Wide-plank floors and today we're going to talk about one of the most common issues with finishing an oak floor. Typically, before you put on your stain or your finish, you're going to sand your oak floor and often that can result in scratches or sanding marks or swirl marks, they're called across the boards that you actually don't see. Until you begin to finish the floor, you can see here after we've stained this red oak board, a darker brown color that you really begin to see. Some of these scratches come out that's caused by the sanding process and is something we're going to learn how to eliminate today.
Here you have a freshly sanded piece of oak and it appears to be well sanded without any scratches. In the finish, however, one great way to test whether or not your floor has been properly sanded is to take a rag damp with mineral spirits and rub it over the area that you just sanded by making that wood wet you're, going to see whether or not They still scratch in the oak, you don't want to use water as that's going to swell the grain and make the finish take differently. Mineral spirits will reveal the scratches and will evaporate quickly so that you can continue the finishing process in order to eliminate the scratch marks.
In your oak floor that can be caused by sanding. You want to make sure you follow the proper progression of grits, typically to sand an oak floor. You start with a sixty or an 80 grit sandpaper. If you start with an 80 grit, you want to make sure that you go to the next grit available, which is a hundred grit and then to the next grid. After that, which would be a hundred and twenty grit. The reason you typically see scratches in an oak floor after sanding is that somebody skips a grit in the progression, so I may start with eighty, but I jump all the way to 120 or 150 grit by skipping that hundred grit.
I've left the scratches into the oak floor, so you want to start with 80 go to a hundred onto 120 and then, if you really want to make sure that your floor has all the scratches eliminated, you can use a random orbital sander with a very fine Grit, a hundred and fifty or a hundred and eighty grit sandpaper by going through this four or five-step progression, you're really going to ensure that the scratches are eliminated from your oak floor. This is an example of a finely finished oak floor.
