Things you SHOULD NOT expect from a wood floor finish !
1. A table top finish. Each piece of oak flooring sands differently depending on its grain type (plain or quartered) making it virtually impossible for a completely flat surface.
2. Dust-free finish. Since your floor is being finished in your home it is not possible to achieve a "clean room" environment. Some dust will fall onto the freshly applied top finish.
3. A monochromatic floor. Wood, as a natural product, varies from piece to piece. Remember it is not fabricated -- it is milled from a tree and will have grain and color variations consistent with the grade and species of flooring selected.
4. A floor that will not dent. In spite of the term "hardwood", Oak flooring will dent under high heel traffic (especially heels in disrepair). The finish that is applied will not prevent the dents.
5. A floor without cracks between the boards, or within the parquet pieces. Although your new floor may start tight together, as a natural product it will continue to absorb and release moisture. This natural process will cause the flooring to expand and contract from season to season -- resulting in cracks between some of the pieces in your floor. Some stain colors, such as white, will show this process more than others. Understand that furniture, cabinetry, doors, etc., are fabricated in a factory under ideal conditions and that they contain 1-10 different pieces of wood. Your floor is fabricated in your home and is made up of 300 to a thousand individually different pieces. And that your floor can never be duplicated -- a truly custom floor of your own!
After the job is completed, go over the job with the estimator and/or job supervisor.
Maintenance procedures should be reviewed, along with proper protection of furniture (place protection under legs) before it is placed onto the new wood floor and items of concern should be addressed.
Remember, wood floors are an investment, proper maintenance will give you years of beauty & enjoyment!
