6 BAD Painting Hacks. These Tips Are NONSENSE!

What happens here

The final 'hack' involves using a nail and hammer (or even a drill, as jokingly suggested) to punch holes in the 'well' or rim of a paint can. The idea is to allow excess paint that accumulates in the rim to drain back into the can. However, this is highly detrimental. Punching holes exposes the raw metal of the can to air and moisture, leading to rust. This rust will then contaminate the paint, especially lighter colors, causing discoloration. Furthermore, these holes prevent the lid from creating an airtight seal, allowing air to get in and causing the paint to dry out prematurely or skin over. A much better practice is to simply wipe excess paint from the rim with a rag before sealing the lid, ensuring the paint remains fresh and uncontaminated.

Goal: Do not punch holes in the rim of a paint can, as it leads to rust contamination, compromises the air seal, and dries out the paint.
