Metal shed is definitely a good option, if you take in consideration having a shed in your backyard. Compared with more common and popular wooden shed; the metal shed has several advantages.
a) It can be easily erected
b) More secure
c) Resistant to rot, termites and fire
d) Less expensive
e) Less Maintenance
However, they are prone to condensation. Condensation can be really, a problem for metal sheds. Therefore, you should follow some steps, which can help you to diminish this unpleasant problem.
Let’s see first what is the cause of the condensation.
The main cause of the condensation is the dampness that is present in the shed foundation. This moisture rises in the inside warm air of the shed until touches the metal walls and roof, where it condenses and drips down.
Therefore, the best way to fight against condensation is to prevent the dampness in the shed foundation.
Steps to take:
1. Before a Metal Shed Installation
a) The concrete slab or foundation should not be larger than the shed area.
b) Example: Shed Area = 93” x 70” then Foundation = 96” x 73”
c) Next step is the waterproofing of foundation. That can be realized inserting a moisture-proof membrane at 2” higher than the ground level.
d) After concrete pouring, you should allow time, at least 7 days, for foundation to cure. In this way, you can alleviate the excess of dampness from foundation.
e) After the metal shed installation, it is a good idea to caulk around the inside shed base perimeter. In this way, you will prevent the outside water to seep into inside.
2. If the Metal Shed is already Installed
a) One way to diminish and even eliminate the moisture from your shed is to dismantle and remove the metal shed from its base. Build a wooden floor over the concrete slab but not much larger than the shed base. Then, install the shed back and caulk around the inside shed base perimeter. This is a really smart idea. The wooden floor will allow the air to flow and dry the inside of the shed. However, make sure that water has no possibility to pool under the wooden floor.
b) Clean the inside metal walls of the shed with methylated spirits. Make sure the panels are dry. Using polystyrene tiles lining the inside metal roof of the shed. Check for the proper adhesive for bonding polystyrene to metal. Of course, in this way you will not remove the moisture from inside of your shed, but at least, you will prevent its condensation.
