If you feel your floor is releasing too much moisture ,perhaps you might consider doing a Epoxy floor paint project in your garage , they are many companys that offer these Epoxy floor systems , they not only do a fantastic job of holding down moisture , but they look good also, RustOlium makes a really good economical kit ,I think under $50.00. for 400-500 sq ft coverage I used this system in both my garages' and I must say it is holding up very well after 2 yrs and I have no moisture problems at all .
