Answer: Wood glue (for optimists). Superglue is great, but your chair will end up stuck to your pants. Duct tape is the solution of despair.
Answer: A liar. Nobody succeeds on the first try. Nobody.
Answer: 2.5 mm². For a 16A circuit, 2.5 mm² is the standard. 1.5 mm² is for lighting. And 6 mm² is if you want to power a data center.
Answer: Hold the nail straight with pliers. Holding the nail straight with pliers prevents it from bending under hammer blows.
Answer: Priming (primer coat). Primer helps the paint adhere, evens out the surface, and reduces the number of coats needed. But you only ever remember it after the first coat goes on patchy.
Answer: Bonding primer. Bonding primer seals the pores of the concrete and creates a receptive surface. Without it, the paint disappears along with your first wish.
Answer: Meeting a precise tightening torque. A torque wrench avoids breaking screws or stripping threads by applying the exact force recommended by the manufacturer.
Answer: It is much coarser and more abrasive. The lower the number, the coarser the grit. You start coarse to remove material and finish fine to smooth.
Answer: A drilling guide and a drill. Without a guide, your hole will follow the path of a drunk pigeon. With a guide, you can finally look your father-in-law in the eye.
Answer: The neighbor who knows everything. He always shows up at the worst moment to tell you: 'You should do it this way…' while you're already in the middle of wrecking everything.
Answer: 10 mm. For 50 kg in plaster, a 10 mm anchor (Molly or expansion type) is recommended. 6 mm? That's for picture frames.
Answer: White vinegar. White vinegar is an excellent natural rust remover for tools.
Answer: 2 × height + tread = 63 cm. Blondel's formula (2H + T = 63 cm) guarantees a comfortable staircase. Without it, you'll get unintended cardio with every flight.
Answer: In the pocket of the pants you wore 3 days ago. The tape measure follows its own organizational logic, totally independent of yours. It'll be there right where you stopped looking.
Answer: Heat until the solder melts on contact with the metal (without glowing red). The right indicator: the solder should melt on contact with the heated metal, not the direct flame. If the copper is glowing red, you've overheated it and the solder won't be evenly distributed.
