Most durable paint type for baseboards and trim
&quot;Two Pack&quot; or &quot;2K&quot; is the hardest paint. It is polyurethane based.
It has a volatile organinc solvent, and outgasses during curing so use lots of ventilation, the stuff is nasty, positive pressure respirators are used in industrial applications.
Clear polyurethane (two part or one part) can be used over existing paint to protect it.
