Question
my husband built a building with cement block buildings. the problem is anything in the building leaning against the wall gets wet. Because my husband stores his firearms and ammunition in there, we need to solve this problem. Can you give me some help on how we might solve this problem.
Thank you for any help

Answer
Hi joyce, the first product that comes to mind is called "Dry-loc" it is a heavy paint that can be applied to inside walls to stop moisture from penetrating.  It can be found at most big box home improvement stores like home depot and lowes.  To keep moisture totally out of a building it is best to have a good paint or mastic on the exterior to stop water before it penetrates the wall. Even if the wall has siding on it I still coat the exterior with mastic prior to the siding installation.  Siding alone will not keep moisture out.  Dry-loc will stop it at the interior of wall face but moisture stays trapped inside the wall which isn't good over the long haul. I hope this information helps feel free to write again regarding this or other matters, sincerely bruce e johnson..bejohnsonconsulting.com
