- I had the hardwood (oak) floors in our house redone last November.
- Previous owners had already done at least one horrible job on the
- floors and possibly two. In several places, they had sanded (heavily)
- perpendicular to the grain. There were also some spots with water
- stains that had developed since the last refinishing job.
-
- Because the previous sanding had left scratches that were quite deep,
- the floor-man said, it would not be possible to get them all out
- without sanding down to the tongue and groove joints. After finishing
- the floors, some of the scratch marks are still visible. However,
- this problem was something to be expected.
-
- The real problem: The new finish did not seem to take. The floor-man
- used Gray Seal `Gym Finish', which is an oil-based urethane. Wherever
- the grain was pronounced, the wood seemed to absorb much more of the
- urethane than other areas. Also, there were areas with a waffle
- pattern of glossy and dull finish in about 1-inch squares.
- Originally, the floor man put down two coats of the gym finish.
- Because of the unevenness, he then put down a third, with only slight
- improvements.
-
- The original plans were to put down a different finish, an `epoxy
- coat'(*). However, the floor man said that because it was so cold, this
- was unlikely to dry properly. (The problem here is that we couldn't
- have the heat on because it would blow dust around which would then
- settle in the drying urethane. So,during the nights, I set the heat
- up to about 80, then turned it off about an hour before the workers
- arrived.
-
- The proposed solution: The floor-man tried putting some of the epoxy
- finish on a test patch where the first finish looked bad. It looks
- OK. So we are thinking of putting a top-coat of this on the floors.
-
- The question: Is it truly OK to put this new type of finish on top
- of the old finish?
-
- Answers by e-mail to dunne@math.okstate.edu would be much
- appreciated.

- (*) I believe Epoxy Coat is a brand name. I do not know whether this is
- really epoxy-based. No one in town carries the stuff; the floor man
- orders it directly from a distributor. So I am unable to check it
- out at the stores.
