I want to set up a small shelf, about 40x60 cm, next to the sink as a surface above the washing machine. I would prefer to avoid drilling.
The load on the shelf will be a few kilos (electric toothbrush with charger, makeup, hairdryer, etc.).
I understand that PL400 has good adhesion and is strong, but is it really "nail in a tube"?
The shelf will be attached on three sides, will it hold?
