Basement Walls: To Paint or Not

Hi All

for the past few months I've been racking my brain and those I know about the best approach for my upcoming basement finish project. Luckily I found this forum so I can get more opinions.

I am struggling about whether to DryLoc or apply another masonry paint to the walls before framing.

Here are the details.
I live in Middle TN, I have a combo basement/garage. I will build an interior partition wall to separate the basement side from the garage side. The finished basement area will then have 2 sides below grade and 1 side open to backyard (walkout), 4th side will face garage which is obviously open. Ground slopes dramitically from front of house below grade side to back of house, walk out side.

The house is 3 years old and the exterior concrete block walls were waterproofed. I have monitored the interior walls and have never noticed a single drop of water. There is no humidity issues in my opinion either. One small section of concrete block on the walkout side did have effluence stains.

I will frame with metal stud framing offset from the blocks and plan to insulate with standard batt insulation with paper facing into room.

My question is whether I need to dryloc or similar the entire basement?

thanks for the help.

Doug

That's one of those questions that will yield 50/50 answers. My opinion is, if there is no water and no humidity, why bother?

I'm sorry; what constitutes a green grass state?

I hadn't noticed any humidity problems but I don't have a hygrometer either. Not that it's scientific but I did have some paper backed photo frames hanging directly on the concrete wall and they are as good as new.

ahh, judging by my summer water bill...I could argue that point

so but does a green grass state imply that I'm more likely to have a humidity problem?

I'm a painter so my view my be slighlty slanted but IMO drylok is cheap insurance. I'd apply it if it were me.

green grass states tend to have higher RH!
