It sat on the bottom of the balcony door. As it was MDF, is was warped, dirty and possibly quite moldy due to our humid climate.

I replaced it with a piece of hardwoord. As my electric saw broke last year and I have not replaced it yet, I had to use the old handsaw and that went quite fast too.

I gave the new baseboard a layer of primer and a layer of white paint.

It fit snugly in the gap below the balcony door and the screw holes were perfectly measured and placed. Installing it took all of two minutes.
