I also have Hartco oak parquet installed in my entry hall. The parquet tiles I have are 12x12 in 'Frost White',a whitewash color which still looks good where it wasn't exposed to light. The oak is solid 5/16th" thick. This whitewash color has been discontinued. The flooring dealers tell me that no one wants to refinish wood flooring in white wash stain anymore...too much trouble. The Frost White that Hartco used was beautiful.. a very thin coat of whitewash and a hard polyurethane finish. I discovered that the actual wood wasn't darkened, only the urethane finish had yellowed. I applied some Citrus strip to a scrap of the tiles. Underneath the finish, the wood was still a nice new looking light oak color.
I would like to put in more parquet tiles in the adjoining hallway in the 'natural' oak color that Hartco carries now. I've heard of a process called "screening" which removes only the top finish layer from the wood and very little of the actual wood layer. I thought I might get the thin layer of polyurethane off the wood, both the old and new parquet. I would then apply a thin coat of whitewash stain, or pickled oak stain, to both old and new parquet tiles. Then apply a final coat of waterbase polyurethane. If I can't find anyone to whitewash and finish the floor I may try it myself. I'd use a professional to screen or lightly sand the floor first.
Does anyone have ideas of info on screening of wood floors? The brochures of wood flooring companies recommend this process to renew the finish on lightly worn wood floors. Thanks much!
