Widespread peeling or flaking

Q: We need your help. We bought a new house in September 2016 and had the floors refinished before moving in. The floors were in different conditions around the house. The first floor was stained dark, the second floor was blonde (probably the original finish since it was previously carpeted) and the kitchen was pre-finished wood according to my contractor and the floor guy.

Would turpentine peel floor finish?

Q: I run a painting business and have several times used mineral turpentine to clean paint off wood floors with no problem occurring. We’ve recently been blamed for a water-based floor sealer peeling off in a small area, even though it was used throughout the whole flooring. I was wondering if the mineral turps could’ve been the cause of this?

Finisher seems to have not used the necessary cross linker of two-component waterborne



Q: I work at an event venue. They recently got a new floor installed. The new finish scuffs and absorbs stains.. the word I feel is best to describe the finish is ‘raw’, almost like a piece of pottery that hasn’t been kiln-fired. Continue reading Finisher seems to have not used the necessary cross linker of two-component waterborne




Lighter shades in the middle of refinished floor



Q imported from our old site, Face Lift Floors: We have had our floors professionally refinished (white oak). There was no stain applied, but an oil-based sealer and two coats of waterborne finish. Most areas look great. There are some areas that have a noticeable color shade difference  – For example, fairly long strips where a hand sander was used to remove the prior finish along with a wall edge. Also a few areas mid floor. Continue reading Lighter shades in the middle of refinished floor




Did not buffing between coats cause this?



Q imported from our old site, Face Lift Floors: We have applied polyurethane to my hardwood floors. After the fourth coat was applied the sheen on the floor dulled. There are random spots here and there that are still glossy, but the rest of the flooring is duller than it was after the 3rd coat. We hadn’t been sanding the floors after every coat, only after the first coat. Continue reading Did not buffing between coats cause this?




Finish peeling off because there is wax in the grain



Q imported from our old site, Face Lift Floors: I sanded a 980 sq.ft. job and when I coated the floor (oil base/satin) the finish started flaking off the floor from the grain. I have had this problem one other time in the 4 years that I have been sanding floors. I know that the problem is wax in the grain of the wood, and I also know that even if I sand the whole floor again the same thing will happen in the same spots (been there done that). Continue reading Finish peeling off because there is wax in the grain




Debris in finish, in just one spot



Q imported from our old site, Face Lift Floors: At a doorway, my urethane finish has lots of debris in it. It appears it was not vacuumed or tacked in this area prior to finishing. The doorway leads to a bathroom and it appears the grout crumbled slightly and got into the finish. Continue reading Debris in finish, in just one spot




Small scratches on tender coat?



Q: My problem seems to be a tender coat. I have two coats of Poloplaz Primero and after almost 3 weeks of cure, I am getting small scratches in the topcoat. Of course because it’s such a wonderful product, there is very little information on the Internet about any scratching of Primero. It really is a great product. Continue reading Small scratches on tender coat?




Cracks between boards shinier than floor after second coat of poly



Q: After our second coat of satin poly there are shiny places along some of the cracks between boards. We waited 24 hours then used a pole sander with 180 grit screen to sand after the first coat. My theory is that these are low places where the poly pooled. Continue reading Cracks between boards shinier than floor after second coat of poly
