Tiny hairs embedded in finish

Q: We discovered under layers of vinyl that our 100 year old kitchen has a Douglas Fir floor. We had a floor man refinish with no stain, 3 coats of satin Bona varnish. The 3rd coat ‘bubbled’ in an area and so he came back to sand. He used paint thinner to eliminate any possible contaminates, then re-coated. Continue reading Tiny hairs embedded in finish

Over spray from house cleaning products contaminated floor job

Q: I’ve been a wood floor guy since 1990. Owned the business since 1995. In my years I’ve seen it all, but here’s my issue – My client has a floor finished with poly and wanted a new top coat. He was informative and knew what the existing finish was and that it had never been cleaned with anything other than water with a little vinegar. I didn’t worry about any oil or another cleaner that leaves an incompatible residue. (I should have.) Continue reading Over spray from house cleaning products contaminated floor job

A bad refinishing job by a professional

Q: We recently had our red oak flooring sanded and finished. I installed new in three rooms. The dining room and foyer was installed 25 years ago when we built our home. The person we hired claimed 20 years of experience. After all was done and we came back home we were disappointed with his work. The old flooring had dark and light patches. The perimeter of the room was darker than the field. Continue reading A bad refinishing job by a professional

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. Continue reading Widespread peeling or flaking

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
