My wood floors are from 1954. I just purchased the home and wanted to refinish the floors. The company's salesman/co-owner said there is 3 different kinds of wood and i don't know if that matters. The stain was put on yesterday there is a lot of uneven spots, blotchy spots. It looks very bad to me. I showed the other co-owner this morning. He said the will sand the dark spots to even them out then they will add more stains to the light spots.He also so that the sealer and poly will even out the stain.Is this true? I am worried that this will not look right. I am no professional but I don't know what to do. Does this need to be redone? Should they have used a pre stain/ conditioner for making the floors look even? The stain is sherwin williams brazilnut. I am worried I made a huge mistake.

Dark stains can be very pretty if done carefully. Finish will help even out the color variation and show more of the wood's color, too, so it will seem to lighten up.With extra care, steel wool, scraper and hand sanding, the floor could look much better. Scraping machine marks to blend, then hand sanding the scraper marks when they became apparent during the staining process should have been done before the stain dries for the easiest solution. There looks to be a lot of work to be done before the first coat of finish is applied. If areas are scraped to bare wood, then re-stained, the stain will need to dry before the first coat of finish is applied.
These mechanics are still learning.
