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

Will my too shiny coat of polyurethane dull as it cures?

Q: Does poly finish become duller with time? My contractor did a patch in my oak floor and applied 3 coats of semi-gloss poly trying to match the old floor. The first two looked pretty good, but the 3rd (final) coat is really shiny. He claims that I just need to wait 30 days for it to fully cure and it will match. Does poly dull with time in this way?

Wood floor finish for a house on stilts

Q: We had a new white oak floor installed and used a Minwax stain that was tinted with white pigment (Sherwin Williams). The installer waited 48 hours after applying the stain. The house is on the water on stilts and heated, set at 60 degrees. He then applied 3 coats of Bona Traffic HD, buffing between coats.

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




Can I lightly sand and put an oil base poly over water base poly?



Q: I sanded old finish off my wood floors, then put a oil base stain on, and then put a water base urethane on. I lightly sanded the floor next day and put a second coat of poly on. Now I have a few spots flaking. Continue reading Can I lightly sand and put an oil base poly over water base poly?




Lighter look or deeper colour



Q: I have pine floors from the 30’s. I had them professionally refinished two times in the past. There is no stain and the poly wears away quickly. I recently sanded one room myself and applied oil based poly. It came out darker where I sanded one area more than the rest due to scratches and wear in that area. Continue reading Lighter look or deeper colour




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
