Primer in shed
I just had a shed built, and I want to paint the floor and shelves. (I'm going to use porch paint.) It's bare wood, and first I will prime. My question is should I use an exterior or interior primer? The wood is all inside--it won't be exposed to weather. On the other hand, the shed is uninsulated so it will get hot (really hot) and cold (not so much--I'm in California).
