Touch it up with the same water base semi-gloss. Use a artist brush to pencil it in.

I'd hit that with a random orbital sander until it was gone and feather in a refinish.

I'd lightly sand where the scratch is, apply a few coats of finish, carefully sanding with a flat block between coats (with the grain), then tape off around the boards, lightly sand them and apply a coat. If you're confused with these instructions you can probably search youtube and see how experts use a similar technique to touch up paint chips on cars.

There's a woodworking technique called burnishing where you use a hard object like a hardwood dowel or a burnishing tool to press wood fibers down. Use a short section of hardwood applied with the grain to see if you can reduce the scratch.

9 tips for scratch repair

I'd rub it with the broken edge of a walnut piece (the nut, not walnut wood). It will slightly darken the scratch and make it disappear. After some more scratches appear in your floors you won't notice this one as much.

For your natural red oak floor with a water-based semi-gloss finish, using wood putty is generally recommended over wood filler. Wood putty is better suited for smaller repairs and can be easily colored to match the existing floor color. Here are the best steps to fix your damaged floor:

1. Prepare the Area: Clean the damaged area to remove any debris or dirt.

2. Match the Color: Use a stain or dye to match the color of the putty to your floor.

3. Apply the Putty: Fill the damaged area with the putty using a putty knife.

4. Smooth the Surface: After the putty dries, sand it down to make it level with the surrounding floor.

5. Finish: Apply a new coat of finish to the repaired area to blend it with the rest of the floor.

It's always a good idea to test the putty in an inconspicuous area first to ensure it matches the floor color. If you're unsure about the process or the best products to use, consider consulting a professional for advice.
