Simple science, cold concrete + warm, moist air = condensation. The same as when a glass holding a cold drink sweats.

We have been here 10 years and never came close to the condition we are current experiencing.

I am a walker and this morning about 7:45 I went for my usual walk and by the time I was done there was not a dry spot on me, my hair, my clothes, my socks, my shoes, etc. I have sweat before but never as much as this morning. Unbelievable humidity!

Crazy, isn't it?? I am amazed by it. Yes...my lanai floor was wet all day!! Although, it may solve a little mystery I always had in my old home. Sometimes (and for the life of me I can't remember when) I did have little drip marks on my outside sliders. I always (secretly) surmised it was lizard pee...well! It had to be SOMETHING!!:) ...and never gave it much thought. I now wonder if my walls over the sliders were slightly wet and having a little drip now and again. I have a few of those drips on my sliders today, and I can SEE the wet walls. Hmmmm....hahaha!!! :)

Condensation
 

Hi All,
We too noticed the problem yesterday in our front door enclosure area. I thought there was a roof leak somewhere. We called the Warranty Office and Sach's Roofing responded this morning. He had three calls about this for today so far. It was definitely condensation. He has been doing roofing for many years and has never seen this like it was yesterday and today. He too indicated that it was the severe weather change from very cold to warm along with almost 100% humidity. He checked both rooms (den and garage) adjacent to the enclosure and there was no problem. All was ok. He also showed me the front of the house where condensation had formed as well. He was really nice and customer service oriented, as all of the vendors have been that we have had in our home. So I guess the bottom line is "no worries be happy"!

Yes, condensation. Floormasters called my Mom back this morning & said it has been so humid that it is delaying their floor installations.

Like condensation on a glass
 

Same concept of when you have cold water in a glass in a warm room the glass will form condensation.

Today our lanai was soaking wet and as others have mentioned it was two extremes :

Very cold surfaces left over from the frigid temps lately coupled with 100% humidity.

Double check to see what you have in your garage that may be subject to mildew, mold etc.

me too. I thought I had a roof leak over the entry. And why is the lanai table wet? weird.

My garage floor is still wet today. It has been finished with epoxy. Water can be seen beading on at least half the floor. Realize it is humid- but is this normal? It is new construction, closed in mid Dec.

Mine is also still wet...
Built in 1995. Epoxy floor.

Normal:coolsmiley:

NoMoSno- does this happen often? Or is this a weird one time event? Our garage floor has been wet for days. Not just damp but wet- water droplets can be seen, almost puddles.

Only happens when we get a few cold days, followed by warm air, with almost 100% humidity.
I put a fan on the garage floor to help dry it up.

We have epoxy garage floor without any water droplets. Hubby says our insulated garage doors are probably the reason.

oh, yes! lanai floor soaking wet as well as outside walls! Should we do something or just turn on our ac??

Is your lanai open or enclosed? What type of floor do u have? It was very humid today which is the cause of the sweating. If anything, you could run a dehumidifier.
