas of darker color, for example, a 3-inch band of darker wood parallel to the wall and offset by about 6 inches. It seems like this strip simply was not sanded as much as it should have been. Other dark areas with pretty well defined edges are in the middle of the floor. Continue reading Dark spots a sanding issue or resins?
